    Prunus avium L. (diploid, AA, 2n=2x=16), Prunus cerasus L. (allotetraploid, AAFF, 2n=4x=32) species, and their hybrid Prunus x gondouinii Rehd., constitute the most widely cultivated cherry tree species. P. cerasus is supposed to be an hybrid species produced by the union of unreduced P. avium gametes and normal P. fruticosa gametes. A continuum of morphological traits between these three species makes their assignation difficult. The aim of this paper is to study the genetic relationships between tetraploid and diploid cherry species. In all, 114 genotypes belonging to these species were analyzed using 75 AFLP markers. The coordinates of these genotypes on the first axis of a correspondence analysis allowed us to clearly distinguish each species, to identify misclassifications and to assign unknown genotypes to one species. We showed that there are specific alleles in P. cerasus, which are not present in the A genome of P. avium and which probably come from the F genome of P. cerasus. The frequencies of each marker in the A and the F genomes were estimated in order to identify A and F specific markers. We discuss the utility of these specific markers for finding the origin of the A and F genomes in the allopolyploid species. PMID:15354194

    The isoflavone genistein on the contrary to its well-established health-beneficial effects is not a major component of the Western diet, since soy consumption, considered as the main dietary source of genistein, in these populations is low. Genistein compounds in twelve commercial sour cherry (Prunus cerasus L.) cultivars grown in Hungary were studied. High performance liquid chromatography coupled to electrospray ionisation quadrupole/time-of-flight mass spectrometry (HPLC-ESI-qToF-MS) was used for screening and confirmatory analyses. Genistin and genistein were found in 'Pipacs1', 'Kántorjánosi', 'Debreceni bőtermő' and 'Éva', which are native cultivars to Hungary. Genistein content of the latter three were in the range of 0.4-0.6, while in 'Pipacs1' in total 4.4 mg genistein compounds were measured expressed as aglycone equivalents per 100g of fresh fruit flesh. These cultivars may play important role as complementary genistein sources in the Western diet. Especially 'Pipacs 1', may be best utilised in functional food products. PMID:25053048

  11. Genetic and molecular characterization of three novel S-haplotypes in sour cherry (Prunus cerasus L.).

    Tetraploid sour cherry (Prunus cerasus L.) exhibits gametophytic self-incompatibility (GSI) whereby the specificity of self-pollen rejection is controlled by alleles of the stylar and pollen specificity genes, S-RNase and SFB (S haplotype-specific F-box protein gene), respectively. As sour cherry selections can be either self-compatible (SC) or self-incompatible (SI), polyploidy per se does not result in SC. Instead the genotype-dependent loss of SI in sour cherry is due to the accumulation of non-functional S-haplotypes. The presence of two or more non-functional S-haplotypes within sour cherry 2x pollen renders that pollen SC. Two new S-haplotypes from sour cherry, S(33) and S(34), that are presumed to be contributed by the P. fruticosa species parent, the complete S-RNase and SFB sequences of a third S-haplotype, S(35), plus the presence of two previously identified sweet cherry S-haplotypes, S(14) and S(16) are described here. Genetic segregation data demonstrated that the S(16)-, S(33)-, S(34)-, and S(35)-haplotypes present in sour cherry are fully functional. This result is consistent with our previous finding that 'hetero-allelic' pollen is incompatible in sour cherry. Phylogenetic analyses of the SFB and S-RNase sequences from available Prunus species reveal that the relationships among S-haplotypes show no correspondence to known organismal relationships at any taxonomic level within Prunus, indicating that polymorphisms at the S-locus have been maintained throughout the evolution of the genus. Furthermore, the phylogenetic relationships among SFB sequences are generally incongruent with those among S-RNase sequences for the same S-haplotypes. Hypotheses compatible with these results are discussed. PMID:18617504

    Numerous cultivars of Japanese flowering cherry (Prunus subgenus Cerasus) are recognized, but in many cases they are difficult to distinguish morphologically. Therefore, we evaluated the clonal status of 215 designated cultivars using 17 SSR markers. More than half the cultivars were morphologically distinct and had unique genotypes. However, 22 cultivars were found to consist of multiple clones, which probably originate from the chance seedlings, suggesting that their unique characteristics have not been maintained through propagation by grafting alone. We also identified 23 groups consisting of two or more cultivars with identical genotypes. Most members of these groups were putatively synonymously related and morphologically identical. However, some of them were probably derived from bud sport mutants and had distinct morphologies. SSR marker analysis provided useful insights into the clonal status of the examined Japanese flowering cherry cultivars and proved to be a useful tool for cultivar characterization. PMID:23226085

