    Full Text Available Paluku Bahwere, Kate Sadler, Steve CollinsValid International, Oxford, United KingdomObjective: A prospective descriptive study to assess acceptability and effectiveness of a locally made ready-to-use therapeutic food (RUTF in HIV-infected chronically sick adults (CSA with mid-upper-arm circumference (MUAC <210 mm or pitting edema. Methods: Sixty-three wasted AIDS adults were prescribed 500 g representing ~2600 kcal/day of locally made RUTF for three months and routine cotrimoxazole. Weight, height, MUAC, Karnofsky score and morbidity were measured at admission and at monthly intervals. The amount of RUTF intake and acceptability were assessed monthly.Results: Ninety-five percent (60/63 of the CSA that were invited to join the study agreed to participate. Mean daily intake in these 60 patients was 300 g/person/day (~1590 Kcal and 40 g of protein. Overall, 73.3% (44/60 gained weight, BMI, and MUAC. The median weight, MUAC and BMI gains after three months were 3.0 kg, 25.4 mm, and 1.1 kg/m2, respectively. The intervention improved the physical activity performance of participants and 78.3% (47/60 regained sufficient strength to walk to the nearest health facility. Mortality at three months was 18.3% (11/60.Conclusion: Locally made RUTF was acceptable to patients and was associated with a rapid weight gain and physical activity performance. The intervention is likely to be more cost effective than nutritional support using usual food-aid commodities.Keywords: ready-to-use therapeutic food, community-based intervention, adult, supplementation, HIV, Malawi

  8. Mutation breeding in chickpea

    International Nuclear Information System (INIS)

    Chickpea is an important food legume in Turkey. Turkey is one of the most important gene centers in the world for legumes. Realizing the potential of induced mutations, a mutation breeding programme was initiated at the Nuclear Agriculture Section of the Saraykoy Nuclear Research and Training Center in 1994. The purpose of the study was to obtain high yielding chickpea mutants with large seeds, good cooking quality and high protein content. Beside this some characters such as higher adaptation ability, tolerant to cold and drought, increased machinery harvest type, higher yield, resistant to diseases especially to antracnose and pest were investigated too. Parent varieties were ILC-482, AK-7114 and AKCIN-91 had been used in these experiments. The irradiation doses were 0 (control), 50, 100, 150, 200, 250, 300, 350 and 400 Gy for field experiments, respectively. As a result of these experiments, two promising mutant lines were chosen and given to the Seed Registration and Certification Center for official registration These two promising mutants were tested at five different locations of Turkey, in 2004 and 2005 years. After 2 years of registration experiments one of outstanding mutants was officially released as mutant chickpea variety under the name TAEK-SAGEL, in 2006. Some basic characteristics of this mutant are; earliness (95-100 day), high yield capacity (180-220 kg/da), high seed protein (22-25 %), first pot height (20-25 cm), 100 seeds weight (42-48 g), cooking time (35-40 min) and resistance to Ascochyta blight.

  11. Mutation breeding in chickpea

    International Nuclear Information System (INIS)

    Chickpea is an important food legume in Turkey. Turkey is one of the most important gene centers in the world for legumes. The most widely known characteristic of chickpea is that it is an important vegetable protein source used in human and animal nutrition. However, the dry grains of chickpea, has 2-3 times more protein than our traditional food of wheat. In addition, cheakpea is also energy source because of its high carbohydrate content. It is very rich in some vitamin and mineral basis. In the plant breeding, mutation induction has become an effective way of supplementing existing germplasm and improving cultivars. Many successful examples of mutation induction have proved that mutation breeding is an effective and important approach to food legume improvement. The induced mutation technique in chickpea has proved successful and good results have been attained. Realizing the potential of induced mutations, a mutation breeding programme was initiated at the Nuclear Agriculture Section of the Saraykoey Nuclear Research and Training Center in 1994. The purpose of the study was to obtain high yielding chickpea mutants with large seeds, good cooking quality and high protein content. Beside this some characters such as higher adaptation ability, tolerant to cold and drought, increased machinery harvest type, higher yield, resistant to diseases especially to antracnose and pest were investigated too. Parents varieties were ILC-482, AK-7114 and AKCIN-91 (9 % seed moisture content and germination percentage 98 %) in these experiments. The irradiation doses were 0 (control), 50, 100, 150, 200, 250, 300, 350, 400, 500 ve 600 Gy for greenhouse experiments and 0 (control), 50, 100, 150, 200, 250, 300, 350 ve 400 Gy for field experiments, respectively. One thousand seeds for per treatment were sown in the field for the M1. At maturity, 3500 single plants were harvested and 20 seeds were taken from each M1 plant and planted in the following season.

    With the growing number of GMOs introduced to the market, testing laboratories have seen their workload increase significantly. Ready-to-use multi-target PCR-based detection systems, such as pre-spotted plates (PSP), reduce analysis time while increasing capacity. This paper describes the development and applicability to GMO testing of a screening strategy involving a PSP and its associated web-based Decision Support System. The screening PSP was developed to detect all GMOs authorized in the EU in one single PCR experiment, through the combination of 16 validated assays. The screening strategy was successfully challenged in a wide inter-laboratory study on real-life food/feed samples. The positive outcome of this study could result in the adoption of a PSP screening strategy across the EU; a step that would increase harmonization and quality of GMO testing in the EU. Furthermore, this system could represent a model for other official control areas where high-throughput DNA-based detection systems are needed. PMID:26868555

    Ready-to-use therapeutic foods (RUTFs) are solid foods that were developed by changing the formulation of the existing liquid diet, F-100, recommended by the World Health Organization (WHO) for the rapid catch-up phase of the treatment of children suffering from severe acute malnutrition (SAM). The resulting products proved highly effective in promoting weight gain in both severely and moderately wasted children and adults, including those infected with HIV. The formulation of the existing RUTFs, however, has never been optimized to maximize linear growth, vitamin and mineral status, and functional outcomes. The high milk content of RUTFs makes it an expensive product, and using lower quantities of milk seems desirable. However, the formulation of alternative, less expensive but more effective versions of RUTF faces difficult challenges, as there are uncertainties regarding the effect in terms of protein quality, antinutrient content, and flatulence factors that will result from the replacement of current dairy ingredients by less expensive protein-rich ingredients. The formulation of alternative RUTFs will require further research on these aspects, followed by efficacy studies comparing the future RUTFs to the existing formulations. PMID:25902615

    Ready-to-use therapeutic foods (RUTFs) are a key component of a life-saving treatment for young children who present with uncomplicated severe acute malnutrition in resource limited settings. Increasing recognition of the role of balanced dietary omega-6 and omega-3 polyunsaturated fatty acids (PUFA) in neurocognitive and immune development led two independent groups to evaluate RUTFs. Jones et al. (BMC Med 13:93, 2015), in a study in BMC Medicine, and Hsieh et al. (J Pediatr Gastroenterol Nutr 2015), in a study in the Journal of Pediatric Gastroenterology and Nutrition, reformulated RUTFs with altered PUFA content and looked at the effects on circulating omega-3 docosahexaenoic acid (DHA) status as a measure of overall omega-3 status. Supplemental oral administration of omega-3 DHA or reduction of RUTF omega-6 linoleic acid using high oleic peanuts improved DHA status, whereas increasing omega-3 alpha-linolenic acid in RUTF did not. The results of these two small studies are consistent with well-established effects in animal studies and highlight the need for basic and operational research to improve fat composition in support of omega-3-specific development in young children as RUTF use expands.

  15. Should India Use Commercially Produced Ready To Use Therapeutic Foods (RUTF For Severe Acute Malnutrition (SAM ?

    Directory of Open Access Journals (Sweden)

    2009-02-01

    Full Text Available Globally, nearly 20 million children under five suffer from Severe Acute Malnutrition (SAM, a condition which contributes to one million child deaths annually. In India 48% of children under five years of age are stunted and 43 percent are underweight; almost 8 million suffer from SAM. Malnutrition is not a new problem in India, nor is SAM. Several hospitals and non-government organizations are engaged in community-based management of malnutrition using locally produced/procured and locally processed foods along with intensive nutrition education. These programs enable parents to meet the nutritional requirements of their children with foods that are available at low cost. The Supreme Court of India has also directed the government to universalize the Integrated Child Development Scheme and provide one hot cooked meal to children under six years of age to supplement their nutrition. The blame for the increasing number of severely malnourish children can be laid at the door of policies that have destroyed poor people’s access to food. Nonetheless, there is urgent need to ensure that these children do not die; that they recover and maintain a healthy nutritional status. The current thinking – that a centrally produced and processed Ready-to-Use Therapeutic Food (RUTF should supplant the locally prepared indigenous foods in treatment of SAM – ignores the multiple causes of malnutrition and destroys the diversity of potential solutions based on locally available foods. This position paper has been drafted by Dr. Vandana Prasad, Radha Holla and Dr. Arun Gupta, members of the Working Group for Children Under Six – a joint effort of Jan Swasthya Abhiyan (People’s Health Movement – India and the Right to Food Campaign which been advocating for the last three years with the Indian government for decentralized and community-based strategies to combat and prevent malnutrition in children.

    Five psychrotrophic strains of lactic acid bacteria (Lactobacillus casei, Lact. plantarum and Pediococcus spp.) were isolated from 22 samples of commercial salads. These strains were shown to inhibit Aeromonas hydrophila, Listeria monocytogenes, Salmonella typhimurium and Staphylococcus aureus on MRS agar, in salads and in juice prepared from vegetable salads. Lactobacillus casei IMPCLC34 was most effective in reducing total mesophilic bacteria and the coliform group; Aer. hydrophila, Salm. typhimurium and Staph. aureus disappeared after 6 d of storage, while the counts for L. monocytogenes remained constant. The potential application of antimicrobial-producing lactic acid bacteria as biopreservatives of ready-to-use vegetables is suggested. PMID:8760320

  7. Effect of Gamma Irradiation on the Microflora of Commercial Ready-To-Use (RTU) Salads during Cold Storage

    International Nuclear Information System (INIS)

    Since ready-to-use (RTU) products are not fully cooked, the shelf-life of the product is comparably short and the products are easily spoiled when contaminated with food-borne pathogens. Low-dose gamma irradiation of 0.5, 1, or 2 kGy effectively reduced the total aerobic bacterial counts in 2 Korean manufactured RTU products by 1.63 to 2.95 log CFU/g during cold storage. Irradiation at 2 kGy reduced the psychrotrophic bacterial counts in most of the samples to below the limit of detection (less than 2 log CFU/g). Irradiation at 0.5 kGy completely eliminated Escherichia coli from the commercial RTU samples

    Crop domestication, in general, has reduced genetic diversity in cultivated gene pool of chickpea (Cicer arietinum) as compared with wild species (C. reticulatum, C. bijugum). To explore impact of domestication on symbiosis, 10 accessions of chickpeas, including 4 accessions of C. arietinum, and 3 accessions of each of C. reticulatum and C. bijugum species, were selected and DNAs were extracted from their nodules. To distinguish chickpea symbiont, preliminary sequences analysis was attempted with 9 genes (16S rRNA, atpD, dnaJ, glnA, gyrB, nifH, nifK, nodD and recA) of which 3 genes (gyrB, nifK and nodD) were selected based on sufficient sequence diversity for further phylogenetic analysis. Phylogenetic analysis and sequence diversity for 3 genes demonstrated that sequences from C. reticulatum were more diverse. Nodule occupancy by dominant symbiont also indicated that C. reticulatum (60%) could have more various symbionts than cultivated chickpea (80%). The study demonstrated that wild chickpeas (C. reticulatum) could be used for selecting more diverse symbionts in the field conditions and it implies that chickpea domestication affected symbiosis negatively in addition to reducing genetic diversity.

  10. Imaging techniques applied to quality control of civil manufactured goods obtained starting from ready-to-use mixtures

    Science.gov (United States)

    Bonifazi, Giuseppe; Castaldi, Federica

    2003-05-01

    Concrete materials obtained from the utilization of pre-mixed and ready to use products (central mix-concrete) are more and more used. They represent a big portion of the civil construction market. Such products are used at different scale, ranging from small scale works, as those commonly realized inside and house, an apartment, etc. or at big civil or industrial scale works. In both cases the problem to control the mixtures and the final work is usually realized through the analysis of properly collected samples. Through appropriate sampling it can be derived objective parameters, as size class distribution and composition of the constituting particulate matter, or mechanical characteristics of the sample itself. An important parameter not considered by the previous mentioned approach is "segregation", that is the possibility that some particulate materials migrate preferentially in some zones of the mixtures and/or of the final product. Such a behavior dramatically influences the quality of the product and of the final manufactured good. Actually this behavior is only studied adopting a human based visual approach. Not repeatable analytical procedures or quantitative data processing exist. In this paper a procedure fully based on image processing techniques is described and applied. Results are presented and analyzed with reference to industrial products. A comparison is also made between the new proposed digital imaging based techniques and the analyses usually carried out at industrial laboratory scale for standard quality control.

    International Nuclear Information System (INIS)

    Isotopic and non-isotopic methods were used to quantify below ground nitrogen (BGN) for two winter legumes, fababean (Vicia faba) and chickpea (Cicer arietinum), under glasshouse and field conditions. In the glasshouse study, estimates of BGN for fababean and chickpea, respectively, were 13 and 10% of total plant N (physical recovery), 11 and 52% (soil 15N dilution), 30 and 52% (mass N balance), 39 and 53% (15N-shoot labelling), 37 and 42% (adjusted 15N shoot labelling), and 33 and 43 % (15N balance). In the field experiment, values were 25 and 77% (15N-shoot labelling), 24 and 68% (adjusted 15N shoot labelling) and 29 and 60% (15N balance). When averaged across all estimates (other than physical recovery), BGN of glasshouse-grown plants represented 31% of total plant N for fababean and 48% for chickpea. By comparison, the mean values for BGN as percent of total plant N in the field study using the two methods considered likely to give the most reliable results (adjusted 15N shoot labelling and 15N balance) were 27% for fababean and 64% for chickpea.

    Full Text Available Chickpea proteins are used as ingredients in comminuted sausage products and many oriental textured foods. Rheological behaviour of chickpea protein concentrate was studied using a controlled stress rheometer. The protein dispersion prepared with phosphate buffer at pH 7.0 presented non-Newtonian shear thinning behaviour and rheological data well fitted to the Sisko, Carreau and Cross models. The viscoelastic properties of the chickpea protein suspensions were estimated by measuring the storage and loss moduli in oscillatory frequency conditions (0.1-10 Hz at 20°C. Moreover, thermally induced gelation of the chickpea proteins (16, 24 and 36% was studied at pH 7.0 and 4.5 in the temperature range 50 to 100oC and salt concentration ranging from 0 to 1 M. Gelling behaviour was quantified by means of dynamic rheological measurements. Gels formation was preceded by the decrease of storage modulus and loss moduli, coupled with the increase of the phase angle (delta. The beginning of thermal gelation was influenced by protein concentration, pH and salt level. In all studied cases, storage modulus increased rapidly in the temperature range 70-90°C. All rheological parameters measured at 90°C were significantly higher at pH 4.5 compared to pH 7.0.

    Full Text Available Interest in the development of stripper headers is growing owing to the excessive losses of combine harvesters and costs of manually harvesting for chickpeas. The design of a new concept can enhance the mechanized process for chickpea harvesting. A modified stripper platform was designed, in which passive fingers with V-shape slots removes the pods from the anchored plant. The floating platform was accompanied by a reel to complete the harvesting header. Black-box modeling was used to redesign the functional operators of the header followed by an investigation of the system behavior. Physical models of the platform and reel were modified to determine the crucial variables of the header arrangement during field trials. The slot width was fixed at 40 mm, finger length at 40 mm, keyhole diameter at 10 mm and entrance width at 6 mm; the batted reel at peripheral diameter of 700 mm and speed at 50 rpm. A tractor-mounted experimental harvester was built to evaluate the work quality of the stripper header. The performance of the prototype was tested with respect to losses and results confirmed the efficiency of the modified stripper header for chickpea harvesting. Furthermore, the header with a 1.4 m working width produced the spot work rates of 0.42 ha h-1.

    2015-01-01

    Ready-to-use therapeutic foods (RUTF) are lipid-based pastes widely used in the treatment of acute malnutrition. Current specifications for RUTF permit a high n-6 polyunsaturated fatty acid (PUFA) content and low n-3 PUFA, with no stipulated requirements for preformed long-chain n-3 PUFA. The objective of this study was to develop an RUTF with elevated short-chain n-3 PUFA and measure its impact, with and without fish oil supplementation, on children\\'s PUFA status during treatment of severe acute malnutrition.

  1. Impact of Genomic Technologies on Chickpea Breeding Strategies

    Directory of Open Access Journals (Sweden)

    2012-08-01

    Full Text Available The major abiotic and biotic stresses that adversely affect yield of chickpea (Cicer arietinum L. include drought, heat, fusarium wilt, ascochyta blight and pod borer. Excellent progress has been made in developing short-duration varieties with high resistance to fusarium wilt. The early maturity helps in escaping terminal drought and heat stresses and the adaptation of chickpea to short-season environments. Ascochyta blight continues to be a major challenge to chickpea productivity in areas where chickpea is exposed to cool and wet conditions. Limited variability for pod borer resistance has been a major bottleneck in the development of pod borer resistant cultivars. The use of genomics technologies in chickpea breeding programs has been limited, since available genomic resources were not adequate and limited polymorphism was observed in the cultivated chickpea for the available molecular markers. Remarkable progress has been made in the development of genetic and genomic resources in recent years and integration of genomic technologies in chickpea breeding has now started. Marker-assisted breeding is currently being used for improving drought tolerance and combining resistance to diseases. The integration of genomic technologies is expected to improve the precision and efficiency of chickpea breeding in the development of improved cultivars with enhanced resistance to abiotic and biotic stresses, better adaptation to existing and evolving agro-ecologies and traits preferred by farmers, industries and consumers.

  3. Radiolanthanide-labeled HA particles in the treatment arthritis: ready-to-use cold kits for rapid formulation in hospital radiopharmacy

    International Nuclear Information System (INIS)

    Radiation synovectomy, which involves local intraarticular injection of suitable β- emitting radionuclides in the form of radiocolloids or radiolabeled particulates into the affected synovial joints, has been successfully employed in the treatment of arthritis of different types. Hydroxyapatite (HA) (Ca10(PO4)6(OH)2) is one of the preferred particulates for effective management of synovial inflammation owing to its excellent biocompatibility. A number of lanthanide radioisotopes, like, 90Y, 142Pr, 153Sm, 166Ho, 169Er, 177Lu, etc, decaying by emission of β- particles of varying energies have been proposed for use in radiation synovectomy of various joints. The present paper describes the preparation and evaluation of ready-to-use cold kits of hydroxyapatite (HA) particles of 1-10 μ size for easy and rapid formulation of radiolabeled HA particles using various lanthanide radioisotopes

    Twenty-one boards infested with drywood termites were examined for activity using a Termatrac® motion detector. Termite galleries were identified using a Resistograph drill and treated with one of three ready-to-use (RTU) products. Results indicated that the Termatrac was excellent at locating termite activity but provided 9.5% false negatives. The Resistograph located termite galleries with an average of 4.6 ± 2.7 holes drilled to find at least one gallery in a board. Treatments included three formulations and two active ingredients; a foam (imidacloprid), a dry (fipronil) and an experimental formulation in a pressurized can (fipronil). All treatments provided evidence for a reduction in mean termite populations per board compared to the control. Two treatments provided evidence of elimination of infestation but no formulation eliminated infestations in every board that was treated. The concept of local treatment for drywood termite control is discussed relative to our results. PMID:26467947

    Full Text Available Chickpea (Cicer arietinum L. is an important crop legume plant with high nutritional value. The transcriptomes of desi and wild chickpea have already been sequenced. In this study, we sequenced the transcriptome of kabuli chickpea, C. arietinum (genotype ICCV2, having higher commercial value, using GS-FLX Roche 454 and Illumina technologies. The assemblies of both Roche 454 and Illumina datasets were optimized using various assembly programs and parameters. The final optimized hybrid assembly generated 43,389 transcripts with an average length of 1065 bp and N50 length of 1653 bp representing 46.2 Mb of kabuli chickpea transcriptome. We identified a total of 5409 simple sequence repeats (SSRs in these transcript sequences. Among these, at least 130 and 493 SSRs were polymorphic with desi (ICC4958 and wild (PI489777 chickpea, respectively. In addition, a total of 1986 and 37,954 single nucleotide polymorphisms (SNPs were predicted in kabuli/desi and kabuli/wild genotypes, respectively. The SNP frequency was 0.043 SNP per kb for kabuli/desi and 0.821 SNP per kb for kabuli/wild, reflecting very low genetic diversity in chickpea. Further, SSRs and SNPs present in tissue-specific and transcription factor encoding transcripts have been identified. The experimental validation of a selected set of polymorphic SSRs and SNPs exhibited high intra-specific polymorphism potential between desi and kabuli chickpea, suggesting their utility in large-scale genotyping applications. The kabuli chickpea gene index assembled, and SSRs and SNPs identified in this study will serve as useful genomic resource for genetic improvement of chickpea.

    A study was carried out to establish a detection method for irradiated chickpea and corn by thermoluminescence (TL) method. The leguminous were packed in polyethylene bags and then the packets were irradiated at room temperature at different doses by 60Co gamma source at 1, 4, 8 and 10 kGy. Minerals extracted from the leguminous were deposited onto a clean aluminum disc and TL intensities of the minerals were measured by TL. It was observed that the extracted samples from both leguminous exhibit good TL Intensity and the TL intensity of glow curves of them increased proportionally to irradiation doses. The TL glow curve of both irradiated leguminous presents a single broad peak below 400 °C. The TL trapping parameters glow peaks were estimated by the additive dose (AD), Tm(Ea)-Tstop and computerized glow curve deconvolution (CGCD) methods. The fading characteristics of glow curves were also recorded up to 6 months.

    Poor complementary feeding practices and low-quality complementary foods are significant causes of growth faltering and child mortality throughout the developing world. Ready-to-use foods (RUF) are energy-dense, lipid-based products that do not require cooking or refrigeration that have been used to prevent and treat malnutrition among vulnerable children. The effectiveness of these products in improving child nutritional status depends on household use by caregivers. To identify the key facilitators and barriers that influence appropriate in-home RUF consumption by supplemental feeding program beneficiaries, we conducted individual interviews among caregivers (n = 80), RUF producers (n = 8) and program staff (n = 10) involved in the Byokulia Bisemeye mu Bantu supplemental feeding program in Bundibugyo, Uganda. By documenting caregiver perceptions and feeding practices related to RUF, we developed a conceptual framework of factors that affect appropriate feeding with RUF. Findings suggest that locally produced RUF is well received by caregivers and children, and is perceived by caregivers and the community to be a healthy supplemental food for malnourished children. However, child feeding practices, including sharing of RUF within households, compromise the nutrient delivery to the intended child. Interventions and educational messages informed by this study can help to improve RUF delivery to targeted beneficiaries. PMID:22136223

    A ready-to-use L-ascorbic acid (L-AA) colorimetric strip based on polyaniline (PANI)/polyamide 66 (PA 66) nanofiber/net (NFN) membrane with spider-web-like structure was fabricated through a facile bend electrospinning/netting process. Introduction of PANI component into the membrane turns the strip undergoes a brilliant brown-to-green color transition within 30 min upon incubation with L-AA. Moreover, ascribing to the three-dimensional microscopic structural, continuous pore channels, and distinctive nano-nets structure, the color change that is caused by 50 ppb L-AA can be easily perceived by naked eyes. Furthermore, RGB (red-green-blue) digital parameters that obtained from photographs of the strips were automatically read out via an iPhone. Subsequently, the parameters were converted into a color-difference map and processed statistically through principal component analysis, then used to elaborate standard curve. Combining the map and curve, we realized a method for assaying and quantifying L-AA concentration in real food samples, which avoids the time-consuming sample preparation, expensive laboratory techniques, and specialized personnel needed to carry out conventional analytical methods.

    Over the last decade, isolation and purification of monoclonal antibodies, for diagnostic analysis, have been carried out using the hybridoma expression system. The present study describes a novel example of a detection system using hybridoma cells containing antibody against O1 antigen directly for V. cholerae diagnosis, which is a major health problem in many parts of the world, especially in developing countries. This method has advantages such as simplicity, ease of process, and it does not require manipulation of hybridoma cell. For this approach, an efficient amount of fluorescence calcium indicator, fura 2-AM, was utilized, which emitted light when the intracellular calcium concentration increased as result of antigen binding to specific antibody. More reliable results are obtained via this method and it is considerably faster than other methods, which has the response time of less than 45 s for detection of V. Cholerae O1. Also, the limit of detection was computed to be 50 CFU/mL (cholerae O1. Furthermore, this method was successfully applied to V. cholerae O1 detection in spiked environmental samples, including water and stool samples without any pretreatment. All results reveal that hybridoma cells can provide a valuable, simple, and ready to use tool for rapid detection of other pathogenic bacteria, toxins, and analytes. PMID:27438715

  12. Radiolanthanide-labeled HA particles in the treatment of rheumatoid arthritis. Ready-to-use cold kits for rapid formulation in hospital radiopharmacy

    International Nuclear Information System (INIS)

    Hydroxyapatite (HA) [Ca10(PO4)6(OH)2] particles radiolabeled with a variety of β- emitting lanthanide radionuclides and also pseudolanthanide 90Y have been proposed for the treatment of arthritis. A ready-to-use cold kit of HA particles (1-10 μm size) was developed for fast and convenient formulation of radiolanthanide-labeled HA particles at hospital radiopharmacy. Six radionuclides namely, 169Er, 177Lu, 153Sm, 166Ho, 142Pr and 90Y, having β- emissions of a wide range of energy [Eβ(max) = 0.34-2.28 MeV] were identified and produced by thermal neutron activation. Clinical doses of HA particles labeled with these radionuclides were prepared in high yield (>97 %) and radiochemical purity (>99 %) using the cold kits. Pre-clinical studies of 177Lu-HA carried out in Wistar rats bearing arthritis in knee joints revealed no leakage of the activity from the joints. In preliminary clinical investigation using 333 ± 46 MBq doses of the same preparation, significant improvement in the disease conditions was reported in patients with chronic rheumatoid arthritis of knee joints.

    Hydrogel as three-dimensional (3D) substrate has been employed in miniaturized high throughput protein detection platforms to increase the number of effective antibodies and signal augmentation. However, the high water content of the hydrogel can dilute samples and create barrier to mass transfer, limiting hydrogel height to several microns in most platforms. Moreover, these platforms cannot achieve widespread use in common laboratories as they usually rely heavily on expensive robotic liquid handlers and custom-built components. Here we developed a ready-to-use, easy to store and handle, versatile and multiplex-able 3D scaffold-based immunoassay chip (3D immunoChip) possible for high throughput protein quantification using bench-top equipment in common laboratories. Sample dilution, mass transfer, signal scattering and storage problems can be avoided by using dry scaffolds that regain transparency upon rehydration. When combined with hydrophilic-hydrophobic patterned reagent loading slides, manual high throughput handling of samples can be achieved. As these micro-scaffolds are patterned without barriers in between, simultaneous and effortless washing of all the reaction zones is possible in a Petri dish. Such features aid the 3D immunoChip in saving up to 100 times reagent and about 6 times labour. The 3D immunoChip is able to detect albumin (ALB), as a model analyte, from 5 ng mL(-1) to 1000 ng mL(-1), making it comparable to the commercialized ELISA kit based on a 96-well plate (0.22-400 ng mL(-1)). This thus enables the 3D immunoChip to directly detect ALB secreted by HepaRG cells cultured in a 3D cell culture array chip for high throughput drug hepatotoxicity evaluation, which could potentially accelerate drug screening.

    Full Text Available Understanding developmental processes, especially in non-model crop plants, is extremely important in order to unravel unique mechanisms regulating development. Chickpea (C. arietinum L. seeds are especially valued for their high carbohydrate and protein content. Therefore, in order to elucidate the mechanisms underlying seed development in chickpea, deep sequencing of transcriptomes from four developmental stages was undertaken. In this study, next generation sequencing platform was utilised to sequence the transcriptome of four distinct stages of seed development in chickpea. About 1.3 million reads were generated which were assembled into 51,099 unigenes by merging the de novo and reference assemblies. Functional annotation of the unigenes was carried out using the Uniprot, COG and KEGG databases. RPKM based digital expression analysis revealed specific gene activities at different stages of development which was validated using Real time PCR analysis. More than 90% of the unigenes were found to be expressed in at least one of the four seed tissues. DEGseq was used to determine differentially expressing genes which revealed that only 6.75% of the unigenes were differentially expressed at various stages. Homology based comparison revealed 17.5% of the unigenes to be putatively seed specific. Transcription factors were predicted based on HMM profiles built using TF sequences from five legume plants and analysed for their differential expression during progression of seed development. Expression analysis of genes involved in biosynthesis of important secondary metabolites suggested that chickpea seeds can serve as a good source of antioxidants. Since transcriptomes are a valuable source of molecular markers like simple sequence repeats (SSRs, about 12,000 SSRs were mined in chickpea seed transcriptome and few of them were validated. In conclusion, this study will serve as a valuable resource for improved chickpea breeding.

We used qualitative methods to explore the use, perceptions, and acceptability of RUSF among adult HIV patients in Jimma, Ethiopia. Methods: The study obtained data from direct observations and 24 in-depth interviews with HIV patients receiving RUSF. Results: Participants were generally very motivated to take RUSF and viewed it as beneficial. RUSF was described as a means to fill a nutritional gap, to “rebuild the body,” and protect it from harmful effects of antiretroviral treatment (ART. Many experienced nausea and vomiting when starting the supplement. This caused some to stop supplementation, but the majority adapted to RUSF. The supplement was eaten separately from meal situations and only had a little influence on household food practices. RUSF was described as food with “medicinal qualities,” which meant that many social and religious conventions related to food did not apply to it. The main concerns about RUSF related to the risk of HIV disclosure and its social consequences. Conclusion: HIV patients view RUSF in a context of competing livelihood needs. RUSF intake was motivated by a strong wish to get well, while the risk of HIV disclosure caused concerns. Despite the motivation for improving health, the preservation of social networks was prioritized, and nondisclosure was often a necessary strategy. Food sharing and religious

  18. The effect of adding ready-to-use supplementary food to a general food distribution on child nutritional status and morbidity: a cluster-randomized controlled trial.

    Directory of Open Access Journals (Sweden)

    Lieven Huybregts

    Full Text Available BACKGROUND: Recently, operational organizations active in child nutrition in developing countries have suggested that blanket feeding strategies be adopted to enable the prevention of child wasting. A new range of nutritional supplements is now available, with claims that they can prevent wasting in populations at risk of periodic food shortages. Evidence is lacking as to the effectiveness of such preventive interventions. This study examined the effect of a ready-to-use supplementary food (RUSF on the prevention of wasting in 6- to 36-mo-old children within the framework of a general food distribution program. METHODS AND FINDINGS: We conducted a two-arm cluster-randomized controlled pragmatic intervention study in a sample of 1,038 children aged 6 to 36 mo in the city of Abeche, Chad. Both arms were included in a general food distribution program providing staple foods. The intervention group was given a daily 46 g of RUSF for 4 mo. Anthropometric measurements and morbidity were recorded monthly. Adding RUSF to a package of monthly household food rations for households containing a child assigned to the intervention group did not result in a reduction in cumulative incidence of wasting (incidence risk ratio: 0.86; 95% CI: 0.67, 1.11; p = 0.25.

  20. Screening of chickpea advanced lines for sources of resistance against blight and wilt two major diseases of chickpea

    International Nuclear Information System (INIS)

    Chickpea (Cicer arietinum L.) an important food legume, ranks third in the world. In Pakistan yield of chickpea is low due to the prevalence of wilt and blight diseases - the two destructive diseases. The control measures available are not feasible and economical, except to exploit host plant resistance mechanism to identify the sources of resistance in existing chickpea germplasm. Fifty four advance chickpea genotypes were screened in blight screening nursery and wilt sick plot. Out of total 54 genotypes 23 were resistant and 16 were moderately resistant to Ascochyta blight disease. Among 23 resistant genotypes; K0058-09, K0062-09, K0066-09, D095-09, K07A005, BK05A015 and BK04A013 had disease rating mean of 3. The results of early wilt showed 19 genotypes as highly resistant and 15 as resistant. The genotypes K0070-09, BKK17106, CH 65/02 and BK04A013 were highly susceptible to wilt during early pathogen infection at seedling stage while the genotypes K0063-09, BKK17106 and BK04A013 were susceptible during late season. Resistance sources identified could be exploited directly and also may be transferred through hybridization to high yielding disease susceptible genotypes. (author)

  2. Fate and effects of lindane in a chickpea field

    International Nuclear Information System (INIS)

    The effect of lindane on non-target organisms and the concentrations of its residues in soil and the chickpea crop were investigated over three years. Lindane had adverse effects on some elements of the ecosystem. Ants (Formicidae), spiders (Aranae) and beetles (Carabidae), to a lesser extent, were more affected than Collembola. Organic matter, buried in non-degradable open-mesh bags in the plots, was slightly more degraded in the control plots than in the sprayed plots suggesting that the soil microflora and microfauna had been inhibited by the lindane. However, it was shown by chemical analyses that lindane was degraded in both soils and plants to one tenth of the original concentrations after application in 2 months and 1 month, respectively. Some concentrations (0.2-1.2 mg kg-1) of lindane were found in the harvested grain of the chickpea plants. (author). 1 ref., 6 tabs

    A hallmark trait of chickpea (Cicer arietinum L.), like other legumes, is the capability to convert atmospheric nitrogen (N2) into ammonia (NH3) in symbiotic association with Mesorhizobium ciceri. However, the complexity of molecular networks associated with the dynamics of nodule development in chickpea need to be analyzed in depth. Hence, in order to gain insights into the chickpea nodule development, the transcriptomes of nodules at early, middle and late stages of development were sequenced using the Roche 454 platform. This generated 490.84 Mb sequence data comprising 1,360,251 reads which were assembled into 83,405 unigenes. Transcripts were annotated using Gene Ontology (GO), Cluster of Orthologous Groups (COG) and Kyoto Encyclopedia of Genes and Genomes (KEGG) metabolic pathways analysis. Differential expression analysis revealed that a total of 3760 transcripts were differentially expressed in at least one of three stages, whereas 935, 117 and 2707 transcripts were found to be differentially expressed in the early, middle and late stages of nodule development respectively. MapMan analysis revealed enrichment of metabolic pathways such as transport, protein synthesis, signaling and carbohydrate metabolism during root nodulation. Transcription factors were predicted and analyzed for their differential expression during nodule development. Putative nodule specific transcripts were identified and enriched for GO categories using BiNGO which revealed many categories to be enriched during nodule development, including transcription regulators and transporters. Further, the assembled transcriptome was also used to mine for genic SSR markers. In conclusion, this study will help in enriching the transcriptomic resources implicated in understanding of root nodulation events in chickpea. PMID:27348121

    The chickpea and pigeonpea are protein-rich grain legumes used for human consumption in many countries. Grain yield of these crops is low to moderate in the semi-arid tropics with large variation due to high GxE interaction. In the Indian subcontinent chickpea is grown in the post-rainy winter season on receding soil moisture, and in other countries during the cool and dry post winter or spring seasons. The pigeonpea is sown during rainy season which flowers and matures in post-rainy season. The rainy months are hot and humid with diurnal temperature varying between 25 and 35°C (maximum) and 20 and 25°C (minimum) with an erratic rainfall. The available soil water during post-rainy season is about 200-250 mm which is bare minimum to meet the normal evapotranspiration. Thus occurrence of drought is frequent and at varying degrees. To enhance productivity of these crops cultivars tolerant to drought need to be developed. ICRISAT conserves a large number of accessions of chickpea (>20,000) and pigeonpea (>15,000). However only a small proportion (crop improvement programs mainly due to non-availability of reliable information on traits of economic importance. To overcome this, core and mini core collections (10% of core, 1% of entire collection) have been developed. Using the mini core approach, trait-specific donor lines were identified for agronomic, quality, and stress related traits in both crops. Composite collections were developed both in chickpea (3000 accessions) and pigeonpea (1000 accessions), genotyped using SSR markers and genotype based reference sets of 300 accessions selected for each crop. Screening methods for different drought-tolerant traits such as early maturity (drought escape), large and deep root system, high water-use efficiency, smaller leaflets, reduced canopy temperature, carbon isotope discrimination, high leaf chlorophyll content (drought avoidance), and breeding strategies for improving drought tolerance have been discussed.

    Full Text Available Chickpea (Cicer arietinum L. is one of the most important legumes grown in Asia. Though the area under this crop is more, the average yield per hectare is low because of several biotic and abiotic factors. Among them, the wilt caused by Fusarium oxysporum f.sp. ciceri is most destructive seed and soil borne disease. (Haware et al., 1986 which threatens successful cultivation of chickpea and causes severe losses in chickpea growing areas. (Grewal et al.,1974b and Singh et al.,1977. Different insecticides and herbicides were tried under in vitro, the insecticides Emamectin benzoate 5% SG, Imidachloprid 75% WP, Quinalphos 25% EC, Entrust 80% WP were used in three different concentrations. Among these highest per cent growth of inhibition of Fusarium oxysporum f.sp. ciceri was observed in Imidacloprid 0.3g (50.92% followed by Emamectin benzoate 0.05 mg (35.55%. The herbicides viz., Pendimethalin 30%EC, Imazathaphyr 10% SL, 2,4-D sodium salt 80%WP, Metsulfuron methyl 20% WG were used in three different concentrations, highest per cent growth of inhibition of Fusarium oxysporum f.sp. ciceri was observed in Pendimethalin 0.5ml (73.33%, followed by Pendimethalin 0.4ml (65.55%.