    The polysaccharide composition of cell wall of sour cherry (Prunus cerasus var. Schattenmorelle) fruit and pomace was investigated. Furthermore, the alcohol insoluble solids composition of 'Kelleriis' and 'Dobreczyn Botermo' varieties were studied too. Yield of alcohol insoluble solids for fruits was lower than 10%, and for pomaces circa 50%. Uronic acid was the main pectin component of alcohol insoluble solids. Enzymes used as juice processing aids decreased the content of uronic acid. Araban and galactan side chains bonded tightly to cellulose presence was suggested by high content of arabinose and galactose in hemicellulose fraction. The process of drying at below 70 degrees C did not influence polysaccharide composition of sour cherry pomaces. Alcohol insoluble solids of fruits expressed higher hydration properties than of pomaces. PMID:19757068

    The present investigation tested the in vivo antioxidant efficacy (superoxide dismutase, SOD; catalase, CAT; glutathione peroxidase; Gpx), lipid peroxidation (LPO) and anti-inflammatory properties (cyclooxygenase-2; COX-2) of sour cherry juices obtained from an autochthonous cultivar (Prunus cerasus cv. Maraska) that is grown in coastal parts of Croatia. Antioxidant potential was tested in mouse tissue (blood, liver, and brain), LPO (liver, brain) and anti-inflammatory properties in glycogen elicited macrophages. Additionally, the concentration of cyanidin-3-glucoside, cyanidin-3-rutinoside, pelargonidin-3-glucoside, pelargonidin-3-rutinoside and total anthocyanins present in Prunus cerasus cv. Maraska cherry juice was determined. Mice were randomly divided into a control group (fed with commercial food pellets) and 2 experimental groups (fed with commercial food pellets with 10% or 50% of cherry juice added). Among the anthocyanins, the cyanidin-3-glucoside was present in the highest concentration. These results show antioxidant action of cherry juice through increased SOD (liver, blood) and Gpx (liver) activity and decreased LPO concentration. The study highlights cherry juice as a potent COX-2 inhibitor and antioxidant in the liver and blood of mice, but not in the brain. Thus, according to our study, Prunus cerasus cv. Maraska cherry juice might potentially be used as an antioxidant and anti-inflammatory product with beneficial health-promoting properties. PMID:19763832

    Tetraploid sour cherry (Prunus cerasus) exhibits a genotype-dependent loss of gametophytic self-incompatibility that is caused by the accumulation of non-functional S-haplotypes with disrupted pistil component (stylar-S) and/or pollen component (pollen-S) function. Genetic studies using diverse sour cherry germplasm identified non-functional S-haplotypes for which an equivalent wild-type S-haplotype was present in sweet cherry (Prunus avium), a diploid progenitor of sour cherry. In all cases, the non-functional S-haplotype resulted from mutations affecting the stylar component S-RNase or Prunus pollen component S-haplotype-specific F-box protein (SFB). This study determines the molecular bases of three of these S-haplotypes that confer unilateral incompatibility, two stylar-part mutants (S(6m2) and S(13m)) and one pollen-part mutant (S(13)'). Compared to their wild-type alleles, S(6m2)-RNase has a 1 bp deletion, S(13m) -RNase has a 23 bp deletion and SFB(13)' has a 1 bp substitution that lead to premature stop codons. Transcripts were identified for these three alleles, S(6m2)-RNase, S(13m)-RNase, and SFB(13)', however, these transcripts presumably result in altered proteins with a resulting loss of activity. Our characterization of natural pollen-part and stylar-part mutants in sour cherry along with other natural S-haplotype mutants identified in Prunus supports the view that loss of pollen specificity and stylar rejection evolve independently and are caused by structural alterations affecting the S-haplotype. The prevalence of non-functional S-haplotypes in sour cherry but not in sweet cherry (a diploid) suggests that polyploidization and gene duplication were indirectly responsible for the dysfunction of some S-haplotypes and the emergence of self-compatibility in sour cherry. This resembles the specific mode of evolution in yeast where accelerated evolution occurred to one member of the duplicated gene pair. PMID:16915517

The evaluation and characterization of the in vitro produced pigments are compared to those of the anthocyanins found in vivo in fruits of several sour cherry cultivars. Interestingly, the anthocyanin profiles found in whole fruit extracts were similar in all tested genotypes but were different with respect to the callus extract. The evaluation of antioxidant activity, performed by ORAC and TEAC assays, revealed a relatively high antioxidant capacity for the fruit extracts (from 1145 to 2592 $\\mu $ mol TE/100 g FW) and a lower one for the callus extract (688 $\\mu $ mol TE/100 g FW).

    A plant-based diet reduces the risk for the development of several chronic diseases, such as ischemic heart disease or cancer due to natural compounds found in plants. Numerous cereals, berries, fruits, and vegetables, including sour cherry (Prunus cerasus), which is a favored fruit worldwide, contain biological active components. The antioxidant components of the sour cherry seed kernel have not been investigated until now. The aim of our study was to isolate and analyze the bioactive constituents of sour cherry seed kernel. We separated the oil fraction of the kernel; then the remaining solid fraction was dried, and the oil-free kernel extract was further analyzed. Our results show that sour cherry seed kernel oil contains vegetable oils including unsaturated fatty acids, oleic acids, alpha-tocopherol, tocotrienols, and tocopherol-like components. The components of the solid fraction include various bioactive structures such as polyphenols, flavonoids, vegetable acids, and pro- and anthocyanidins, which could have useful therapeutic effects in the prevention of various vascular diseases.

    The effects of kernel extract obtained from sour cherry (Prunus cerasus) seed on the postischemic cardiac recovery were studied in isolated working rat hearts. Rats were treated with various daily doses of the extract for 14 days, and hearts were then isolated and subjected to 30 min of global ischemia followed by 120 min of reperfusion. The incidence of ventricular fibrillation (VF) and tachycardia (VT) fell from their control values of 92% and 100% to 50% (not significant) and 58% (not significant), 17% (P<0.05), and 25% (P<0.05) with the doses of 10 mg/kg and 30 mg/kg of the extract, respectively. Lower concentrations of the extract (1 and 5 mg/kg) failed to significantly reduce the incidence of VF and VT during reperfusion. Sour cherry seed kernel extract (10 and 30 mg/kg) significantly improved the postischemic recovery of cardiac function (coronary flow, aortic flow, and left ventricular developed pressure) during reperfusion. We have also demonstrated that the extract-induced protection in cardiac function significantly reflected in a reduction of infarct size. Immunohistochemistry indicates that a reduction in caspase-3 activity and apoptotic cells by the extract, beside other potential action mechanisms of proanthocyanidin, trans-resveratrol, and flavonoid components of the extract, could be responsible for the cardioprotection in ischemic-reperfused myocardium.

    Full Text Available Low fruit set, despite normally-developed flowers, is often a significant contributor to poor yield of the self-fertile sour cherry (Prunus cerasus cultivar ‘Stevnsbaer’ in Denmark. The aim of this study was to investigate the effect of insect, and particularly, bee pollination on the fruit set of this cultivar, in order to provide orchard management information for both Danish ‘Stevnsbaer’ growers and beekeepers. Visits to cherry flowers by honey bees (Apis mellifera, Bombus species and solitary bees, were recorded during the flowering of ‘Stevnsbaer’ in five separate Danish orchards. The results indicate that there is a significantly higher fruit set on open pollinated branches when compared to caged branches, where bees and other pollinating insects where excluded. The results were qualitatively consistent over three different seasons (2007, 2009 and 2010. A period of prolonged cold, humid weather before and during early flowering probably reduced fruit set significantly in 2010 compared to 2009. Regarding the apparent benefits of bee pollination on fruit set and subsequent implications for yield, we recommend placing honeybees in ‘Stevnsbaer’ orchards during flowering to sustain commercially viable production. Another valuable management strategy would be to improve foraging and nesting conditions to support both honey and wild bees in and around the orchards.

    Full Text Available At Fruit Research Institute in Čačak, major objectives of the work on breeding new sour cherry (Prunus cerasus L. cultivars are high cropping, large, high-quality fruits and resistance to causal agents of diseases and pests. As a result of the planned hybridization, more than 10,000 hybrid seedlings have been developed from about 40 cultivars within more than 110 parental combinations, among which are 'Čačanski rubin' ('Shasse Morello' x 'Köröser Weichsel' and 'Šumadinka' ('Köröser Weichsel' x 'Heimanns Konserven Weichsel' which have been named and released. Ten-year study of 11 hybrids, selected from the population of about 3,000 hybrid seedlings, gave four hybrids which have been singled out as elite (III/23, III/31, II/40 i XII/57. These hybrids are currently under procedure of being released as new cultivars. The paper presents two-year results of the study of ripening time, pomological properties, biochemical composition of fruits, and field resistance to causal agents of diseases and pests attacking the above named genotypes which were compared to standard cultivar 'Heimanns Konserven Weichsel'. In the studied hybrids, fruit weight, soluble solids content and sugars content were higher than in standard cultivar. In addition, they exhibit substantial field resistance to causal agents of brown rot (Monilinia laxa /Ader et Ruhl./ Honey ex Whetz., cherry leaf spot (Blumeriella jaapii (Rehm. v.

    Many edible plant metabolites are known to be useful as cellular antioxidants. In the search for antioxidative chemicals from native fruits of the Campania region of Italy, Prunus cerasus L., an acidic cherry widely used for culinary purposes, has been studied. Fruit crude extracts (MeOH, EtOAc, and hexane) were submitted to an antioxidative screening using specific assay media characterized from the presence of highly reactive radical species (DPPH*, ABTS*+, O2*-, NO) or lipoperoxidation markers. The reducing power of the samples was also determined. It was observed that the most polar extracts in MeOH and EtOAc were able to exercise a massive and dose-increasing antioxidative capacity. The peculiar efficacy of the same extracts was revealed by investigating their protein and deoxyribose oxidation capacity. A preliminary analysis of total phenol, flavonoid, and anthocyanin contents together with biological screening data put the basis on P. cerasus fruit phytochemical investigation of methanolic extract. Twenty secondary metabolites were isolated and characterized by spectroscopic (especially 1D and 2D NMR) and spectrometric techniques. 1-(4-Hydroxyphenyl)-1,2-ethanediol-1,2-bis-1-O-beta-D-glucopyranoside (3), (4-hydroxy-3-methoxyphenyl)methanol-1-O-beta-D-gentiobioside (4), epicatechin-3-malate (14), and epicatechin-3-(1''-methyl)malate (15) were isolated for the first time. All of the compounds were evaluated for their radical scavenging activity on DPPH*, O2*-, and NO. Flavonoids and quinic acid derivatives were found to be the more antioxidative substances.