    The influence of a diet of couscous with chickpeas, a traditional Tunisian meal, or one providing iron as ferrous sulfate, on the utilization of 59Fe was evaluated in studies with rats. The iron content of the couscous and chickpea preparation was 30 mg/kg dry weight. There was no difference in the relative absorption of iron from ferrous sulfate or couscous with chickpeas, suggesting that iron from this preparation may be a good dietary source of nonheme iron for rats. Couscous and chickpeas consumption in Tunisia are estimated at 13.3 and 3.2 kg per capita/year, respectively. Our results in rats indicate that these foods could contribute a large proportion of an individual's iron requirement. We conclude that the plant foods, especially the chickpeas, can be excellent sources of dietary-available iron. PMID:1530281

    Pulses (pea, chickpea, lentil, bean) are an important source of food proteins. They contain high amounts of lysine, leucine, aspartic acid, glutamic acid and arginine and provide well balanced essential amino acid profiles when consumed with cereals. The influence of partial substitution of wheat flour with chickpea flour at the levels of 10, 20 and 30 % was carried out to study their pasting properties and bread making quality. Pasting properties were determined using Micro Visco-Amylo-Graph Analyser and Farinograph. The pasting temperature increased with increase chickpea flour concentration and the temperature of pasting ranged between 62 to 66.5 °C. No peak of viscosity curve was found for pure chickpea flour and have higher pasting temperature than pure wheat flour. Chickpea flour addition increased the water absorption and dough development time (p flour in dough affected bread quality in terms of volume, internal structure and texture. The color of crust and crumb got progressively darker as the level of chickpea flour substitution increased. While the substitution of wheat flour with 10 % chickpea flour gave loaves as similar as control. PMID:25190845

  13. Genetic Improvement of Chickpea (Cicer arietinum L.) Using Induced Mutations

    International Nuclear Information System (INIS)

    The main target of chickpea breeding programmes has been to develop high yielding cultivars. In an attempt to induce genetic variability for improvement of locally popular chickpea cultivar Vijay (Phule G-81-1-1), we employed three well known mutagens, sodium azide (SA), ethyl methane sulphonate (EMS) and gamma radiation (GR). The objective was to provide genetic variability in the yield contributing traits that can be exploited for a genetic improvement of chickpea. Seeds of Chickpea cultivar Vijay were treated with three different concentrations / doses of SA (2, 3 and 4 mM), EMS (8, 12 and 16 mM) and gamma radiations (400, 500 and 600 Gy). In M1 generation no dominant mutations were observed, many different mutants were screened and isolated in M2 generation such as chlorophyll mutations (alnina, chlorina and xantha); leaf mutations (gigas, compact and curly); pod mutations (small, roundish, gigas and narrow elongated); seed mutations (green, dark brown, rough seed coat); flower mutations (white flower and open); morphological mutations (early, sterile, tall and gigas). True breeding mutant lines in M3 generation differed considerably in their quantitative traits from the parent cultivar. The early mutant lines matured 10 days earlier than the parent variety. The range in plant height was expanded from 0.02 to 14.91cm. Gigas mutant lines obtained after 400 Gy gamma irradiation were the tallest (44.44cm), with a 2-3 fold increase in pod and seed size over the control. Mutagenic treatments also caused changes in seed size and seed coat. Considerable genotypic variation was observed with regards to the number of seeds and pods per plant. Small leaf mutants showed double the number of seeds and pods per plant. As a result of mutagenic treatments, genetic variation was induced in mutants with respect to different quantitative characters. Induced mutant lines showed both positive and negative increase in the quantitative traits. Variation was also observed for crude

  14. Development of an early maturing chickpea variety, BINASOLA-3

    International Nuclear Information System (INIS)

    Chickpea has higher yield potential, more important nutrients and diversified use than all other pulse crops in Bangladesh. Nevertheless, farmers are not very interested in growing this crop because the varieties have a long maturity period, small seed size and poor seed yielding. For this reason huge amounts of chickpea seeds are imported every year in exchange for valuable foreign currency. A mutation-breeding program was undertaken at Bangladesh Institute of Nuclear Agriculture (BINA) in 1989 to develop an early maturing, large seeded and high yielding variety of chickpea. Seeds of the two exotic lines G-97 (now Binasola-2) and G-319 were treated with gamma-rays, sodium azide and a combination of the two mutagens. The following doses of gamma rays: 0, 200, 300, 400 and 500 Gy, concentrations of sodium azide: 0.4 mM, and combined doses: 200 Gy+0.4 mM, 300 Gy+0.4 mM, 400 Gy+0.4 mM and 500 Gy+0.4 mM were used. In the first year, the treated seeds were grown dose-wise and raised as M1 generation during 1989. M2 seeds were harvested from 4,542 individual M1 plants. These were grown in plant- progeny- rows in M2 generation. Eighty-seven individual M2 plants were selected, from which 16 M4 lines were further selected and put into preliminary observation trials in M4. Among them, one elite mutant L-84, which was derived from a single plant in the population of the 200 Gy gamma-ray treated G-97 was tested in M5, M6 and M7 along with other mutants and its parent. Finally the mutant was evaluated in advanced, zonal yield trials and farmers field trials in the following generations from 1995-2001 along with two selected lines and three released varieties (Hyprosola, Binasola-2 and Barisola-3). All the selected lines were grown at different agro-ecological zones in Bangladesh to observe the yield and other potentiality. Mutant performance was evaluated under two management practices i.e., Research management and Farmers' management. In the research management practices, NPK

    In the past few years, there are number of researchers carrying out their research on the excipients derived from polysaccharides and some of these researches show that natural excipients are comparable and can serve as an alternative to the synthetic excipients. Hence, the objectives of this research are to characterize the naturally sourced chickpea starch powder and to study the pharmaceutical excipient behavior of chickpea starch in gliclazide immediate release (IR) tablets. In this research, the binding properties of chickpea starch were compared to that of povidone, whereas the disintegrant properties of chickpea starch were compared to those of crospovidone, croscarmellose sodium and sodium starch glycolate. Flow property of chickpea starch was assessed with the measurement of bulk density, tapped density, compressibility index and angle of repose. Calibration curve for gliclazide in phosphate buffer pH 7.4 was developed. Gliclazide IR tablets were then produced with direct compression method. Physicochemical characteristics of the tablets, including thickness, tablet weight uniformity, hardness, disintegration time and friability were evaluated. Then, in vitro dissolution studies were performed by following United States Pharmacopeia (USP) dissolution method. The dissolution results were analyzed and compared with t30, t50, dissolution efficiency (DE). Lastly, drug-excipient compatibility studies, including Fourier transform infrared (FTIR) spectroscopic analysis and differential scanning calorimetric (DSC) analysis were carried out. Fair flow property was observed in the chickpea starch powder. Furthermore, the tablets produced passed all the tests in physicochemical characteristics evaluation except hardness and disintegration test. Additionally, in vitro dissolution studies show that chickpea starch acted as a disintegrant instead of a binder in gliclazide IR tablets and its disintegrant properties were comparable to those of crospovidone, croscarmellose

    Full Text Available ABSTRACT The study of outpatient treatment of severe malnourished children with therapeutic food: Formula-100 (F-100 and Ready To Use Therapeutic Food (RUTF had been conducted. The purpose was to optimize the growth of severe malnourished children. Formula-100, milk-based, has been used in health centers. While RUTF, lipid based, has been widely used to improve the nutritional status of severe malnourished children in African countries. The design of this study was quasi experiment and located in ten health centers in Bogor and Subang Regency. Samples were severe malnutrition children, aged 10-54 months with Weight (W / Height (H indicator <-3,0 Z-scores or W/H <-2,0 Z-scores with clinical signs of severe malnutrition. There were two treatment groups: F-100 and RUTF which were given to 39 children in each group for 6 weeks. Data collected were anthropometric, consumption of nutrients, diseases and socio-economics aspects, then data were analyzed using t test. Result showed that before treatment the mean of W/H both groups were <-3,0 Z-scores which catagorized as severe wasted, while after treatment the mean became >-3,0 Z-scores which was catagorized wasted. The improvement of nutritional status (W/H between the RUTF and F-100 group were not significantly different (p>0,05. Almost all of nutrients consumption in both groups fulfilled the recommended dietary allowances, and the nutrient adequancy in both groups were not significantly different after treatment (p>0,05. Therefore RUTF can be used as alternative of F-100. The advantages of RUTF were lower price and containedmore vitamines and minerals compared to F-100.

    Prevalence of obesity and type-2-diabetes requires dietary manipulation. It was hypothesized that wheat-legume-composite breads will reduce the spike of blood glucose and increase satiety. Four pan bread samples were prepared: White bread (WB) as standard, Whole-wheat bread (WWB), WWB supplemented with chickpea flour at 25 % (25%ChB) and 35 % (35%ChB) levels. These breads were tested in healthy female subjects for acceptability and for effect on appetite, blood glucose, and physical discomfort in digestion. The breads were rated >5.6 on a 9-point hedonic scale with WB significantly higher than all other breads. No difference in area under the curve (AUC) for appetite was found, but blood glucose AUC was reduced as follows: 35%ChB 25%ChB = WWB or 35%ChB. We conclude that addition of chickpea flour at 35 % to whole wheat produces a bread that is acceptable to eat, causing no physical discomfort and lowers the glycemic response. PMID:25829607

  1. 'CM 88' - A multiple disease resistant chickpea mutant variety

    International Nuclear Information System (INIS)

    Full text: Chickpea is the most important grain legume crop of Pakistan. Ascochyta blight (Ascochyta rabiei) and Fusarium wilt (Fusarium oxysporum F. sp cicer) are most serious diseases, having the potential to devastate a crop. A multiple disease resistant and high yielding mutant CM 88 has been developed through 100 Gy gamma irradiation treatment of variety 'C 727'. This was once a widely grown and popular variety, which lost its resistance to Ascochyta and was replaced. The selection of mutants was performed in the M2 generation grown in the Ascochyta blight nursery and sixteen mutants were selected. In the subsequent generations CM 88 proved resistant to both Ascochyta blight and Fusarium wilt, and exhibited superiority in agronomic characteristics. CM 88 was also tested for many years in the various yield trials on research stations and farmers fields throughout the country. In these trials it out yielded both the parent and standard varieties. The mutant CM 88 has been approved by the Punjab Seed Council on 27 October 1994 for general cultivation in the Punjab Province, especially the Thal area which accounts for more than 70% of the area under chickpea cultivation.

    Full Text Available Ascochyta blight (AB caused by Ascochyta rabiei (Pass. Labr. is an important and widespread disease of chickpea (Cicer arietinum L. worldwide. The disease is particularly severe under cool and humid weather conditions. Breeding for host resistance is an efficient means to combat this disease. In this paper, attempts have been made to summarize the progress made in identifying resistance sources, genetics and breeding for resistance, and genetic variation among the pathogen population. The search for resistance to AB in chickpea germplasm, breeding lines and land races using various screening methods has been updated. Importance of the genotype × environment (GE interaction in elucidating the aggressiveness among isolates from different locations and the identification of pathotypes and stable sources of resistance have also been discussed. Current and modern breeding programs for AB resistance based on crossing resistant/multiple resistant and high-yielding cultivars, stability of the breeding lines through multi-location testing and molecular marker-assisted selection method have been discussed. Gene pyramiding and the use of resistant genes present in wild relatives can be useful methods in the future. Identification of additional sources of resistance genes, good characterization of the host–pathogen system, and identification of molecular markers linked to resistance genes are suggested as the key areas for future study.

    Chickpea is the world’s third most important pulse crop and India produces 75% of the world’s supply. Chickpea seeds are attacked by Callosobruchus maculatus and C. chinensis which cause extensive damage. The -amylase inhibitor gene isolated from Phaseolus vulgaris seeds was introduced into chickpea cultivar K850 through Agrobacterium-mediated transformation. A total of 288 kanamycin resistant plants were regenerated. Only 0.3% of these were true transformants. Polymerase chain reaction (PCR) analysis and Southern hybridization confirmed the presence of 4.9 kb -amylase inhibitor gene in the transformed plants. Western blot confirmed the presence of -amylase inhibitor protein. The results of bioassay study revealed a significant reduction in the survival rate of bruchid weevil C. maculatus reared on transgenic chickpea seeds. All the transgenic plants exhibited a segregation ratio of 3:1.

    Full Text Available Chickpea flour is a good source of proteins, fibers, minerals and other bioactive compounds and it could be an ideal ingredient for improve the nutritional value of bread and bakery products. The aim of this study was to supplement wheat flour (WF with various levels of chickpea flour (CF in order to obtain bread with good nutritional and quality characteristics. Four experimental variants obtained by substituting wheat flour with different proportions (0%, 10%, 20%, and 30% of chickpea flour were used. The results showed a valuable increment in bread protein and fiber content. The volume of the breads decreased as the level of chickpea flour (CF increased due the dilution of gluten content in the blend and due to the interactions among fiber components, water and gluten. Nevertheless, substitution at 10%, 20% and 30%, gives parameter values at least as good as the control sample (WFB and produces acceptable bread, in terms of weight, volume and sensorial properties.

    Pulses should be part of a healthy diet, and it is also becoming clear that they have health-promoting effects. Nevertheless, most studies on the bioactive or health-promoting properties of pulses have been carried out using soybeans. We have studied cell growth-regulating properties, which may be responsible for anti-cancer properties, in chickpea seeds. Chickpea seeds are a staple in the traditional diet of many Mediterranean, Asian, and South and Central American countries. In addition, chickpea seeds have industrial applications since they can be used for the preparation of protein concentrates and isolates. The cell lines Caco-2 (epithelial intestinal) and J774 (macrophages) have been exposed to chickpea seed extracts and protein preparations in order to screen the different chickpea fractions for effects on cell growth. Both cell growth-promoting and cell growth-inhibiting effects were found. Most interestingly, a fraction soluble in ethanol and acetone specifically and almost completely inhibited the growth of Caco-2 cells exhibiting a cancerous phenotype. It is concluded that chickpea seeds are a source of bioactive components and deserve further study for their possible anti-cancer effect. PMID:15298756

  13. A high yielding, better quality chickpea mutant variety 'NIFA-95'

    International Nuclear Information System (INIS)

    Chickpea or gram (Cicer arietinum L.) is an important legume crop of Pakistan, grown on over one million hectares annually. The national average yield of the crop is very low (0.5 t/ha) and thus the country had to spent about 2 billion rupees ($ 50 million) on import of pulses. The main causes of low yield are non-availability of genetic sources for resistance to various diseases especially gram blight Ascochyta rabiei (Pass.) Lab., insect pest (Pod borer) and non-adoption of proper production technology by the farmers. This calls for earnest efforts of breeders to evolve high yielding and disease resistant varieties of chickpea for provision of quality seeds to the farming community to increase production of this important crop. Seeds of a highly blight susceptible variety '6153' were irradiated at 200 Gy dose of gamma radiation in 1985 and the promising mutant line CMN-446-4 was selected in M3 generation on the basis of disease resistance, greater number of pods and better plant type. After confirmation of its resistance to blight in M4 and M5, the mutant line was evaluated in various trials at different locations. In the advanced and zonal yield trials during 1993-95, the line CMN-446-4 produced the highest grain yield of 2,600 kg/ha as compared to the rest of the mutants and varieties. The line was also evaluated in the chickpea national uniform yield trial, conducted on over 11 locations in the country during 1993-94. In this trial, the mutant line ranked 3rd by producing an average yield of 1,528 kg/ha as compared to the two check varieties 'Punjab-91' (1,316 kg/ha) and 'Paidar-91' (1,391 kg/ha). The mutant line CMN-446-4 is moderately resistant to gram blight, highly resistant to stored pest (pulse beetle), contains 25.3% more protein as compared to the parental variety 6153 and is also better in nitrogen fixing capacity.The proposal for release of the mutant line CMN-446-4 as a new variety under the name 'NIFA-95' for general cultivation in the rainfed area

    Species of Pythium isolated from rotted chickpea seeds and damped-off seedlings and chickpea soils at experimental field of Agriculture faculty of Tehran University in Karaj area that caused seed rot and preemergence damping-off of chickpea were Pyhium ultimum var. ultimum. One of the most important of soilborne fungal pathogens of the chickpea in Iran is seed rot and preemergence damping-off caused by Pythium ultimum Trow. Consequently, growers can expect as much as > 80% reduction in stand and yield if measures are not taken to control Pythium. Currently, most commercial seeds of chickpea are treated with pesticides. Fluorescent pseudomonads applied to seed are known to reduce soilborne diseases of chickpea caused by Pythium spp. In this study rotted chickpea seeds and diseased seedlings and soil samples were collected from experimental field in Karaj. Soils and roots used as sources of bacteria were collected from field. Fluorescent pseudomonads were isolated by plating samples on S1 and King's Medium B (KMB). Bacteria were preserved in 0.1 M MgSO4 for long-term storage; and NAG (containing 2% glucose) slants and plates at 4 degrees C short-term storage. Of 20 fluorescent pseudomonads isolated on S1 medium, 2 isolates selected for next tests. All strains significantly increased emergence as compared to the infested control in greenhouse trial; isolate Pf-4 consistently provided the best protection against Pythium. Seedling emergence from all bacteria seed treatments was statistically lower than the chemical treatments. All strains significantly increased fresh weight of chickpea as compared to the infested control in greenhouse trial. Seed treatment with metalaxyl were statistically better than captan in sterilized soil. In nonsterilized soil collected from the field artificially infested with P. ultimum, all strains significantly increased fresh weight of chickpea as compared to the infested control in greenhouse trial.

    This work was designed to evaluate whether external application of nitric oxide (NO) in the form of its donor S-nitroso-N-acetylpenicillamine (SNAP) could mitigate the deleterious effects of NaCl stress on chickpea (Cicer arietinum L.) plants. SNAP (50 μM) was applied to chickpea plants grown under non-saline and saline conditions (50 and 100 mM NaCl). Salt stress inhibited growth and biomass yield, leaf relative water content (LRWC) and chlorophyll content of chickpea plants. High salinity increased electrolyte leakage, carotenoid content and the levels of osmolytes (proline, glycine betaine, soluble proteins and soluble sugars), hydrogen peroxide (H2O2) and malondialdehyde (MDA), as well as the activities of antioxidant enzymes, such as superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and glutathione reductase in chickpea plants. Expression of the representative SOD, CAT and APX genes examined was also up-regulated in chickpea plants by salt stress. On the other hand, exogenous application of NO to salinized plants enhanced the growth parameters, LRWC, photosynthetic pigment production and levels of osmolytes, as well as the activities of examined antioxidant enzymes which is correlated with up-regulation of the examined SOD, CAT and APX genes, in comparison with plants treated with NaCl only. Furthermore, electrolyte leakage, H2O2 and MDA contents showed decline in salt-stressed plants supplemented with NO as compared with those in NaCl-treated plants alone. Thus, the exogenous application of NO protected chickpea plants against salt stress-induced oxidative damage by enhancing the biosyntheses of antioxidant enzymes, thereby improving plant growth under saline stress. Taken together, our results demonstrate that NO has capability to mitigate the adverse effects of high salinity on chickpea plants by improving LRWC, photosynthetic pigment biosyntheses, osmolyte accumulation and antioxidative defense system.

  2. Gamma rays induced bold seeded high yielding mutant in chickpea

    International Nuclear Information System (INIS)

    In pulses especially in chickpea (Cicer arietinum L.), genetic variability has been exhausted due to natural selection and hence conventional breeding methods are not very fruitful. Mutation techniques are the best methods to enlarge the genetically conditioned variability of a species within a short time and have played a significant role in the development of many crop varieties. Investigations on the effects of ionizing radiations and chemical mutagens in induction of macro-mutations have received much attention owing to their utmost importance in plant breeding. The present study reports a bold seeded mutant in chickpea, the most dominating pulse crop on the Indian subcontinent. Fresh seeds of chickpea variety 'Pusa-212' were procured from IARI, New Delhi and treated with different doses/concentrations of gamma rays (60Co source at NBRI, Lucknow) and ethyl methanesulphonate (EMS), individually as well as in combination, to raise the M1 generation. Seeds of M1 plants were sown to raise M2 plant progenies. A bold seeded mutant was isolated from 400 Gy gamma ray treatments. The mutant was confirmed as true bred, all the mutant seeds gave rise to morphologically similar plants in M3, which were quite distinct from the control. The bold seeded mutant showed 'gigas' characteristics and vigorous growth. The plant remained initially straight but later on attained a trailing habit due to heavy secondary branching. The leaves, petioles, flowers, pods and seeds were almost double that of the parent variety, in size. The flowering occurred 10 days later than the parent and maturity was also delayed accordingly. Observations were recorded on various quantitative traits. Plant height and number of primary branches showed a significant improvement over the parent. It is interesting to note that the number of pods and number of seeds per pod significantly decreased. However, the hundred seed weight (31.73±0.59g) in the mutant plants was more than double in the parent variety

    Full Text Available The article presents materials on comparative study of the nutritional value of chickpeas and peas which are widespread in the arid zone of the Southern Urals. The scheme of the scientific and economic experiments involved the assessment of yield formation of chickpeas and peas during the vegetation. The study showed that different varieties of chickpea and pea have considerable difference in the content of nutrients. The amount of crude protein in the pea grain ranged from 25.1 to 26.8%, and chickpea – 21.7 - 22.9%. With regard to the fat, its highest concentration was in chickpea grain - 3.63%, on average, which is 1.16% higher than on average in the pea grain. The chemical composition of the pea and chickpea grain of different varieties points to differences in their composition and homogeneity within the culture. Basing on the study, we recommend to sow chickpea and pea grain in the middle of May to obtain the highest yield, this, in turn, has a positive effect on the nutritional value of the crops. When selecting plants for cultivation in the conditions of the Southern Urals, it is preferable to choose the variety of Madonna pea, which has a higher potential for yield than the chickpea variety Krasnokutsky-123. It has been experimentally found that chickpea grain has better moisture-retaining power in a bound condition during the vegetation period as compared to the relevant characteristics of pea grain, which is a positive drought-resistant value of crop. In structural elements of the harvest the peas showed the trend of the highest rates in comparison with the corresponding elements in chickpeas

    The linear and volumetric expansion of chickpea seeds during water absorption at 20, 30, 50, 70, 85 and 100°C was studied. Length, width and thickness of chickpea seeds linearly increased with the increase in moisture content at all temperatures studied, where the greatest increase was found in length. Two different mathematical approaches were used for the determination of the expansion coefficients. The plots of the both linear and volumetric expansion coefficients versus temperature exhibited two linear lines, the first one was through 20, 30 and 50ºC and the second one was trough 70, 85 and 100ºC. The crossing point (58ºC) of these lines was very close to the gelatinisation temperature (60ºC) of chickpea starch.

    Full Text Available Proteomic analysis was employed to map the seed storage protein network in landrace and cultivated chickpea accessions. Protein extracts were separated by two-dimensional gel electrophoresis (2D-GE across a broad range 3.0–10.0 immobilized pH gradient (IPG strips. Comparative elucidation of differentially expressed proteins between two diverse geographically originated chickpea accessions was carried out using 2D-GE coupled with mass spectrometry. A total of 600 protein spots were detected in these accessions. In-gel protein expression patterns revealed three protein spots as upregulated and three other as downregulated. Using trypsin in-gel digestion, these differentially expressed proteins were identified by matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF-MS which showed 45% amino acid homology of chickpea seed storage proteins with Arabidopsis thaliana.

    Full Text Available Basic rheological property (force relaxation of a single kernel of chickpea under uni-axial compression was studied. Information on the force relaxation behaviour of chickpea kernels is not available. Meanwhile, no papers was found to study the effects of number of loadings on stress relaxation behaviour of grains and fruits. In this study the effects of moisture content and number of loadings were studied on force relaxation behaviour of chickpea kernels. The results showed that the chickpea kernels had a time dependent behaviour similar to other viscoelastic materials. The three-term Maxwell model with a maximum relative difference (MRD of 5% and R2 higher than 0.997 was chosen as the best fit equation to the relaxation data. Moisture content had a decreasing effect on the first term of the three-term Maxwell model (F1, t1, but the number of loadings had an increasing effect on the first term of the Maxwell model. For all moisture contents and number of loadings, the grain tissue dissipates a major proportion of the initially applied force at a relatively slow rate. As the number of loading increases, the kernel becomes more elastic. Consequently, more force was required to maintain a certain deformation level. A master curve was proposed to determine the force relaxation behaviour of the chickpea kernels at moisture contents between 6.7 and 18% for 1 to 9 cycles of loadings. The Peleg and Pollak model was unsatisfactory for representing the relaxation force for chickpea kernels.

    Full Text Available Salinity is one of the major stresses especially in arid and semiarid regions, which severely limit crop production. It impairs seed germination, reduces nodule formation, retards plant development and reduce crop yield. Salinity affects germination and physiology of crops due to osmotic potential which prevents water up take and by toxic effect of ions on embryo viability. This study was conducted to assess the effect of salinity on germination of chickpea (Cicer arietinum L. in the laboratory of Mekelle University by using NaCl and Na2So4 to simulate salinity and tape water as control group. The seeds of chickpea (Cicer arietinum landraces were collected from Hagereselam and Samre. Then 10 seeds of chickpea from both sites were treated in each salt concentration in 3 replications designed by using complete random block design. The result of the experiment showed that the concentrations of salt have a negative impact on the germination and growth of chickpea, as a result when the concentration of salt increases, the germination, water uptake and length of root and shoot decreases. Furthermore we found that different salinity simulated having different impacts on germination. Our result clearly indicated that NaCl highly affects germination and growth of chickpea than Na2SO4. Meanwhile, the effect of salinity for both land race have significance difference in parameters of water up take, % of germination, length of root and shoot (t-test n = 25 p<0.05. Our result further indicated that there is a difference in sanity tolerance level between the 2 land races of chickpea.

  12. Biofortification of iron in chickpea by plant growth promoting rhizobacteria

    International Nuclear Information System (INIS)

    Iron deficiency is a major nutritional disorder being responsible to affect millions of people around the globe. Its malnutrition may be reduced through biofortification: a process to produce micronutrient enriched staple food. Plant growth promoting rhizobacteria (PGPR) can fortify iron content within edible plant tissues by enhancing its availability through various mechanisms. In a pot study, five bacterial isolates (S1, S2, S3, S4 and S5) were tested for improving plant growth and bioavailable iron (Fe) content in chickpea where Fe was applied in the form of iron sulphate solution. Results showed that inoculation with PGPR significantly enhanced the plant height, root length, root fresh and dry weights, shoot fresh and dry weights and Fe content compared to un-inoculated control plants. Application of FeSO/sub 4/ significantly improved the Fe content upto 100 and 173% in grain and shoot respectively, as compared to control. Application of PGPR along with iron showed 81 and 75% increase in grain and shoot iron contents, respectively, over control. These results suggested that PGPR can help plants to uptake extra Fe from soil, if soil is supplemented with additional Fe. These findings advocate that microbial assisted biofortification in grain can alleviate micronutrient deficiency in humans especially in resource limited countries. (author)

  13. Varietal differences in photosynthesis and productivity of chickpea

    International Nuclear Information System (INIS)

    In 12 genotypes of chickpea (Cicer arietinum Linn.) there was considerable variability in the activity of RuDPC, and PEPC, and in the net photosynthetic rate, photorespiration, leaf area index (LAI), biological yield, sink components and seed yield, with little diversity in CO2-compensation point. The net photosynthetic rate did not have significant correlations with RuDPC or PEPC activity and photorespiration, but it was correlated positively with PEPC activity at flowering and negatively with photorespiration at flower-bud initiation. Assimilate production seemed to determine seed yield, as high photosynthetic rate at the stage of flower-bud initiation increased pods/plant. The net photosynthesis during grain development and the LAI at the full-bloom stage determined the differences in biological yield, which was positively correlated with 1,000 seed weight. Seed number/pod, however, was not related to assimilate production. 14CO2 was used in the study to estimate the rate of photosynthesis. (auth.)

    Chickpea (Cicer arietinum) is among the founder crops domesticated in the Fertile Crescent. One of two major forms of chickpea, the so-called kabuli type, has white flowers and light-colored seed coats, properties not known to exist in the wild progenitor. The origin of the kabuli form has been enigmatic. We genotyped a collection of wild and cultivated chickpea genotypes with 538 single nucleotide polymorphisms (SNPs) and examined patterns of molecular diversity relative to geographical sources and market types. In addition, we examined sequence and expression variation in candidate anthocyanin biosynthetic pathway genes. A reduction in genetic diversity and extensive genetic admixture distinguish cultivated chickpea from its wild progenitor species. Among germplasm, the kabuli form is polyphyletic. We identified a basic helix-loop-helix (bHLH) transcription factor at chickpea's B locus that conditions flower and seed colors, orthologous to Mendel's A gene of garden pea, whose loss of function is associated invariantly with the kabuli type of chickpea. From the polyphyletic distribution of the kabuli form in germplasm, an absence of nested variation within the bHLH gene and invariant association of loss of function of bHLH among the kabuli type, we conclude that the kabuli form arose multiple times during the phase of phenotypic diversification after initial domestication of cultivated chickpea.

    Steroidogenic acute regulatory related transfer (StART) proteins that are involved in transport of lipid molecules, play a myriad of functions in insects, mammals and plants. These proteins consist of a modular START domain of approximately 200 amino acids which binds and transfers the lipids. In the present study we have performed a genome-wide search for all START domain proteins in chickpea. The search identified 36 chickpea genes belonging to the START domain family. Through a phylogenetic tree reconstructed with Arabidopsis, rice, chickpea, and soybean START proteins, we were able to identify four transmembrane START (TM-START) proteins in chickpea. These four proteins are homologous to the highly conserved mammalian phosphatidylcholine transfer proteins. Multiple sequence alignment of all the transmembrane containing START proteins from Arabidopsis, rice, chickpea, and soybean revealed that the amino acid residues to which phosphatidylcholine binds in mammals, is also conserved in all these plant species, implying an important functional role and a very similar mode of action of all these proteins across dicots and monocots. This study characterizes a few of the not so well studied transmembrane START superfamily genes that may be involved in stress signaling. Expression analysis in various tissues showed that these genes are predominantly expressed in flowers and roots of chickpea. Three of the chickpea TM-START genes showed induced expression in response to drought, salt, wound and heat stress, suggesting their role in stress response. PMID:26445326

    The total saponin content and its in vitro bioaccessibilities in Tribulus terrestris and chickpea were determined by a static in vitro digestion method (COST FA1005 Action INFOGEST). Also, in vitro inhibitory effects of the chosen food samples on lipid and starch digestive enzymes were determined by evaluating the lipase, α-amylase and α-glucosidase activities. The tested T. terrestris and chickpea showed inhibitory activity against α-glucosidase (IC50 6967 ± 343 and 2885 ± 85.4 μg/ml, respectively) and α-amylase (IC50 343 ± 26.2 and 167 ± 6.12 μg/ml, respectively). The inhibitory activities of T. terrestris and chickpea against lipase were 15.3 ± 2.03 and 9.74 ± 1.09 μg/ml, respectively. The present study provides the first evidence that these food samples (T. terrestris, chickpea) are potent inhibitors of key enzymes in digestion of carbohydrates and lipids in vitro. PMID:27006227

    Landraces of chickpea (Cicer arietinum L.) in Iran have not been adequately characterized for their agronomic and morphological traits. Such characterization would be helpful in the development of improved cultivars, so in this study 362 chickpea accessions, collected from the major chickpea growing areas of Iran, were evaluated to determine their phenotypic diversity. High coefficients of variation (CVs)were recorded in pods/branch, seeds/pod, yield/plant, seeds/plant, pods/plant and branches/plant. Using principal component (PC) analysis, the first four PCs with eigenvalues more than 1 contributed 84.10% of the variability among accessions, whereas PC5 to PC10 were less than unity. PC1 was positively related to days to first maturity, days to 50% flowering and days to 50% maturity. The characters with the greatest weight on PC2 were seeds/plant and yield/plant, whereas PC3 was mainly related to pods/plant, seeds/pod and 100-seed weight, and PC4 was positively related to pods/branch and negatively to branches/plant. The germplasm was grouped into four clusters using cluster analysis. Each cluster had some specific characteristics of its own and the cluster I was clearly separated from clusters Ⅱ, Ⅲ and Ⅳ. These accessions are an important resource for the establishment of a core collection of chickpeas in the world.

    Two plant growth promoting rhizobacteria (PGPR) Pseudomonas putida NBRIRA and Bacillus amyloliquefaciens NBRISN13 with ability to tolerate abiotic stress along with multiple PGP traits like ACC deaminase activity, minerals solubilisation, hormones production, biofilm formation, siderophore activity were evaluated for their synergistic effect to ameliorate drought stress in chickpea. Earlier we have reported both the strains individually for their PGP attributes and stress amelioration in host plants. The present study explains in detail the possibilities and benefits of utilizing these 2 PGPR in consortium for improving the chickpea growth under control and drought stressed condition. In vitro results clearly demonstrate that both the PGPR strains are compatible to each other and their synergistic growth enhances the PGP attributes. Greenhouse experiments were conducted to evaluate the effect of inoculation of both strains individually and consortia in drought tolerant and sensitive cultivars (BG362 and P1003). The growth parameters were observed significantly higher in consortium as compared to individual PGPR. Colonization of both PGPR in chickpea rhizosphere has been visualized by using gfp labeling. Apart from growth parameters, defense enzymes, soil enzymes and microbial diversity were significantly modulated in individually PGPR and in consortia inoculated plants. Negative effects of drought stress has been ameliorated and apparently seen by higher biomass and reversal of stress indicators in chickpea cultivars treated with PGPR individually or in consortia. Findings from the present study demonstrate that synergistic application has better potential to improve plant growth promotion under drought stress conditions. PMID:26362119

  5. Nutritional and chemical alteration of raw, irradiated and cooked chickpea (Cicer arietinum L.)

    International Nuclear Information System (INIS)

    The work objective was analyzing the centesimal and mineral composition to verifying the alterations on the nutritional characteristics caused by the cooking process. Also were carried out analysis of the iron availability in vitro, protein digestibility in vitro and the profile of amino acids in the raw and cooked in the control and irradiated seeds (doses of 2 kGy, 4 kGy, 6 kGy, 8 kGy and 10 kGy). The results of the mineral analysis showed that only phosphorus decrease with cooking process and it decreased ash and carbohydrates available. In the control and in the doses of 4 kGy and 6 kGy the cooking has not influenced the digestibility of the protein, but the treatments that received radiation doses of 2 kGy, 8 kGy and 10 kGy were influenced. The cooked chickpea has shown better digestibility in higher doses of radiation although the treatments have shown low digestibility. The raw chickpea presented a better dialysis of iron in the control and in the doses 2 kGy and 4 kGy and the cooked chickpea presented improvement according to the increase of radiation doses. In relation to the essential amino acids, the chickpea has presented an adequate nutritional value, except for the methionine. (author)

  6. Biological control of chickpea wilt caused by fusarium oxysporum f.sp.ciceris

    International Nuclear Information System (INIS)

    This study was conducted in an attempt to control chickpea (Cicer arietinum L.) wilt, caused by fusarium oxysporum f.sp. ciceris, using antagonistic properties of soil microorganisms. It also aimed at avoiding problems resulting from the use of chemical fungicides. A trichoderma sp. was isolated from the rhizosphere of a resistant chickpea variety (ICCV-2) and a bacillus sp. from the rhizosphere and rhizoplane of the same variety. Both microorganisms proved to be effective in controlling the disease. In addition, trichoderma harzianum, which was obtained from Giza Research Station in Egypt, was also antagonistic to fusarium oxysporum f. sp. ciceris Wilt incidence was significantly reduced when chickpea was grown in posts containing soil mixed with any of the three antagonists or when chickpea seeds were initially treated with the seed-dressing fungicide vincit at 2 ml/kg seeds. Trichoderma harzianum proved to be the best bioagent as it gave the lowest disease incidence. In the field, the two trichoderma spp. were as effective as vincit in causing reduction in the wilt incidence. At the higher concentration of 140 g/m''2, the two antagonists were effective throughout the growth period, but they were less effective at the lower concentration of 70 g/m''2 particularly at the seedling stage.(Author)

  10. The chickpea, summer cropping, and a new model for pulse domestication in the ancient near east.

    The widely accepted models describing the emergence of domesticated grain crops from their wild type ancestors are mostly based upon selection (conscious or unconscious) of major features related either to seed dispersal (nonbrittle ear, indehiscent pod) or free germination (nondormant seeds, soft seed coat). Based on the breeding systems (self-pollination) and dominance relations between the allelomorphs of seed dispersal mode and seed dormancy, it was postulated that establishment of the domesticated forms and replacement of the wild ancestral populations occurred in the Near East within a relatively short time. Chickpea (Cicer arietinum L.), however, appears as an exception among all other "founder crops" of Old World agriculture because of its ancient conversion into a summer crop. The chickpea is also exceptional because its major domestication trait appears to be vernalization insensitivity rather than pod indehiscence or free germination. Moreover, the genetic basis of vernalization response in wild chickpea (Cicer reticulatum Ladiz.) is polygenic, suggesting that a long domestication process was imperative due to the elusive phenotype of vernalization nonresponsiveness. There is also a gap in chickpea remains in the archaeological record between the Late Prepottery Neolithic and the Early Bronze Age. Contrary to the common view that Levantine summer cropping was introduced relatively late (Early Bronze Age), we argue for an earlier (Neolithic) Levantine origin of summer cropping because chickpea, when grown as a common winter crop, was vulnerable to the devastating pathogen Didymella rabiei, the causal agent of Ascochyta blight. The ancient (Neolithic) conversion of chickpea into a summer crop required seasonal differentiation of agronomic operation from the early phases of the Neolithic revolution. This topic is difficult to deal with, as direct data on seasonality in prehistoric Old World field crop husbandry are practically nonexistent. Consequently

    The main objective of the present study was to isolate and characterize actinomycetes for their plant growth-promotion in chickpea. A total of 89 actinomycetes were screened for their antagonism against fungal pathogens of chickpea by dual culture and metabolite production assays. Four most promising actinomycetes were evaluated for their physiological and plant growth-promotion properties under in vitro and in vivo conditions. All the isolates exhibited good growth at temperatures from 20°C to 40°C, pH range of 7-11 and NaCl concentrations up to 8%. These were also found highly tolerant to Bavistin, slightly tolerant to Thiram and Captan (except VAI-7 and VAI-40) but susceptible to Benlate and Ridomil at field application levels and were found to produce siderophore, cellulase, lipase, protease, chitinase (except VAI-40), hydrocyanic acid (except VAI-7 and VAI-40), indole acetic acid and β-1,3-glucanase. When the four actinomycetes were evaluated for their plant growth-promotion properties under field conditions on chickpea, all exhibited increase in nodule number, shoot weight and yield. The actinomycetes treated plots enhanced total N, available P and organic C over the un-inoculated control. The scanning electron microscope studies exhibited extensive colonization by actinomycetes on the root surface of chickpea. The expression profiles for indole acetic acid, siderophore and β-1,3-glucanase genes exhibited up-regulation for all three traits and in all four isolates. The actinomycetes were identified as Streptomyces but different species in the 16S rDNA analysis. It was concluded that the selected actinomycetes have good plant growth-promotion and biocontrol potentials on chickpea. PMID:26887230

    Full Text Available Abstract Background Cultivated chickpea (Cicer arietinum has a narrow genetic base making it difficult for breeders to produce new elite cultivars with durable resistance to major biotic and abiotic stresses. As an alternative to genome mapping, microarrays have recently been applied in crop species to identify and assess the function of putative genes thought to be involved in plant abiotic stress and defence responses. In the present study, a cDNA microarray approach was taken in order to determine if the transcription of genes, from a set of previously identified putative stress-responsive genes from chickpea and its close relative Lathyrus sativus, were altered in chickpea by the three abiotic stresses; drought, cold and high-salinity. For this, chickpea genotypes known to be tolerant and susceptible to each abiotic stress were challenged and gene expression in the leaf, root and/or flower tissues was studied. The transcripts that were differentially expressed among stressed and unstressed plants in response to the particular stress were analysed in the context of tolerant/susceptible genotypes. Results The transcriptional change of more than two fold was observed for 109, 210 and 386 genes after drought, cold and high-salinity treatments, respectively. Among these, two, 15 and 30 genes were consensually differentially expressed (DE between tolerant and susceptible genotypes studied for drought, cold and high-salinity, respectively. The genes that were DE in tolerant and susceptible genotypes under abiotic stresses code for various functional and regulatory proteins. Significant differences in stress responses were observed within and between tolerant and susceptible genotypes highlighting the multiple gene control and complexity of abiotic stress response mechanism in chickpea. Conclusion The annotation of these genes suggests that they may have a role in abiotic stress response and are potential candidates for tolerance/susceptibility.