    The sour cherry (Prunus cerasus) cv. Stevnsbaer is self-fertile but it is recommended that bees are placed in the orchards during flowering. The solitary bee Osmia rufa can be managed, and has previously been suggested as an alternative pollinator to Apis mellifera, so consequently, this study....... The remaining 8 pollen types were from entomophilous plants. Based on the results it is estimated that a mean of 220,000 O. rufa cocoons would be needed per hectare if the species were to be an effective, supplementary pollinator of P. cerasus cv. Stevnsbaer. Practical, economic and environmental considerations...... suggest that the use of O. rufa as an alternative pollinator to A. mellifera in this instance is not realistic....

    The glycoside hydrolase activity of Saccharomyces cerevisiae and Brettanomyces custersii was examined on sour cherry (Prunus cerasus L.) glycosides with bound volatile compounds. Refermentations by the beta-glucosidase-negative S. cerevisiae strains LD25 and LD40 of sour cherry juice-supplemented beer demonstrated only a moderate increase of volatiles. In contrast, the beta-glucosidase-positive B. custersii strain LD72 showed a more pronounced activity towards glycosides with aliphatic alcohols, aromatic compounds and terpenoid alcohols. Important contributors to sour cherry aroma such as benzaldehyde, linalool and eugenol were released during refermentation as shown by analytical tools. A gradually increasing release was observed during refermentations by B. custersii when whole sour cherries, sour cherry pulp or juice were supplemented in the beer. Refermentations with whole sour cherries and with sour cherry stones demonstrated an increased formation of benzyl compounds. Thus, amygdalin was partially hydrolysed, and a large part of the benzaldehyde formed was mainly reduced to benzyl alcohol and some further esterified to benzyl acetate. These findings demonstrate the importance and interesting role of certain Brettanomyces species in the production of fruit lambic beers such as 'Kriek'. PMID:18673394

    The present study, investigates the effects of melatonin (0, 0.05, 0.1, 0.5, 1, 5 and 10 μM) on the morphogenic and biochemical responses in the cherry rootstock PHL-C (Prunus avium L. × Prunus cerasus L.), from shoot tip explants. The incorporation of melatonin (0-10 μM) in the Murashige and Skoog (MS) medium, greatly influenced rooting either positively or negatively. Melatonin, irrespective of its concentration, had a negative effect concerning the number of roots. However, application of 0.5 μM melatonin significantly increased the root length; while 1 μM melatonin increased the root length by 2.5 times, and the fresh weight of the roots by 4 times, in comparison to the control. Although 0.05 μM melatonin increased rooting by 11.11%, 5 μM melatonin had a significant reduction on the number, the fresh weight of roots, and the rooting percentage. Melatonin concentration of 0.1 μM resulted in the greatest chlorophyll (a + b) content, and 5-10 μM reduced the chlorophyll concentration by 2 times, compared to the control. The high melatonin concentrations (5 and 10 μM), increased the levels of proline and carbohydrates in leaves by 3-4 times. In the roots, 0.5 μM of melatonin concentration increased the carbohydrate levels by 1.5 times, while 0.05, 0.1 and 1 μM melatonin concentration significantly reduced the proline content.

    This study describes a novel F-box protein gene in the S-locus of sour cherry (Prunus cerasus) and sweet cherry (P. avium). The gene showed an S-haplotype-specific sequence polymorphism and the expression was specific to pollen. Genomic DNA blot analysis of eight sweet cherry cultivars with the probe for the F-box protein gene under low stringency conditions yielded RFLP bands specific to the S-haplotypes of each cultivar. We discuss the possibility of the gene for the F-box protein being a candidate for the male determinant of gametophytic self-incompatibility in PRUNUS: PMID:12881505