    The present study exploited integrated genomics-assisted breeding strategy for genetic dissection of complex branch number quantitative trait in chickpea. Candidate gene-based association analysis in a branch number association panel was performed by utilizing the genotyping data of 401 SNP allelic variants mined from 27 known cloned branch number gene orthologs of chickpea. The genome-wide association study (GWAS) integrating both genome-wide GBS- (4556 SNPs) and candidate gene-based genotyping information of 4957 SNPs in a structured population of 60 sequenced desi and kabuli accessions (with 350-400kb LD decay), detected 11 significant genomic loci (genes) associated (41% combined PVE) with branch number in chickpea. Of these, seven branch number-associated genes were further validated successfully in two inter (ICC 4958×ICC 17160)- and intra (ICC 12299×ICC 8261)-specific mapping populations. The axillary meristem and shoot apical meristem-specific expression, including differential up- and down-regulation (4-5 fold) of the validated seven branch number-associated genes especially in high branch number as compared to the low branch number-containing parental accessions and homozygous individuals of two aforesaid mapping populations was apparent. Collectively, this combinatorial genomic approach delineated diverse naturally occurring novel functional SNP allelic variants in seven potential known/candidate genes [PIN1 (PIN-FORMED protein 1), TB1 (teosinte branched 1), BA1/LAX1 (BARREN STALK1/LIKE AUXIN1), GRAS8 (gibberellic acid insensitive/GAI, Repressor of ga13/RGA and Scarecrow8/SCR8), ERF (ethylene-responsive element-binding factor), MAX2 (more axillary growth 2) and lipase] governing chickpea branch number. The useful information generated from this study have potential to expedite marker-assisted genetic enhancement by developing high-yielding cultivars with more number of productive (pods and seeds) branches in chickpea.

  16. Sources of resistance in chickpea (cicer arietinum l.) land races against ascochyta rabiei causal agent of ascochyta blight disease

    International Nuclear Information System (INIS)

    Ascochyta blight disease, caused by the fungus Ascochyta rabiei, is a major yield limiting factor of chickpea in Turkey and around the world. This study was conducted to identify sources of genetic resistance against chickpea blight caused by Ascochyta rabiei. For this purpose, 68 chickpea land races of different origins were evaluated in both field and growth chamber conditions during 2008-2009 growing seassons. Two standard cultivars were used as a reference, Inci (resistant) and Canitez (susceptible). Disease severity scoring was conducted on a 1-9 rating scale 21 days after inoculation in growth chamber test and at flowering and pot filling stages in field tests. Analysis of variance (ANOVA) test showed a significant difference among the chickpea landraces in ascochyta blight resistance at p<0.05. None of the chickpea land races was highly resistant to the pathogen in growth chamber and field conditions. Only two landraces (10A and 28B) were moderately resistant to the disease. Some of the landraces resulted in a particular plant to exhibit no disease symptoms, indicating that the variation within chickpea land races was high. Therefore, seeds of this plant were harvested separately and preserved for further evaluations. (author)

    In vitro starch digestibility, expected glycemic index (eGI), and thermal and pasting properties of flours from pea, lentil and chickpea grown in Canada under identical environmental conditions were investigated. The protein content and gelatinization transition temperatures of lentil flour were higher than those of pea and chickpea flours. Chickpea flour showed a lower amylose content (10.8-13.5%) but higher free lipid content (6.5-7.1%) and amylose-lipid complex melting enthalpy (0.7-0.8J/g). Significant differences among cultivars within the same species were observed with respect to swelling power, gelatinization properties, pasting properties and in vitro starch digestibility, especially chickpea flour from desi (Myles) and kabuli type (FLIP 97-101C and 97-Indian2-11). Lentil flour was hydrolyzed more slowly and to a lesser extent than pea and chickpea flours. The amount of slowly digestible starch (SDS) in chickpea flour was the highest among the pulse flours, but the resistant starch (RS) content was the lowest. The eGI of lentil flour was the lowest among the pulse flours. PMID:26047429

    Drought and salinity are the major factors that limit chickpea production worldwide. We performed whole transcriptome analyses of chickpea genotypes to investigate the molecular basis of drought and salinity stress response/adaptation. Phenotypic analyses confirmed the contrasting responses of the chickpea genotypes to drought or salinity stress. RNA-seq of the roots of drought and salinity related genotypes was carried out under control and stress conditions at vegetative and/or reproductive stages. Comparative analysis of the transcriptomes revealed divergent gene expression in the chickpea genotypes at different developmental stages. We identified a total of 4954 and 5545 genes exclusively regulated in drought-tolerant and salinity-tolerant genotypes, respectively. A significant fraction (~47%) of the transcription factor encoding genes showed differential expression under stress. The key enzymes involved in metabolic pathways, such as carbohydrate metabolism, photosynthesis, lipid metabolism, generation of precursor metabolites/energy, protein modification, redox homeostasis and cell wall component biogenesis, were affected by drought and/or salinity stresses. Interestingly, transcript isoforms showed expression specificity across the chickpea genotypes and/or developmental stages as illustrated by the AP2-EREBP family members. Our findings provide insights into the transcriptome dynamics and components of regulatory network associated with drought and salinity stress responses in chickpea. PMID:26759178

  19. Control of root rot of chickpea caused by Sclerotium rolfsii by different agents and gamma radiation

    International Nuclear Information System (INIS)

    Sclerotium rolfsii causes root rot disease in several crops including chickpea that result in low yield. Artificial infection of chickpea seedlings by S. rolfsii in vitro demonstrated that different tissues of the plant completely disintegrated by fungal infection. In vitro and green house pot experiments demonstrated that inducers in combination with fungicides, oils and bio agents resulted in about 80 % suppression of root rot disease. Treatments have no phyto toxic effect on chickpea seedlings at low doses. Gliocladium virens and Gliocladium deliquescens were effective as biocontrol agents against Sclerotium rolfsii. The percent of survival plants, fresh weight, dry weight and plant height of chickpea plants increased with different treatments with inducers compared with the control. Chlorophyll a, b, and total chlorophyll amounts increased to the maximum values. The activity of two plant enzymes, peroxidase and polyphenol oxidase increased. In this study, gamma irradiation of chickpea seeds at doses 5, 10, 15, 20, 25 and 30 Gy have negative effect on survival, plant height, fresh weight and dry weight of chickpea. The effect of gamma irradiation at doses 0.25, 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 kGy on the antagonistic effect of Gliocladium virens and Gliocladium deliquescens against S. rolfsii were investigated. The results revealed that gamma irradiation increase the antagonistic effect of Gliocladium virens and Gliocladium deliquescens against S. rolfsii . Effect of gamma irradiation at doses of 0, 0.25, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 and 5 kGy on the mycelial growth and pathogenicity of S. rolfsii were investigated. The results revealed that gamma irradiation at doses 0.25 up to 3.0 kGy increase the pathogenicity of S. rolfsii but gamma irradiation at dose 5.0 kGy completely inhibited the growth of S. rolfsii. Extracellular polygalacturonase was characterized and purified by precipitation with 70 % ammonium sulfate, dialysis and gel filtration through Sephadex 75

  20. Biological N2 Fixation by Chickpea in inter cropping System on Sand Soil

    International Nuclear Information System (INIS)

    A field experiment was carried out at the plant Nutrition and Fertilization Unit, Soils and Water Research Department, Nuclear Research Center, Atomic Energy Authority, Inshas, Egypt on wheat and chickpea inter cropping. The benefits of N2 fixation by legumes to cereals growing in inter crops or to grasses growing in mixed swards are high clear. in cases the benefit to the N status of cereals has bee seen when they are inter cropped with legumes , where benefit is found ,it is mainly due to sparing of soil N rather than direct transfer from the legume. inter cropped wheat has a high grains yield as compared to those recorded under sole crop. The application of inter cropping system induced an increase of wheat grain yield against the sole system. regardless the cultivation system, the over all means of fertilizer rates indicated (50% MF + 50% OM) treatment was superiority (100% OM) and (75% MF + 25% OM) or those recorded with either un fertilizer when wheat grain yield considered. Comparison heed between organic sources reflected the superiority of under sole cultivation, while chickpea straw was the best under inter cropping. Inter cropped has a high grain N uptake compared to soil system. While totally organic materials had accumulates more N in grain than those of underrated treated control. In the same time, the overall mean indicated the superiority of compost treatment combined with 50% mineral fertilizer under inter cropping system over those of either only organic materials treatment or those combined with 75% mineral fertilizer. Plants treated of chickpea straw and compost, achieved the best value of straw weight. Among the organic manure treatments, chickpea straw and compost seem to be the best ones. Nitrogen derived from air (% Ndfa) shoots and seeds of chickpea plant: In case of cow manure and maize stalk, the best value of nitrogen derived from air was detected followed by compost, while the lowest value was recorded with wheat straw.

    The degradation of 14C-lindane (γ-1,2,3,4,5,6 - hexachlorocyclohexane) was investigated under laboratory conditions. Chickpea plants and soil were treated with 14C-lindane. The results indicated a decrease of lindane on the plant surface from 36.6% to 6.5% and a corresponding increase in extractable residues from within the plant from 12.5% to 34.5% during the 60 days of the trial. In the soil, extractable residues decreased from 47.4% to 31.2%. Bound residues in both plant and soil remained low throughout the trial. After 60 days, the chickpea plants took up 16.4% of the lindane applied to the soil. (author). 2 refs, 7 figs

  2. The improvement of TAEK-SAGEL chickpea (Cicer arietinum L.) mutant variety in Turkey

    International Nuclear Information System (INIS)

    Chickpea is an important food legume in Turkey. Turkey is one of the most important gene centers in the world for legumes. The most widely known characteristic of chickpea is that it is an important vegetable protein source used in human and animal nutrition. However, the dry grains of chickpea, has 2-3 times more protein than our traditional food of wheat. In addition, because of it's high carbohydrate content, it is also energy source. It is very rich some vitamin and minerals basis. In the plant breeding, mutation induction has become an effective way of supplementing existing germplasm and improving cultivars. Many successful examples of mutation induction have proved that mutation breeding is an effective and important approach to food legume improvement. The induced mutation technique in chickpea has proved successful and good results have been attained. Realizing the potential of induced mutations, a mutation breeding programme was initiated at the Nuclear Agriculture Section of the Saraykoey Nuclear Research and Training Center in 1994. The purpose of the study was to obtain high yielding chickpea varieties with large seeds, good cooking quality and high protein content. Seeds of the Ak-71114 and Akcin chickpea varieties were irradiated with 0 (control), 50, 100, 150, 200, 250, 300, 350 ve 400 Gy of gamma rays by using60Cosource. One thousand seeds for per treatment were sown in the field for the M1. At maturity, 3500 single plants were harvested and 20 seeds taken from each M1 plant and planted in the following season. During plant growth, mutants of the desired traits (earliness, yield per plant, first pot height and Ascochyta blight (Ascochyta rabie) resistance) were identified an isolated. 2520 desirable M2 mutants were selected and grown in progeny rows as the M3 generation. The protein content was analyzed for the M3-M4 seeds. In M5 generation, preliminary yield trials had been conducted and based on field observations, quality criteria (grain size

    Full Text Available The influence of chickpea (Cicer arietinum planting date on seasonal epidemics of Ascochyta blight caused by Ascochyta rabiei (Pass. Labrousse and on grain yield was evaluated during the 1997 and 1998 cropping seasons. Two chickpea cultivar (Ghab 1 and Ghab 3 and 2 breeding lines (FLIP 90-96 and F 88-85 were used in the field trials at 3 different locations representing the different agro ecological zones in which winter chickpea is grown in Syria and in most of the Mediterranean countries. Four field plantings were made at 14-day intervals from mid November to mid March. All plots were initially inoculated with infected debris and disease development followed natural prevailing environmental conditions. Ascochyta blight disease severity ratings were taken at early flowering and again at podding and grain yield for each plot was measured at harvest. There was a significant (p<0.05 increase in disease severity between the first and third planting in all the entries at all the locations and for both years. The difference in disease severity resulted in significant yield differences but not in differences in seed quality. Under Syrian and Mediterranean conditions, an increase in Ascochyta blight severity can be expected with early planting of chickpea before January and this can result in a corresponding big loss in crop yield. The loss in yield from disease through early plantings however, is more than compensated for, by the reduction in yield due to other environmental parameters in late spring planting, if moderate resistant cultivars are planted.

    2015-11-01

    Full Text Available Jasmonates (JA are well-known phytohormones which play important roles in plant development and defence against pathogens. Jasmonate ZIM domain (JAZ proteins are plant-specific proteins and act as transcriptional repressors of JA-responsive genes. JA regulates both biotic and abiotic stress responses in plants; however, its role in nutrient deficiency responses is very elusive. Although, JA is well-known for root growth inhibition, little is known about behaviour of JAZ genes in response to nutrient deficiencies, under which root architectural alteration is an important adaptation. Using protein sequence homology and a conserved-domains approach, here we identify ten novel JAZ genes from the recently sequenced Chickpea genome, which is one of the most nutrient efficient crops. Both rice and chickpea JAZ genes express in tissue- and stimuli-specific manners. Many of which are preferentially expressed in root. Our analysis further showed differential expression of JAZ genes under macro (NPK and micronutrients (Zn, Fe deficiency in rice and chickpea roots. While both rice and chickpea JAZ genes showed a certain level of specificity towards type of nutrient deficiency, generally majority of them showed induction under K deficiency. Generally, JAZ genes showed an induction at early stages of stress and expression declined at later stages of macro-nutrient deficiency. Our results suggest that JAZ genes might play a role in early nutrient deficiency response both in monocot and dicot roots, and information generated here can be further used for understanding the possible roles of JA in root architectural alterations for nutrient deficiency adaptations

  10. Evaluation of chickpea and groundnut for N2 fixation and yield in Bangladesh

    International Nuclear Information System (INIS)

    Field experiments on chickpea and groundnut were variously carried out at four locations in Bangladesh. Generally consistent trends were obtained in terms of positive effects of inoculation with rhizobia, and genotypic diversity for components of N2 fixation and yield. Inoculation of groundnut increased average nodule number by 77% at Rajshahi, 99% at Mymensingh and 148% at Jamalput. The increases in nodule dry weight, plant dry weight, pod and stover yields due to inoculation ranged from 93 to 146%, 55 to 77%, 43 to 50% and 29 to 80%, respectively. At all three locations, significant differences were found amongst the genotypes for nodulation, dry matter production and yield. Mutant genotype 62-30 was superior for most components, and statistically better than the present variety Dacca-1 for all characteristics investigated. Inoculant application to chickpea resulted in at least a doubling of nodule number at Ishurdi and Mymensingh; on average, there was a three-fold increase in nodule mass as a result of inoculation. Seed-yield increases due to inoculation ranged from 24 to 50%. Inoculated cv. G-97 recorded a seed yield of about 1.5 t/ha at Ishurdi, 47% higher than that produced by Nabin, a variety widely cultivated in Bangladesh. Total-N yield and the amount of N fixed by G-97 with inoculant were also higher than for Hyprosola, which is known for high yield and protein content. In a screening trial at Mymensingh the commercial chickpea Nabin and Hyprosola were consistently inferior to advanced lines produced by mutation breeding. Of 12 mutant groundnut genotypes tested, D1-15KR/62-30 maintained superiority for almost all components. Most of the mutants performed better than the commercial variety Dacca-1. The data show the potential for increasing chickpea and groundnut yields in Bangladesh by improving N2 fixation via selection of superior genotype in conjunction with compatible rhizobia

    Chickpea (Cicer arietinum L.) is the second most important cool season food legume cultivated in arid and semiarid regions of the world. The objective of the present study was to study variation for protein content in chickpea germplasm, and to find markers associated with it. A set of 187 genotypes comprising both international and exotic collections, and representing both desi and kabuli types with protein content ranging from 13.25% to 26.77% was used. Twenty-three SSR markers representing all eight linkage groups (LG) amplifying 153 loci were used for the analysis. Population structure analysis identified three subpopulations, and corresponding $Q$ values of principal components were used to take care of population structure in the analysis which was performed using general linear and mixed linear models. Marker-trait association (MTA) analysis identified nine significant associations representing four QTLs in the entire population. Subpopulation analyses identified ten significant MTAs representing five QTLs, four of which were common with that of the entire population. Two most significant QTLs linked with markers TR26.205 and CaM1068.195 were present on LG3 and LG5. Gene ontology search identified 29 candidate genes in the region of significant MTAs on LG3. The present study will be helpful in concentrating on LG3 and LG5 for identification of closely linked markers for protein content in chickpea and for their use in molecular breeding programme for nutritional quality improvement.

    International Nuclear Information System (INIS)

    The phyto-accumulation efficacy of selenium (Se) from soil by chickpea plant is reported. Chickpea plants were grown in soil having different concentrations (1-4 mg kg-1) of Se. Samples of soil and different parts of chickpea plants in Se rich soil were analyzed for determination of Se concentrations by instrumental neutron activation analysis (INAA). Samples were irradiated in self-serve facility of CIRUS reactor, BARC, Mumbai at a neutron flux of the order of 1013 cm-2 s-1. The gamma activity at 264.7 keV of 75Se (119.8 d) was measured using a 45% relative efficiency HPGe detector coupled to MCA. Dependence of Se distribution in soil and plants on its spiking concentration was evaluated in this work. The Se concentrations determined in plant parts grown in control soil and in soil spiked with Se (4 mg kg-1) are in the range of 0.6-0.8 and 65-68 mg kg-1 respectively. (author)

    Full Text Available Although many consumers know that pulses are nutritious, long preparation times are frequently a barrier to consumption of lentils, dried peas and chickpeas. Therefore, a product has been developed which can be used as an ingredient in a wide variety of dishes without presoaking or precooking. Dried green peas, chickpeas or lentils were soaked, cooked, homogenized and spray-dried. Proximate analyses were conducted on the pulse powders and compared to an instant mashed potato product. Because the health benefits of pulses may be due in part to their carbohydrate content, a detailed carbohydrate analysis was carried out on the pulse powders. Pulse powders were higher in protein and total dietary fibre and lower in starch than potato flakes. After processing, the pulse powders maintained appreciable amounts of resistant starch (4.4%–5.2%. Total dietary fibre was higher in chickpeas and peas (26.2% and 27.1% respectively than lentils (21.9%, whereas lentils had the highest protein content (22.7%. Pulse carbohydrates were rich in glucose, arabinose, galactose and uronic acids. Stachyose, a fermentable fibre, was the most abundant oligosaccharide, making up 1.5%–2.4% of the dried pulse powders. Spray-drying of cooked, homogenized pulses produces an easy to use ingredient with strong nutritional profile.

    Sulphur fertilization (5, 10, 15, 20, 25, 30 mg/kg soil) of the chickpea as ground elemental sulphur in the presence of uniform dressing of nitrogen, phosphorus (P/sub 2/O/sub 5/) and Potash (K /sub 2/O) each applied at the rate of 5, 40, 20 mg/kg soil, respectively improved significantly the modulation response (number and weight of nodules/plant), and increased significantly the dry matter yield of pods of the crop by 23.0 to 59.0 percent, of shoots by 22 to 61.0 percent and of roots by 13.0 to 22.0 percent. Sulphur application also improved significantly the N concentration and uptake by pods, shoots and roots of chickpea. The increase in N uptake by pods was in the range of 33 to 92 percent, by shoots in the range of 65 to 115 percent and by the roots in the range of 52 to 65.0 percent. Sulphur at the rate of 10 mg/kg soil was the optimum dose in the present experiment, which increased the dry matter yield of roots, shoots and pods by 22.0 to 59.0 percent and N uptake by roots, shoots and pods of chickpea by 65.0 to 115.0 percent.

    Full Text Available The chickpea is an important field crop for low quality fields and drought-enduring, in Isparta ecology, as a sowing duty covers a large area. This research has been conducted in order to determine the most suitable chickpea line and varieties in the grain-chickpea sowing duty system of the Isparta city ecological conditions. Eleven cultivars and lines grown in Turkey were used in this two-year long study (between the years 1996 and 1997, which involved a randomize block experimental design with four replications. Data were analyzed by multivariate statistical methods. According to the two-year results, the differences between the lines and cultivars were found to be important in all components observed. The annual differences proved significant for all components, except the number of pods per plant and the height of the first pod from the ground. Anthracnose (Ascochyta rabiei pass. Lab. was not found in any cultivar and line in natural conditions, in none of the tow years. One principal component (PC1 was found by factorial analyses. The eleven examined cultivars were separated in two main groups and three subclusters by cluster analyses.

    Chickpea is a food legume which is alleged to be a preferred source of protein next only to milk. Germplasm of cultivated chickpea available is deficient in desired genetic variation. Genetic manipulations therefore, necessitate the genetic exploitation of its related annual and wild species. 42 RAPD and 41 ISSR markers were employed to ascertain polymorphism across 20 genotypes which were collected from 10 different geographical areas of the world. RAPD marker detected 51% genetic polymorphisms while ISSR marker detected 54 %. With an average of 6.5 each RAPD primer amplified 5—8 bands. Similarly with an average of 7.9 each ISSR primer amplified 4—12 bands. The cluster dendrogram demonstrated a similarity coefficient range from 0.80 to 0.92 due to RAPD markers, whereas with ISSR primers the cluster dendrogram showed similarity coefficient of 0.60 to 1.00. Accessions from same geographical area seem to be genetically similar than those from geographically distant and isolated ones. When however compared, interestingly the ISSR dendrogram showed more correlation with pedigree data than the RAPD dendrogram. The variability index worked out in the present study ranges from 0.79 to 0.96. Since the ultimate reason for such studies is selection of diverse genetic accessions for their recommendation to breeding programmers, the accessions like ICC6263, ICC6306 and ICC17160 can be recommended as parents. Further breeding programmes can therefore be planned to procure additional variation complexes in chickpea genetic stocks. PMID:26516116

    Full Text Available Fusarium wilt caused by Fusarium oxysporum f.sp. ciceri (Foc is a constant threat to chickpea productivity in several parts of the world. Understanding the molecular basis of chickpea-Foc interaction is necessary to improve chickpea resistance to Foc and thereby the productivity of chickpea. We transformed Foc race 2 using green fluorescent protein (GFP gene and used it to characterize pathogen progression and colonization in wilt-susceptible (JG62 and wilt-resistant (Digvijay chickpea cultivars using confocal microscopy. We also employed quantitative PCR (qPCR to estimate the pathogen load and progression across various tissues of both the chickpea cultivars during the course of the disease. Additionally, the expression of several candidate pathogen virulence genes was analyzed using quantitative reverse transcriptase PCR (qRT-PCR, which showed their characteristic expression in wilt-susceptible and resistant chickpea cultivars. Our results suggest that the pathogen colonizes the susceptible cultivar defeating its defense; however, albeit its entry in the resistant plant, further proliferation is severely restricted providing an evidence of efficient defense mechanism in the resistant chickpea cultivar.

    Trichoderma reesei is an industrially important fungi which also imparts stress tolerance and plant growth promotion in various crops. Arsenic (As) contamination of field soils is one of the challenging problems in agriculture, posing potential threats for both human health and the environment. Plants in association with microbes are a liable method to improve metal tolerance and enhance crop productivity. Chickpea (Cicer arietinum L.), is an important grain legume providing cheap source of protein in semi-arid regions including As affected areas. In this study we report the role of T. reesei NBRI 0716 (NBRI 0716) in supporting chickpea growth and improving soil quality in As simulated conditions. NBRI 0716 modulated the As speciation and its availability to improve grain yield and quality (amino acids and mineral content) in chickpea (C. arietinum L.) plants grown in As spiked soil (100 mg As kg(-1) soil). Arsenic accumulation and speciation results indicate that arsenate [As(V)] was the dominant species in chickpea seeds and rhizosphere soil. The Trichoderma reduced total grain inorganic As (Asi) by 66% and enhanced dimethylarsonic acid (DMA) and monomethylarsinic acid (MMA) content of seed and rhizosphere soil. The results indicate a probable role of NBRI 0716 in As methylation as the possible mechanism for maneuvering As stress in chickpea. Analysis of functional diversity using carbon source utilization (Biolog) showed significant difference in diversity and evenness indices among the soil microbial rhizosphere communities. Microbial diversity loss caused by As were prevented in the presence of Trichoderma NBRI 0716. PMID:25839184

    Chickpea is a heat sensitive crop hence its potential yield is considerably reduced under high temperatures exceeding 35 °C. In the present study, we evaluated the efficacy of proline in countering the damage caused by heat stress to growth and to enzymes of carbon and antioxidative metabolism in chickpea. The chickpea seeds were raised without (control) and with proline (10 μM) at temperatures of 30/25 °C, 35/30 °C, 40/35 °C and 45/40 °C as day/ night (12 h/12 h) in a growth chamber. The sho...

  1. Effects of Fungicides, Essential Oils and Gamma Irradiated Bioagents on Chickpea Root Rot Caused by Sclerotium rolfsii

    International Nuclear Information System (INIS)

    Sclerotium rolfsii (S. rolfsii) causes root rot disease in several crops including Cicer arietinum (chickpea) that results in low yield. In vitro experiments on fungicides, vitavax and monceren T, and essential oils, clove and mint oils, were conducted to control root rot disease of chickpea caused by S. rolfsii. The treatments resulted in 80 % suppression of root rot disease. Gliocladium virens (G. virens) and Gliocladium deliquescens (G. deliquescens) were effective as biocontrol agents against S. rolfsii. The results showed that these treatments greatly reduced the root rot disease in chickpea. In this study, the effect of gamma irradiation at doses 0, 0.25, 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 kGy on the pathogenecity of G. virens and G. deliquescens against S. rolfsii were investigated. The results revealed that gamma irradiation increased the pathogenecity of G. virens and G. deliquescens against S. rolfsii

    Full Text Available Abstract Background Chickpea (C. arietinum L. ranks third in food legume crop production in the world. However, drought poses a serious threat to chickpea production, and development of drought-resistant varieties is a necessity. Unfortunately, cultivated chickpea has a high morphological but narrow genetic diversity, and understanding the genetic processes of this plant is hindered by the fact that the chickpea genome has not yet been sequenced and its EST resources are limited. In this study, two chickpea varieties having contrasting levels of drought-tolerance were analyzed for differences in transcript profiling during drought stress treatment by withdrawal of irrigation at different time points. Transcript profiles of ESTs derived from subtractive cDNA libraries constructed with RNA from whole seedlings of both varieties were analyzed at different stages of stress treatment. Results A series of comparisons of transcript abundance between two varieties at different time points were made. 319 unique ESTs available from different libraries were categorized into eleven clusters according to their comparative expression profiles. Expression analysis revealed that 70% of the ESTs were more than two fold abundant in the tolerant cultivar at any point of the stress treatment of which expression of 33% ESTs were more than two fold high even under the control condition. 53 ESTs that displayed very high fold relative expression in the tolerant variety were screened for further analysis. These ESTs were clustered in four groups according to their expression patterns. Conclusions Annotation of the highly expressed ESTs in the tolerant cultivar predicted that most of them encoded proteins involved in cellular organization, protein metabolism, signal transduction, and transcription. Results from this study may help in targeting useful genes for improving drought tolerance in chickpea.

    Low inorganic phosphate (Pi) availability is a major constraint for efficient nitrogen fixation in legumes, including chickpea. To elucidate the mechanisms involved in nodule acclimation to low Pi availability, two Mesorhizobium-chickpea associations exhibiting differential symbiotic performances, Mesorhizobium ciceri CP-31 (McCP-31)-chickpea and Mesorhizobium mediterranum SWRI9 (MmSWRI9)-chickpea, were comprehensively studied under both control and low Pi conditions. MmSWRI9-chickpea showed a lower symbiotic efficiency under low Pi availability than McCP-31-chickpea as evidenced by reduced growth parameters and down-regulation of nifD and nifK These differences can be attributed to decline in Pi level in MmSWRI9-induced nodules under low Pi stress, which coincided with up-regulation of several key Pi starvation-responsive genes, and accumulation of asparagine in nodules and the levels of identified amino acids in Pi-deficient leaves of MmSWRI9-inoculated plants exceeding the shoot nitrogen requirement during Pi starvation, indicative of nitrogen feedback inhibition. Conversely, Pi levels increased in nodules of Pi-stressed McCP-31-inoculated plants, because these plants evolved various metabolic and biochemical strategies to maintain nodular Pi homeostasis under Pi deficiency. These adaptations involve the activation of alternative pathways of carbon metabolism, enhanced production and exudation of organic acids from roots into the rhizosphere, and the ability to protect nodule metabolism against Pi deficiency-induced oxidative stress. Collectively, the adaptation of symbiotic efficiency under Pi deficiency resulted from highly coordinated processes with an extensive reprogramming of whole-plant metabolism. The findings of this study will enable us to design effective breeding and genetic engineering strategies to enhance symbiotic efficiency in legume crops. PMID:27450089

    Full Text Available Abstract Background Chickpea (Cicer arietinum L., an important grain legume crop of the world is seriously challenged by terminal drought and salinity stresses. However, very limited number of molecular markers and candidate genes are available for undertaking molecular breeding in chickpea to tackle these stresses. This study reports generation and analysis of comprehensive resource of drought- and salinity-responsive expressed sequence tags (ESTs and gene-based markers. Results A total of 20,162 (18,435 high quality drought- and salinity- responsive ESTs were generated from ten different root tissue cDNA libraries of chickpea. Sequence editing, clustering and assembly analysis resulted in 6,404 unigenes (1,590 contigs and 4,814 singletons. Functional annotation of unigenes based on BLASTX analysis showed that 46.3% (2,965 had significant similarity (≤1E-05 to sequences in the non-redundant UniProt database. BLASTN analysis of unique sequences with ESTs of four legume species (Medicago, Lotus, soybean and groundnut and three model plant species (rice, Arabidopsis and poplar provided insights on conserved genes across legumes as well as novel transcripts for chickpea. Of 2,965 (46.3% significant unigenes, only 2,071 (32.3% unigenes could be functionally categorised according to Gene Ontology (GO descriptions. A total of 2,029 sequences containing 3,728 simple sequence repeats (SSRs were identified and 177 new EST-SSR markers were developed. Experimental validation of a set of 77 SSR markers on 24 genotypes revealed 230 alleles with an average of 4.6 alleles per marker and average polymorphism information content (PIC value of 0.43. Besides SSR markers, 21,405 high confidence single nucleotide polymorphisms (SNPs in 742 contigs (with ≥ 5 ESTs were also identified. Recognition sites for restriction enzymes were identified for 7,884 SNPs in 240 contigs. Hierarchical clustering of 105 selected contigs provided clues about stress- responsive

    International Nuclear Information System (INIS)

    A field experiment was carried out at the Plant Nutrition and Fertilization Unit, Soils and Water Research Department, Nuclear Research Center, Atomic Energy Authority, Inshas, Egypt on wheat and chickpea inter cropping. The Objective of this current work is to study Organic matter decomposition under clean agriculture system in sandy soil using nuclear technique. The lowest portion of nitrogen derived from fertilizer was resulted from application of compost and chickpea straw treatments. It is worthy to mention that full recommend dos of fertilizer (20 kg N fed-1) was efficiently used by shoots of chickpea plants. Portion of nitrogen derived from fertilizer by seeds of chickpea was lower than those recorded with shoots. Generally, there was no big significant difference between nitrogen gained by shoots and seeds from the organic materials. This holds true with all treatments. More declines in nitrogen derived from soil percentages were resulted from application of cow manure and compost treatments under different rate of mineral fertilizer, the application 100% MF treatment induced higher nitrogen derived from soil pool as compared to the other treatments. The best value of nitrogen derived from air was detected followed by compost, while the lowest value was recorded with wheat straw. In general, nitrogen derived from air by shoots lower than those up taken by seeds of chickpea plant. Application of wheat straw and compost treatments were enhanced the nitrogen derived from fertilizer by straw of wheat plant as compared to caw manure, maize stalk, chickpea straw, but Ndff% in grains of wheat , cow manure and maize stalk increased as compared to the other treatment. Application of organic materials, chickpea straw and cow manure achieved the highest value of Ndfo% by straw of wheat plant as compared to maize stalk, compost and wheat straw. But values of nitrogen derived from organic in grains of wheat plants, the application of chickpea straw and wheat straw

  8. Influence of water deficit on transpiration and radiation use efficiency of chickpea (Cicer arietinum L.)

    International Nuclear Information System (INIS)

    Information on the relationship between biomass production, radiation use and water use of chickpea (Cicer arietinum L.) is essential to estimate biomass production in different water regimes. Experiments were conducted during three post-rainy seasons on a Vertisol (a typic pallustert) to study the effect of water deficits on radiation use, radiation use efficiency (RUE), transpiration and transpiration efficiency (TE) of chickpea. Different levels of soil water availability were created, either by having irrigated and non-irrigated plots or using a line source. Biomass production was linearly related to both cumulative intercepted solar radiation and transpiration in both well watered and water deficit treatments. Soil water availability did not affect RUE (total dry matter produced per unit of solar radiation interception) when at least 30% of extractable soil water (ESW) was present in the rooting zone, but below 30% ESW, RUE decreased linearly with the decrease in soil water content. RUE was also significantly correlated (R2 = 0.61, P < 0.01) with the ratio of actual to potential transpiration (T/Tp) and it declined curvilinearly with the decrease in T/Tp. TE decreased with the increase in saturation deficit (SD) of air. Normalization of TE with SD gave a conservative value of 4.8 g kPa kg−1. To estimate biomass production of chickpea in different environments, we need to account for the effect of plant water deficits on RUE in a radiation-based model and the effect of SD on TE in a transpiration-based model.

    the effect of gradual increase in fertilizer-N rates added to chickpea plants that cultivated in pots packed with light textured soil collected from surrounding area of biotechnology research center, libya was examined in pot experiment. seeds were inoculated with rhizobium strain as peat-based inocula or in liquid culture. Also, un inoculated treatment was included. 15 N-labelled urea(5% atom excess) was applied as N-fertilizer source at rates of 0,20, 40,60,80 and 100 Kg N ha-1. growth parameters of chickpea plants were positively affected by N-fertilizer but bacterial inoculation did not reflected significant difference with levels of 40,60 and 80 kg ha-1..dry matter accumulation was increased with increasing N fertilizer levels up to 80 Kg N ha-1 as compared to the unfertilized control then decreased at the level of 100 kg N ha-1. this holds true under inoculated and un inoculated treatments. similar trend was noticed with nitrogen uptake by chickpea shoots.accordingly, portion of N derived from fertilizer had been increased. nitrogen fixation (% N dfa), as estimated using isotope dilution approach, was increased with increasing N rates up to moderate additions (60 kg N ha-1) , then tended to decrease. Rhizobium inoculation has an important effect on enhancement of plant growth and N acquisition when low to moderate levels of fertilizer was added. The results obtained in this work suggests application of bio fertilization technology in combination with chemical fertilizers under field conditions to get advanced to generalize the data released from such investigations

    Full Text Available Abstract Background Chickpea is a major crop in many drier regions of the world where it is an important protein-rich food and an increasingly valuable traded commodity. The wild annual Cicer species are known to possess unique sources of resistance to pests and diseases, and tolerance to environmental stresses. However, there has been limited utilization of these wild species by chickpea breeding programs due to interspecific crossing barriers and deleterious linkage drag. Molecular genetic diversity analysis may help predict which accessions are most likely to produce fertile progeny when crossed with chickpea cultivars. While, trait-markers may provide an effective tool for breaking linkage drag. Although SSR markers are the assay of choice for marker-assisted selection of specific traits in conventional breeding populations, they may not provide reliable estimates of interspecific diversity, and may lose selective power in backcross programs based on interspecific introgressions. Thus, we have pursued the development of gene-based markers to resolve these problems and to provide candidate gene markers for QTL mapping of important agronomic traits. Results An EST library was constructed after subtractive suppressive hybridization (SSH of root tissue from two very closely related chickpea genotypes (Cicer arietinum. A total of 106 EST-based markers were designed from 477 sequences with functional annotations and these were tested on C. arietinum. Forty-four EST markers were polymorphic when screened across nine Cicer species (including the cultigen. Parsimony and PCoA analysis of the resultant EST-marker dataset indicated that most accessions cluster in accordance with the previously defined classification of primary (C. arietinum, C. echinospermum and C. reticulatum, secondary (C. pinnatifidum, C. bijugum and C. judaicum, and tertiary (C. yamashitae, C. chrossanicum and C. cuneatum gene-pools.