    Full Text Available Extracts from young leaves of nine sweet cherry (Prunus avium L. and eight sour cherry (Prunus cerasus L. varieties, located in the germplasm collection of the 'Direção Regional de Agricultura da Beira Interior' (Fundão, Portugal, were analysed for five isozyme systems in order to characterise these varieties and detect problems of synonymies and homonymies that frequently present. The sweet and sour cherry varieties analyzed showed low isoenzymatic polymorphism, being PGM and PGI the systems with the highest discrimination power. These systems presented seven and five different zymogrames, respectively. IDH showed four patterns. SKDH and 6-PGD grouped the varieties only into two patterns. The evident and discriminant restrictions of this type of analysis had got results that have only been a complement for agronomical and morphological characterization.Nove extratos de folhas com desenvolvimento encompleto foram obtidos de 9 variedades de cerejeira (Prunus avium L. e 8 de ginjeira (Prunus cerasus L., localizados no campo de germoplasma da "Direcção Regional de Agricultura da Beira Interior" (Fundão, Portugal. Esses extratos foram analisados para 5 sistemas isoenzimáticos a fim de caracterizar essas variedades e simultaneamente detectar sinonímias e homonímias, freqüentes neste tipo de estudos. As variedades de cerejeira e ginjeira analisadas mostraram baixo polimorfismo isoenzimático, sendo que os sistemas PGM e PGI mostraram maior poder de discriminação. Estes sistemas apresentaram 7 e 5 zimogramas diferentes, respectivamente. IDH mostrou 4 padrões. SKDH e 6-PGD agruparam as variedades em 2 padrões. Os evidentes limites discriminatórios desse tipo de análise serviram somente de complemento para a caracterização agronômica e morfológica.

    Anthocyanins can contribute to human health through preventing a variety of diseases. The uptake of these compounds from food and the parameters determining uptake efficiency within the human body are still poorly understood. Here we have employed a Caco-2 cell based system to investigate the transport of key antioxidant food components from sour cherry (Prunus cerasus L.) across the intestinal epithelial barrier. Anthocyanins and (-)-epicatechin were supplied in three contrasting matrices: fruit, processed fruit cherry juice, and polyphenolic fractions obtained by solid-phase extraction. Results show that both compound types behave differently. Fruit or juice matrices display comparable transport across the epithelial cell layer. The juice supplements sucrose and citric acid, which are regularly added to processed foods, have a positive effect on stability and transport. Polyphenolic fractions display a lower transport efficiency, relative to that of the fruit or juice, indicating the importance of food matrix components for intestinal absorption of polyphenols.

    Full Text Available Color is very important indicator of quality of fresh fruit. It also serves for estimating the stage of maturity of fruit. Plant pigments responsible for the color of some kind of fruits are anthocyanins. Anthocyanins are the flavonoids which are present in high amounts in sour cherries. The aim of this study was to determine total anthocyanins and color parameters of sour cherries ‘Cigančica’ and ‘Keleris’ collected in Osijek and Zadar (Croatia in 2005 during ripening. Color parameters of skin and fl esh of sour cherries were determined with colorimetric CIE LAB method and total anthocyanins were determined by means of high performance liquid chromatography (HPLC using UV/VIS PDA detector. Total anthocyanin was higher in sour cherries cv. Keleris grown in Zadar than in cv. Cigančica grown in Osijek during ripening although cv. Keleris is light colored genotype. Obtained results suggested that warm Mediterranean climate could have influence on high anthocyanin synthesis during ripening. Analysis of variance showed that stage of ripening did not influence total anthocyanin concentrations, but influenced almost all color parameters. Parameter H° was good indicator of color variation during ripening in both sour cherry cultivars.

    The antioxidant capacities, total polyphenolic content and monomeric anthocyanin content of eleven types of sour cherry juice obtained from different varieties of sour cherries were investigated. Antioxidant capacity, total polyphenolic content and monomeric anthocyanin contents of the juices were within the ranges 20.0-37.9 mmol/L, 1510-2550 and 350.0-633.5mg/L, respectively. The main anthocyanin compound in sour cherry juice was cyanidin-3-glucosylrutinoside at concentrations between 140.3 and 320.9 mg/L. Cyanidin-3-glucosylrutinoside was followed by cyanidin-3-rutinoside within a concentration range of 25.5-85.5mg/L. Cyanidin-3-sophoroside and cyanidin-3-glucoside contents were relatively low (2.6-21.5 and 2.0-9.9 mg/L). Anthocyanin capacity and total polyphenol content were fairly well correlated (r=0.742, p0.05). The correlation between antioxidant capacity - cya-3-glucosylrutinoside (r=0.606, p<0.01) and antioxidant capacity - cya-3-rutinoside (r=0.628, p<0.01) was significant. PMID:22980889

    Full Text Available Sour cherry is an important fruit in Croatian orchards. Cultivar Oblačinska is predominant in existing orchards with noted intracultivar phenotypic heterogeneity. In this study, the genetic variability of 22 genotypes of cvs. Oblačinska, Maraska and Cigančica, as well as standard cvs. Kelleris 14, Kelleris 16, Kereška, Rexelle and Heimann conserved were investigated. Two types of molecular markers were used: microsatellite markers (SSR in order to identify intercultivar, and AFLP in order to identify intracultivar variabilities. A set of 12 SSR markers revealed small genetic distance between cvs. Maraska and Oblačinska while cv. Cigančica is affined to cv. Oblačinska. Furthermore, cvs. Oblačinska, Cigančica and Maraska were characterized compared to standard ones. AFLP markers didn`t confirm significant intracultivar variability of cv. Oblačinska although the variability has been approved at the morphological, chemical and pomological level. Significant corelation between SSR and AFLP markers was found. Identification of sour cherry cultivars tolerant to drought will enable the sustainability of fruit production with respect to the climate change in the future. For this purpose, the tolerance of seven sour cherry genotypes (cvs. Kelleris 16, Maraska, Cigančica and Oblačinska represented by 4 genotypes: OS, 18, D6 and BOR to drought conditions was tested in order to isolate genotypes with the desired properties. In the greenhouse experiment, cherry plants were exposed to drought stress. The leaf relative water content, OJIP test parameters which specify efficiency of the photosynthetic system based on measurements of chlorophyll a fluorescence, and concentrations of photo-synthetic pigments during the experiment were measured as markers of drought tolerance. Photosynthetic performance index (PIABS comprises three key events in the reaction centre of photosystem II affecting the photosynthetic activity: the absorption of energy

    Full Text Available Dehydrogenase polymorphism was studied in 36 sour cherry (Prunus cerasus L., sweet cherry (Prunus avuim L., mahaleb (Prunus mahaleb L., ground cherry (Prunus fruticosa Pall., duke cherry (Prunus gondounii Redh., Japanese flowering cherry (Prunus serrulata Lindl. and four iterspecific hybrids (standard cherry rootstocks ‘Gisela 5’, ‘Gisela 6’, ‘Max Ma’ and ‘Colt’. Inner bark of one-year-old shoots, in dormant stage, was used for enzyme extraction. Vertical PAGE was used for isoenzyme analysis: alcohol dehydrogenase (ADH, formate dehydrogenase (FDH, glutamate dehydrogenase (GDH, isocitrate dehydrogenaze (IDH, malate dehydrogenase (MDH, phosphogluconate dehydrogenase (PGD, and shikimate dehydrogenase (SDH. All studied systems were polymorphic at 10 loci: Adh -1 (3 genotypes and Adh-2 (5 genotypes, Fdh-1 (2 genotypes, Gdh-1 (3 genotypes, Idh-1 (4 genotypes i Idh -2 (5 genotypes, Mdh-1 (3 genotypes, Pgd-1 (4 genotypes, Sdh-1 (1 genotype i Sdh-2 (3 genotypes. Cluster analysis was used to construct dendrogram on which four groups of similar genotypes were separated. Obtained results indicate that studied enzyme systems can be used for determination of genus Prunus, subgenus Cerasus. Among studied enzyme systems ADH, IDH and SDH were the most polymorphic and most useful to identify genetic variability. Polymorphism of FDH and GDH in genus Prunus, subgenus Cerasus was described first time in this work. First results for dehydrogenase variability of Oblačinska indicate that polymorphism of loci Idh-2 and Sdh-2 can be useful for discrimination of different clones.

    Full Text Available Based on examination of 10 important pomologic and technologic properties, genetic divergence of 10 selected Oblačinska sour cherry clones was established. The genetic divergence between the analyzed clones was determined using the hierarchical cluster analysis. The UPGA method was used and the Euclidean distance in order to determine the difference between the groups. Four similar clone groups were obtained on the dendrogram. The objective of clone differentiation was primarily yield, although other properties were taken into account as well. As the most yielded clones for the production, that can be recommended, were clone D8 or clone D4 that are genetically very similar, and clone D3.

    The aim of this study was to evaluate the influence of packaging materials and storage conditions on polyphenols stability, colour and sensory characteristics of freeze-dried sour cherry (Prunus cerasus var. Marasca). Freeze-dried sour cherries were packed in high barrier metalized polypropylene and aluminium packaging (PET/PPmet/PE and PET/Al/PE) for up to 12 months at 4, 20 and 37 °C. Characterisation of polyphenol compounds was done by HPLC UV/Vis PDA and in all samples individual anthocyanins (ANTs), flavonol-glycosides (FGs) and hydroxycinnamic acids (HCAs) were determined. Polyphenol content was not markedly affected by freeze-drying and decreases were amounted 1.5-5 %. Furthermore, obtained results indicated that minimal loss of polyphenol content in freeze dried sour cherries were achieved at 4 °C and 3 months of storage. Regardless of the type of packaging materials, samples stored at lower temperature during 12 months, retained the higher content of FGs (quercetin-3-glucoside, kaempferol-3-glucoside, kaempferol-3-rutinoside) and HCAs (neochlorogenic, chlorogenic, p-coumaric, caffeic and ferulic acid) than ANTs (cyanidin-3-glucosylrutinoside, cyanidin-3-rutinoside, cyanidin-3-glucoside, cyanidin-3-sophoroside). The same trend was confirmed with kinetic parameters, also. Sour cherry products packed in both type of laminate and stored at lower temperature retained characteristic dark red colour and sensory properties. This study showed that freeze-dried cherry products have pleasant sensory and very good nutritional properties, and storage in both type of laminates at 4 and 20 °C up to 6 months ensured good product quality.