    In this study, novel fermented chickpea milk with high γ -aminobutyric acid (GABA) content and potential neuroprotective activity was developed. Fermentation starter that can produce GABA was selected from 377 strains of lactic acid bacteria isolated from traditional Chinese fermented foods. Among the screened strains, strain M-6 showed the highest GABA-producing capacity in De Man-Rogosa and Sharp (MRS) broth and chickpea milk. M-6 was identified as Lactobacillus plantarum based on Gram staining, API carbohydrate fermentation pattern testing, and 16s rDNA sequencing. The complete gene encoding glutamate decarboxylase was cloned to confirm the presence of the gene in L. plantarum M-6. The fermentation condition was optimized by response surface methodology. Results demonstrated that L. plantarum M-6 produced the highest GABA content of 537.23 mg/L. The optimal condition included an inoculum concentration of 7%, presence of 0.2% (m/v) monosodium glutamate and 55 µ M pyridoxal-5-phosphate, incubation temperature of 39 °C and fermentation time of 48 h . GABA-enriched chickpea milk exerted protective effects on PC12 cells against MnCl2 -induced injury. GABA-enriched chickpea milk improved cell viability and markedly attenuated the release of lactate dehydrogenase compared with the impaired cells. PMID:27602272

The complete gene encoding glutamate decarboxylase was cloned to confirm the presence of the gene in L. plantarum M-6. The fermentation condition was optimized by response surface methodology. Results demonstrated that L. plantarum M-6 produced the highest GABA content of 537.23 mg/L. The optimal condition included an inoculum concentration of 7%, presence of 0.2% (m/v) monosodium glutamate and 55 µ M pyridoxal-5-phosphate, incubation temperature of 39 °C and fermentation time of 48 h . GABA-enriched chickpea milk exerted protective effects on PC12 cells against MnCl2 -induced injury. GABA-enriched chickpea milk improved cell viability and markedly attenuated the release of lactate dehydrogenase compared with the impaired cells. PMID:27602272

  19. GGE biplot analysis based selection of superior chickpea (cicer arietinum L.) inbred lines under variable water environments

    International Nuclear Information System (INIS)

    Chickpea is an important legume crop and grown mainly on the marginal lands in Pakistan. Insufficient and erratic water availability is severe problem for this crop. Hence, breeding chickpea for low moisture stress tolerance is absolutely important in this era of climate change. Research work was started with evaluation of mini core collection of 450 chickpea lines and 42 lines were retained after three years of selection under different water treatments. These 42 lines were used in current study for evaluation and further selection under three water treatments. Detailed study on these lines was conducted under irrigated, rainfed and tunnel conditions (no rainfall and irrigation) during 2012-13 and 2013-14. Data were collected for yield and yield components which were subjected to analysis of variance and GGE biplot analysis. Analysis showed highly significant differences among lines for all traits under study. Mean comparison showed less differences between irrigated and rainfed conditions than tunnel for all traits. GGE biplot ranked chickpea lines as; above average, below average, stable, unstable and ideally performing. Lines present closer to ideal genotype on GGE biplot were worthy for selection because these had higher mean values with stable performances across different water treatments. The ideal lines in these experiments; K008-11, CM1592/08, CM526/05, D089-11, TGDX201, D094-11 and K051-11 were selected with higher yield potential. (author)

This hybrid transcriptome assembly, referred to as Cicer arietinumTranscriptome Assembly version 2 (CaTA v2, available at http://data.comparative-legumes.org/transcriptomes/cicar/lista_cicar-201201, comprising 46,369 transcript assembly contigs (TACs has an N50 length of 1,726 bp and a maximum contig size of 15,644 bp. Putative functions were determined for 32,869 (70.8% of the TACs and gene ontology assignments were determined for 21,471 (46.3%. The new transcriptome assembly was compared with the previously available chickpea transcriptome assemblies as well as to the chickpea genome. Comparative analysis of CaTA v2 against transcriptomes of three legumes - Medicago, soybean and common bean, resulted in 27,771 TACs common to all three legumes indicating strong conservation of genes across legumes. CaTA v2 was also used for identification of simple sequence repeats (SSRs and intron spanning regions (ISRs for developing molecular markers. ISRs were identified by aligning TACs to the Medicago genome, and their putative mapping positions at chromosomal level were identified using transcript map of chickpea. Primer pairs were designed for 4,990 ISRs, each representing a single contig for which predicted positions are inferred and distributed across eight linkage groups. A subset of randomly selected ISRs representing all eight chickpea linkage groups were validated on five chickpea genotypes and showed 20% polymorphism with average polymorphic information content (PIC of 0.27. In summary, the hybrid transcriptome assembly developed and novel markers identified can be used for a variety of applications such as gene discovery, marker-trait association, diversity analysis etc., to advance genetics research and breeding

  2. Production of wheat preceded with fallow versus continuous wheat or following chickpea or lentil in the Syrian Arab Republic

    International Nuclear Information System (INIS)

    Two crop rotation experiments with 9 treatments and 4 replicates were laid down in a split plot design two sides, in the Northern and Southern Provinces of Syria. The experimental treatments were three 2-course crop rotations: fallow-wheat, chickpea/lentil-wheat and wheat-wheat (continuous wheat), with three rates of N fertilizer applications. 15N-labelled fertilizer was used as tracer to measure fertilizer use efficiency (UFE) and residual N transferred to the second, subsequent crop in the rotation. Total dry matter production of wheat following legumes was higher than continuous wheat or fallow-wheat rotation. Depending on soil inorganic N, dry matter yields were either increased with N addition or there was almost no effect. Measurements of soil water content during the growing season showed that the soil water storage over depth of 120 cm at harvest was higher after fallow than after chickpea, lentil or wheat. However, the observed differences were diminished at the beginning of the subsequent growing season. Contributions of fertilizer N to total N yield were 5-20% for wheat, 1-4% for chickpea, and 4% for lentil. Chickpea fixed 46-127 kg N ha-1 which contributed 65-85% of the total N yield in the crop. Fixed nitrogen was somewhat low for lentil, amounting to only 22-32% of the total N yield. Mineral nitrogen enrichment of the soil resulting from fallow was about 8-13 kg N ha-1. Residual N transferred to the subsequent wheat crop from lentil was rather low. However, it was detectable (3 kg N ha-1). No residual N benefits could be measured from chickpea. Fertilizer use efficiency varied depending on the crop: 22-57, 17-21, and 8-12% for wheat, lentil and chickpea, respectively. Rotation revenues, based on equivalent starch values (STE) from one cycle of rotation showed that wheat-wheat and chickpea-wheat rotations had almost similar revenues. However, they were higher than lentil-wheat and fallow-wheat rotations. (author). 8 refs, 9 figs, 4 tabs

    Full Text Available Eight " kabuli " chickpea genotypes Beja1, Amdoun1, Nayer, Kasseb, Bochra, FLP96-114C, FLP88-42C and Chetoui were germinated, in two in vitro culture media, particularly, agar and filter paper Watman n°2 and under tree osmotic water pressures (OWP: -0,33; -4 and -8 bars induced by PEG8000. On filter paper, germination appeared more accelerated with a higher rate compared to the agar media. Osmotic water stress has negatively affected the seeds germination and the seedlings vegetative development parameters. Osmotic water pressure - 8 bars completely inhibited seeds germination on filter paper media. On the other hand, on agar media, it caused a feeble germination rate and a stunting of the seedlings. A broad genotypic variability of the chickpea cultivars was revealed toward the osmotic water stress. Tolerance index to osmotic water stress revealed three groups of cultivars: (1 Nayer and Kasseb are tolerant, (2 Bochra, FLIP88-42C and Chetoui are fairly tolerant and (3 Amdoun1, Beja1 and FLIP96-114C are sensitive to this abiotic stress.

    Full Text Available Broad-leaved weeds constitute a serious problem in the production of winter legumes, but few selective herbicides controlling these weeds have been registered in Europe. Four field experiments were conducted in 2009/10 and repeated in 2010/11 in Greece to study the response of common vetch (Vicia sativa L., lentil (Lens culinaris Medik., chickpea (Cicer arietinum L. and red pea (Lathyrus cicera L. to several rates of the herbicides pendimethalin, S-metolachlor, S-metolachlor plus terbuthylazine and flumioxazin applied pre-emergence, as well as imazamox applied post-emergence. Phytotoxicity, crop height, total weight and seed yield were evaluated during the experiments. The results of this study suggest that common vetch, lentil, chickpea and red pea differed in their responses to the herbicides tested. Pendimethalin at 1.30 kg ha-1, S-metolachlor at 0.96 kg ha-1 and flumioxazine at 0.11 kg ha-1 used as pre-emergence applied herbicides provided the least phytotoxicity to legumes. Pendimethalin at 1.98 kg ha-1 and both rates of S-metolachlor plus terbuthylazine provided the greatest common lambsquarters (Chenopodium album L. control. Imazamox at 0.03 to 0.04 kg ha-1 could also be used as early post-emergence applied herbicide in common vetch and red pea without any significant detrimental effect.

  6. Effect of P application methods on yield of chickpea (Cicer arietinum L.) and P utilization

    International Nuclear Information System (INIS)

    Broadcast and placement techniques for P application were evaluated in relation to P utilization in chickpea on sandy loam alluvial soil (Typic, Ustochrept) at Indian Agriculture Research Institute (IARI) farm. Grain yield response per unit quantity of added P was highest at lowest rate of P application. A significant increase in total P uptake was noticed with subsequent increase in the dose of application upto 60 kg P2O5/ha, while percent P utilization declined steadily from 16.5 to 7.5 with increase in the levels of phosphate from 30 to 90 kg P2O5/ha respectively. Placement of phosphate at 3-4 cm below the seed proved superior to broadcast as noted by significantly higher values of grain yield, per cent P utilization and P uptake at flowering as well as maturity. Moreover, the results from alternate tagging technique conclusively indicated that chickpea derived relatively more P from the basal dose than from the siderdressed fertilizer.

  7. Comparative efficacy of different fungicides against fusarium wilt of chickpea (cicer arietinum l.)

    International Nuclear Information System (INIS)

    Fusarium wilt caused by Fusarium oxysporum f. sp. ciceris (Foc) is the most serious and widespread disease of chickpea, causing a 100% loss under favorable conditions. Fourteen fungicides were evaluated against wilt pathogen In vitro with five different concentrations ranging from 1-10000 ppm. Among these only Carbendazim and Thiophanate-methyl was found as the most effective at all used concentrations. Other fungicides like Aliette, Nativo, Hombre-excel and Dividend star were found to be moderately effective. Whereas, remaining fungicides were ineffective against the targeted pathogen. Generally, a positive co-relation was observed between increasing concentrations of the tested fungicides and inhibition of Foc. Based on In vitro results Carbendazim, Thiophanate-methyl, Aliette, Dividend-star, Hombre-excel, Score and Nativo were selected for pot and field experiments. The higher concentrations of the few fungicides completely inhibited the pathogen as well as found to be phytotoxic and suppressed the plant growth while lower concentrations promoted the growth of chickpea plants. On over all bases, the Carbendazim and Thiophanate-methyl, followed by Aliette and Nativo were more effective in reducing the impact of pathogen as well as enhancing the plant growth in greenhouse experiment. Under field conditions, all fungicides except Score remarkably decreased the disease development and subsequently increased the plant growth as well as grain yield as compared to untreated plants.

  8. Effect of radiation and soaking on trypsin inhibitor and protein content of chickpea (Cicer arietinum L.)

    International Nuclear Information System (INIS)

    Composition of Ascochyta-blight resistant chickpea for proximate components, vitamins, energy and trypsin inhibitor, was determined. The influence of irradiation and soaking at ambient temperatures (25-35deg C) on trypsin inhibitor activity (TIA) and protein content of chickpea, was investigated. A significant linear relation (r = -0.960 to -0.987) was found between the loss of TIA and soaking time of irradiated and unirradiated seeds (p < 0.05) and the rate of loss increased with increasing radiation dose (0.25-1.00 kGy). However, effect of radiation alone was negligible. Maximum decrease (30.7%) in TIA (from 330.0 to 228.6 TiU/g) occurred during soaking for 12 h of 1.00 kGy sample. The protein contents increased from an initial value of 21.7% to 23.4% and 22.7% as a result of soaking for 12 h in tap and distilled waters, respectively. Radiation treatment exhibited little or no effect. (author)

    2010-12-15

    Chickpea grown in fly ash (FA) treated soil (25, 50, and 100% FA) was used to evaluate the effect of FA on antioxidants, metal concentration (Fe, Zn, Cu, Cr, and Cd), photosynthetic pigments (chlorophyll a (chl-a), chlorophyll b (chl-b), total chlorophyll (total chl), and carotenoids), growth and yield performance. All antioxidants in roots, shoots and leaves of chickpea increase with increasing FA doses to combat FA stress. The activities of antioxidants were more in the root tissues to cope with stress induced in the plants as compared to shoot and leaf. Concentration of metals was found maximum in roots than the shoots and seeds. The highest concentration of Fe and lowest level of Cd were recorded in all treatments of FA for different parts of the plant. The treated crop showed reduced level of chlorophyll but enhanced level of carotenoids and protein. However, root length, number of nodules and biomass in 25 and 50% FA treatments did not differ significantly in comparison to respective control plants. These results suggest that heavy metals of FA causes oxidative stress in this crop and the antioxidant enzymes could help a pivotal role against oxidative injury.

  10. Evaluation of N2 fixation by nodulation-variants of chickpea in India

    International Nuclear Information System (INIS)

    Five nodulation-variants of chickpea (Cicer arietinum L.) cv. ICC 5003, delineated on the basis of visual ratings ('S1' for minimum nodulation to 'S5' for maximum), were used to investigate the optimum levels of nodulation and N2 fixation for growth and yield. Two field experiments were conducted, with fertilizer N (enriched in 15N) applied at 10 ('N1') or 100 kg ha-1 ('N2') on contrasting soils in different years; plants were evaluated for nodulation, growth, N2 fixation and yield. Experiment 2 included high-nodulating (HN) and low-nodulating (LN) selections of cvv. ICC 4948, ICC 14196 and Kourinsky. Non-nodulating selections of chickpea were included as references to quantify N2 fixation. In both experiments the trends in amounts of N fixed by the five selections at N1 were similar when assessed by 15N-enriched and by N-difference methods. The percent N derived from N2 fixation (estimated from 15N data) correlated with yield and amount of N fixed in Experiment 2, but not Experiment 1. The relative nodulation differences were consistent across locations; the S4 and S5 (and HN) lines were generally superior to S1 and S2 (and LN) for nodulation, N2-fixation, total dry matter and grain yield. Nodule number and mass correlated significantly (P2-fixed in both experiments

  11. Screening of ten advanced chickpea lines for blight and wilt resistance

    International Nuclear Information System (INIS)

    Ten advanced chickpea lines developed at NIAB were screened for resistance to Ascochyta blight and Fusarium wilt diseases in different sets of experiments conducted under controlled environment. Inoculation of plants by spore suspension of virulent strains of Ascochyta rabiei revealed that one line (97313) was resistant tolerant, two lines (97305, 97392) were tolerant, six lines (97306, 97310, 97311, 97303, 97302, 97393) were tolerant/susceptible and one line (97301) was susceptible. Screening of the same lines against Fusarium wilt by water culture method showed that two lines (97301, 97313) were moderately resistant, four lines (97302, 97303, 97306, 97393) were tolerant and the remaining four lines were susceptible. Screening through phytotoxic culture filtrates revealed that two lines (97302, 97313) were less sensitive to culture filtrates of Ascochyta rabiei and Fusarium oxysporum than the resistant check (CM88). These lines were also analyzed spectrophotometrically for peroxidase enzyme activity. Maximum enzyme activity was detected after 48 hours of inoculation with A. rabiei in three lines (97305, 97311, 97313) and resistant check (CM88) while enzyme activity in the remaining lines reached its maximum after 72 hours of inoculation which was comparable to the susceptible check (Pb-1). These studies lead to the conclusion that one line (97313) exhibited resistance against both the diseases and can be used as a source of resistance for further improvement of chickpea germplasm.

  12. Thermoluminescence studies of calcite extracted from natural sand used in making roasted chickpea

    International Nuclear Information System (INIS)

    In this study, thermoluminescence (TL) properties of the calcite extracted from natural sand which is used in making roasted chickpeas were investigated. And also the effects of different thermal treatments on thermoluminescence glow curve were observed. Two distinct TL peaks were observed at ∼130 °C and ∼230 °C. The annealing of sample, especially at 900 °C, causes a huge enhancement in sensitization of TL. Linearity in dose response is observed for the values up to 0.6 kGy and above 0.6 kGy linearity is not preserved and dose response becomes sublinear. The best reproducibility is obtained when the samples are annealed between 400°C and 600 °C. - Highlights: • The natural sand sample used in making roasted chickpea shows thermoluminescence properties. • Annealing at 900 °C for about 15 min gives best TL output. • A good sensitization of about 70 factor was observed in annealed samples when they were compared with no annealed samples. • At doses lower than 0.6 kGy, dose response is linear and sublinear at doses higher than 0.6 kGy. • The best reproducibility is obtained when the samples are annealed between 400 °C and 600 °C

    Full Text Available Crop-rhizobium symbiosis can be influenced by leaching of herbicides which is unavoidable after their application. Due to an adjuvant which might help to develop the low-use-rate of herbicide, an experiment was carried out to compare the impact of the recommended rate (1200 g active ingredient ha-1 and the optimized rate (282.15 g active ingredient ha-1 of pyridate on the biological properties of eight chickpea cultivars inoculated with Mesorhizobium mediterraneum, grown in pots. Based on the required rate of herbicide to give 95% control of common lambsquarters (Chenopodium album L. value, the efficacy of pyridate improved up to 3.87-fold by adding methylated rapeseed oil to spray solution. The ‘Desi’ cultivar had significantly higher nodulation than ‘Kabuli’ cultivar. In general, toxicity of the recommended rate was higher than the optimized rate. With the exception of root dry weight, all of the measured parameters were significantly affected by the recommended rate of pyridate in varying degrees. The symbiotic properties of chickpea cultivars were affected more than 10% at the recommended dose. The reduced nodulation ranged from 29% to 73% among cultivars exposed to pyridate at the recommended dose. The ‘Desi’ cultivar was more sensitive than the ‘Kabuli’ to the recommended rate of pyridate. We may conclude that effective low-use-rate of pyridate via applying of activator adjuvants should be noted.

    A comparative study of frequency and spectrum of chlorophyll mutations induced by two physical (gamma rays, fast neutrons) and two chemical mutagens (NMU, EMS) in relation to the effects in M1 plants and induction of mutations in M2 was made in four chickpea (Cicer arietinum L.) varieties, two desi (G 130 & H 214) one Kabuli (C 104) and one green seeded (L 345). The treatments included three doses each of gamma rays (400, 500 & 600 Gy) and fast neutrons (5, 10 & 15 Gy) and two concentrations with two different durations of two chemical mutagens, NMU [0.01% (20h), & 0.02% (8h)] and EMS [0.1% (20h) & 0.2% (8h)]. The frequencies and spectrum of three different kinds of induced chlorophyll mutations in the order albina (43.5%), chlorina (27.3%) and xantha (24.2%) were recorded. Chemical mutagens were found to be efficient in inducing chlorophyll mutations in chickpea. Highest frequency of mutations was observed in green seeded var. L 345 (83% of M1 families and 19.9/1000 M2 plants). Kabuli var. C 104 was least responsive for chlorophyll mutations

    Full Text Available Abstract Background Chickpea (Cicer arietinum L. is an important grain-legume crop that is mainly grown in rainfed areas, where terminal drought is a major constraint to its productivity. We generated expressed sequence tags (ESTs by suppression subtraction hybridization (SSH to identify differentially expressed genes in drought-tolerant and -susceptible genotypes in chickpea. Results EST libraries were generated by SSH from root and shoot tissues of IC4958 (drought tolerant and ICC 1882 (drought resistant exposed to terminal drought conditions by the dry down method. SSH libraries were also constructed by using 2 sets of bulks prepared from the RNA of root tissues from selected recombinant inbred lines (RILs (10 each for the extreme high and low root biomass phenotype. A total of 3062 unigenes (638 contigs and 2424 singletons, 51.4% of which were novel in chickpea, were derived by cluster assembly and sequence alignment of 5949 ESTs. Only 2185 (71% unigenes showed significant BLASTX similarity ( Conclusion Our study compares not only genes that are up- and down-regulated in a drought-tolerant genotype under terminal drought stress and a drought susceptible genotype but also between the bulks of the selected RILs exhibiting extreme phenotypes. More than 50% of the genes identified have been shown to be associated with drought stress in chickpea for the first time. This study not only serves as resource for marker discovery, but can provide a better insight into the selection of candidate genes (both up- and downregulated associated with drought tolerance. These results can be used to identify suitable targets for manipulating the drought-tolerance trait in chickpea.

    In Italy, meteorological data necessary and useful for climate studies are collected, processed and archived by a wide range of national and regional institutions. As a result, the density of the stations, the length and frequency of the observations, the quality control procedures and the database structure vary from one dataset to the other. In order to maximize the use of those data for climate knowledge and climate change assessments, a computerized system for the collection, quality control, calculation, regular update and rapid dissemination of climate indicators (denominated SCIA) was developed. Along with the pieces of information provided by complete metadata, climate indicators consist of statistics (mean, extremes, date of occurrence, standard deviation) over ten-days, monthly and yearly time periods of meteorological variables, including temperature, precipitation, humidity, wind, water balance, evapotranspitaton, degree-days, cloud cover, sea level pressure, solar radiation. In addition, normal values over thirty-year reference climatological periods and yearly anomalies are calculated and made available. All climate indicators, as well as their time series at a single location or spatial distribution at a selected time, are available through a dedicated web site (www.scia.sinanet.apat.it). In addition, secondary products like high resolution temperature maps obtained by kriging spatial interpolation, are made available. Over the last three years, about 40000 visitors accessed to the SCIA web site, with an average of 45 visitors per day. Most frequent visitors belong to categories like universities and research institutes; private companies and general public are present as well. Apart from research purposes, climate indicators disseminated through SCIA may be used in several socio-economic sectors like energy consumption, water management, agriculture, tourism and health. With regards to our activity, we base on these indicators for the estimation of climate trends needed for climate impact and vulnerability assessment over Italy, and as a contribution to the national communications to the UNFCCC. For this purpose, homogenization procedures are carried out on the longest and most complete time series, in order to filter out non-climatic signals; in addition, statistical models are applied for trend estimates on the most important climate indicators such as averages and extremes of temperature and precipitation.

    Cold stress (CS) signals are translated into physiological changes as products of direct and/or indirect of gene expression regulated by different factors like DNA methylation. In this study, some of these factors were comparatively studied in two chickpea (Cicer arietinum L.) genotypes (Sel96Th11439, cold-tolerant genotype, and ILC533, cold susceptible one) under control (23 °C) and days 1, 3, and 6 after exposing the seedlings to CS (4 °C). Under CS, tolerant genotype prevented H2O2 accumulation which led to a decrease in damage indices (malondialdehyde and electrolyte leakage index) compared to susceptible one. The significant activities of antioxidant enzymes (superoxide dismutase, catalase, ascorbate peroxidase, guaiacol peroxidase, and polyphenol oxidase) along with a significant proportion of change in DNA methylation/demethylation patterns were often effective factors in preserving cell against cold-induced oxidative stress. Chickpea cells in response to CS changed access to their genome as the number of bands without change from day 1 to day 6 of exposure to CS particularly in tolerant genotype was decreased. During CS, the methylation level was higher compared to demethylation (29.05 vs 19.79 %) in tolerant genotype and (27.92 vs 22.09 %) in susceptible one. However, for prolonged periods of CS, changes in demethylated bands in tolerant genotype were higher than that of in susceptible one (9.24 vs 4.13 %), indicating higher potential for activation of CS responsive genes. Such a status along with higher activity of antioxidants and less damage indices could be related to cold tolerance (CT) mechanisms in chickpea. Sequencing analysis confirmed the important role of some specific DNA sequences in creating CT with possible responsive components involved in CS. Thus, dynamic assessment using multi-dimensional approaches allows us to progressively fill in the gaps between physio-biochemical and molecular events in creating CT, to comprehend better the

    A transcript map has been constructed by the development and integration of genic molecular markers (GMMs) including single nucleotide polymorphism (SNP), genic microsatellite or simple sequence repeat (SSR) and intron spanning region (ISR)-based markers, on an inter-specific mapping population of chickpea, the third food legume crop of the world and the first food legume crop of India. For SNP discovery through allele re-sequencing, primer pairs were designed for 688 genes/expressed sequence tags (ESTs) of chickpea and 657 genes/ESTs of closely related species of chickpea. High-quality sequence data obtained for 220 candidate genic regions on 2-20 genotypes representing 9 Cicer species provided 1,893 SNPs with an average frequency of 1/35.83 bp and 0.34 PIC (polymorphism information content) value. On an average 2.9 haplotypes were present in 220 candidate genic regions with an average haplotype diversity of 0.6326. SNP2CAPS analysis of 220 sequence alignments, as mentioned above, provided a total of 192 CAPS candidates. Experimental analysis of these 192 CAPS candidates together with 87 CAPS candidates identified earlier through in silico mining of ESTs provided scorable amplification in 173 (62.01%) cases of which predicted assays were validated in 143 (82.66%) cases (CGMM). Alignments of chickpea unigenes with Medicago truncatula genome were used to develop 121 intron spanning region (CISR) markers of which 87 yielded scorable products. In addition, optimization of 77 EST-derived SSR (ICCeM) markers provided 51 scorable markers. Screening of easily assayable 281 markers including 143 CGMMs, 87 CISRs and 51 ICCeMs on 5 parental genotypes of three mapping populations identified 104 polymorphic markers including 90 markers on the inter-specific mapping population. Sixty-two of these GMMs together with 218 earlier published markers (including 64 GMM loci) and 20 other unpublished markers could be integrated into this genetic map. A genetic map developed here

    -conventional water resources such as saline/brackish water and treated waste water for irrigation. With this in mind, an experiment was conducted in the south of Morocco to investigate the effect of irrigation with saline water on a local variety of chickpea. Irrigation with water of different salinity levels...... was carried out on pot experiments. Differences in water uptake and plant growth; as well as proline, soluble sugar, and Na+ and K+ contents of the plant were quantified. The results showed a negative relationship between increasing water salinity and most of the measured plant growth parameters. Irrigation...... these threshold values one may expect the crop yield parameters to be affected. The quantified responses also indicate the rate of change of yield parameters in response to the irrigation water salinity level. This could help in avoiding significant yield reduction when deciding on the irrigation water salinity...

Bioactive samples were made by varying solvent extraction of the culture broths of the potent isolates belongs to Actinomycetes, Pseudomonas, Bacillus and Trichoderma. The efficacy of the isolates to produce other potent antifungal metabolites such as cell wall degrading enzymes, HCN and volatile compounds were also checked. Treatment with antagonistic isolates in vivo under greenhouse conditions revealed significant reduction of the disease intensity of foot rot disease of black pepper and collar rot of chick pea.

  6. Effect of irradiation and germination on trypsin inhibitor and protein content of chickpea (Cicer arietinum L.)

    International Nuclear Information System (INIS)

    Effect of irradiation (0.005-0.20 kGy) and subsequent germination on trypsin inhibitor activity (TIA) and protein content of chickpea, was studied. The results revealed a significant linear relation (r = -0.981 to -0.992) between the loss of TIA and germination time, and the rate of TIA destruction increased with irradiation dose (p < 0.05). Maximum destruction (43.8%) of the TIA occurred on germination for 120 hr of 0.20 kGy sample (from 330.0 to 185.3 TIU/g). Initially protein content was 21.7% and the value significantly increased to maximum levels of 27.5% and 27.9% in distilled and tap water respectively during germination for 120 hr of 0.10 kGy sample (p < 0.05). Protein contents were not affected by irradiation

    Full Text Available The changes in the level of some inorganic constituents and the activities of some important enzyme systems in senescent leaves of chickpea (Cicer arietinum L. have been studied. In senescent leaves, a marked decline in the potassium and phosphorus contents was evident which was accompanied by the accumulation of calcium, silicon, chloride and manganese. Leaf senescence was accompanied by a great increase in hydrolytic processes, as revealed by the increase in the activities of acid phosphatase, alkaline phosphatase, ATPase, inorganic pyrophosphatase and 3-phosphoglycerate phosphatase. The activities of nitrogen metabolism enzymes, namely nitrate reductase, nitrite reductase, glutamine synthetase and alanine aminotransferase, and of photorespiratory enzymes -- phosphoglycolate phosphatase, glycolate oxidase and catalase, were lower in senescent leaves. Leaf senescence was further associated with an increase in the activities of peroxidase and polyphenol oxidase, a considerable depression in pyruvate kinase activity, and a slight elevation in aldolase activity.

  8. Chickpea and cowpea grain improvement using mutation and other advanced genetic techniques

    International Nuclear Information System (INIS)

    The use of genetic engineering methodologies in breeding programmes seems to be very promising to find new resistance-related genes present in other phyla, to clone and transfer them into plants; and, to shorten the time to obtain an improved genotype since only a single gene is involved in this process. The main ''bottle-neck'' to apply this scheme in chickpea and cowpea is the absence of a reliable protocol of regeneration and genetic transformation. In this frame, following some pilot experiments on these grain legumes to induce regeneration and gene transfer, we attempted to find a regeneration medium, assay the effect of different hormones on young tissues; and, to select the best procedures for transfer of genes into the plant genome

  9. Modulation in radiation-induced changes in peroxidase activity with gibberellic acid in seedling's growth in chickpea (Cicer arietinum L.)

    International Nuclear Information System (INIS)

    Changes in the effects of gamma irradiation (10 to 110 Kr) with gibberellic acid (GA/sub 3/) for peroxidase activity, in relation to early days of seedling's growth in Kabulic chickpea cultivar, Noor-91, were evaluated. Stimulation in peroxidase activity over control was recorded at all the irradiation treatments from 3rd to 8th day of seedling's development. Increase in peroxidase activity at 10 and 20 Kr was due to the increase in metabolic activity, while higher doses of gamma radiation account for the damaging action and production of peroxy radicals. However, stimulation in fresh weight was observed only at 10 Kr of gamma irradiation. Postmutagenic application of Ga/sub 3/ protect the seedlings from radiation injury, by increasing the peroxides activity, and increased the fresh weight of chickpea seedlings. (author)

    2013-08-01

    Full Text Available A pot experiment was conducted to study the effects of silicon (Si and/or potassium (K on plant growth, nitrogen uptake and N2-fixation in water stressed (FC1 and well watered (FC2 chickpea plants using 15N and 13C isotopes. Three fertilizer rates of Si (Si50, Si100 and Si200 and one fertilizer rate of K were used. For most of the growth parameters, it was found that Si either alone or in combination with K was more effective to alleviate water stress than K alone. Increasing soil water level from FC1 to FC2 often had a positive impact on values of almost all studied parameters. The Si100K+ (FC1 and Si50K+ (FC2 treatments gave high enough amounts of N2-fixation, higher dry matter production and greater nitrogen yield. The percent increments of total N2-fixed in the above mentioned treatments were 51 and 47% over their controls, respectively. On the other hand, increasing leave’s dry matter in response to the solely added Si (Si50K- and Si100K- is associated with lower Δ13C under both watering regimes. This may indicate that Si fertilization had a beneficial effect on water use efficiency (WUE. Hence, Δ13C could be an adequate indicator of WUE in response to the exogenous supply of silicon to chickpea plants. Our results highlight that Si is not only involved in amelioration of growth and in maintaining of water status but it can be also considered an important element for the symbiotic performance of chickpea plants. It can be concluded that the synergistic effect of silicon and potassium fertilization with adequate irrigation improves growth and nitrogen fixation in chickpea plants.

  12. Suitable gamma ray dose determination in order to induce genetic variation in kaboli chickpea (Cicer Arietinum L)

    International Nuclear Information System (INIS)

    In spite of chickpea's use in Iran and its ability of being replaced to adjust the shortage of protein in dietary habits, yield production is very low. One of the main reasons for chickpea's low yield production is its sensitiveness to some diseases, pest and environmental stresses. Genetic variation in chickpea is very low, because of its self pollination. In breeding programs, genetic variation plays an essential role so that the induction of genetic variation in plant population is very important for the plant breeders. The induced mutation through different kinds of mutagens is one of the important ways of genetic variation. In this research, first the sensitiveness of four cultivars (ILC.486, Philip86, Bivinich, Jam) were assessed to different gamma ray doses (100, 200, 300, 400 Gy). The results showed that with an increase in gamma ray dose, the growth rate of chickpea's genotypes decreases. In this respect, the decrease of growth rate has a linear relationship with the gamma ray dose and it is independent from the genotypes. The root length is more sensitive to gamma ray doses than its shoot, and it was observed that at the low doses the root growth decreases, comparing to the shoot growth. On the other hand, in high doses of gamma ray growth abrasion (Ageotropism, Albinism and etc.) were observed. Some traits variation (such as leaf shape, leaf size, leaf color, Albinism, etc.) were seen in M2 generation, and finally to continue the project, three doses of gamma ray (150,200,250) were selected for the next year

  13. Nodulation, dry matter production and N2 fixation by fababean and chickpea as affected by soil moisture and potassium fertilizer

    International Nuclear Information System (INIS)

    The impact of three rates of K-fertilizer (0, 75, and 150 kg K2O/ha)on nodulation, dry matter production and N2 fixation by fababean (Vicia faba L.) and chickpea (Cirer arietinum L.) was evaluated in a pot experiment. The plants were subjected to three soil moisture regimes (low, 45-50%; moderate, 55-60% and high 75-80% of field capacity). 15N-isotope dilution method was employed to evaluate N2 fixation using a non-fixing chickpea genotype as a reference crop. Water restriction drastically affected dry matter production, nodulation and N2 fixation by both plant species. The negative effect of water stress on %N2 fixed was more prominent in chickpea (11-58%) than in fababean (68-81%) under low and high % of field capacity, respectively. Plant species differed in their response to K-fertilizer as a mean to enhance growth and overcome the stress conditions. The higher level of K fertilizer increased both dry matter production and total N2 fixed in fababean, but did not have any impact on chickpea. %N2 fixed, however, appeared to be unaffected by K fertilizer as a mean of alleviating drought stress in both plant species. Therefore, it appears that, under the experimental conditions, the beneficial effect of potassium on water-stressed fababean resulted from stimulation the growth rather than improving the N2-fixation efficiency. However, under well-watered plants, a high requirement of the symbiotic system to potassium is needed to ensure and optimal growth and N2-fixation. (author)

    2016-05-01

    To understand raffinose family oligosaccharides (RFO) metabolism in chickpea (Cicer arietinum L.) seeds, RFO accumulation and corresponding biosynthetic enzymes activities were determined during seed development of chickpea genotypes with contrasting RFO concentrations. RFO concentration in mature seeds was found as a facilitator rather than a regulating step of seed germination. In mature seeds, raffinose concentrations ranged from 0.38 to 0.68 and 0.75 to 0.99 g/100 g, whereas stachyose concentrations varied from 0.79 to 1.26 and 1.70 to 1.87 g/100 g indicating significant differences between low and high RFO genotypes, respectively. Chickpea genotypes with high RFO concentration accumulated higher concentrations of myo-inositol and sucrose during early seed developmental stages suggesting that initial substrate concentrations may influence RFO concentration in mature seeds. High RFO genotypes showed about two to three-fold higher activity for all RFO biosynthetic enzymes compared to those with low RFO concentrations. RFO biosynthetic enzymes activities correspond with accumulation of individual RFO during seed development. PMID:26953100

    Full Text Available Problem statement: Mexico is the third largest producer and exporter of chickpea (Cicer arietinum, with the states of Sinaloa and Sonora accounting for 70 and 20% of Mexicos production, respectively. The most damaging disease affecting this species is caused by Fusarium oxysporum f.sp. Ciceris (FOC, which causes losses of up to 60% in Sonora. The objective of this study was to isolate and characterize the phenotype and genetics of FOC collected from affected chickpea plants in northwestern Mexico and to identify the abiotic factors that allow it to develop. Approach: Sampling focused on affected plants from 12 crops in Sonora and Sinaloa. Based on 355 isolated strains, using Polymerase Chain Reaction (PCR 161 were positive for FOC. Results: Of the 161 strains, 91 were identified as races previously recorded for the Americas: Yellowing (R0 (41%, R1B/C (15% and wilting (R5 (14% and R6 (28% reflecting the symptoms observed in the areas sampled. The other 70 isolates could be nonpathogenic, or could be races yet to be recorded for the Americas. Conclusion: Morphological variability in FOC was high in the main chickpea producing regions in northwestern Mexico and was not a function of the physical and chemical properties of the soil, nor of the geographic location of the cropfields. This is the first report of races of FOC in Mexico.

    Full Text Available Botrytis gray mold (BGM caused by Botrytis cinerea Pers. Ex. Fr. is an extremely devastating disease of chickpea (Cicer arietinum L. and has a regional as well as an international perspective. Unfortunately, nonchemical methods for its control are weak and ineffective. In order to identify an effective control measure, six fungicides with different modes of action were evaluated on a BGM susceptible chickpea variety BARIchhola-1 at a high BGM incidence location (Madaripur in Bangladesh for three years (2008, 2009, and 2010. Among the six fungicides tested, one was protectant [Vondozeb 42SC, a.i. mancozeb (0.2%], two systemic [Bavistin 50 WP, a.i. carbendazim (0.2%, and Protaf 250EC, propiconazole (0.05%], and three combination formulations [Acrobat MZ690, dimethomorph 9% + mancozeb 60%, (0.2%; Secure 600 WG, phenomadone + mancozeb (0.2%; and Companion, mancozeb 63% + carbendazim 12% (0.2%]. The results showed superiority of combination formulations involving both protectant and systemic fungicides over the sole application of either fungicide separately. Among the combination fungicides, Companion was most effective, resulting in the lowest disease severity (3.33 score on 1–9 scale and the highest increase (38% of grain yield in chickpea. Therefore, this product could be preferred over the sole application of either solo protectant or systemic fungicides to reduce yield losses and avoid fungicide resistance.

    2010-07-01

    Physiological variability was studied in 10 isolates of Botrytis cinerea causing botrytis gray mold of chickpea, collected from diverse agro climatic areas in Bangladesh. The optimum temperature and pH for the best mycelial radial growth of B. cinerea were 20 degree centigrade and 4.5, respectively. The mycelial radial growth increased with the temperature up to 20 degree centigrade thereafter it decreased gradually up to 30 degree centigrade and no growth was observed at 35 degree centigrade. Chickpea dextrose agar (CDA) medium supported the highest mycelial radial growth (79.17 mm). The quickest (in 5 days) sclerotia initiation was recorded on chickpea destrose agar and lentil dextrose agar (LDA) culture media while the highest number of spores (2.5104 mL{sup -}1) were recorded on LDA medium. The antagonist Trichoderma harzianum was found to be a good bio-control agent against B. cinerea. Among the seven fungicides Bavistin 50 WP (Carbendazim), CP-Zim 50 WP (Carbendazim), Sunphanate 70 WP (Thiophanate methyl) and Rovral 50 WP (Iprodione) were the most effective to inhibit the mycelial radial growth of B. cinerea at 500 mg L{sup -}1 concentration.

    To our knowledge, this is the first report on the use of factor analysis in determining characters for yield selection in chickpea (Cicer arietinum L.). The present investigation was undertaken to evaluate yield criteria in chickpea using phenotypic correlations and factor analysis. Factor 1 composed of biological yield, reaction to ascochyta blight (Ascochyta rabiei (Pass.) Labr.), plant height, grain yield and harvest index. Factor 2 consisted of branches and pods per plant. Factor 3 encompassed of only the grain weight. The total factors explained 92.9% of the total variance caused in the characters. The grain yield was positively and statistically significant correlated with biological yield, harvest index, plant height, branches and pods per plant, while it was negatively and statistically significant related with reaction to ascochyta blight and grain weight. Biological yield, harvest index, plant height and reaction to ascochyta blight instead of many selection criteria should previously be evaluated in selection to increase the grain yield in chickpea breeding programs. Pods per plant should be handed together with and branches per plant. Apart from the other selection criteria, the grain weight should solely be evaluated to select large grained genotypes.

    The present study used a whole-genome, NGS resequencing-based mQTL-seq (multiple QTL-seq) strategy in two inter-specific mapping populations (Pusa 1103 × ILWC 46 and Pusa 256 × ILWC 46) to scan the major genomic region(s) underlying QTL(s) governing pod number trait in chickpea. Essentially, the whole-genome resequencing of low and high pod number-containing parental accessions and homozygous individuals (constituting bulks) from each of these two mapping populations discovered >8 million high-quality homozygous SNPs with respect to the reference kabuli chickpea. The functional significance of the physically mapped SNPs was apparent from the identified 2,264 non-synonymous and 23,550 regulatory SNPs, with 8-10% of these SNPs-carrying genes corresponding to transcription factors and disease resistance-related proteins. The utilization of these mined SNPs in Δ (SNP index)-led QTL-seq analysis and their correlation between two mapping populations based on mQTL-seq, narrowed down two (Caq(a)PN4.1: 867.8 kb and Caq(a)PN4.2: 1.8 Mb) major genomic regions harbouring robust pod number QTLs into the high-resolution short QTL intervals (Caq(b)PN4.1: 637.5 kb and Caq(b)PN4.2: 1.28 Mb) on chickpea chromosome 4. The integration of mQTL-seq-derived one novel robust QTL with QTL region-specific association analysis delineated the regulatory (C/T) and coding (C/A) SNPs-containing one pentatricopeptide repeat (PPR) gene at a major QTL region regulating pod number in chickpea. This target gene exhibited anther, mature pollen and pod-specific expression, including pronounced higher up-regulated (∼3.5-folds) transcript expression in high pod number-containing parental accessions and homozygous individuals of two mapping populations especially during pollen and pod development. The proposed mQTL-seq-driven combinatorial strategy has profound efficacy in rapid genome-wide scanning of potential candidate gene(s) underlying trait-associated high-resolution robust QTL(s), thereby

    Full Text Available Greenhouse pot experiments were carried out in 2004 to check if there are any variations available for carbon isotope discrimination (d13C, to investigate the relationship between d13C and transpiration efficiency (TE, and to ascertain the possibility of using d13C as a surrogate for TE measurements. Ten chickpea genotypes (Annigeri, ICC 10448, ICC 13219, ICC 14199, ICC 1882, ICC 283, ICC 4958, ICC 5337, ICC 5680 and ICC 8261 with contrasting growth duration, type (desi or kabuli, growth habit and root system were used. In the well-watered pots (control, the water lost in a day was added back, whereas in the water stress-imposed pots the water, which is equivalent to 70-90% of daily transpiration, was given to avoid the rapid build up of soil water stress. There were significant differences in d13C among the 10 genotypes and the d13C in stress condition was significantly higher than that in the well-wateredcontrol. Genotype ICC 5337 showed the highest d13C (-26.0% in the stress condition. ICC 4958, a well-known drought-resistant cultivar, had superior d13C value than the other genotypes. ICC 4958 ranked second (-27.2% under stress condition and the first (-28.4% in the well-watered control condition. The genotype by irrigation (G x I interaction was significant for d13C. Among 10 genotypes, a significant difference in TE was observed in both irrigated and stress conditions. Genotype ICC 5337 showed the highest TE irrespective of irrigations of 3.9 g/kg under stress and 2.8 g/kg under well-watered control. The TE under stress was significantly higher than the TE under the control. There was a significant correlation in TE between the stress and control conditions and there was no G x I interaction observed. A significant positive correlation between d13C and TE was observed under the stress condition. However, no significant correlation was observed between d13C and TE when the plants were grown under well-watered conditions. The results shows

  3. Remobilisation of carbon and nitrogen supports seed filling in chickpea subjected to water deficit

    International Nuclear Information System (INIS)

    In the Mediterranean-type environment of south-western Australia, pod filling of chickpea occurs when net photosynthesis and nitrogen fixation is low as a result of the onset of terminal drought. Remobilization of carbon (C) and nitrogen (N) from vegetative parts to developing seed may be an important alternative source of C and N for seed filling. The contribution of stored pre-podding C and N to seed filling was studied by labelling the vegetative tissues with the stable isotopes, 13C and 15N, prior to podding and following their subsequent movement to the seed. In ICCV88201, an advanced desi breeding line, 9% of the C and 67% of the N in the seed were derived from pre-podding C and N in well-watered plants compared with 13% of the seed C and 88% of the seed N in water-stressed plants. Furthermore, the contribution of pre-podding C and N was higher for earlier set compared with later set seeds. Pre-podding C and N were derived predominantly from the leaves with relatively little from the stems, roots, and pod walls. Genotypic variation in remobilization ability was identified in contrasting desi (Tyson) and kabuli (Kaniva) cultivars. In well-watered Tyson, 9% of the seed C and 85% of the seed N were remobilised from vegetative tissues compared with 7% of the seed C and 62% of seed N in well-watered Kaniva. Water deficit decreased the amount of C remobilized by 3% in Tyson compared with 66% in Kaniva, whereas the total amount of N remobilized was decreased by 11% in Tyson and 48% in Kaniva. This was related to the maintenance of greater sink strength in Tyson, in which the number of filled pods was reduced by 66% in stressed plants compared with a 91% decrease in Kaniva. This indicates that better drought tolerance in desi genotypes is partly a consequence of better remobilization and higher pod number. These studies show that C and N assimilated prior to podding can supplement the supply of current assimilates to the filling seed in both well-watered and water

    Pulses are known to be nutritious foods but are susceptible to oxidation due to the reaction of lipoxygenase (LOX) with linolenic and linoleic acids which can lead to off flavors caused by the formation of volatile organic compounds (VOCs). Infrared micronization at 130 and 150 °C was investigated as a heat treatment to determine its effect on LOX activity and VOCs of chickpea and green lentil flour. The pulse flours were added to low-fat beef burgers at 6% and measured for consumer acceptability and physicochemical properties. Micronization at 130 °C significantly decreased LOX activity for both flours. The lentil flour micronized at 150 °C showed a further significant decrease in LOX activity similar to that of the chickpea flour at 150 °C. The lowering of VOCs was accomplished more successfully with micronization at 130 °C for chickpea flour while micronization at 150 °C for the green lentil flour was more effective. Micronization minimally affected the characteristic fatty acid content in each flour but significantly increased omega-3 and n-6 fatty acids at 150 °C in burgers with lentil and chickpea flours, respectively. Burgers with green lentil flour micronized at 130 and 150 °C, and chickpea flour micronized at 150 °C were positively associated with acceptability. Micronization did not affect the shear force and cooking losses of the burgers made with both flours. Formulation of low-fat beef burgers containing 6% micronized gluten-free binder made from lentil and chickpea flour is possible based on favorable results for physicochemical properties and consumer acceptability.

    Full Text Available The plant-specific NAC transcription factors (TFs play important roles in regulation of diverse biological processes, including development, growth, cell division and responses to environmental stimuli. In this study, we identified the members of the NAC TF family of chickpea (Cicer arietinum and assess their expression profiles during plant development and under dehydration and abscisic acid (ABA treatments in a systematic manner. Seventy-one CaNAC genes were detected from the chickpea genome, including 8 membrane-bound members of which many might be involved in dehydration responses as judged from published literature. Phylogenetic analysis of the chickpea and well-known stress-related Arabidopsis and rice NACs enabled us to predict several putative stress-related CaNACs. By exploring available transcriptome data, we provided a comprehensive expression atlas of CaNACs in various tissues at different developmental stages. With the highest interest in dehydration responses, we examined the expression of the predicted stress-related and membrane-bound CaNACs in roots and leaves of chickpea seedlings, subjected to well-watered (control, dehydration and ABA treatments, using real-time quantitative PCR (RT-qPCR. Nine-teen of the 23 CaNACs examined were found to be dehydration-responsive in chickpea roots and/or leaves in either ABA-dependent or -independent pathway. Our results have provided a solid foundation for selection of promising tissue-specific and/or dehydration-responsive CaNAC candidates for detailed in planta functional analyses, leading to development of transgenic chickpea varieties with improved productivity under drought.

  7. Natural incidence of aflatoxins, mycological profile and molecular characterization of aflatoxigenic strains in chickpea flour

    International Nuclear Information System (INIS)

    The mycological profile of retail chickpea flour (locall called Baisan), sold in the markets in the Rawalpindi district was studied. All the samples were tested for the contamination with aflatoxins. A total of 13 fungal species isolated from the flour and out of which, Aspergillus flavus was recorded the most common species (100%), followed by Rhizopus oryzea (50%), Aspergillus niger (40%), Penicilium digitatum (30%), Cladosporium cladosporoides, Fusarium oxysporium, Mucor recemosus, M. petrinsularis and Rhizopus arrhizus (20% each), Aspergillus oryzea, Botritus cinerea, Mucor circineloides and Penicillium sp. (10% each). Aflatoxin B1 was found in only 20% of the samples ranging from 3.03-4.24ppb. The molecular characterization was carried out by using PCR using simple sequence repeats (SSR) primers. The SSR amplification pattern clearly showed the genetic variability among the 10 strains of A. flavus. A dendrogram was generated through MVSP software program. Genotype AF04 was most diverse among all genotypes. The similarity value was ranged between 0.538 (53.8%)-0.938 (93.8%). (author)

  8. Mutation induction in mungbean, blackgram, chickpea and lentil using chemical mutagens

    International Nuclear Information System (INIS)

    Full text: Grain legumes cultivated in Bangladesh have narrow genetic bases. Seeds of four species were treated with sodium azide (NaN3) and EMS to create genetic variability. Phenotypically deviant types were selected in M2. The mungbean mutants were synchronous, early, bushy, erect and disease tolerant. Maximum frequency of variants occurred in the treatment with 0.75 mM of NaN3. The blackgram mutants were dwarf, bushy, trailing, synchronous and prolific podded. 1.0 mM NaN3 and 2% EMS concentrations produced the highest frequency of mutants. The chickpea mutants included broad-leaved, white flowered, erect, dwarf, bushy, early and chlorophyll-deficient types. White-flower mutants were reasonably free from wilt disease. The 0.4 mM concentration of NaN3 produced the highest frequency of mutants. In lentil, late flowering mutants were predominant. Some plants with increased number of pods were selected. Maximum frequency of mutants were obtained from 0.50 mM concentration of NaN3. (author)

  9. Response of rainfed chickpea (cicer arietnum L.) to tween row spatial arrangement at multiple densities

    International Nuclear Information System (INIS)

    Plant density and arrangement are important factors affecting rainfed chickpea yield. A field experiment was conducted under the Eastern Mediterranean conditions for two consecutive growing seasons (2009-2010 and 2010-2011) to evaluate the effects of plant density (20, 25, 35 and 55 plants per m 2) and spatial configuration (conventional single 36-cm row width vs 18-cm twin rows spaced 72-cm between paired-rows). The experiment was laid out in a randomized complete block design in a factorial arrangement with three replications. Light interception (LI) and leaf area index (LAI) were significantly affected by plant density. Twin-row arrangement had higher light interception efficiency (LIE) than the single-row. Plants grown in the higher plant densities had greater LAI and LI; however, they had inefficient use of incident solar radiation. The number of primary branches was significantly affected by both planting patterns and plant densities, but the number of secondary branches was significantly affected only by the plant densities. The number of pods and seeds/plant decreased with the increasing plant density. The highest seed weight/plant was recorded at the lowest density (20 plants/m2) while the lowest one was recorded at the highest plant density (55 plants/m2). Seed weight and harvest index in the twin row were significantly higher in tween row than in the single row. (author)

    The impact of enzymatic hydrolysis by Alcalase on the conformational and functional properties of chickpea protein isolate (CPI) was investigated. The physicochemical, interfacial tension and surface characteristics of CPI and their hydrolysates (CPH) according to the degree of hydrolysis (DH) were also determined. These parameters were then related to the changes in the emulsification activity (EAI) and stability (ESI). The enzymatic hydrolysis was found to improve protein recovery and solubility, leading to a reduction in the molecular weight bands with a concomitant increase in the intensity and appearance of protein bands having apparent molecular mass below 20 kDa. The interfacial tension decreased from ∼ 66.5 mN m(-1) for CPI to ∼ 59.1 m Nm(-1) for CPH. A similar trend was observed for the surface charge which declined from -27.55 mV to -16.4 mV for the CPI and CPH, respectively. These changes were found to have a detrimental effect on the EAI and ESI values. PMID:25977033

    The present study aimed to characterize and investigate the functional and angiotensin-I converting enzyme (ACE) inhibition activities of chickpea water-soluble polysaccharides (CPWSP). Physico-chemical characteristics were determined by nuclear magnetic resonance spectroscopy (NMR), Fourier transform-infrared spectroscopy (FT-IR) analysis, and X-ray diffractometry (XRD). Functional properties (water holding capacity: WHC, water solubility index: WSI, swelling capacity: SC, oil holding capacity: OHC, foaming, and emulsion properties) and ACE activities were also investigated using well-established procedures. The FT-IR spectra obtained for the CPWSP revealed two significant peaks, at about 3500 and 500 cm(-1), which corresponded to the carbohydrate region and were characteristic of polysaccharides. All spectra showed the presence of a broad absorption between 1500 and 670 cm(-1), which could be attributed to CH, CO, and OH bands in the polysaccharides. CPWSP had an XRD pattern that was typical for a semi-crystalline polymer with a major crystalline reflection at 19.6 °C. They also displayed important techno-functional properties (SWC, WSI, WHC, and OHC) that can be modulated according to temperature. The CPWSP were also noted to display good anti-hypertensive activities. Overall, the results indicate that CPWSP have attractive chemical, biological, and functional properties that make them potential promising candidates for application as alternative additives in various food, cosmetic, and pharmaceutical preparations.

    In this study, starch isolated from chickpea was exposed to gamma-irradiation at 0, 4, 8 and 12kGy doses. The irradiated starches were evaluated for their physicochemical, morphological and pasting properties. The results revealed significant (p≤0.05) reduction in apparent amylose content, swelling power, turbidity, syneresis, L (lightness) value, and pasting parameters whereas solubility and b (yellowness) value increased with increase in irradiation dose. X-ray diffraction showed C-type of crystallographic pattern. Relative crystallinity (RC) of irradiated starches was different at different irradiation doses. Prominent changes were recorded in the FT-IR spectra of irradiated starch samples with respect to intensity and shifting of major bands in specific regions. Analysis of O - H and C - H stretches, bending mode of water and glycoside bonds of irradiated starches revealed marked decrease in their absorbance intensities. Scanning electron microscopy revealed cracking and clumping of starch granules at elevated doses of gamma-irradiation. Radiation doses were negatively correlated to swelling power, pasting parameters (peak viscosity, hold viscosity, final viscosity, setback viscosity and pasting temperature), turbidity, syneresis and apparent amylose content except solubility.

    Adaptation to plant allelochemicals is a crucial aspect of herbivore chemical ecology. To understand an insect ecology, we studied an effect of nonhost Cassia tora seed-based diet (Ct) on growth, development, and molecular responses in Helicoverpa armigera. We employed a comparative approach to investigate the proteomic differences in gut, hemolymph, and frass of H. armigera reared on a normal (chickpea seed-based, Cp) and Ct diet. In this study, a total of 46 proteins were identified by nano-LC-MS(E). Among them, 17 proteins were up-regulated and 29 proteins were down-regulated when larvae were exposed to the Ct diet. Database searches combined with GO analysis revealed that gut proteases engrossed in digestion, proteins crucial for immunity, adaptive responses to stress, and detoxification were down-regulated in the Ct fed larvae. Proteins identified in H. armigera hemolymph were found to be involved in defense mechanisms. Moreover, proteins found in frass of the Ct fed larvae were observed to participate in energy metabolism. Biochemical and quantitative real-time PCR analysis of selected candidate proteins showed differential gene expression patterns and corroborated with the proteomic data. Our results suggest that the Ct diet could alter expression of proteins related to digestion, absorption of nutrients, adaptation, defense mechanisms, and energy metabolism in H. armigera.

    Rhizobacteria promote and have beneficial effects on plant growth, making them useful to agriculture. Nevertheless, the rhizosphere of the chickpea plant has not been extensively examined. The aim of the present study was to select indole-3-acetic acid (IAA) producing rhizobacteria from the rhizosphere of chickpea plants for their potential use as biofertilizers. After obtaining a collection of 864 bacterial isolates, we performed a screen using the Salkowski reaction for the presence of auxin compounds (such as IAA) in bacterial Luria-Bertani supernatant (BLBS). Our results demonstrate that the Salkowski reaction has a greater specificity for detecting IAA than other tested auxins. Ten bacterial isolates displaying a wide range of auxin accumulation were selected, producing IAA levels of 5 to 90 μmol/L (according to the Salkowski reaction). Bacterial isolates were identified on the basis of 16S rDNA partial sequences: 9 isolates belonged to Enterobacter, and 1 isolate was classified as Serratia. The effect of BLBS on root morphology was evaluated in Arabidopsis thaliana. IAA production by rhizobacteria was confirmed by means of a DR5::GFP construct that is responsive to IAA, and also by HPLC-GC/MS. Finally, we observed that IAA secreted by rhizobacteria (i) modified the root architecture of A. thaliana, (ii) caused an increase in chickpea root biomass, and (iii) activated the green fluorescent protein (GFP) reporter gene driven by the DR5 promoter. These findings provide evidence that these novel bacterial isolates may be considered as putative plant-growth-promoting rhizobacteria modifying root architecture and increasing root biomass.

  17. Biological Nitrogen Fixation and Microbial Biomass N in the Rhizosphere of Chickpea as Estimated by 15N Isotope Dilution Technique

    International Nuclear Information System (INIS)

    Pot experiment was carried out with chickpea that cultivated in virgin sandy soil and inoculated with Rhizobium (Rh), mycorrhizea (VAM) and mixture of both. The objective of this work is the estimation of biological nitrogen fixation (BNF) and microbial biomass N (MBN) contribution as affected by inoculation and N and P fertilizers levels under chickpea plants. Nitrogen gained from air (Ndf A) was determined using 15N isotope dilution technique, while the MBN was detected through the fumigation-extraction method. Nitrogen and phosphorus fertilizers were applied at three levels, 0; 10 ppm N and 3.3 ppm P and 20 ppm Nand 6.6 ppm P in the form of (15NH4)2SO4 and super-phosphate, respectively. The effect of inoculation and chemical fertilizers on dry matter (DM), N and P uptake (shoot and grain), BNF and MBN were traced. The obtained data revealed that the highest DM and N uptake by chickpea shoot were recorded with the dual inoculation (Rh + VAM) at the moderate level of N and P fertilizers, while the highest DM, N and P uptake by grain were recorded with Rh solely at the same rate of fertilizers. It was clear that inoculation with Rh either alone or in combination with VAM substituted considerable amounts of N via BNF process. In this respect, dual inoculation is still superior over single inoculation. Percentages of N2-fixed was ranged from 45% to 73% in shoot while it was 27% to 69% in grain according to inoculation and fertilization treatments. Fixed N utilized by shoot was positively affected by increasing the N fertilizer rate while that derived by grain was not affected. The fluctuation in the soil microbial biomass N did not gave us a chance to recognize, exactly, the impact of inoculation and/or fertilization levels. (Authors)

    Cover crops improve the sustainability and quality of both natural system and agro ecosystem. In Gumara-Maksegnit watershed which is located in Lake Tana basin, farmers usually use fallow during the rainy season for the preceding chickpea production system. The fallowing period can lead to soil erosion and nutrient losses. A field experiment was conducted during growing seasons 2014 and 2015 to evaluate the effect of cover crops on runoff, soil loss, soil chemical properties and yield of chickpea in North Gondar, Ethiopia. The plot experiment contained four treatments arranged in Randomized Complete Block Design with three replications: 1) Control plot (Farmers' practice: fallowing- without cover crop), 2) Chickpea planted with Di-ammonium phosphate (DAP) fertilizer with 46 k ha-1 P2O5 and 23 k ha-1 nitrogen after harvesting vetch cover crop, 3) Chick pea planted with vetch cover crop incorporated with the soil as green manure without fertilizer, 4) Chick pea planted with vetch cover crop and incorporated with the soil as green manure and with 23 k ha-1 P2O5 and 12.5 k ha-1 nitrogen. Each plot with an area of 36 m² was equipped with a runoff monitoring system. Vetch (Vicia sativa L.) was planted as cover crop at the onset of the rain in June and used as green manure. The results of the experiment showed statistically significant (P 0.05) on average plant height, average number of branches and hundred seed weight. Similarly, the results indicated that cover crop has a clear impact on runoff volume and sediment loss. Plots with vetch cover crop reduce the average runoff by 65% and the average soil loss decreased from 15.7 in the bare land plot to 8.6 t ha-1 with plots covered by vetch. In general, this result reveales that the cover crops, especially vetch, can be used to improve chickpea grain yield in addition to reduce soil erosion in the watershed.

  1. Mutation breeding for resistance to downy mildew and ergot in Pennisetum and to Ascochyta in chickpea

    International Nuclear Information System (INIS)

    The mutational rectification of the susceptible male steriles of otherwise food yield, and the pollen parents in pearl millet of the released hybrids has been completed successfully. The reconstituted hybrids were tested in National Coordination trials and one of them (NHB5) has been released for All-India cultivation during 1975. They were also tested in more than 2000 trials all over India in farmers' fields. The yield level of the released hybrid (NHB5) based on trials during the past four seasons is 19.2 Q/ha in 232 trials as compared to 14.5 Q/ha of HB-3 (old) based on 221 trials. Biochemical analysis of seedlings of the mutant male steriles resistant to downy mildew and their normal counterparts indicated larger peroxidase activity of high electrophoretic mobility in the resistant ones. In the trials of the reconstituted hybrids along with their normal counterparts the new hybrids proved at least as good in yield even in the absence of the disease in virulent form. Mutational rectification of the male sterile lines and pollen parents could be shown to provide resistance with wide adaptation. Nearly 400 tons of hybrid seed from mutational rectified parents has replaced the earlier hybrids and will cover an area of 80,000 ha in 1976 alone. The low incidence of downy mildew in the male sterile developed from the mutation breeding is likely to be horizontal resistance of greater stability. The M2 generation of chickpea showed appropriate skewed distribution of means for several of the 17 characters studied, including flowering time and yield

  2. Improvement of Chickpea Growth and Biological N Fixation under Water Salinity Stress

    International Nuclear Information System (INIS)

    This work had been carried out under greenhouse conditions of IAM-Bari, aimed at evaluating the effects of water and soil salinity on growth, yield and nitrogen fixation by chickpea plants inoculated with selected Rhizobium strains. Isotope dilution approach (15N) was applied for quantification of biological N fixation and portions derived from fertilizer and soil (Ndff and Ndfs, respectively). Number of pods was decreased gradually with increasing water salinity levels. High levels of salinity negatively affected shoot, root dry matter, seed yield and N accumulated in shoots and roots. A slight difference in seed N was noticed between fresh water and 9 dS/m treatments. Nitrogen derived from fertilizer by shoots was slightly increased with 3, 6 and 9 dS/m treatments, while they were notably higher than the fresh water control. More than 80% and 70% of N accumulated in shoots and seeds, respectively were derived from fixation. Portions of N2-fixed in shoots was decreased with the level of 3 dS/m as compared to the fresh water, then tended to increase with both 6 and 9 dS/m treatments. Stability of %Ndfa with increasing salinity was noticed with seeds-N. Soil-N came next as a fraction of nitrogen demand, where it increased with increasing water salinity levels. Under adverse conditions of salinity, the plants offered some of their N requirements from the other two N sources. Application of the suitable Rhizobium bacteria strains could be profits for both of the plant growth and soil fertility via N2 fixation. (Authors)

    In this study, optimization of energy consumption and environmental impacts of chickpea production was conducted using data envelopment analysis (DEA and multi objective genetic algorithm (MOGA techniques. Data were collected from 110 chickpea production enterprises using a face to face questionnaire in the cropping season of 2014–2015. The results of optimization revealed that, when applying MOGA, optimum energy requirement for chickpea production was significantly lower compared to application of DEA technique; so that, total energy requirement in optimum situation was found to be 31511.72 and 27570.61 MJ ha−1 by using DEA and MOGA techniques, respectively; showing a reduction by 5.11% and 17% relative to current situation of energy consumption. Optimization of environmental impacts by application of MOGA resulted in reduction of acidification potential (ACP, eutrophication potential (EUP, global warming potential (GWP, human toxicity potential (HTP and terrestrial ecotoxicity potential (TEP by 29%, 23%, 10%, 6% and 36%, respectively. MOGA was capable of reducing the energy consumption from machinery, farmyard manure (FYM diesel fuel and nitrogen fertilizer (the mostly contributed inputs to the environmental emissions by 59%, 28.5%, 24.58% and 11.24%, respectively. Overall, the MOGA technique showed a superior performance relative to DEA approach for optimizing energy inputs and reducing environmental impacts of chickpea production system.

    A combination of two approaches, namely QTL analysis and gene enrichment analysis were used to identify candidate genes in the “QTL-hotspot” region for drought tolerance present on the Ca4 pseudomolecule in chickpea. In the first approach, a high-density bin map was developed using 53,223 single nucleotide polymorphisms (SNPs) identified in the recombinant inbred line (RIL) population of ICC 4958 (drought tolerant) and ICC 1882 (drought sensitive) cross. QTL analysis using recombination bins as markers along with the phenotyping data for 17 drought tolerance related traits obtained over 1–5 seasons and 1–5 locations split the “QTL-hotspot” region into two subregions namely “QTL-hotspot_a” (15 genes) and “QTL-hotspot_b” (11 genes). In the second approach, gene enrichment analysis using significant marker trait associations based on SNPs from the Ca4 pseudomolecule with the above mentioned phenotyping data, and the candidate genes from the refined “QTL-hotspot” region showed enrichment for 23 genes. Twelve genes were found common in both approaches. Functional validation using quantitative real-time PCR (qRT-PCR) indicated four promising candidate genes having functional implications on the effect of “QTL-hotspot” for drought tolerance in chickpea.

  8. Potential of recycling gamma-irradiated sewage sludge for use as a fertilizer: a study on chickpea (Cicer arietinum)

    International Nuclear Information System (INIS)

    The effects of gamma-irradiated sludge on the growth and yield of chickpea (Cicer arietinum) in pot cultures have been studied. Compared to plants grown only in soil, root length, fresh weight and dry weight of plants grown in soil supplemented with unirradiated sludge were found to be significantly reduced. This inhibition in growth was found to be nullified when plants were grown in soil supplemented with gamma-irradiated sludge, suggesting that gamma radiation induced inactivation of toxic substance(s) in sludge. The protein content of plants grown in soil supplemented with irradiated sludge was also found to be significantly increased compared to those grown with unirradiated or no sludge, after 45 days. There was no significant effect of gamma irradiated sludge on shoot length, total soluble sugars, starch content and yield of chickpea plants. The results obtained suggest that the sludge tested, and obtained from the digester of a conventional domestic sewage treatment plant, is inhibitory to several growth parameters. Gamma irradiation of sewage resulted in removal of this inhibition. This suggests a possibility of beneficial and safe recycling of gamma-irradiated sludge for agricultural uses. (author)

  9. Phospholipid mediated activation of calcium dependent protein kinase 1 (CaCDPK1 from chickpea: a new paradigm of regulation.

    Ajay Kumar Dixit

    Full Text Available Phospholipids, the major structural components of membranes, can also have functions in regulating signaling pathways in plants under biotic and abiotic stress. The effects of adding phospholipids on the activity of stress-induced calcium dependent protein kinase (CaCDPK1 from chickpea are reported here. Both autophosphorylation as well as phosphorylation of the added substrate were enhanced specifically by phosphatidylcholine and to a lesser extent by phosphatidic acid, but not by phosphatidylethanolamine. Diacylgylerol, the neutral lipid known to activate mammalian PKC, stimulated CaCDPK1 but at higher concentrations. Increase in V(max of the enzyme activity by these phospholipids significantly decreased the K(m indicating that phospholipids enhance the affinity towards its substrate. In the absence of calcium, addition of phospholipids had no effect on the negligible activity of the enzyme. Intrinsic fluorescence intensity of the CaCDPK1 protein was quenched on adding PA and PC. Higher binding affinity was found with PC (K(½ = 114 nM compared to PA (K(½ = 335 nM. We also found that the concentration of PA increased in chickpea plants under salt stress. The stimulation by PA and PC suggests regulation of CaCDPK1 by these phospholipids during stress response.

  11. effect of two rock phosphates and inoculation with VA mycorrhizae and phosphate solubilizing bacteria on the chickpea-rhizobium symbiosis

    International Nuclear Information System (INIS)

    A pot experiment was conducted tracing the effect of two types of phosphorus applied at different rates on the release of nitrogen from fertilizer and its impact on biological nitrogen fixation . chickpea (Cicer Arietinum c v. Cicer 36-ICARDA) was inoculated with peat-based inoculum of phosphorin (Bacillus Megatherium phosphate solubilizing bacteria), Mycorrhizae (VAM) and a mixture of phosphorin and VAM. three types of P fertilizer, i.e.superphosphate, rock P1 (Safaga) and rock P2 (Abou-Trtour) were applied at rate of 25 and 50 mg Pkg-1 soil in the presence or absence of inoculum. labelled ammonium sulfate with 15N 10% atom excess was applied at rates of 15 and 30 mg N kg-1 soil for chickpea and barley (reference crop) respectively . Addition of phosphorus fertilizers, especially at the high rates, positively affected the growth and dry weight as compared to the unfertilized control. infections with VAM mixed with phosphorin under low level of rock P (Abou-tarour) gave the highest values of dry weight and N and P uptake when compared with both superphosphate-P source and control. biological N2 fixed was higher in dual inoculation treatments (i.e.phosphorin +VAM) than those receiving a single inoculum. the percentages of N2-fixed ranged from 24 to 53 according to inoculation treatments, P sources and levels

  12. Nitrogen assimilation and partitioning in rainfed grown chickpea (cicer artietinum L.) at various growth stages using 15N methodology. Final report

    International Nuclear Information System (INIS)

    A field experiment was conducted to asses the sources of N(N2 fixation, soil and fertilizer), N and P partitioning and mobilization in rainfed grown chickpea at various growth stages using 15 N technique. The A-value method, involving the application of 20 and 100 Kg N ha-1 of 15 N labelled ammonium sulphate to chickpea and wheat as a reference crop respectively used to determine the relative contribution of N for these sources. Dry matter, N and P content in shoots, roots and nodules declined rapidly after flowering. Whereas, those of pods showed considerable increases. Soil water content - as measured by neutron scattering technique - decreased severely beyond flowering. Furthermore, the crop was exposed to heat stress at pod-filling which caused a decline in N2 fixation and affected the distribution of both N and P in the plant. The peak of N2 fixation occurred between bud flower initiation and maximum flowering. It was 3 Kg N ha-1 day-1 and 41 Kg N ha-1 per growth period. N2 fixation rate peaked at flowering and declined sharply thereafter during pod-filling. Such decline was a result of changes in source-sink relationships, resulting in a greater supply of carbohydrate and phosphorus to the developing pods and a reduced supply to nodules which showed considerable senescence following flowering. There was a net mobilization of N and P from shoots and roots to developing pods beyond flowering which amounted about 81% and 70% of N and P in pods respectively. At physiological maturity, chickpea had accumulated 103 Kg N ha-1, 60% of which was derived from fixation, 35% from soil and 5% from fertilizer. After seed removal, chickpea led to a non significant residual N in soil. Methods to improve N2 fixation in rainfed grown chickpeas were discussed. (author). 38 refs., 7 tabs., 6 figs

    Ana Paço

    Full Text Available The ClpB chaperone is known to be involved in bacterial stress response. Moreover, recent studies suggest that this protein has also a role in the chickpea-rhizobia symbiosis. In order to improve both stress tolerance and symbiotic performance of a chickpea microsymbiont, the Mesorhizobium mediterraneum UPM-Ca36T strain was genetically transformed with pPHU231 containing an extra-copy of the clpB gene. To investigate if the clpB-transformed strain displays an improved stress tolerance, bacterial growth was evaluated under heat and acid stress conditions. In addition, the effect of the extra-copies of the clpB gene in the symbiotic performance was evaluated using plant growth assays (hydroponic and pot trials. The clpB-transformed strain is more tolerant to heat shock than the strain transformed with pPHU231, supporting the involvement of ClpB in rhizobia heat shock tolerance. Both plant growth assays showed that ClpB has an important role in chickpea-rhizobia symbiosis. The nodulation kinetics analysis showed a higher rate of nodule appearance with the clpB-transformed strain. This strain also induced a greater number of nodules and, more notably, its symbiotic effectiveness increased ~60% at pH5 and 83% at pH7, compared to the wild-type strain. Furthermore, a higher frequency of root hair curling was also observed in plants inoculated with the clpB-transformed strain, compared to the wild-type strain. The superior root hair curling induction, nodulation ability and symbiotic effectiveness of the clpB-transformed strain may be explained by an increased expression of symbiosis genes. Indeed, higher transcript levels of the nodulation genes nodA and nodC (~3 folds were detected in the clpB-transformed strain. The improvement of rhizobia by addition of extra-copies of the clpB gene may be a promising strategy to obtain strains with enhanced stress tolerance and symbiotic effectiveness, thus contributing to their success as crop inoculants

    Desi-type chickpeas, which have long been used as a natural treatment for diabetes, have been reported to lower visceral adiposity, dyslipidemia and insulin resistance induced by a chronic high-fat diet in rats. In this study, in order to examine the effects of chickpeas of this type in an in vitro system, we used the 3T3-L1 mouse cell line, a subclone of Swiss 3T3 cells, which can differentiate into cells with an adipocyte-like phenotype, and we used ethanol extracts of chickpeas (ECP) instead of chickpeas. Treatment of the 3T3-L1 cells with ECP led to a decrease in the lipid content in the cells. The desaturation index, defined as monounsaturated fatty acids (MUFAs)/saturated fatty acids (SFAs), was also decreased by ECP due to an increase in the cellular content of SFAs and a decrease in the content of MUFAs. The decrease in this index may reflect a decreased reaction from SFA to MUFA, which is essential for fat storage. To confirm this hypothesis, we conducted a western blot analysis, which revealed a reduction in the amount of stearoyl-CoA desaturase 1 (SCD1), a key enzyme catalyzing the reaction from SFA to MUFA. We observed simultaneous inactivations of enzymes participating in lipogenesis, i.e., liver kinase B1 (LKB1), acetyl-CoA carboxylase (ACC) and AMPK, by phosphorylation, which may lead to the suppression of reactions from acetyl-CoA to SFA via malonyl-CoA in lipogenesis. We also investigated whether lipolysis is affected by ECP. The amount of carnitine palmitoyltransferase 1 (CPT1), an enzyme important for the oxidation of fatty acids, was increased by ECP treatment. ECP also led to an increase in uncoupling protein 2 (UCP2), reported as a key protein for the oxidation of fatty acids. All of these results obtained regarding lipogenesis and fatty acid metabolism in our in vitro system are consistent with the results previously shown in rats. We also examined the effects on SCD1 and lipid contents of ethanol extracts of Kabuli-type chickpeas, which are

    The ITS region sequence of a phosphate-solubilizing fungus isolated from the rhizosphere of tea growing in Kangra valley of Himachal Pradesh showed 96% identity with Discosia sp. strain HKUCC 6626 ITS 1, 5.8S rRNA gene and ITS 2 complete sequence, and 28S rRNA gene partial sequence. The fungus exhibited the multiple plant growth promoting attributes of solubilization of inorganic phosphate substrates, production of phytase and siderophores, and biosynthesis of indole acetic acid (IAA)-like auxins. The fungal inoculum significantly increased the root length, shoot length and dry matter in the test plants of maize, pea and chickpea over the uninoculated control under the controlled environment. The plant growth promoting attributes have not been previously studied for the fungus. The fungal strain with its multiple plant growth promoting activities appears attractive towards the development of microbial inoculants. PMID:23100761

    Full Text Available Wilt caused by Fusarium oxysporum f. sp. ciceris is a devastating disease of chickpea in India. One hundred and 26 RecombinantInbred Lines (RILs derived from a cross ICCV-2 x JG 62 along with six checks were evaluated for wilt resistance underunprotected natural infestation to identify the genetic sources for resistance. The genotypes were classified as highly resistant,moderately resistant, intermediate, susceptible and highly susceptible based on per cent plants wilted. Some of genotypesshowed high resistance to fusarium wilt. The per cent plants wilted in different lines ranged from O to 100 per cent. A total of45, 31, 25, 11 and 20 genotypes fell into highly resistant, moderately resistant, intermediate, susceptible and highly susceptibleclasses respectively. Less proportion of highly resistant genotypes were observed and it may be due to the fact that the wiltresistance was governed by recessive alleles. The resistant genotypes may be exploited for the development of resistant cultivarsagainst wilt.