    Tetraploid sour cherry (Prunus cerasus) has an S-RNase-based gametophytic self-incompatibility (GSI) system; however, individuals can be either self-incompatible (SI) or self-compatible (SC). Unlike the situation in the Solanaceae, where self-compatibility accompanying polyploidization is often due to the compatibility of heteroallelic pollen, the genotype-dependent loss of SI in sour cherry is due to the compatibility of pollen containing two nonfunctional S haplotypes. Sour cherry individuals with the S(4)S(6)S(36a)S(36b) genotype are predicted to be SC, as only pollen containing both nonfunctional S(36a) and S(36b) haplotypes would be SC. However, we previously found that individuals of this genotype were SI. Here we describe four nonfunctional S(36) variants. Our molecular analyses identified a mutation that would confer loss of stylar S function for one of the variants, and two alterations that might cause loss of pollen S function for all four variants. Genetic crosses showed that individuals possessing two nonfunctional S(36) haplotypes and two functional S haplotypes have reduced self-fertilization due to a very low frequency of transmission of the one pollen type that would be SC. Our finding that the underlying mechanism limiting successful transmission of genetically compatible gametes does not involve GSI is consistent with our previous genetic model for Prunus in which heteroallelic pollen is incompatible. This provides a unique case in which breakdown of SI does not occur despite the potential to generate SC pollen genotypes. PMID:19917768

    The objectives of this study were to test the effects of melatonin (N-acetyl-5-methoxytryptamine), a natural compound of edible plants on the rooting of certain commercial sweet cherry rootstocks. Shoot tip explants from previous in vitro cultures of the cherry rootstocks CAB-6P (Prunus cerasus L.), Gisela 6 (P. cerasus × P. canescens), and M × M 60 (P. avium × P. mahaleb) were included in the experiment. The effect of indole-3-acetic acid (IAA) and indole-3-butyric acid (IBA) alone or in combination with melatonin was tested concerning their rooting potential. Seven concentrations of melatonin (0, 0.05, 0.1, 0.5, 1, 5, and 10 μM) alone or in combination with 5.71 μM of IAA or 4.92 μM of IBA were tested. For each rootstock, 21 treatments were included. The explants were grown in glass tubes containing 10 mL of substrate. The parameters measured include rooting percentage, number of roots per rooted explant, root length, and callus formation. The data presented in this study show that melatonin has a rooting promoting effect at a low concentration but a growth inhibitory effect at high concentrations. In the absence of auxin, 1 μM melatonin had auxinic response concerning the number and length of roots, but 10 μM melatonin was inhibitory to rooting in all the tested rootstocks. The final conclusion of this experiment is that exogenously applied melatonin acted as a rooting promoter and its action was similar to that of IAA. PMID:21749439

    Retrospectively, we have measured the antioxidant activity and a variety of antioxidant compounds under versatile extraction conditions of sweet cherry (Prunus avium) extracts. Further in this study, in order to understand the biochemical constituents and antioxidant activities of a variety of extracts of black sour cherries (P. cerasus), a related species, antioxidant compounds, including L-ascorbic acid (vitamin C), phenols, flavonoids, and anthocyanins, and the total antioxidant activity were simultaneously measured under varying extraction conditions (mild heating and brief microwave exposure) for: i) whole juice extracts (WJE), ii) methanol-extracted juice (MEJ), iii) ddH2O-extracted pomace (dPOM), and iv) methanol-extracted pomace (mPOM). The antioxidant activity for WJE was substantially increased with mild and prolonged exposure to either heating or microwave, such that the % inhibition against 2,2-diphenyl-1-bspicrylhydrazyl (DPPH) followed a positive correlation (heating, 5-20 min.; microwave, 1-2 min.), insignificant with MEJ and dPOM, whereas with mPOM there was sharp downregulation. L-Ascorbic acid content was not affected with mild to prolonged heating or microwave exposure (WEJ and mPOM), except a mild increase with MEJ and dPOM. Similarly, total phenols assessed showed no significant variations, as compared with control extracts, except a mild decrease with exposure for mPOM. In a manner similar to L-ascorbic acid, total flavonoid content was increased under varying conditions for WEJ and MEJ, and slightly decreased for dPOM and mPOM. On the other hand, anthocyanins showed differential variations with exposure (up- and downregulation). Assessment of extraction means as compared with WJE revealed sharp increase in the antioxidant activity for MEJ, dPOM and mPOM, significant increase in L-ascorbic acid, total phenol, and flavonoid contents for MEJ, dPOM and mPOM, and mild decrease in anthocyanin contents for MEJ, dPOM, and mPOM.