    The present work describes radiation—induced effects on seed composition vis—à—vis total seed proteins, antioxidant levels and protein profiling employing two dimensional gel electrophoresis (2D—GE) in kabuli and desi chickpea varities. Seeds were exposed to the radiation doses of 1,2,3,4 and 5 kGy. The total protein concentrations decreased and antioxidant levels were increased with increasing dose compared to control seed samples. Radiation induced effects were dose dependent to these seed parameters while it showed tolerance to 1 kGy dose. Increase in the dose was complimented with increase in antioxidant levels, like 5 kGy enhanced % scavenging activities in all the seed extracts. Precisely, the investigations reflected that the dose range from 2 to 5 kGy was effective for total seed storage proteins, as depicted quantitatively and qualitative 2D—GE means enhance antioxidant activities in vitro.

  20. Nitrogen and water contribution of lentil, chickpea, wheat and fallow to the subsequent wheat crop in Jordan

    International Nuclear Information System (INIS)

    Beneficial effects of fallow have been attributed to soil water conservation and to increase of available nitrogen by mineralization. Benefits of fallow in the Middle Eastern Countries, regarding water conservation, is very low and almost all the water conserved in the root zone is lost through evaporation during summer. Studying nitrogen and water contribution of lentil, chickpea, wheat, and fallow to the subsequent wheat crop has not been previously measured in Jordan using 15N-labelled fertilizer and soil moisture neutron gauges. It was shown under 6 experimental treatments and 2 cropping seasons that (i) there were no significant differences between the treatments with respect total evapotranspiration; (ii) soil water depletion from the whole solid profile was highest for wheat fertilized with 50 kg N ha-1 (WWF2), whereas the lowest soil depletion was for chickpea fertilized with 20 kg N ha-1 (CWF1); (iii) the results show that the different treatments had no significant effect on %Ndff. This insignificant effect shows that the residual effect of the legumes is not effective, and the subsequent wheat did not benefit from it. This could be attributed to the following reasons: a) drought condition usually prevails in the region during flowering stage of lentil when most of the biological nitrogen fixation (BNF) takes place. Due to these adverse conditions it is anticipated that little BNF would take place; b) since the surface soil layers are most effected by drought conditions and since the nodules are concentrated on the upper part of the root zone it is expected that BNF would be minimal. To overcome this problem it is advised to examine new lentil varieties which can flower during early winter seasons. (author). 3 figs, 4 tabs

    Full Text Available Dough fermentation is one of the oldest process in food technologies. It has been recently intensively studied for its impact on the sensory, structural, nutritional and shelf life properties of leavened baked products. The goals of this work were to investigate chickpea steep liquor (CSL as a dough-leavening agent and to study the effect of CSL on the dough rheology and sensory properties of leavened bread. CSL was prepared by submerging chickpea seeds in boiled distilled water (1:2, w/v for 24 h at 37оC, and then obtained liquor was filtered and freeze-dried to obtain CSL. The addition of CSL to wheat flour (WF brought changes in the dough mixing behavior as measured by the farinograph. An increase in the farinograph water absorption of WF dough was observed when 4.5% CSL and 1.5% yeast was added, while arrival time was not affected. Addition of CSL to the dough at a content of 4.5, 9.0 and 13.5 g CSL/300 g WF caused an increase in dough stability. The CSL addition also increased mechanical tolerance index, dough weakening and mixing time. Dough development time for all blends was higher than the control (1.2-1.5 min, while between the CSL samples no significant difference was observed. The loaf weight slightly increased from 146.2 g for control to 152.2 g for CSL fermented bread, whereas the loaf volume and specific volume of CSL-fermented bread were lower than the control. The combination of yeast and CSL increased the acceptability of bread with the increasing level of both leavening agents’. The results show that CSL could be used as an alternative to yeast for syngas fermentation. On the other hand, CLS is rich in nutrients and lower in cost compared to yeast.

It was concluded that the A2 is a promising method which makes the maximum and positive effect to the first development of the chickpea agronomy under the semi-arid conditions.

  3. Induced mutations in chickpea (Cicer arietinum L.) I. comparative mutagenic effectiveness and efficiency of physical & chemical mutagens

    International Nuclear Information System (INIS)

    Mutagenic effectiveness usually means the rate of mutation as related to dose. Mutagenic efficiency refers to the mutation rate in relation to damage. Studies on comparative mutagenic effectiveness and efficiency of two physical (gamma rays and fast neutrons) and two chemical mutagens (NMU and EMS) on two desi (G 130 & H 214), one kabuli (C 104) and one green seeded (L 345) chickpea (Cicer arietinum L.) have been reported. The treatments included three doses each of gamma rays (400, 500 and 600 Gy) and fast neutrons (5, 10 and 15 Gy) and two concentrations with two different durations of two chemical mutagens, NMU 0.01% 20h and 0.02% 8h) and EMS (0.1% 20h and 0.2% 8h). Results indicated that chemical mutagens, particularly NMU are not only more effective but also efficient than physical mutagens in inducing mutations in chickpea. Mutagenic effectiveness and efficiency showed differential behaviour depending upon mutagen and varietal type. Chemical mutagens were more efficient than physical in inducing cholorophyll as well as viable and total number of mutations. Among the mutagens NMU was the most potent, while in the physical, gamma rays were more effective. Out of four mutagens, NMU was the most effective and efficient in inducing a high frequency and wide spectrum of chlorophyll mutations in the M2 followed by fast neutrons. While gamma rays showed least effectiveness, EMS was least efficient mutagens. Major differences in the mutagenic response of the four cultivars were observed. The varieties of desi type were more resistant towards mutagenic treatment than kabuli and green seeded type

    Due to the slowness growth and weakness of the first developments of chickpea (Cicer arietinum L.), it could not combated with weeds and easily caught up by Ascochyta blight (Ascochyta rabiei (Pass) Labr.) disease. Additionally, due to biotic and abiotic stress factors, esp. at the late sowing, important seed yield losses could be happened. To be able to avoid from them is only possible to accelerate of its first development as possible as. So, one of the best solutions to is to use chemical compounds such as Humic Acid (HA) known soil regulator under the semi-arid conditions. With this aim this research was performed in a Randomized Complete Block Design (RCBD) with four replications under semi-arid field conditions during (2008/2009) and (2009/2010) in Turkiye. Two cultivars (V1 = Gokce and V2 = Ispanyol) and four seed imbibition methods (A0 = 0, A1 = Tap Water, A2 = 1/2 Tap Water + 1/2 Humic acid (HA), A3 = Full HA, as w/w) and seven yield components Plant Height (PH), Number of Branches per Plant (NBP), Number of Pods per Plant (NPP), First Pod Height (NFP), Number of Seeds per Pod (NSP), Seed Weight per Plant (SWP) and 100-Seed weight (HSW) were investigated. The PH and FPH were affected the A0, the NBP, NPP and NSP were affected the A2 and the SWP and HSW were given the varied but not clear responses according to varieties for all the parameters in A1. The A0 and A1 were encouraged the germination and top soil of the plant but, the A2 to A3 were encouraged root system's development. It was concluded that the A2 is a promising method which makes the maximum and positive effect to the first development of the chickpea agronomy under the semi-arid conditions. PMID:22816177

    Full Text Available BACKGROUND: Biotrophic interaction between host and pathogen induces generation of reactive oxygen species that leads to programmed cell death of the host tissue specifically encompassing the site of infection conferring resistance to the host. However, in the present study, biotrophic relationship between Fusarium oxysporum and chickpea provided some novel insights into the classical concepts of defense signaling and disease perception where ROS (reactive oxygen species generation followed by hypersensitive responses determined the magnitude of susceptibility or resistant potentiality of the host. METHODOLOGY/PRINCIPAL FINDINGS: Microscopic observations detected wound mediated in planta pathogenic establishment and its gradual progression within the host vascular tissue. cDNA-AFLP showed differential expression of many defense responsive elements. Real time expression profiling also validated the early recognition of the wound inducing pathogen by the host. The interplay between fungus and host activated changes in primary metabolism, which generated defense signals in the form of sugar molecules for combating pathogenic encounter. CONCLUSIONS/SIGNIFICANCE: The present study showed the limitations of hypersensitive response mediated resistance, especially when foreign encounters involved the food production as well as the translocation machinery of the host. It was also predicted from the obtained results that hypersensitivity and active species generation failed to impart host defense in compatible interaction between chickpea and Fusarium. On the contrary, the defense related gene(s played a critical role in conferring natural resistance to the resistant host. Thus, this study suggests that natural selection is the decisive factor for selecting and segregating out the suitable type of defense mechanism to be undertaken by the host without disturbing its normal metabolism, which could deviate from the known classical defense mechanisms.

    Full Text Available Calcium ion (Ca2+ is a ubiquitous second messenger that transmits various internal and external signals including stresses and, therefore, is important for plants' response process. Calcineurin B-like proteins (CBLs are one of the plant calcium sensors, which sense and convey the changes in cytosolic Ca2+-concentration for response process. A search in four leguminous plant (soybean, Medicago truncatula, common bean and chickpea genomes identified 9 to 15 genes in each species that encode CBL proteins. Sequence analyses of CBL peptides and coding sequences (CDS suggested that there are nine original CBL genes in these legumes and some of them were multiplied during whole genome or local gene duplication. Coding sequences of chickpea CBL genes (CaCBL were cloned from their cDNAs and sequenced, and their annotations in the genome assemblies were corrected accordingly. Analyses of protein sequences and gene structures of CBL family in plant kingdom indicated its diverse origin but showed a remarkable conservation in overall protein structure with appearance of complex gene structure in the course of evolution. Expression of CaCBL genes in different tissues and in response to different stress and hormone treatment were studied. Most of the CaCBL genes exhibited high expression in flowers. Expression profile of CaCBL genes in response to different abiotic stresses and hormones related to development and stresses (ABA, auxin, cytokinin, SA and JA at different time intervals suggests their diverse roles in development and plant defence in addition to abiotic stress tolerance. These data not only contribute to a better understanding of the complex regulation of chickpea CBL gene family, but also provide valuable information for further research in chickpea functional genomics.

  8. Integration of Gamma Irradiation and Some Botanical oils To Protect Cowpea And Chickpea Seeds From Infestation With The Bruchid Beetle Callosobruchus Maculatus

    International Nuclear Information System (INIS)

    The lethal effect of gamma radiation doses of 0.75 or 1.0 kGy on the adults Callosobruchus maculates reared on cowpeas and chickpeas were slow during the first and third days post-treatments. By increasing the dose to 1.5 kGy, the values of the percent mortality of adults in both seeds 24 h posttreatment were 53 and 40%, respectively. On the other hand, the dose 2 kGy caused sooner mortality for adults post-treatment for cowpeas. Different concentrations from eight plant oils; lemon grass, pinus sylvestris, parsley, fennel, geranium, peppermint, petitgrain and sweet basil, were used for protection of cowpea and chickpea seeds from infestation by Callosobruchus maculates. The results showed that sweet basil and geranium caused 89 and 79 % larval mortality, respectively, in case of cowpeas at concentration 0.5 % with exposure period of 48 hour while 71.0 and 63.33% adult mortality was occurred at the same concentration of both oils in chickpeas. The latent effects of tested plant oils on adult stage when beetles of C. maculatus were fed on seeds treated with the lowest two concentrations (0.0312, 0.0625%) of tested oils, the number of eggs laid per female was decreased in female exposed to all tested oils especially in case of cowpea treated with sweet basil and lemongrass. Most of the tested oils caused high reduction in larval penetration in both types of seeds. The adult weight was non significantly reduced at all treatments. The use of different plant oils leads to reduction in the progeny comparing to the control and sweet basil or geranium was found to be highly effective in decreasing the percentage of emergence (30 and 40% , respectively). No harmful effect was observed on germination of plant oils treated cowpea and chickpea seeds with concentration 2%.

    Soil moisture stress during pod filling is a major constraint in production of chickpea (Cicer arietinum L.), a fundamentally dry land crop. We investigated effect of pre-sowing seed priming with static magnetic field (SMF) on alleviation of stress through improvement in radiation and water use efficiencies. Experiments were conducted under greenhouse and open field conditions with desi and kabuli genotypes. Seeds exposed to SMF (strength: 100 mT, exposure: 1 h) led to increase in root volume and surface area by 70% and 65%, respectively. This enabled the crop to utilize 60% higher moisture during the active growth period (78-118 days after sowing), when soil moisture became limiting. Both genotypes from treated seeds had better water utilization, biomass, and radiation use efficiencies (17%, 40%, and 26% over control). Seed pre-treatment with SMF could, therefore, be a viable option for chickpea to alleviate soil moisture stress in arid and semi-arid regions, helping in augmenting its production. It could be a viable option to improve growth and yield of chickpea under deficit soil moisture condition, as the selection and breeding program takes a decade before a tolerant variety is released.

    The present study reports in vivo antifungal and antiaflatoxigenic efficacy of Mentha spicata essential oil (EO) against toxigenic Aspergillus flavus strain LHP(C)-D6 in chickpea food system up to 12 months of storage. In addition, the mode of antifungal action of EO was also determined to understand the mechanism of fungal growth inhibition. The in vivo study with different concentrations of M. spicata EO showed dose-dependent decrease in fungal colony count as well as aflatoxin B1 concentration. The EO caused >50% protection in inoculated sets and >70% protection in uninoculated sets of chickpea food system against A. flavus at 1.0 μL mL(-1) air concentration. However, at the same concentration, EO caused 100% inhibition to aflatoxin B1 production in both sets when analyzed through high-performance liquid chromatography (HPLC). The antifungal target of EO in fumigated cells of A. flavus was found to be the plasma membrane when analyzed through electron microscopic observations and ions leakage test. The EO fumigated chickpea seeds showed 100% seed germination and seedling growth after 12 months of storage. Based on these observations, M. spicata EO can be recommended as plant-based preservative for safe protection of food commodities during storage conditions against fungal and most importantly mycotoxin contaminations.

    Full Text Available Eight kabuli chickpea genotypes (Cicer arietinum L. Beja1, Amdoun1, Nayer, Kasseb, Bochra, FLP96-114C, FLP88-42C and Chetoui were germinated, in vitro culture, on Whatman n° 2 filter paper media at four osmotic water pressures: -0,33; -4, -6 and -8 bars as induced by polyethylene glycol (PEG 8000. Osmotic water stress negatively affected germination parameters and enhanced soluble sugars and proline accumulation. Broad genotypic variability of the chickpea cultivars was revealed with respect to osmotic water stress. At -0,33 bars, germination occurred at a high rate and exhibited elevated germinative energy. On the other hand, OWP -8 bars proved too high, as it completely inhibited chickpea germination. Soluble sugars and proline accumulation were proportional to osmotic water pressures. Hierarchical cluster analysis revealed that under high OWP (-6 bars, genotypes Beja1, Amdoun1, Nayer, FLIP96-114C and Chetoui were sensitive to the osmotic water stress; whereas, Kasseb, Bochra and FLIP88-42C were tolerant.

  13. Promoter of CaZF, a chickpea gene that positively regulates growth and stress tolerance, is activated by an AP2-family transcription factor CAP2.

    Directory of Open Access Journals (Sweden)

    Deepti Jain

    Full Text Available Plants respond to different forms of stresses by inducing transcription of a common and distinct set of genes by concerted actions of a cascade of transcription regulators. We previously reported that a gene, CaZF encoding a C2H2-zinc finger family protein from chickpea (Cicer arietinum imparted high salinity tolerance when expressed in tobacco plants. We report here that in addition to promoting tolerance against dehydration, salinity and high temperature, the CaZF overexpressing plants exhibited similar phenotype of growth and development like the plants overexpressing CAP2, encoding an AP2-family transcription factor from chickpea. To investigate any relationship between these two genes, we performed gene expression analysis in the overexpressing plants, promoter-reporter analysis and chromatin immunoprecipitation. A number of transcripts that exhibited enhanced accumulation upon expression of CAP2 or CaZF in tobacco plants were found common. Transient expression of CAP2 in chickpea leaves resulted in increased accumulation of CaZF transcript. Gel mobility shift and transient promoter-reporter assays suggested that CAP2 activates CaZF promoter by interacting with C-repeat elements (CRTs in CaZF promoter. Chromatin immunoprecipitation (ChIP assay demonstrated an in vivo interaction of CAP2 protein with CaZF promoter.

    Full Text Available The identification of informative in silico polymorphic genomic and genic microsatellite markers by comparing the genome and transcriptome sequences of crop genotypes is a rapid, cost-effective and non-laborious approach for large-scale marker validation and genotyping applications, including construction of high-density genetic maps. We designed 1494 markers, including 1016 genomic and 478 transcript-derived microsatellite markers showing in-silico fragment length polymorphism between two parental genotypes (Cicer arietinum ICC4958 and C. reticulatum PI489777 of an inter-specific reference mapping population. High amplification efficiency (87%, experimental validation success rate (81% and polymorphic potential (55% of these microsatellite markers suggest their effective use in various applications of chickpea genetics and breeding. Intra-specific polymorphic potential (48% detected by microsatellite markers in 22 desi and kabuli chickpea genotypes was lower than inter-specific polymorphic potential (59%. An advanced, high-density, integrated and inter-specific chickpea genetic map (ICC4958 x PI489777 having 1697 map positions spanning 1061.16 cM with an average inter-marker distance of 0.625 cM was constructed by assigning 634 novel informative transcript-derived and genomic microsatellite markers on eight linkage groups (LGs of our prior documented, 1063 marker-based genetic map. The constructed genome map identified 88, including four major (7-23 cM longest high-resolution genomic regions on LGs 3, 5 and 8, where the maximum number of novel genomic and genic microsatellite markers were specifically clustered within 1 cM genetic distance. It was for the first time in chickpea that in silico FLP analysis at genome-wide level was carried out and such a large number of microsatellite markers were identified, experimentally validated and further used in genetic mapping. To best of our knowledge, in the presently constructed genetic map, we mapped

    Chickpea (Cicer arietinum L.) is particularly sensitive to water stress at its reproductive phase and, under conditions of water stress, will abort flowers and pods, thus reducing yield potential. There are two types of chickpea: (i) Macrocarpa ("Kabuli"), which has large, rams head-shaped, light brown seeds; and (ii)Microcarpa ("Desi"), which has small, angular and dark-brown seeds. Relatively speaking, "Kabuli" has been reported to be more sensitive to water stress than "Desi". The underlying mechanisms associated with contrasting sensitivity to water stress at the metabolic level are not well understood. We hypothesized that one of the reasons for contrasting water stress sensitivity in the two types of chickpea may be a variation in oxidative injury. In the present study, plants of both types were water stressed at the reproductive stage for 14 d. As a result of the stress, the "Kabuli" type exhibited an 80% reduction in seed yield over control compared with a 64% reduction observed for the "Desi" type. The decrease in leaf water potential (Ψw) was faster in the "Kabuli" compared with the "Desi" type. At the end of the water stress period, Ψ was reduced to -2.9 and -3.1 MPa in the "Desi" and "Kabuli" types, respectively, without any significant difference between them. On the last day of stress, "Kabuli" experienced 20% more membrane injury than "Desi". The chlorophyll content and photosynthetic rate were significantly greater in "Desi"compared with "Kabuli". The malondialdehyde and H2O2 content were markedly higher at the end of the water stress in "Kabuli" compared with "Desi", indicating greater oxidative stress in the former. Levels of anti-oxidants, such as ascorbic acid and glutathione, were significantly higher in "Desi" than "Kabuli".Superoxide dismutase and catalase activity did not differ significantly between the two types of chickpea,whereas on the 10th day, the activities of ascorbate peroxidase, dehydroascorbate reductase, and glutathione

    Full Text Available Eleven fungal isolates were isolated from naturally infected chickpea roots collected from different locations in New Valley Governorate (Egypt. The isolated fungi were purified and identified as Rhizoctonia solani (5 isolates, Fusarium solani (4 isolates and Sclerotinia sclerotiorum (2 isolates. The isolated fungi proved their pathogenicity on cv. �Giza 3�. Response of chickpea cvs. �Giza 1�, �Giza 2�, �Giza 3�, �Giza 4�, �Giza 88�, �Giza 195�, �Giza 531� to infection by the tested fungi was significantly varied. �Giza 1� was the most resistant one followed by �Giza 531�, while the other tested cvs. were highly susceptible. Seven biocontrol agents, namely Bacillus subtilis, B. megaterium, B. cereus, Trichoderma viride, T. harzianum, Aspergillus sp., Penicillium sp. isolated from chickpea rhizosphere, were tested for their antagonistic action against the tested pathogens. B. subtilis isolate BSM1, B. megaterium isolate TVM5, T. viride isolate TVM2 and T. harzianum isolate THM4 were the most antagonistic ones to the tested fungi in vitro, while the other isolates were moderate or weak antagonists. The most antagonistic isolates as well as the commercial biocide Rhizo-N were applied as seed treatment for controlling damping-off, root and/or stem rot diseases caused by the tested fungi under greenhouse conditions. The obtained data showed that all tested antagonistic isolates were able to cause significant reduction of damping-off, root and/or stem rot diseases in chickpea plants. T. viride (isolate TVM2 and B. megaterium (isolate BMM5 proved to be the most effective isolates for controlling the diseases. Under field condition, the obtained data indicated that all the tested antagonistic isolates significantly reduced damping-off, root and/or stem rot. T. viride (isolate TVM2 and B. megaterium (isolate BMM5 recorded the highest reduction of damping-off, root and/or stem rot in all sowing dates. Sowing of

    International Nuclear Information System (INIS)

    A field experiment was conducted to evaluate the effect of phosphorus (P) levels and Rhizobium inoculation on yield-components and grain-yield of (chickpea c.v. NIFA-88) under rain fed conditions at Arid Zone Research Institute, Dera Ismail Khan, during 2003- 04. The treatments consisted of P levels; 0, 30, 60 and 90 kg ha-I, with and without inoculum. A basal dose of 20 kg ha-l nitrogen was applied just before sowing, at the time of seedbed preparation. The experiment was laid out according to the randomized complete block design, with three replications. The results showed significant variation in number of pods per plant, 1000 seed weight and grain yield, with the application of P and Rhizobium inoculum. The maximum number of pods per plant (25.00) was recorded in the plots receiving 60 kg P/sub 2/ O/sub 5/ h a/sup -l/ plus inoculum, but was statistically at par with the pods produced by the treatment of 90 kg P/sub 2/ O/sub 5/ ha-l plus inoculum (24.67). Phosphorus levels plus inoculum gave 11.87 percent increased number of pods per plant over mere P levels. Similarly, the maximum 1000 seed weight of 197.0 g was recorded at the rate 90 and 60 kg P/sub 2/O/sub 5/ ha-1 plus inoculum and 90 kg P/sub 2/ O/sub 5/ ha-l alone. The highest grain-yield of 1,317 kg ha/sup -l/ was obtained from the treatments where P was applied at the rate 90 and 60 kg ha-I with inoculum. The grain yield was increased 8.54 percent when P levels were applied with inoculums, as compared to Palone, on average basis. Hence, it can be concluded from the study that (I) Rhizobium inoculum application alone can increase yield, and (II) 60 kg P/sub 2/ O/sub 5/ ha-l is the most economical dose to be used with Rhizobium inoculum for obtaining higher grain-yield of chickpea.

    Full Text Available The effect of some natural lignocellulosic substances on the production of ß-glucanase, chitinase, protease and xylanase from Trichoderma harzianum L1 has been studied under solid state fermentation conditions. Maximum activities of all these enzymes were observed in the fermentation medium containing the mixture of 1% rice bran, neem cake and 0.1% crab shell powder. The induction of plant defense response was investigated by inoculating the roots of chickpea cv JG62 with the biocontrol agent, T. harzianum L1. A root extract of chickpea inoculated with T. harzianum L1 showed increased activities of phenylalanine ammonia lyase and polyphenol oxidase, as well as induction of new trypsin and chymotrypsin inhibitors. The Fusarium oxysporum protease-2 was inhibited completely by root extract of chickpea inoculated with T. harzianum L1 and showed maximum resistance to rotting of roots caused by wilt disease

    International Nuclear Information System (INIS)

    Comparative mutagenic effectiveness and efficiency of gamma rays and Ethyl methane sulphonate (EMS) were studied in two desi (Pb2000 and C44), one kabuli (Pb1) and one desi x kabuli introgression line (CH40/91) of chickpea. The treatments included two doses each of gamma rays and EMS calculated on the basis of their LD30. The results revealed that EMS was almost seven times more effective and its efficiency was two times higher than that of gamma rays. Mutagenic effectiveness and efficiency were found to depend upon mutagen type and the genotype and both were higher at lower doses of EMS in three genotypes except in desi genotype C44. The overall trend of mutagenic effectiveness and efficiency in both gamma radiation and EMS was in the order i.e. CH40/91 greater than Pb2000 greater than Pb1 greater than C44. The introgression line desi x kabuli genotype was found to be most resistant towards mutagenic treatments than desi and kabuli types

    Plant growth promoting rhizobacteria (PGPR), are associated with roots, found in the rhizosphere and can directly or indirectly enhance the plant growth. In this study soil was collected from rhizosphere of chickpea fields of different areas of Rawalpindi division of Pakistan. PGPR were isolated, screened and characterized. Eight isolates of rhizobacteria (RHA, RPG, RFJ, RC, RTR, RT and RK) were isolated from Rawalpindi division and were characterized. The antagonistic activity of these PGPR isolates against root infecting fungi (Fusarium oxysporum and Verticillium spp.,) was done and production of indole acetic acid (IAA), siderophore and P-solubilization was evaluated. The isolates RHA, RPG, RFJ, RC, RRD and RT were found to be positive in producing siderophore, IAA and P-solubilization. Furthermore, most of the isolates showed antifungal activity against Fusarium oxysporum, and Verticillium spp. The rhizobacterial isolates RHA, RPG, RFJ, RC, RRD, RTR, RT and RK were used as bio-inoculants that might be beneficial for chickpea cultivation as the rhizobacterial isolates possessed the plant growth promoting characters i.e. siderophore, IAA production, phosphate solubilization. In in vitro tests, Pseudomonas sp. and Bacillus spp. inhibited the mycelial growth of the fungal root pathogens. The isolates (RHA and RPG) also significantly increased (60-70%) seed germination, shoot length, root length of the chickpea. The incidence of fungi was reduced by the colonization of RHA and RPG which enhanced the seedling vigor index and seed germination. The observations revealed that isolates RHA and RPG is quite effective to reduce the fungal root infection in greenhouse, and also increases seed yields significantly. These rhizobacterial isolates appear to be efficient yield increasing as well as effective biocontrol agent against fungal root pathogen. (author)

    To understand the genetic basis of tolerance to drought and heat stresses in chickpea, a comprehensive association mapping approach has been undertaken. Phenotypic data were generated on the reference set (300 accessions, including 211 mini-core collection accessions) for drought tolerance related root traits, heat tolerance, yield and yield component traits from 1-7 seasons and 1-3 locations in India (Patancheru, Kanpur, Bangalore) and three locations in Africa (Nairobi, Egerton in Kenya and Debre Zeit in Ethiopia). Diversity Array Technology (DArT) markers equally distributed across chickpea genome were used to determine population structure and three sub-populations were identified using admixture model in STRUCTURE. The pairwise linkage disequilibrium (LD) estimated using the squared-allele frequency correlations (r2; when r2<0.20) was found to decay rapidly with the genetic distance of 5 cM. For establishing marker-trait associations (MTAs), both genome-wide and candidate gene-sequencing based association mapping approaches were conducted using 1,872 markers (1,072 DArTs, 651 single nucleotide polymorphisms [SNPs], 113 gene-based SNPs and 36 simple sequence repeats [SSRs]) and phenotyping data mentioned above employing mixed linear model (MLM) analysis with optimum compression with P3D method and kinship matrix. As a result, 312 significant MTAs were identified and a maximum number of MTAs (70) was identified for 100-seed weight. A total of 18 SNPs from 5 genes (ERECTA, 11 SNPs; ASR, 4 SNPs; DREB, 1 SNP; CAP2 promoter, 1 SNP and AMDH, 1SNP) were significantly associated with different traits. This study provides significant MTAs for drought and heat tolerance in chickpea that can be used, after validation, in molecular breeding for developing superior varieties with enhanced drought and heat tolerance.

    Chickpea is an important food legume crop of Turkey and is largely grown for human consumption on low moisture or salt-affected soils.The objective of the study was to find the effects of NaCl stress at electrical conductivities of 4.5,8.6,12.7 and 16.3 dS/m and seed sizes (7,8 and 9 mm) on germination and early seedling growth of three popular chickpea cultivars (AKN-97,Gokce and Uzunlu-99).Mean frequency of germination,germination time,germination index,root length,shoot length and seedling fresh weight showed seed size-dependent responses of cultivars to salt stress.In general,small seeds germinated and grew more rapidly compared to medium and large seeds of the same cultivars against all levels of salt stress,with the best results in cultivar Uzunlu-99.No effect of NaCl treatments was observed on frequency of germination; however,a drastic decrease in early seedling growth was recorded at increased NaCl concentrations.Regression analysis results showed a significantly positive rela-tionship (P<0.01) between seed size and mean germination time,whereas a significantly negative relationship was recorded between seed size and germination index,root length,shoot length.Moreover,linear regression values apparently confirmed that increased seed size in each cultivar affected decreased germination index,root and shoot lengths with enhanced mean germination time.Thus,it was concluded that the use of small seeds could considerably reduce the production costs of chickpea in salt-affected soils.

    To increase the DH of chickpea protein, and provide the basis for industrialization of the enzymatic production of chickpea producing oligopeptides, the optimal condition for alcalase hydrolysis of chickpea protein was studied. The degree of hydrolysis (DH) was determined according to the pH-state method. Through a single-factor test and an orthogonal designed experiment, the alcalase hydrolysis of chickpea protein was systematically studied. Then, the three proteases of alcalase,papain and bromelain commonly hydrolyzing chickpea protein was carried out to increase the DH of chickpea protein. The results showed that the obtained optimum hydrolysis with alcalase condition was pH 8.5, temperature (T) 55℃, concentration of substrate [S] 2%, and ratio of enzyme and substate ([E]/[S]) 2%. Under this condition, the degree of hydrolysis (DH) was 27.86%. Under each optimum conditions of the three proteases respectively (The obtained optimum hydrolysis condition of alcalase was pH 8.5, temperature (T) 55℃, concentration of substrate [S] 2%, and ratio of enzyme and substate ([E]/[S]) 2%.

  9. Evaluation of some chemical and technological properties of induced erect chickpea mutant lines developed under drought stressed conditions

    International Nuclear Information System (INIS)

    Seeds of the chickpea variety Flip 99-47 C were treated with gamma rays at doses of 0, 50 and 75 Gy and sown in the winter season of 2004/2005 to raise M1 generation under ordinary (normal) irrigation conditions. Bulked seeds from each treatment were planted in the subsequent growing seasons of 2005/2006 and 2006/2007 to advance M2 and M3 generations, respectively under either ordinary (normal) irrigation or drought stress condition. In the third generation, three erect mutant lines were derived from 75 Gy mutagenic treatment under drought stress compared to semi spreading growth habit of the initiated variety Flip 99-47 C. In the winter season of 2007/2008, M4 bulked seeds from the three erect lines as well as unirradiated seeds of the original variety grown under either ordinary (normal) irrigation (2152.5 m3/fad.) or drought (1159.2 m3/fad.) conditions were analyzed for the chemical composition and nutritional values. Obtained results indicated that there were slight decreases in protein and fat contents accompanied with marginal increases in both ash and carbohydrates in seed samples of the erect mutant developed under drought stress as compared to unirradiated seeds of the original variety grown under ordinary (normal) irrigation treatment. An opposite trend was noticed between seed samples derived from the erect lines compared to seeds of the parent variety developed under drought condition. Negligible changes in levels of the minerals (iron, magnesium, calcium and phosphorus) were detected between seeds of the erect lines and the original variety that grown under either ordinary (normal) irrigation or drought conditions. Cooking time (min) and hydration coefficient values did not much differ between the three tested seed samples. Marginal differences in essential and non-essential amino acids were detected between seeds of the erect mutants and those of the initial variety grown under ordinary (normal) irrigation or drought stressed conditions

  10. From chickpeas to oil. The keys to fifteen years of hispanic-mexican economic relations (1977-1992

    Santiago Forcada

    1993-07-01

    Full Text Available This article intends to analyse the evolution of economic relations between Spain and Mexico from the reestablishment of diplomatic relations taking into account both the keys to this evolution and its changes. The authors highlight three distinct periods : a boom between 1977 and 1981 ; a relapse between 1982 and 1986 and a recovery between 1987 and 1992. This division into periods takes note of an initial spectacular increase in which bilateral exchanges were multiplied up to 33 times. A five year period in which oil replaced chickpeas as the main product bought in Mexico (up to four-fifths of the total volume and in which Spanish exports multiplied themselves ten times over. Already from this first phase, the commercial balance was clearly in favour of Mexico, a fact more striking during the second period, during which Spanish imports fell up to 50% but whileher exports were reduced by two-thirds. The key was the fall in the price of oil. The continuity of Spanish oil buying in Mexico however precipitated the recovery of the third period which coincided with the signing of the General Friendship and Cooperation Agreement between both countries. In 1992 Spain regained second place as a customer of Mexico behind the United States while the joint political policies coincide in pointing out that these are two reciprocal pathways to both the EC and US markets. The authors however, sustain that the global evolution of economic blocks does not favour this vision bearing in mind that the composition of and leadership in trade between such blocks will be governed, basically, by the strategies deployed by transnational companies.

    Full Text Available Soil application of organics has been explored as an alternative means of organic management of plant-parasitic nematodes. Efficiency of different oil-seed cakes of neem (Azadirachta indica, castor (Ricinus communis, groundnut (Arachis hypogaea, linseed (Linum usitatissimum, sunflower (Helianthus annuus and soybean (Glycine max were evaluated in field conditions with association of Pseudomonas fluorescens in relation to growth parameters of chickpea and population of plant-parasitic nematodes. Their efficacious nature was highly effective in reducing the population of these dominant soil nematodes. Significant improvement was observed in plant-growth parameters such as plant weight, percent pollen fertility, pod numbers, root-nodulation and chlorophyll content of chickpea, seemed to be due to reduction in disease incidence and might be due to growth promoting substances secreted by P. fluorescens. The multiplication rate of nematodes was less in the presence of P. fluorescens as compared to its absence. Most effective combination of P. fluorescens was observed with neem cake.

  12. Purification, crystallization and X-ray characterization of a Kunitz-type trypsin inhibitor protein from the seeds of chickpea (Cicer arietinum)

    International Nuclear Information System (INIS)

    The purification, characterization and crystallization of a trypsin inhibitor protein isolated from chickpea seeds are reported. A Kunitz-type trypsin inhibitor protein (CPTI) purified from chickpea seeds was estimated to have a molecular mass of 18 kDa on SDS–PAGE. The IC50 value of CPTI was determined to be 2.5 µg against trypsin. The inhibitory activity of CPTI is 114 TIU (trypsin inhibitory units) per milligram of protein, which is high compared with those of other known Kunitz-type trypsin inhibitors from legumes. CPTI crystallized in three different orthorhombic crystal forms: P21212 form A, P21212 form B and P212121. The crystals of P21212 form A, with unit-cell parameters a = 37.2, b = 41.2, c = 104.6 Å, diffracted to 2.0 Å resolution at the home source and to 1.4 Å on beamline BM14 at the ESRF. Data were also collected from crystals grown in the presence of iodine. The Matthews coefficient for these crystals was calculated to be 2.37 Å3 Da−1, corresponding to a solvent content of 42%. The other two crystal forms (P21212 form B and P212121) diffracted comparatively poorly

  13. Development and application of sequence-tagged microsatellite site (STMS) markers in chickpea (Cicer arietinum), banana (Musa spp.) and their major pathogens, Ascochyta rabiei and Mycosphaerella fijiensis

    International Nuclear Information System (INIS)

    DNA markers of various kinds have found widespread application in many facets of plant breeding and plant pathogen control. Yet another marker type, sequence-tagged microsatellite (STMS) markers, provides the markers of choice for nearly every crop because of their co-dominant nature, reliability, ease of application and high polymorphic information content. We report here on the development of a whole set of STMS markers and the respective, selected primer sequences for two important crops, chickpea (Cicer arietinum L.) and banana (Musa acuminata), and for their most devastating fungal pathogens, Ascochyta rabiei and Mycosphaerella fijiensis, respectively. These markers were generated either by direct screening of size-selected genomic libraries with microsatellite-complementary oligonucleotides, or by enrichment of DNA fragments containing microsatellite sequences. A total of 69 markers for chickpea, 15 markers for M. acuminata, 19 markers for A rabiei and 11 markers for M. fijiensis, selected on the basis of their high information content and ease of use are presented here. These can be applied for mapping of the respective genomes, for various population studies, and cultivar and isolate identification. We further demonstrate that several of these markers can potentially be applied across species boundaries and thus could increase the marker repertoire also for other species of the genus Cicer, Musa and for Ascochyta-type pathogens of bean, and potentially also of lentil and pea.

  14. Dry matter yield, carbon isotope discrimination and nitrogen uptake in silicon and/ or potassium fed chickpea and barley plants grown under water and non-water stress conditions

    International Nuclear Information System (INIS)

    A pot experiment was conducted to study the effects of silicon (Si) and/or potassium (K) on dry matter yield, nitrogen uptake and carbon isotope discrimination Δ 13C in water stressed (FC1) and well watered (FC2) chickpea plants using 15N and 13C isotopes. Three fertilizer rates of Si (Si50, Si100 and Si200) and one fertilizer rate of K were used. The results showed that: In chickpeas, it was found, for most of the growth parameters, that Si either alone or in combination with K was more effective to alleviate water stress than K alone. Increasing soil water level from FC1 to FC2 often had a positive impact on values of most studied parameters. The Si100K+ (FC1) and Si50K+ (FC2) treatments gave high enough amounts of N2-fixation, higher dry matter production and greater nitrogen yield. The percent increments of total N2-fixed in the above mentioned treatments were 51 and 47% over their controls, respectively. On the other hand, increasing leaves dry matter in response to the solely added Si (Si50K- and Si100K-) is associated with lower Δ13C under both watering regimes. This may indicate that Si fertilization had a beneficial effect on water use efficiency (WUE). Hence, Δ13C could be an adequate indicator of WUE in response to the exogenous supply of silicon to chickpea plants. Our results highlight that Si is not only involved in amelioration of growth and in maintaining of water status but it can be considered as an important element for the symbiotic performance of chickpea plants. It can be concluded that synergistic effect of silicon and potassium fertilization with adequate irrigation improves growth and nitrogen fixation in chickpea plants.In barley plants, solely added K or in combination with adequate rate of Si (Si100) were more effective in alleviating water stress and producing higher yield in barley plants than solely added Si. However, the latter nutrient was found to be more effective than the former in producing higher spike's N yield. Solely

    Full Text Available [english] Background: A number of studies have shown that non-critical medical devices can be contaminated with pathogens, including those resistant to antibiotics and thus become a potential vector for transmission. Electrocardiography (ECG lead wire are non-critical medical device which are always attached on patient skin during their stay in intensive care unit (ICU. In view of the patient’s critical conditions and exposure to invasive procedures, identification and prevention of possible risks are important to prevent infection in ICUs. Objective: The objective of this study was to determine the presence of bacterial and fungal contamination on cleaned and disinfected reusable ECG lead wires in intensive care units in a hospital.Methods: A total of 408 cleaned ECG lead wires from 93 bed-side ECG devices and 43 ECG lead wires from 5 portable ECG devices from 4 intensive care units (ICUs and 1 post-anaesthesia care unit (PACU were sampled. ECG lead wires were stirred in 0.89% NaCl with added neutralizer for 30 seconds. Samples of the solutions were cultured directly on blood agar. The remaining solution was cultured on blood agar after sterile filtration. The number of colony forming units (CFUs was counted and the microorganisms were identified.Results: More than half of examined ECG lead wires (n=232; 51.4% were contaminated with >30 CFUs/mL sample of bacteria or with risk pathogens. Gram-positive bacteria were the most frequently isolated organisms; particularly, (96% and aerobic spore forming bacteria (71.2%. Compared to ICUs, PACU had significantly lower proportion of contaminated ECG lead wires (p<0.05. The proportion of contaminated ECG lead wires, as well as mean number of cfus per ECG lead wire, was also significantly lower among multi-wire ECG leads compared to single-wire ECG leads. Conclusions: Manually cleaned ECG lead wires may serve as a vector for transmission of nosocomial pathogens. The current reprocessing technique for ECG lead wires needs to be improved.

  20. Spectrum of morphological mutations induced by separate and simultaneous application of gamma rays with GA3 in chickpea (Cicer arietinum L.)

    International Nuclear Information System (INIS)

    Three chickpea genotypes viz., Noor 91 (white), Punjab 91 (brown) and C 141 (black) were treated with 40, 50 and 60 Kr doses of gamma irradiation separately and post mutagenically with gibberellic acid (GA3) to create genetic variability. M2 progenies of these treatments were raised from M1 seeds in plant to family manner. The results indicated that induced mutability is governed by the genetic architecture of the material used. Various morphological mutations induced affecting plant height, growth habit, branching and stem structure, stem and foliage colour, leaf type, flowering and maturity, pod and seed type. There were differences between the genotypes and between the two types of treatments. Frequency of these mutants increased with gamma irradiation in Noor 91 and C 141 while, with GA3 it tended to increase in the three genotypes

    The physiological and molecular responses of five strains of Streptomyces sp. (CAI-17, CAI-68, CAI-78, KAI-26 and KAI-27), with their proven potential for charcoal rot disease control in sorghum and plant growth-promotion (PGP) in sorghum and rice, were studied to understand the mechanisms causing the beneficial effects. In this investigation, those five strains were evaluated for their PGP capabilities in chickpea in the 2012-13 and 2013-14 post-rainy seasons. All of the Streptomyces sp. strains exhibited enhanced nodule number, nodule weight, root weight and shoot weight at 30 days after sowing (DAS) and pod number, pod weight, leaf area, leaf weight and stem weight at 60 DAS in both seasons over the un-inoculated control. At crop maturity, the Streptomyces strains had enhanced stover yield, grain yield, total dry matter and seed number plant(-1) in both seasons over the un-inoculated control. In the rhizosphere, the Streptomyces sp. also significantly enhanced microbial biomass carbon, dehydrogenase activity, total nitrogen, available phosphorous and organic carbon in both seasons over the un-inoculated control. Of the five strains of Streptomyces sp., CAI-17, CAI-68 and CAI-78 were superior to KAI-26 and KAI-27 in terms of their effects on root and shoot development, nodule formation and crop productivity. Scanning electron microscopy (SEM) micrographs had revealed the success in colonization of the chickpea roots by all five strains. Quantitative real-time PCR (qRT-PCR) analysis of selected PGP genes of actinomycetes revealed the selective up-regulation of indole-3-acetic acid (IAA)-related and siderophore-related genes by CAI-68 and of β-1,3-glucanase genes by KAI-26.

    This study aimed at investigating the addition of legume (chickpea, lentil and bean) flours to wheat flour bread. Type I sourdough containing legumes or wheat-legume flours were prepared and propagated (back slopped) in laboratory, according to traditional protocols that are routinely used for making typical Italian breads. Based on kinetic of acidification and culture-dependent data, the wheat-legume sourdough was further characterized and selected for bread making. As determined by RAPD-PCR and partial sequencing of 16S rDNA gene analyses, lactic acid bacteria in wheat-legume sourdough included Lactobacillus plantarum, Lactobacillus sanfranciscensis, Leuconostoc mesenteroides, Lactobacillus fermentum, Weissella cibaria, Lactobacillus pentosus, Lactobacillus coryneformis, Lactobacillus rossiae, Lactobacillus brevis, Lactobacillus parabuchneri and Lactobacillus paraplantarum. Two breads containing 15% (w/w) of legume (chickpea, lentil and bean) flours were produced using selected wheat-legume sourdough (WLSB) and traditional wheat sourdough (WSB). Compared to wheat yeasted bread (WYB), the level of total free amino acids (FAA) was higher in WSB and WLSB. Phytase and antioxidant activities were the highest in WLSB. Compared to bread WYB, the addition of legume flours decreased the in vitro protein digestibility (IVPD) (WYB versus WSB). However, the dough fermentation with WSLB favored an increase of IVPD. According to the levels of carbohydrates, dietary fibers and resistant starch, WSB and WLSB showed lower values of hydrolysis index (HI) compared to WYB. As showed by texture and image analyses and sensory evaluation of breads, a good acceptability was found for WSB and, especially, WLSB breads. PMID:24794619

    Oil bleeding during storage oleaginous seeds based confectionery products is a major problem affecting acceptance by consumers. Halva is a popular sweet food prepared from a sesame paste and a sugar mixture. The objective of this work was to improve the oil retention in this product by incorporating commercial fibers and emulsifiers: soya lecithin and monoglycerides (MG1 or MG2) during manufacturing. Oil retention yield was optimized on small batches, by response surface methodology using a central composite design applied with two factors, emulsifier concentration (0.25-2.25 %) and fibers concentration (0-2 %) at three levels. A centrifugation test was optimized to assess oil retention in halva samples. The experimental response (oil retention) was fitted with quadratic equations for each emulsifier, using multiple regression analysis. The emulsion stability increased with increasing the emulsifier concentration, particularly to 2.25 %. The oil bleeding assessed at 45 °C was slow but yielded similar results to those estimated by centrifugation test. The latter seems an attractive rapid method to quantify oil retention in oleaginous seeds and crops based food matrices. At an industrial scale, the increase of MG1 concentration to 2.25 % in halva enhances the oil retention of the product but does not affect its color or textural characteristics. Microscopic observations allowed us to explain high oil retention in this product by a homogeneous dispersion of oil droplets in the aqueous phase. PMID:27570279

    Full Text Available Chickpea (Cicer arietinum L. is the third most important cool season food legume, cultivated in arid and semi-arid regions of the world. The goal of this study was to develop novel molecular markers such as microsatellite or simple sequence repeat (SSR markers from bacterial artificial chromosome (BAC-end sequences (BESs and diversity arrays technology (DArT markers, and to construct a high-density genetic map based on recombinant inbred line (RIL population ICC 4958 (C. arietinum×PI 489777 (C. reticulatum. A BAC-library comprising 55,680 clones was constructed and 46,270 BESs were generated. Mining of these BESs provided 6,845 SSRs, and primer pairs were designed for 1,344 SSRs. In parallel, DArT arrays with ca. 15,000 clones were developed, and 5,397 clones were found polymorphic among 94 genotypes tested. Screening of newly developed BES-SSR markers and DArT arrays on the parental genotypes of the RIL mapping population showed polymorphism with 253 BES-SSR markers and 675 DArT markers. Segregation data obtained for these polymorphic markers and 494 markers data compiled from published reports or collaborators were used for constructing the genetic map. As a result, a comprehensive genetic map comprising 1,291 markers on eight linkage groups (LGs spanning a total of 845.56 cM distance was developed (http://cmap.icrisat.ac.in/cmap/sm/cp/thudi/. The number of markers per linkage group ranged from 68 (LG 8 to 218 (LG 3 with an average inter-marker distance of 0.65 cM. While the developed resource of molecular markers will be useful for genetic diversity, genetic mapping and molecular breeding applications, the comprehensive genetic map with integrated BES-SSR markers will facilitate its anchoring to the physical map (under construction to accelerate map-based cloning of genes in chickpea and comparative genome evolution studies in legumes.

    Full Text Available The study was conducted to determine the effect of phosphate solubilizing bacteria (N2; Bacillus megaterium M-3, TV-6I; Cellulosimicrobium cellulans, TV-34A; Hafnia Alve, TV-69E; Acetobacter pasteurianus and TV-83F; Bacillus cereus and organic fertilizer (0, 10 and 20 ton / ha on the seed yield and nutrient content of chickpea under field conditions in 2010 and 2011 growing seasons. Phosphate solubilizing bacteria used in this study were determined by the separate investigation conducted in chamber room by using ten phosphate solubilizing bacteria and organic fertilizer (control, %5,%10. The tiral were laid out with a factorial design in randomized complete block with three replications. In this study, plant height, primary branches, secondary branches and number of pods per plant, number of seeds per pod, grain yield and biological yield and nutrient content of stem and seed were determined. According to the results of the study bacteria applications increased significantly biological and seed yield. Bacteria applications without organic fertilizer increased nutrient contents of seed and steed except cupper content. In case of inoculation with organic fertilizer provided more increases in biological and seed yields. The highest seed yield were obtained from application of 20 ton/ha + N2 (Bacillus megaterium M-3 with 1020 kg/ha and 1793 kg/ha in 2010 and 2011 years, respectively. Bacteria without organic fertilizer application were more active in terms of phosphorus uptake in both years. 

  7. Contribution of applied and soil phosphorus and sulphur in chickpea (Cicer arietinum L.) as influenced by Fe and Rhizobium inoculation in a Typic haplustept

    International Nuclear Information System (INIS)

    In an experiment with a test crop of chickpea during rabi, 1999-2000 the influence of P, S and Fe on the uptake of P and S was assessed using isotopic tracers (32P and 35S). It was found that the dry matter production increased by the application of phosphorus at 60 kg P2O5 ha-1 in both with and without Rhizobium inoculation and the combined application of P and Fe produced higher dry matter of both shoot and roots with inoculation. An assessment of the radioassay of applied phosphate and sulphate showed lower values of per cent derived from fertilizer in respect of both P and S. However, the values of phosphorus derived from fertilizer (Pdff) were comparatively higher due to combined application of P, S and Fe and those for sulphur due to phosphorus and sulphur only. The contribution of phosphorus from soil was more due to combined application of phosphorus and sulphur against the inoculation treatment, whereas, the contribution of phosphorus from fertilizer was observed to be improved due to applied phosphorus and iron along with the inoculation. Contribution of soil source for sulphur uptake increased with the application of sulphur along with iron or phosphorus both with and without inoculation. (author)

    This work examined the role of exogenously applied calcium (Ca; 50 mM) and potassium (K; 10 mM) (alone and in combination) in alleviating the negative effects of cadmium (Cd; 200 μM) on growth, biochemical attributes, secondary metabolites and yield of chickpea (Cicer arietinum L.). Cd stress significantly decreased the length and weight (fresh and dry) of shoot and root and yield attributes in terms of number of pods and seed yield (vs. control). Exhibition of decreases in chlorophyll (Chl) a, Chl b, and total Chl was also observed with Cd-exposure when compared to control. However, Cd-exposure led to an increase in the content of carotenoids. In contrast, the exogenous application of Ca and K individually as well as in combination minimized the extent of Cd-impact on previous traits. C. arietinum seedlings subjected to Cd treatment exhibited increased contents of organic solute (proline, Pro) and total protein; whereas, Ca and K-supplementation further enhanced the Pro and total protein content. Additionally, compared to control, Cd-exposure also caused elevation in the contents of oxidative stress markers (hydrogen peroxidase, H2O2; malondialdehyde, MDA) and in the activity of antioxidant defense enzymes (superoxide dismutase, SOD; catalase, CAT; ascorbate peroxidase, APX; glutathione reductase, GR). Ca, K, and Ca + K supplementation caused further enhancements in the activity of these enzymes but significantly decreased contents of H2O2 and MDA, also that of Cd accumulation in shoot and root. The contents of total phenol, flavonoid and mineral elements (S, Mn, Mg, Ca and K) that were also suppressed in Cd stressed plants in both shoot and root were restored to appreciable levels with Ca- and K-supplementation. However, the combination of Ca + K supplementation was more effective in bringing the positive response as compared to individual effect of Ca and K on Cd-exposed C. arietinum. Overall, this investigation suggests that application of Ca and/or K can

    For black-hole binaries whose spins are (anti-) aligned with respect to the orbital angular momentum of the binary, we compute the frequency-domain phasing coefficients including the quadratic-in-spin terms up to the third post-Newtonian (3PN) order, the cubic-in-spin terms at the leading order, 3.5PN, and the spin-orbit effects up to the 4PN order. In addition, we obtain the 2PN spin contributions to the amplitude of the frequency-domain gravitational waveforms for nonprecessing binaries, using recently derived expressions for the time-domain polarization amplitudes of binaries with generic spins, complete at that accuracy level. These two results are updates to [K. G. Arun, A. Buonanno, G. Faye, and E. Ochsner, Phys. Rev. D 79, 104023 (2009).] for amplitude and [M. Wade, J. D. E. Creighton, E. Ochsner, and A. B. Nielsen, Phys. Rev. D 88, 083002 (2013).] for phasing. They should be useful for constructing banks of templates that accurately model nonprecessing inspiraling binaries, for parameter estimation studies, and for constructing analytical template families that account for the inspiral-merger-ringdown phases of the binary.

    2011-05-01

    Full Text Available Are Quebec’s future teachers ready to integrate information and communication technologies (ICT into the scholastic context? To answer this question, a study was conducted with some 2,065 future teachers, 410 associate professors and 90 supervisors of teaching practices from nine French-speaking Quebec universities offering a beginning teacher-training program. The results show that these prospective teachers have access to the equipment needed to become familiar with ICT, and that they use basic technology skills well. Furthermore, the data collected revealed that teachers in training use ICT regularly and reflectively to plan their classes, communicate, search for information, prepare didactic materials, solve problems, or improve themselves professionally. Although the profile shown is promising, the study results also indicate a very low proportion of future teachers who use ICT in the classroom.

    Full Text Available Emerging technologies in the experimental sciences have opened the way for large-scale experiments. Such experiments generate ever growing amounts of data from which researchers need to extract relevant pieces for subsequent analysis. R offers a great environment for statistical analysis. However, due to the diversity of possible data sources and formats, data preprocessing and import can be time consuming especially with data that require user interaction such as editing, filtering or formatting. Writing a code for these tasks can be time-consuming, error prone and rather complex. We present speedR, an R-package for interactive data import, filtering and code generation in order to address these needs. Using speedR, researchers can import new data, make basic corrections, examine current R session objects, open them in the speedR environment for filtering (subsetting, put the filtered data back into R, and even create new R functions with applied import and filtering constraints to speed up their productivity.

    Direct electron transfer (DET) to proteins is of considerable interest for the development of biosensors and bioelectrocatalysts. While protein structure is mainly used as a method of attaching the protein to the electrode surface, we employed bioinformatics analysis to predict the suitable orientation of the enzymes to promote DET. Structure similarity and secondary structure prediction were combined underlying localized amino-acids able to direct one of the enzyme's electron relays toward the electrode surface by creating a suitable bioelectrocatalytic nanostructure. The electro-polymerization of pyrene pyrrole onto a fluorine-doped tin oxide (FTO) electrode allowed the targeted orientation of the formate dehydrogenase enzyme from Rhodobacter capsulatus (RcFDH) by means of hydrophobic interactions. Its electron relays were directed to the FTO surface, thus promoting DET. The reduction of nicotinamide adenine dinucleotide (NAD(+)) generating a maximum current density of 1μAcm(-2) with 10mM NAD(+) leads to a turnover number of 0.09electron/s/molRcFDH. This work represents a practical approach to evaluate electrode surface modification strategies in order to create valuable bioelectrocatalysts. PMID:27156017

    2013-06-01

    The interdependence between vehicle and engine evolution and increasing requirements for fuel quality has led to widespread use of premium grade fuels. These qualities are increasingly sold in fuel stations and by dealers. They may even be perceived as ''standard'' quality. Classical ''Norm Qualities'' become ever less relevant for engine powered equipment users. Alongside these ''premium qualities'', customized additives for application specific solutions in the service area are an additional and more growing market. This includes the use of special fuels designed for the optimal operation of vehicle fleets. These applications open significant additional market potential. Some representative applications, in the Diesel as well as in the LPG-market, will be shown as examples of successful service provided for niche markets. (orig.)

Higher levels of polyphenol oxidase (PPO, phenylalanine ammonia-lyase (PAL, ß-1, 3-glucanase (PR-2 and phenolics were observed in roots and shoots of resistant cultivar than that of susceptible cultivar on treatment with elicitors and pathogen. However, no major changes were observed in susceptible cultivar after the treatments. ß-1, 3-glucanase is constitutively present and is further induced in roots and shoots of resistant cultivar by F. oxysporum f. sp. ciceri. No induction of ß-1, 3-glucanase was observed in susceptible cultivar. The structural changes during disease progression were observed by histochemical staining. However, the pathogen invasion was more in susceptible cultivar compared with resistant cultivar. Further, the invasion was restricted in roots of resistant cultivar treated with SA. These results suggest that induction of defense proteins and accumulation of phenolics might have contributed to restrict the invasion of F.oxysporum f. sp. ciceri, in resistant cultivar ICCV10.

    Plant seeds contain a number of proteins which play important roles in the protection and the process of germination of seeds. We have isolated and purified a 25 kDa protein from Kabuli Chana (Cicer arietinum L., Chickpea-white, CW-25). The CW-25 protein was crystallized using 0.5 M magnesium acetate, 0.1 M sodium cacodylate and 20 % (w/v) polyethylene glycol 8000, pH 6.5. The crystals of CW-25 belonged to space group P3 with unit cell dimensions, a = b = 80.5 Å, and c = 69.2 Å. The structure of CW-25 was determined using molecular replacement method and refined to an R factor of 0.152. The buried surface area between two molecules was found to be approximately 653 Å(2) indicating the formation of a weak homodimer. The polypeptide chain of CW-25 adopted a hemopexin-fold with four-bladed β-propellers. The structure formed a central tunnel-like architecture. A magnesium ion was observed in the centre of the tunnel. It was located at distances varying between 2.3 and 2.7 Å from five oxygen atoms of which four were backbone oxygen atoms belonging to residues, Asn7, Asp65, Asp121 and Asp174 while the fifth oxygen atom, O(δ1) was from the side chain of Asn7. The approximate length of the tunnel was 30 Å. Furthermore, a series of carbonyl oxygen atoms were present along the internal face of the tunnel. The diameter of the tunnel varied from 4.6 to 6.2 Å. The diameter and chemical environment of the tunnel clearly indicated that it might be used for the transport of various metal ions across the molecule. PMID:26242869

  4. Indigenous technology development and standardization of the process for obtaining ready to use sterile sodium pertechnetate-Tc-99m solution from Geltech generator

    International Nuclear Information System (INIS)

    The indigenous design and technology development for processing large scale zirconium molybdate-Mo-99 (ZrMo-99) Geltech generator was successfully commissioned in Board of Radiation and Isotope Technology (BRIT), India, in 2006. The generator production facility comprises of four shielded plant facilities equipped with tongs and special process gadgets amenable for remote operations for radiochemical processing of ZrMo-99 gel. Over 2800 Geltech generators have been processed and supplied to user hospitals during the period 2006-2013. Geltech generator supplied by BRIT was initially not sterile. Simple elution of 99mTc is performed by a sterile evacuated vial with sterile and pyrogen free 0.9% NaCl solution to obtain sodium (99mTc) pertechnetate solution. A special type online 0.22 μm membrane filter has been identified and adapted in Geltech generator. The online filtration of 99mTc from Geltech generator; thus, provided sterile 99mTc sodium pertechnetate solution. Generators assembled with modified filter assembly were supplied to local hospital in Mumbai (Radiation Medicine Centre (RMC) and S.G.S. Medical College and KEM Hospital) and excellent performances were reported by users. (author)

    A rapid screening method for the investigation of plasma-induced chemical modifications was developed by analyzing cysteine using Fourier Transform Infrared (FTIR) spectroscopy. Cysteine is a key amino acid in proteins due to the presence of a thiol group which provides unique structural features by offering the possibility to form disulfide bonds. Its chemical composition makes cysteine a well-suited model for the investigation of plasma-induced modifications at three functional groups—the amino, the carboxyl and the thiol group—all highly abundant in proteins. FTIR spectroscopy is present in most physical laboratories and offers a fast way to assess changes in the chemical composition of cysteine substrates due to plasma treatment and to compare different treatment conditions or plasma sources with each other. Significant changes in the fingerprint spectra of cysteine samples treated with a dielectric barrier discharge (DBD) compared to untreated controls were observed using a FTIR spectrometer. The loss of the thiol signal and the simultaneous increase of bands originating from oxidized sulfur and nitrogen species indicate that the thiol group of cysteine is modified by reactive oxygen and nitrogen species during DBD treatment. Furthermore, other plasma-induced modifications, such as changes of the amino and carbonyl groups, could be observed. Complementary mass spectrometry measurements confirmed these results.

    The objective of this study was to evaluate the effect of an edible coating combined with modified atmosphere (MA; 60% O2, 30% CO2, and 10% N2) packaging and gamma irradiation on the microbiological stability and physicochemical quality of minimally processed carrots. A coating based on calcium caseinate and whey protein isolates was used. Coated and uncoated peeled minicarrots were packed under the MA or air (78.1% N2, 20.9% O2, and 0.036% CO2), irradiated at 0.5 or 1 kGy, and stored at 4 +/- 1 degrees C for 21 days. Samples were evaluated periodically for aerobic plates counts (APCs) and physicochemical properties (firmness, white discoloration, and whiteness index). Gamma irradiation did not significantly affect the physicochemical properties of the carrots (P > 0.05). Microbiological analysis revealed that for uncoated carrots irradiation at 0.5 and 1 kGy under air and MA reduced the APCs by 3.5 and 4 log CFU/g and by 4 and 4.5 log CFU/g, respectively. For coated carrots, irradiation at 0.5 and 1 kGy under air and MA reduced the APCs by 4 and 4.5 log CFU/g and by 3 and 4.25 log CFU/g, respectively. The coating was able to protect carrots against dehydration during storage under air. Coating and irradiation at 1 kGy were also able to protect carrot firmness during storage under air. MA packaging retarded whitening of uncoated carrots but had a detrimental effect on firmness. The edible coating used in this study did not significantly inhibit (P > 0.05) microbial growth on carrots. PMID:15726981

    Cryopreservation is generally performed on cells in suspension. In the case of adherent cells such as hepatocytes, a loss of their ability to attach is a more serious problem than a decreased viability after cryopreservation. We herein report a novel technology of direct in situ cryopreservation of cells cultured on collagen vitrigel membranes, which have excellent mechanical strength and can be easily handled by tweezers even when coated with cultured cells. Rat primary hepatocytes, mitomycin C-treated mouse fibroblasts (feeder cells for ES cells), and mouse ES cells on the feeder cells were cultured on collagen vitrigel membranes for 1 day. The membranes with cells attached were then plucked up from the dish, soaked in cryopreservation medium containing 10% dimethyl sulfoxide, frozen using a controlled-rate freezer, and transferred to liquid nitrogen. The cells cultured on plastic cell culture dishes were also frozen as controls. After storage in liquid nitrogen for periods from 1 week to 3 months, the cryopreserved membranes with the cells still attached were thawed by adding warmed culture medium. Cell viability estimated by morphology and functional staining with calcein showed significant improvement in comparison to cells cryopreserved without the collagen vitrigel membrane. The recoveries of living cells after cryopreservation were 26.7%, 76.2%, and 58.6% for rat hepatocytes, mitomycin C-treated mouse fibroblasts, and mouse ES cells on collagen vitrigel membranes, respectively. In contrast, essentially no cells at all remained on the plastic cell culture dishes after thawing. Because adherent cell storage under these conditions is very convenient, the use of this technique employing collagen vitrigel membranes should be generally applicable to the cryopreservation of adherent cells that are otherwise problematic to store as frozen stocks.

    Full Text Available E-learning is likely to be an increasingly important element in teaching agriculture and related subjects at universities in Sub-Saharan Africa. The purpose of this study was to explore the factors involved in determining the readiness and intention to adopt e-learning by faculty members at member institutions of the African Network for Agriculture, Agroforestry and Natural Resources Education (ANAFE. The study was based on the decomposed theory of planned behavior (DTPB to predict intentions on the use of e-learning. DTPB draws on constructs influencing the attitude to use technology from two frequently investigated models in this area, that is, the theory of planned behavior (TPB and the technology acceptance model (TAM. Valid responses were collected from 70 faculty members with a survey questionnaire. Validated scales from previous research were used to measure the variables of interest. The results revealed that the majority of the respondents have only limited access to ICT infrastructure and support services. However, they perceived e-learning to be very useful in general and to have the potential to enhance their teaching-related activities.

  11. A new technique for the preparation of ready-to-use macroaggregated albumin (MAA) kits to be labelled with sup(99m)Tc for lung scanning

    International Nuclear Information System (INIS)

    Kits were developed for the sterile labelling of macroaggregated albumin (human) with sup(99m)Tc. 0.4 mL of 20% HSA, 1 mL of SnCl2.2H2O containing 5 mg and 1.1 mL of 0.9% NaCl were sonified for 10 min. The pH was adjusted with phosphate buffer to 5.5 after the addition of 1 mL of 5% Tween-80. The solution was heated with stirring for 10 min at 800C for aggregation and 1.0 mL portions were placed in 10 mL vials for lyophilization. The contents of single reaction vials were reacted with sup(99m)Tc and the radiochemical yield determined (higher than 98%). The MAA kits were stable and the stability of [sup(99m)Tc]-MAA was followed for 4.5 h. Lung uptake in mice was determined to be about 98.5%. The preparation of [sup(99m)Tc]-MAA was performed in a single step process and excellent human lung scans were obtained. (author)

    Full Text Available Identification of weed species with allelopathic potential and characterization of their adverse effects against associated crops is required for better understanding of weed-crop interactions. Phytotoxic activity of Euphorbia dracunculoides Lam. on germination and seedling growth of chickpea (Cicer arietinum L. and wheat (Triticum aestivum L. was investigated under controlled conditions. Two separate studies were done with each of four organic solvent fractions (n-hexane, chloroform, ethylacetate, 1-butanol and crude aqueous (1:10 and 1:20 whole plant fractions of E. dracunculoides using distilled water and 0.05% (v/v dimethyl sulfoxide (DMSO as control. Different aqueous and organic fractions of E. dracunculoides had a significant bearing on germination attributes and seedling growth that varied among tested species. The final germination percentage of wheat remained unaffected; nevertheless, root and shoot elongation and biomass accumulation in these parts were significantly retarded. Aqueous fractions appeared more phytotoxic than organic fractions and suppressed chickpea germination by 35-53%. These aqueous fractions also reduced root (64-75% and 33-34% and shoot (18-62% and 21% length and root (32-33% and 42-46% and shoot (7-32% and 80-84% dry weight of wheat and chickpea, respectively. Among organic fractions, n-hexane was more suppressive to test species. Chromatographic analysis revealed the presence of four phytotoxins, furoic, p-coumaric, syringic, and caffeic acids, in aqueous whole plant (1:10 fractions. This study determined the phytotoxic allelopathic activity of E. dracunculoides against wheat and chickpea.Se requiere la identificación de especies de malezas con potencial alelopático y la caracterización de sus efectos adversos en contra de los cultivos asociados para una mejor comprensión de las interacciones cultivos-malezas.

    Full Text Available Since new fungicides are scarce in the market and because of environmental problems, researchers are now emphasizing other alternatives, such as the genetic potential of plants, resistance against pathogens, and the use of biotic and abiotic agents to develop induced or acquired resistance. We investigated the role of resistance-inducing substances (chemicals and plant extracts in three chickpea cvs. C-44, Pb-91, and Bittle-98 in field experiments against Ascochyta blight disease. These cultivars were selected on the basis of better yield potential shown in previous experiments. Aqueous solution of salicylic acid (SA at 0.5, 1.0, and 1.5 mM; acibenzolar-S-methyl (Bion®, ASM at 0.4, 0.8, and 1.2 mM; and KOH at 25, 50, and 75 mM were applied, whereas Azadirachta indica A. Juss., Datura metel L., and Allium sativum L. plant extracts were applied at 5, 10, and 15%. Disease reduction data was recorded at different intervals from 4 to 14 d after being induced and inoculated with the pathogen. Overall results revealed that significant disease reduction (79.3% was provided by ASM in the cv. C-44 at 1.2 mM compared with SA, whereas the least significant was KOH. Maximum disease reduction (43.5% against disease in the plant extracts was observed by applying A. indica leaf extract, but D. metel and A. sativum extracts were not effective. Our findings suggest that enhancing resistance before infecting chickpea plants could be an innovative control method for Ascochyta blight of chickpea.Debido a la escasez de nuevos fungicidas en el mercado y problemas ambientales, los investigadores están ahora enfatizando otras alternativas, tales como potencial genético de las plantas, resistencia contra patógenos y uso de agentes bióticos y abióticos para el desarrollo de resistencia inducida y adquirida.

    Full Text Available No presente estudo procedeu-se ao isolamento e caracterização da fração globulina majoritária (11 S de grão-de-bico, var. IAC-Marrocos. A globulina majoritária extraída foi isolada por cromatografia de filtração em gel e de troca-iônica mostrando apenas uma banda de proteína na eletroforese em gel de poliacrilamida. A globulina majoritária, após passagem em coluna de Sephadex, revelou duas bandas protéicas de 55 e 52,5kDa e três bandas menores em gel de poliacrilamida dodecilsulfato de sódio. Na presença de 2-mercaptoetanol 6 polipeptídios na faixa de 18 a 42kDa foram revelados na eletroforese. A globulina isolada foi submetida à ação da tripsina e quimotripsina onde a forma nativa mostrou-se resistente à ação enzimática enquanto o aquecimento (96 e 121°C/15min não foi suficiente para aumentar a susceptibilidade à hidrólise, significativamente. Adição de NaCl 0,3M levou a um aumento da estabilidade estrutural com menor susceptibilidade à digestão proteolítica, fato em parte perdido com o aquecimento. As hidrólises foram acompanhadas por eletroforese em gel de poliacrilamida dodecilsulfato de sódio.The isolation and characterization of the major globulin fraction (11 S from Chickpea, vc IAC-Marrocos, were evaluated. The major globulin was extracted, isolated by gel filtration and ion-exchange chromatography showing only one protein band on PAGE. The globulin, after Sephadex elution, revealed two protein bands of 55 and 52.5kDa and three minor bands on SDS-PAGE. In the presence of 2-mercaptoethanol six polypeptides were revealed on SDS-PAGE in the range of 18 to 42kDa. The isolated native globulin shown to be resistant to trypsin and chymotrypsin however heating at 96 and 121ºC/15min was not sufficient to increase the hydrolysis significantly. The proteolytic susceptibility of the enzymes was reduced by 0.3M NaCl addition at the assay. The salt concentration was sufficient to stabilize the native protein

  18. The influence of antimicrobial compounds or coating and modified atmosphere packaging on radiation sensitivity of Listeria monocytogenes and Listeria innocua on quality maintenance of ready-to-use carrots (Daucus carota)

    International Nuclear Information System (INIS)

    An edible coating based on caseinate and whey protein combined with modified atmosphere packaging (MAP): (60% O2; 30% CO2; 10% N2) and gamma irradiation on the microbiological stability and physico-chemical quality of minimally processed carrots (Daucus carota L.) was evaluated. Carrots were irradiated at 0.5 or 1 kGy and stored at 4 ± 1 deg. C for 21 days. Results showed that gamma irradiation did not affect significantly (p > 0.05) the physico-chemical properties of the carrots. Microbiological analysis showed that for uncoated carrots a dose of 0.5 and 1 kGy applied under air and MAP reduced, respectively, by 3.5 and 4 log CFU/g and by 4 and 4.5 log CFU/g the content in aerobic plate count (APC). For coated carrots a dose of 0.5 and 1 kGy applied under air and MAP reduced, respectively, by 4 and 4.5 log CFU/g and by 3 and 4.25 log CFU/g the content of APC. The coating was able to protect carrots against dehydration during storage under air. Coating and irradiation treatment at 1 kGy were also able to protect the firmness during storage under air. MAP retarded whitening of uncoated carrots, but this treatment had a detrimental effect on the firmness. Processed carrots were also coated with caseinate based coating containing spice extracts or of antimicrobial compounds present in spices and irradiated at doses from 0.07 to 2.4 kGy to evaluate the radiosensitization of Listeria monocytogenes HPB 2812 serovar 1/2a (106 CFU/g). The dose (D10) required to reduce L. monocytogenes population by 1 log was 0.36 kGy for samples packed under air and 0.17 kGy for those packed under MAP. In presence of trans-cinnamaldehyde, Spanish oregano, winter savory and Chinese cinnamon, the results showed that these active compounds had an effect on the irradiation sensitivity of bacterium in reducing L. monocytogenes population in carrots. The most efficient compound was trans-cinnamaldehyde where a mean increase of the relative radiation sensitivity of 3.8 times was observed for both atmospheres, as compared to the control. The effect of an antimicrobial edible coating containing Trans-cinnamaldehyde combined with MAP and gamma irradiation showed that the coating was able to reduce by 1.29 logs CFU/g the content of L. innocua in carrots packed under air after 21 days of storage whereas when packed under MAP, a 1.08 log CFU/g reduction was observed only after seven days of storage. Also, after seven days of storage, any L. innocua was detected in samples treated at 0.5 kGy under air or in samples treated at 0.25 kGy under MAP. A complete inhibition of L. innocua was also observed during all storage period in uncoated and coated samples treated at 0.5 kGy under MAP. These results revealed that the combination of irradiation, antimicrobial coating and MAP conditions played an important role in the bacterial radiosensitization. (author)

    Full Text Available To compensate for stress imposed by salinity, biofilm formation and exopolysaccharide production are significant strategies of salt tolerant bacteria to assist metabolism. We hypothesized that two previously isolated salt-tolerant strains Halomonas variabilis (HT1 and Planococcus rifietoensis (RT4 have an ability to improve plant growth, These strains can form biofilm and accumulate exopolysacharides at increasing salt stress. These results showed that bacteria might be involved in developing microbial communities under salt stress and helpful in colonizing of bacterial strains to plant roots and soil particles. Eventually, it can add to the plant growth and soil structure. We investigated the comparative effect of exopolysacharide and biofilm formation in two bacterial strains Halomonas variabilis (HT1 and Planococcus rifietoensis (RT4 in response to varying salt stress. We found that biofilm formation and exopolysaccharide accumulation increased at higher salinity. To check the effect of bacterial inoculation on the plant (Cicer arietinum Var. CM-98 growth and soil aggregation, pot experiment was conducted by growing seedlings under salt stress. Inoculation of both strains increased plant growth at elevated salt stress. Weight of soil aggregates attached with roots and present in soil were added at higher salt concentrations compared to untreated controls. Soil aggregation was higher at plant roots under salinity. These results suggest the feasibility of using above strains in improving plant growth and soil fertility under salinity.

    Phytic acid and raffinose series oligosaccharides (RFOs) have anti-nutritional properties where phytic acid chelates minerals and reduces their bioavailability to humans and other animals, and RFOs cause flatulence. Both phytic acid and RFOs cannot be digested by monogastric animals and are released as pollutant-wastes.

    International Nuclear Information System (INIS)

    The crystallization and characterization of a lectin isolated and purified from C. arietinum and possessing complex sugar specificity is reported. The lectin isolated from mature seeds of Cicer arietinum (CAL) agglutinates pronase-treated rabbit and human erythrocytes and its haemagglutination activity is inhibited by fetuin and desialated fetuin but not by simple monosaccharides or oligosaccharides. The purified lectin is a dimer of molecular weight 43 000 Da composed of two identical subunits (MW 21 500), as confirmed by SDS–PAGE. The lectin has been crystallized using the hanging-drop vapour-diffusion method at 295 K over a well solution containing 0.2 M sodium acetate, 0.1 M sodium phosphate buffer pH 6.5 and 14%(w/v) polyethylene glycol 8000. The triangular prism-shaped crystals belong to space group R3 and have unit-cell parameters a = b = 81.2, c = 69.4 Å. The diffraction data are 93.8% complete to 2.3 Å Bragg spacing with an Rmerge of 0.103

    In the present experiment the seeds of Cicer arietinum (L.) cv. Uday were inoculated with specific Rhizobium grown in sandy loam soil and were allowed to grow for 15 days. At this stage, the seedlings were supplied with 0, 50, 100 or 150 {mu}M of cadmium in the form of cadmium chloride and sprayed with 0.01 {mu}M of 28-homobrassinolide (HBL) at 30-day stage. The data indicated that plant fresh and dry mass, number of nodules, their fresh and dry mass, leghemoglobin content, nitrogen and carbohydrate content in the nodules, leaf chlorophyll content, nitrate reductase and carbonic anhydrase activities decreased proportionately with the increasing concentrations of cadmium but the content of proline and the activities of catalase, peroxidase and superoxide dismutase increased. The ill effect, generated by cadmium, was overcome if the stressed plants were sprayed with HBL. - The cadmium toxicity can be overcome by the foliar application of 28-homobrassinolide.

    Kunitz proteinase inhibitors in legumes have mainly been described as defence and storage proteins. Here, we report a Kunitz trypsin inhibitor, encoded by the CaTPI-1 gene from Cicer arietinum. The transcription of this gene mainly occurs in seedling vegetative organs, and is affected by the light and growth stages. The recombinant TPI-1 protein expressed in E. coli was seen to be an efficient inhibitor of trypsin. After the generation of polyclonal antibodies against recombinant TPI-1 protein, the protein was located in the cell wall of elongating epicotyls and radicles by Western-blot experiments, in agreement with the transcription pattern. These results, together with the fact that both CaTPI-1 mRNA and protein levels decreased with epicotyl growth, suggest a possible role in the elongation of seedling epicotyls and radicles. Immunolocalization analyses of the TPI-1 protein indicated that it is abundant in the cell walls of both immature primary xylem cells and surrounding parenchyma cells. This location has led us to explore potential functions for TPI-1 protein in vascular tissue during seedling elongation. PMID:17226027

    Twenty-nine mature raw varieties of grain legume seeds (chickpeas, field peas, faba beans, common vetch and lupins) produced in Europe were investigated for their phenolic profile by means of high performance liquid chromatography coupled to diode array detection (HPLC-DAD). To the best of our knowledge, this study reported for the first time the phenolic composition of mature raw seeds of chickpea type Desi, field pea and common vetch. Phenolic acids were predominant compounds in chickpeas, field peas and common vetch compared to flavonoids, whereas the opposite was observed for lupin seeds. Yellow lupins presented the highest levels of total phenolic compounds followed by narrow-leafed lupins (in average 960 and 679mg/kg, dry basis, respectively), whereas Kabuli chickpeas got the lowest ones (in average 47mg/kg, dry basis). Principal component analysis revealed that flavones and total levels of phenolic compounds were responsible for nearly 51% of total data variability. PMID:27542465

    Full Text Available The present study was carried out to estimate growth pattern and examine the best ARIMA model to efficiently forecasting pigeon pea, chickpea and field pea pulse production in Bangladesh. It appeared that the time series data for pigeon pea, chickpea and field pea were 1st order homogenous stationary. Two types of models namely Box-Jenkins type Autoregressive Integrated Moving Average (ARIMA and deterministic type growth models, are examined to identify the best forecasting models for pigeon pea, chickpea and field pea pulse production in Bangladesh. The study revealed that the best models were ARIMA (1, 1 and 1, ARIMA (0, 1 and 0 and ARIMA (1, 1 and 3 for pigeon pea, chickpea and field pea pulse production, respectively. Among the deterministic type growth models, the cubic model is best for pigeon pea, chickpea and field pea pulse production. The analysis indicated that short-term forecasts were more efficient for ARIMA models compared to the deterministic models. The production uncertainty of pulse could be minimized if production were forecasted well and necessary steps were taken against losses. The findings of this study would be more useful for policy makers, researchers as well as producers in order to forecast future national pulse production more accurately in the short run.

    Multivariate screening methods are increasingly being implemented but there is no worldwide harmonized criterion for their validation. This study contributes to establish protocols for validating these methodologies. We propose the following strategy: (1) Establish the multivariate classification model and use receiver operating characteristic (ROC) curves to optimize the significance level (α) for setting the model's boundaries. (2) Evaluate the performance parameter from the contingency table results and performance characteristic curves (PCC curves). The adulteration of hazelnut paste with almond paste and chickpea flour has been used as a case study. Samples were analyzed by infrared (IR) spectroscopy and the multivariate classification technique used was soft independent modeling of class analogies (SIMCA). The ROC study showed that the optimal α value for setting the SIMCA boundaries was 0.03 in both cases. The sensitivity value was 93%, specificity 100% for almond and 98% for chickpea, and efficiency 97% for almond and 93% for chickpea. PMID:24832991

    The study was conducted to prepare supplemented biscuits which could be used as nutritive snacks for malnourished children. Biscuits were prepared by supplementing chickpea and oat in patent flour (fine flour) with different ratio (5%, 10%, 15% and 20 %). Biscuits with no supplementation were kept as control treatment. Chemical and sensory evaluation of supplemented biscuits was carried out. An increase in nutritive values have been observed with an increase in supplementation level. Proximate analysis shows that T/sub 7/ and T/sub 8/ get the highest values for protein, zinc and iron. Results of all treatments were in acceptable range regarding sensory evaluation. These results indicate that biscuits can be successfully supplemented with chickpea and oat. According to sensory evaluation, biscuits containing 20% chickpea and 15% oat were found to be the best among all treatments and could be a potential composition for preparing high energy biscuits for malnourished areas of Pakistan.

    The objective of this study was to compare the quality of legume cakes baked in microwave-infrared combination (MW-IR) oven with conventional oven. Legume cake formulations were developed by replacing 10 % wheat flour by lentil, chickpea and pea flour. As a control, wheat flour containing cakes were used. Weight loss, specific volume, texture, color, gelatinization degree, macro and micro-structure of cakes were investigated. MW-IR baked cakes had higher specific volume, weight loss and crust color change and lower hardness values than conventionally baked cakes. Larger pores were observed in MW-IR baked cakes according to scanning electron microscope (SEM) images. Pea flour giving the hardest structure, lowest specific volume and gelatinization degree was determined to be the least acceptable legume flour. On the other hand, lentil and chickpea flour containing cakes had the softest structure and highest specific volume showing that lentil and chickpea flour can be used to produce functional cakes.

    Molecular markers are the most powerful genomic tools to increase the efficiency and precision of breeding practices for crop improvement. Progress in the development of genomic resources in the leading legume crops of the semi-arid tropics (SAT), namely, chickpea (Cicer arietinum), pigeonpea (Cajanus cajan) and groundnut (Arachis hypogaea), as compared to other crop species like cereals, has been very slow. With the advances in next-generation sequencing (NGS) and high-throughput (HTP) genotyping methods, there is a shift in development of genomic resources including molecular markers in these crops. For instance, 2,000 to 3,000 novel simple sequence repeats (SSR) markers have been developed each for chickpea, pigeonpea and groundnut. Based on Sanger, 454/FLX and Illumina transcript reads, transcriptome assemblies have been developed for chickpea (44,845 transcript assembly contigs, or TACs) and pigeonpea (21,434 TACs). Illumina sequencing of some parental genotypes of mapping populations has resulted in the development of 120 million reads for chickpea and 128.9 million reads for pigeonpea. Alignment of these Illumina reads with respective transcriptome assemblies have provided > 10,000 SNPs each in chickpea and pigeonpea. A variety of SNP genotyping platforms including GoldenGate, VeraCode and Competitive Allele Specific PCR (KASPar) assays have been developed in chickpea and pigeonpea. By using above resources, the first-generation or comprehensive genetic maps have been developed in the three legume speciesmentioned above. Analysis of phenotyping data together with genotyping data has provided candidate markers for drought-tolerance-related root traits in chickpea, resistance to foliar diseases in groundnut and sterility mosaic disease (SMD) and fertility restoration in pigeonpea. Together with these trait-associated markers along with those already available, molecular breeding programmes have been initiated for enhancing drought tolerance, resistance to

    Full Text Available The effects of yellow lentil flour, chickpea flour and their mixtures as batters on deep-fried fish balls were evaluated in the present study. The pH levels, viscosities and adhesion degrees of the batters and yields, frying loss, penetrometer values, diameters, moisture, oil content and sensorial properties of fish balls were determined for the different mixtures and frying temperatures. Yellow lentil flour, chickpea flour and their mixtures increased the quality of the battered fish balls after frying. Yellow lentil flour increased the yield and moisture values and decreased the frying loss and penetrometer values during deep-frying. Chickpea flour had better sensory properties in comparison to the control and yellow lentil flour. Frying temperatures generally did not affect the quality criteria. Only, low temperatures decreased the moisture loss from the coated fish balls during deep-frying. In conclusion, yellow lentil flour and chickpea flour were suggested as the batter materials to be used on fish balls.

    2015-06-01

    Full Text Available There are several economically important grain legumes including chickpea that play significant role in nutrition of the rural and urban poor in developing world. Plants are subjected to a large number of stresses that may interfere with the normal growth and development. The model legumes are being developed as experimental systems to study a number of key biological questions using molecular tools including genomics and proteomics. Most of the functional genomics approaches rely upon the highthroughput transformation system useful for studying various gene identification strategies. The difficulty to transform a plant varies from species to species in legumes. There is limited success in exchange of the desirable characters by the classical and modern breeding technologies, in important pulse crop chickpea and biotechnological tools like plant tissue culture and genetic transformation techniques have emerged as a potential supplement. The major bottleneck is requirement of an in vitro manipulation of leguminosae members and the availability of reproducible, efficient and better plant regeneration methods. The regeneration and transformation of legumes particularly chickpea suffers due to recalcitrant nature towards rooting and transplantation of the in vitro regenerated plants. This becomes a limiting factor for the application of this technology towards designated mandate of crop improvement programs. This article discusses the hurdles and strategies for transformation of legumes in general and chickpea in particular.

    The Heliothinae complex in Argentina encompasses Helicoverpa gelotopoeon (Dyar), Helicoverpa zea (Boddie), Helicoverpa armigera (Hübner), and Chloridea virescens (Fabricius). In Tucumán, the native species H. gelotopoeon is one of the most voracious soybean pests and also affects cotton and chickpea, even more in soybean-chickpea succession cropping systems. Differentiation of the Heliothinae complex in the egg, larva, and pupa stages is difficult. Therefore, the observation of the adult wing pattern design and male genitalia is useful to differentiate species. The objective of this study was to identify the species of the Heliothinae complex, determine population fluctuations of the Heliothinae complex in soybean and chickpea crops using male moths collected in pheromone traps in Tucuman province, and update the geographical distribution of H. armigera in Argentina. The species found were H. gelotopoeon, H. armigera, H. zea, and C. virescens. Regardless of province, county, crop, and year, the predominant species was H. gelotopoeon. Considering the population dynamics of H. gelotopoeon and H. armigera in chickpea and soybean crops, H. gelotopoeon was the most abundant species in both crops, in all years sampled, and the differences registered were significant. On the other hand, according to the Sistema Nacional Argentino de Vigilancia y Monitoreo de Plagas (SINAVIMO) database and our collections, H. armigera was recorded in eight provinces and 20 counties of Argentina, and its larvae were found on soybean, chickpea, sunflower crops and spiny plumeless thistle (Carduus acanthoides).

    2015-10-01

    The capability of different gluten-free (GF) basic formulations made of flour (rice, amaranth and chickpea) and starch (corn and cassava) blends, to make machinable and viscoelastic GF-doughs in absence/presence of single hydrocolloids (guar gum, locust bean and psyllium fibre), proteins (milk and egg white) and surfactants (neutral, anionic and vegetable oil) have been investigated. Macroscopic (high deformation) and macromolecular (small deformation) mechanical, viscometric (gelatinization, pasting, gelling) and thermal (gelatinization, melting, retrogradation) approaches were performed on the different matrices in order to (a) identify similarities and differences in GF-doughs in terms of a small number of rheological and thermal analytical parameters according to the formulations and (b) to assess single and interactive effects of basic ingredients and additives on GF-dough performance to achieve GF-flat breads. Larger values for the static and dynamic mechanical characteristics and higher viscometric profiles during both cooking and cooling corresponded to doughs formulated with guar gum and Psyllium fibre added to rice flour/starch and rice flour/corn starch/chickpea flour, while surfactant- and protein-formulated GF-doughs added to rice flour/starch/amaranth flour based GF-doughs exhibited intermediate and lower values for the mechanical parameters and poorer viscometric profiles. In addition, additive-free formulations exhibited higher values for the temperature of both gelatinization and retrogradation and lower enthalpies for the thermal transitions. Single addition of 10% of either chickpea flour or amaranth flour to rice flour/starch blends provided a large GF-dough hardening effect in presence of corn starch and an intermediate effect in presence of cassava starch (chickpea), and an intermediate reinforcement of GF-dough regardless the source of starch (amaranth). At macromolecular level, both chickpea and amaranth flours, singly added, determined

    Drought is one of the most important abiotic stresses that adversely affect plant growth and yield potential. However, some drought resistant rhizosphere competent bacteria are known to improve plant health and promote growth during abiotic stresses. Present study showed the role of Pseudomonas putida MTCC5279 (RA) in ameliorating drought stress on cv. BG-362 (desi) and cv. BG-1003 (kabuli) chickpea cultivars under in vitro and green house conditions. Polyethylene glycol-induced drought stress severely affected seed germination in both cultivars which was considerably improved on RA-inoculation. Drought stress significantly affected various growth parameters, water status, membrane integrity, osmolyte accumulation, ROS scavenging ability and stress-responsive gene expressions, which were positively modulated upon application of RA in both chickpea cultivars. Quantitative real-time (qRT)-PCR analysis showed differential expression of genes involved in transcription activation (DREB1A and NAC1), stress response (LEA and DHN), ROS scavenging (CAT, APX, GST), ethylene biosynthesis (ACO and ACS), salicylic acid (PR1) and jasmonate (MYC2) signalling in both chickpea cultivars exposed to drought stress and recovery in the presence or absence of RA. The observations imply that RA confers drought tolerance in chickpea by altering various physical, physiological and biochemical parameters, as well as by modulating differential expression of at least 11 stress-responsive genes. To the best of our knowledge, this is the first report on detailed analysis of plant growth promotion and stress alleviation in one month old desi and kabuli chickpea subjected to drought stress for 0, 1, 3 and 7 days and recovery in the presence of a PGPR.

    Full Text Available Screening and agronomic performances of 45 chickpea genotypes (Cicer arietinum L. submitted to a limited hydrous pattern. In Tunisia, chickpea (Cicer arietinum L. is one of the most important legume grain crops. It is conducted during two periods of the year either as winter crop or as spring crop. The last type has the advantage to occupy the soil in a short period of time (February to June. However, it exposes plants to water stress. Consequently, vegetative development and grain yield are negatively affected in quantity and quality. In order to study plant reactions to drought conditions, 45 genotypes of chickpea (C. arietinum were tested in delayed spring culture under a water stressed treatment. A field trial was carried out in the region of Chott Mariem belonging to the semi-arid superior. The drought stress is established at the beginning of flowering stage and was accentuated during the grain filling and the seed maturity phases. To evaluate the chickpea genotypes stress tolerance, parameters related to the vegetative development, the seed yield, the water use efficiency and the thermal duration were measured. The analysis of the grain yield and its components revealed that there is a biological diversity among the genotypes tested. The 45 accessions can be divided into three groups. The first one is composed of ‘Kabuli’ chickpea genotypes which are sensitive to drought stress. They are not appropriate for spring crop in semi-arid regions. The second group is composed of genotypes, of which two are of ‘Dési’ type, that are tolerant to drought stress and can be recommended for a spring crop in the superior semi-arid zones. The last group of genotypes is moderately sensitive to drought stress. They can be led as spring crop in the semi-arid superior zones with complementary irrigations.

    Pulses are low glycaemic foods; however, their effect on satiation is unknown. The objective was to determine the effects of an ad libitum pulse meal on food intake (FI), appetite and blood glucose (BG) before and after a test meal (4 h later) and on FI at the test meal. Males (n 24, 22·8 kg/m2) received one of four treatments or control. The pulse treatments contained pasta and tomato sauce and 44 % of energy from: (1) chickpeas, (2) lentils, (3) navy beans or (4) yellow peas. The control was pasta and tomato sauce (pasta and sauce). FI (satiation) was measured at the treatment meal (0-20 min) and at an ad libitum pizza meal 4 h later. BG and appetite were measured from 0 to 340 min. At the treatment meal, lentils led to lower FI compared to chickpeas and pasta and sauce, whereas navy beans led to lower FI compared to chickpeas. Also, lentils led to lower cumulative FI compared to pasta and sauce. All pulses led to lower BG peak and cumulative area under the curve (AUC; 0-340 min); however, only chickpeas, lentils and navy beans reduced pre-pizza meal BG AUC (0-260 min) relative to pasta and sauce. Chickpeas led to lower post-pizza meal BG AUC (260-340 min) compared to navy beans and yellow peas. Consumption of pulses in a high-glycaemic meal contributes to earlier satiation, lower BG following the meal and after a later meal, but these effects are specific to pulse type and cannot be explained by their glycaemic properties alone.

    Full Text Available This review paper highlights scenario of entomological research in grain legumes in Nepal into headings of the monitoring, survey and surveillance, insect pest management, existing problem and future strategies. A survey study on yield loss assessment of chickpea due to Helicoverpa pod borer under field condition has been recorded up to 75% in the year 1996-1998 at Banke and Bardiya district. While monitored Helicoverpa armigera through pheromone trap, during the 2nd week of March, peak catches of 91 male moths were recorded at Rampur, while it was the maximum (42 male moths during the 3rd week of March. Synthetic pyrethroids, deltamethrin, fenvalerate and cypermethrin used at 0.01% concentration (a.i., were effective in controlling the chickpea pod borer, Helicoverpa armigera Hubner. Genotypes NCH-18, NCH -31, NCH-138 and ICC 3075 WR were found resistant. Ripcord 10%@0.05% was found to be superior and effective chemical insecticides to control stem fly and soybean hairy caterpillar. The late sowing date December, 10 showed significantly higher percentage of chickpea pod borer damage with lower grain yield. Inter crops combinations of Chickpea +wheat (2:1 ratio was found effective against Helicoverpa armigera damage (1.2% followed by chickpea+barley (2.36% and Chickpea+linseed (2:1 ratio (3.7%. Bakaino (Melia azederach L. was identified as the best indigenous pesticides to check the normal growth of hairy caterpillar (Spilarctia casigneta kollar under laboratory condition. Metarhizium anisopliae was found effective for the management of Helicoverpa armigera that caused maximum mortality (94.67%, infection (45.33% within 7.49 days (LT50.

    Full Text Available This study evaluated and compared the effect of the utilization of five different non-conventional starches (chickpea, common bean, Peruvian carrot, sweet potato and white bean and four different commercial starches (cassava, corn, potato and rice in pound cake. Common bean starch, followed by Peruvian carrot starch were the non-conventional starch sources that showed tendency to improve the technological quality of pound cake, mainly in relation to corn starch, the most common commercial source. With these sources, the batters presented lower specific gravity and the cakes presented higher specific volume, lighter color, lower crumb moisture reduction during the storage period, and better texture attributes during all the cake shelf-life. Moreover, common bean starch provided higher scores in the cake sensory evaluation; especially for grain and texture attributes (moisture, tenderness and softness. Chickpea and white bean starches were more similar to corn starch in pound cake application.

    International Nuclear Information System (INIS)

    Food irradiation is an evolving preserving technique that provides a shield against the spoilage and might have a potential to ensure the food safety and security world wide. In the present study, feasibility to apply germination test to distinguish an un-irradiated and irradiated samples of wheat, maize, chickpea and black eye beans was checked. Samples were irradiated to the absorbed doses ranging from 0-10 kGy using Co-60 gamma irradiator and were germinated in plant growth chamber. Root and shoot lengths were measured at 7th day after gamma radiation treatment. In all the irradiated samples root and shoot lengths were decreased with the increase in radiation absorbed doses. The seeds irradiated to the absorbed doses more than 2 kGy were not germinated. Germination test proved as an easy and simple method to detect irradiation in wheat, maize, chickpea and black eye beans irradiated even at low absorbed doses. (author)

    2011-10-01

    Pulses are low-glycemic appetite-suppressing foods, but it is not known whether these properties persist after being consumed as part of a meal and after a second meal. The objective of this study was to determine the effects of a fixed-size pulse meal on appetite and blood glucose (BG) before and after an ad libitum test meal (pizza) and on food intake (FI) at the test meal. Males (n = 25; 21.3 ± 0.5 years; 21.6 ± 0.3 kg·m(-2)) randomly consumed 4 isocaloric meals: chickpea; lentil; yellow split pea; and macaroni and cheese (control). Commercially available canned pulses provided 250 kcal, and were consumed with macaroni and tomato sauce. FI was measured at a pizza meal 260 min after consumption of the isocaloric meal. BG and appetite were measured from 0 to 340 min. The lentil and yellow pea, but not chickpea, treatments led to lower appetite ratings during the 260 min prepizza meal period, and less FI at the pizza meal, compared with macaroni and cheese (p pizza meal, BG was lower following the chickpea and lentil treatments, but not the yellow pea treatment (p < 0.05). Postpizza meal BG AUC was lower following the chickpea and lentil treatments than in the yellow pea treatment (p < 0.05). The beneficial effects of consuming a pulse meal on appetite, FI at a later meal, and the BG response to a later meal are dependent on pulse type. PMID:21957874

    Science.gov (United States)

    Fan, X H; Tang, C; Rengel, Z

    2002-09-01

    Nitrate uptake, nitrate reductase activity (NRA) and net proton release were compared in five grain legumes grown at 0.2 and 2 mM nitrate in nutrient solution. Nitrate treatments, imposed on 22-d-old, fully nodulated plants, lasted for 21 d. Increasing nitrate supply did not significantly influence the growth of any of the species during the treatment, but yellow lupin (Lupinus luteus) had a higher growth rate than the other species examined. At 0.2 mM nitrate supply, nitrate uptake rates ranged from 0.6 to 1.5 mg N g(-1) d(-1) in the order: yellow lupin > field pea (Pisum sativum) > chickpea (Cicer arietinum) > narrow-leafed lupin (L angustifolius) > white lupin (L albus). At 2 mM nitrate supply, nitrate uptake ranged from 1.7 to 8.2 mg N g(-1) d(-1) in the order: field pea > chickpea > white lupin > yellow lupin > narrow-leafed lupin. Nitrate reductase activity increased with increased nitrate supply, with the majority of NRA being present in shoots. Field pea and chickpea had much higher shoot NRA than the three lupin species. When 0.2 mM nitrate was supplied, narrow-leafed lupinreleased the most H+ per unit root biomass per day, followed by yellow lupin, white lupin, field pea and chickpea. At 2 mM nitrate, narrow-leafed lupin and yellow lupin showed net proton release, whereas the other species, especially field pea, showed net OH- release. Irrespective of legume species and nitrate supply, proton release was negatively correlated with nitrate uptake and NRA in shoots, but not with NRA in roots. PMID:12234143

    International Nuclear Information System (INIS)

    Three mutant varieties, 16 hybrids of advanced generation, 6 recommended varieties and many local collections of rice in Bangladesh were screened for protein content. The 25 varieties or strains showed a variation of protein content between 8.9 - 11.7% and also wide ranges of variation in amylose content, starch-iodine-blue value and water absorption by grain. Amino acid compositions of some promising varieties were also investigated. 60 rice germplasms tested also showed a wide range of variation in protein content (6-13%) and variations of other seed characteristics. 3000 local collections showed a variation range of 5-13% protein content. Mutation breedings were carried out on chickpeas and lentils on a large scale. Dry seed was treated with 60Co gamma ray and mutants were detected, selected, particularly for high protein content, and evaluated in M2-M8 generations. Of the 10 selected mutant lines of each of the pulses, variations of various agronomic characters were observed. However, induced variation in protein content was only remarkable in chickpea. The most promising chickpea mutant showed 19% higher yield and 12% higher protein content than the mother variety, and was proposed to be released as a variety

    Full Text Available The incidence of winter and summer diapause was studied by large-scale field samplings of larvae and pupae of the cotton bollworm, Helicoverpa armigera (Hüb conducted over a period of 13-years during winter and summer seasons in Andhra Pradesh, India. Induction of winter diapause was associated with cooler prevailing temperatures and shorter day lengths of 32°C during March-April resulting in greater adult emergence with the onset of the monsoon season during mid-June to early July. In summer, few alternate hosts are available for larvae to sustain by allowing local populations colonizing newly germinated host crops with the onset of the rainy season. In addition, the incidence of winter and summer diapause was higher in male pupae than females in the ratio of 4:1 and 3:1 (♂:♀, respectively. Diapause populations of H. armigera were most common in the cyclonic weather prevailed for several weeks during 1977-78 (15.11% and 1995-96 (17.64%. Under these conditions, an average of <4% and <6% of pupae entered winter and summer diapause, respectively and was associated with severe outbreaks of H. armigera in subsequent seasons. Higher populations of H. armigera on pigeonpea and chickpea entered winter diapause on pigeonpea and chickpea and summer diapause on irrigated maize, pigeonpea, chickpea and a common weed host, Datura metel.

    Full Text Available To estimate genetic diversity within and between 10 interfertile Cicer species (94 genotypes from the primary, secondary and tertiary gene pool, we analysed 5,257 DArT markers and 651 KASPar SNP markers. Based on successful allele calling in the tertiary gene pool, 2,763 DArT and 624 SNP markers that are polymorphic between genotypes from the gene pools were analyzed further. STRUCTURE analyses were consistent with 3 cultivated populations, representing kabuli, desi and pea-shaped seed types, with substantial admixture among these groups, while two wild populations were observed using DArT markers. AMOVA was used to partition variance among hierarchical sets of landraces and wild species at both the geographical and species level, with 61% of the variation found between species, and 39% within species. Molecular variance among the wild species was high (39% compared to the variation present in cultivated material (10%. Observed heterozygosity was higher in wild species than the cultivated species for each linkage group. Our results support the Fertile Crescent both as the center of domestication and diversification of chickpea. The collection used in the present study covers all the three regions of historical chickpea cultivation, with the highest diversity in the Fertile Crescent region. Shared alleles between different gene pools suggest the possibility of gene flow among these species or incomplete lineage sorting and could indicate complicated patterns of divergence and fusion of wild chickpea taxa in the past.

    Full Text Available Total polyphenol content as well as total antioxidant capacity in three chickpea, four fababean and four lentil cultivars from regions of Iraq with different environmental growth conditions were investigated in the work. The total polyphenol content (TP was estimated using Folin-Ciocalteau assay and the total antioxidant capacity (TAC of legume extracts was measured using the DPPH spectrophotometrically. The obtained results confirmed that the polyphenols content in the tested legume cultivars was influenced by locality. From tested legumes the highest polyphenol content was measured in fababean (1220 – 6286 mg GAE.kg-1. In lentil (2351 – 3011 mgGAE.kg-1 the average TP value was slightly lower (by 1,6%, while in chickpea (549 – 978 mg GAE.kg-1 it was dramatically (by 71,5% lower in comparison to fababean. The similar trend was observed at values of TAC. The highest average TAC value was determined in fababean (15.2 – 25.6% DPPH, in lentil (14.2 – 28.9% DPPH the TAC value was by 2% and in chickpea (1.9 – 4.5% DPPH by 83,6% lower in comparison to fababean. Only in lentil a statistically strong correlation (P-value 2.391E-06; R = 0.802 was found. Our results confirmed that legumes can be a good source of bioactive compounds in the human nutrition.

    Effects of rhizosphere properties on the rhizosphere priming effect (RPE) are unknown. This study aimed to link species variation in RPE with plant traits and rhizosphere properties. Four C3 species (chickpea, Cicer arietinum; field pea, Pisum sativum; wheat, Triticum aestivum; and white lupin, Lupinus albus) differing in soil acidification and root exudation, were grown in a C4 soil. The CO2 released from soil was trapped using a newly developed NaOH-trapping system. White lupin and wheat showed greater positive RPEs, in contrast to the negative RPE produced by chickpea. The greatest RPE of white lupin was in line with its capacity to release root exudates, whereas the negative RPE of chickpea was attributed to its great ability to acidify rhizosphere soil. The enhanced RPE of field pea at maturity might result from high nitrogen deposition and release of structural root carbon components following root senescence. Root biomass and length played a minor role in the species variation in RPE. Rhizosphere acidification was shown to be an important factor affecting the magnitude and direction of RPE. Future studies on RPE modelling and mechanistic understanding of the processes that regulate RPE should consider the effect of rhizosphere pH. PMID:27101777

    Previous studies have shown that phytoremediation usually requires soil amendments, such as chelates, to mobilize low bioavailability heavy metals for better plant absorption and, consequently, for remediation efficiency. A total dry biomass of 3.39 and 0.0138 kg per plant was produced by a phytoremediator, Eucalyptus globulus, and a nitrogen fixing crop, Cicer arietinum (chickpea), respectively. The accumulation of Pb in E. globulus and chickpea reached 1170.61 and 1.33 mg per plant (700 and 324 mg kg(-1)), respectively, under an ethylene diamine tetraacetic acid (EDTA) treatment, which was a five and sixfold increase over the value in untreated experiments, respectively. EDTA enhanced the phytoremediation efficiency and increased the heavy metal concentration in the soil solution. In pot experiments, approximately 27 % of the initial Pb leached from the spiked soil after EDTA and 25 mm artificial precipitation additions into soil without plants, which was considerably larger than the value under the same conditions without EDTA application (7 %). E. globulus planted in a mixed culture had higher water use efficiency than monocultures of either species in field experiments, and E. globulus intercepted almost all of the artificial precipitation in the pot experiments. This study demonstrates that E. globulus can maximize the potential of EDTA for improving the phytoremediation efficiency and minimizing its negative effects to the environment simultaneously by absorbing the metal-rich leachate, especially in a mixed culture of E. globulus and chickpeas.

    2007-01-01

    Full Text Available The goal of this work was to examine interpopulation patterns in the reproductive behavior of populations of bean weevil (Acanthoscelides obtectus Say; Coleoptera: Bruchidae that had different levels of specialization on their native host plant – the bean (Phaseolus vulgaris L., as well as on a novel host plant – the chickpea (Cicer arietinum Thorn. The obtained pattern of interpopulation mating behavior seemed exactly as if the males on chickpea had evolved a specific odor and/or a courtship ritual that females of populationson bean found repulsive. Unlike females, the males of bean populations seemed to be willing to mate with females from the population on chickpea equally as with their own females. Such an asymmetric pattern of reproductive isolation between populations ofa species has been often considered an initial phase of a process of speciation. Thus, our results could be a good starting point for further, thorough examination of both the role of the level of host specialization in females and the role of biochemical characteristics of male pheromone (and/or their cuticular hydrocarbones in the evolution of pre-reproductive isolation between insect populations.As the results of this study, together those of previous studies on A. obtectus, suggest great evolutionary potential for invasions of and fast specialization on novel host plants, they could provide valuable information for the development of long-term strategiesunder the programmes of Integrated Pest Management.

  8. A chemical composition for use in radiography based on 99mTc labelling of proteinaceous material

    International Nuclear Information System (INIS)

    Chemical compositions for radioactive technetium-99m labelling of proteinaceous material include benzoic acid derivative or a water soluble salt thereof, selected from the group of aminobenzoic, monohydroxy- and dihydroxy-benzoic acid or salt thereof and a stannous salt. The composition may be in the form of a ready-to-use composition of benzoic acid derivative and stannous salt with proteins to be labelled. Ready-to-use compositions with proteins can be prepared in dry form for instant preparation by combination with a radioactive pertechnetate solution. The labelling process is advantageously performed by reduction of pertechnetate by means of divalent tin in a benzoic acid derivative containing solution of the stannous salt. The pH and ionic strenght of the solution depends on the proteins or cells which are to be labelled. The compositions are suitable for detection or scintigraphic depiction of processes in human beings or other biological organisms

  9. Factors involved in planning radiation-sterilization practices and technology in the developing countries, and the Agency's promotional role

    International Nuclear Information System (INIS)

    The application of ionizing radiation for sterilizing ready-to-use medical supplies, sutures and grafts provides a broad scope for the up-grading of public health care and family planning programmes in the developing countries. Sterile ready-to-use medical supplies become particularly important for improving the standard of those services given through the improvised camp-hospitals and mobile medical units for the remote areas of such countries, if needed. The practices generated in the technologically advanced countries will form the basis of the planning, but the necessary adjustments should be made in their implementation to suit best the local conditions and needs and to promote utilization of local raw materials. Necessary research and development and an effective infrastructure should be emphasized. Plastic materials are among the major pollutants of the environment. Timely parallel practical steps need be adopted and an action programme planned to preserve the quality of the human environment. (author)

    Breast cancers are routinely assessed for estrogen receptor status using immunohistochemical assays to assist in patient prognosis and clinical management. Specific assays vary between laboratories, and several antibodies have been validated and recommended for clinical use. As numerous factors can influence assay performance, many laboratories have opted for ready-to-use assays using automated stainers to improve reproducibility and consistency. Three commonly used autostainer vendors-Dako, Leica, and Ventana-all offer such estrogen receptor assays; however, they have never been directly compared. Here, we present a systematic comparison of three platform-specific estrogen receptor ready-to-use assays using a retrospective, tamoxifen-treated, breast cancer cohort from patients who were treated in Calgary, Alberta, Canada from 1985 to 2000. We found all assays showed good intra-observer agreement. Inter-observer pathological scoring showed some variability: Ventana had the strongest agreement followed closely by Dako, whereas Leica only showed substantial agreement. We also analyzed each estrogen receptor assay with respect to 5-year disease-free survival, and found that all performed similarly in univariate and multivariate models. Determination of measures of test performance found that the Leica assay had a lower negative predictive value than Dako or Ventana, compared with the original ligand-binding assay, while other measures-sensitivity, specificity, positive predictive value, and accuracy-were comparable between the three ready-to-use assays. When comparing against disease-free survival, the difference in negative predictive value between the vendor assays were not as extreme, but Dako and Ventana still performed slightly better than Leica. Despite some discordance, we found that all ready-to-use assays were comparable with or superior to the ligand-binding assay, endorsing their continued use. Our analysis also allowed for exploration of estrogen receptor