    The processing of fruits, such as cherries, is characterized by generating a lot of waste material such as fruit stones, skins, etc. To contribute to environmental sustainability, it is necessary to recover these residues. Cherry stones contain seeds with a significant amount of proteins that are underused and undervalued. The aim of this work was to extract cherry seed proteins, to evaluate the presence of bioactive peptides, and to identify them by mass spectrometry. The digestion of cherry seed proteins was optimized, and three different enzymes were employed: Alcalase, Thermolysin, and Flavourzyme. Peptide extracts obtained by the digestion of the cherry seed protein isolate with Alcalase and Thermolysin yielded the highest antioxidant and antihypertensive capacities. Ultrafiltration of hydrolysates allowed obtaining fractions with high antioxidant and antihypertensive capabilities. HPLC-Q-TOF-MS together with bioinformatics tools enabled one to identify peptides in these fractions. PMID:25599260

The digestion of cherry seed proteins was optimized, and three different enzymes were employed: Alcalase, Thermolysin, and Flavourzyme. Peptide extracts obtained by the digestion of the cherry seed protein isolate with Alcalase and Thermolysin yielded the highest antioxidant and antihypertensive capacities. Ultrafiltration of hydrolysates allowed obtaining fractions with high antioxidant and antihypertensive capabilities. HPLC-Q-TOF-MS together with bioinformatics tools enabled one to identify peptides in these fractions.

    The aim of this study was to investigate the effect of tart cherry juice on serum uric acid levels, hepatic xanthine oxidoreductase activity and two non-invasive biomarkers of oxidative stress (total antioxidant capacity and malondialdehyde concentration), in normal and hyperuricemic rats. Tart cherry juice (5 ml/kg) was given by oral gavage to rats for 2 weeks. Allopurinol (5 mg/kg) was used as a positive control and was also given by oral gavage. Data showed that tart cherry juice treatment did not cause any significant reduction in the serum uric acid levels in normal rats, but significantly reduced (P<0.05) the serum uric acid levels of hyperuricemic rats in a time-dependent manner. Tart cherry juice treatment also inhibited hepatic xanthine oxidase/dehydrogenase activity. Moreover, a significant increase (P<0.05) in serum total antioxidant capacity was observed in tart cherry juice treated-rats in both normal and hyperuricemic groups. The oral administration of tart cherry juice also led to a significant reduction (P<0.05) in MDA concentration in the hyperuricemic rats. Although the hypouricemic effect of allopurinol, as a putative inhibitor of xanthine oxidoreductase, was much higher than that of tart cherry, it could not significantly change anti-oxidative parameters. These features of tart cherry make it an attractive candidate for the prophylactic treatment of hyperuricaemia, particularly if it is to be taken on a long-term basis. Further investigations to define its clinical efficacy would be highly desirable. PMID:22691805

    The objective of this study was to evaluate the possibility of using polyphenolic extracts from cherry and blackcurrant leaves as natural antimicrobial agents in meat products. The polyphenolic composition of the extracts was analyzed and their impact on the microbial quality, lipid oxidation, color, and sensory evaluation of pork sausages was studied. Polyphenolic extracts were obtained from leaves collected in September. The total polyphenolic content in sour cherry leaf extract was 1.5 times higher than that found in blackcurrant leaf extract. Analysis of the polyphenol profile of each extract revealed two major groups: phenolic acids and flavonoids, including epigallocatechin and glycosides of quercetin and kaempferol. After chilling the sausages for 14 and 28 days, the extracts caused significantly lower MDA generation, indicating an antioxidant effect. Color changes after 28 days of storage were perceptible in the case of all treatments, with and without polyphenols. The application of sour cherry and black currant leaf extracts increased the shelf life of vacuum-packed sausages. Both extracts enhanced the microbial quality of the pork sausages over 14 days of refrigerated storage. Sour cherry leaf polyphenols were more effective against almost all studied groups of microorganisms. PMID:27375255

    Full Text Available The present study was conducted at the Felin Experi- mental Farm, belonging to the University of Life Sciences in Lublin, during the period 2005–2008. The experimental material consisted of maiden trees of sour cherry 'Łutówka' budded on seedlings of mahaleb cherry (Prunus mahaleb L. of unknown origin. The experiment evaluated the effect of four budding times: 15 July, 1 August, 15 August, and 1 September, on the quality of cherry trees in a nursery. The mean for the three years showed that budding time did not have a significant effect on the quality of cherry trees in the nursery. It was observed that the budding of mahaleb cherry performed on the two August dates (1st and 15th had a more beneficial effect on the growth and branching of trees than the budding done on 15 July and 1 September. The quality of maiden cherry trees 'Łutówka' in the nursery was primarily dependent on weather conditions in a given growing season, which is evidenced by the significant differences between production cycles, high variation in the quantitative results in individual years, and the absence of significant differences in the mean for 2006–2008.

    Nutritional compounds (phenolic compounds, L-ascorbic acid), antioxidant activities, and physicochemical characteristics (fruit weight, dry matter, soluble solids, pH, acidity, total and reducing sugars) of 33 different sour cherry cultivars were studied. Polyphenols were identified by LC-PDA-QTOF/MS and quantified by UPLC-PDA-FL. A total of 41 polyphenolic compounds found were identified and presented as 14 flavan-3-ols, 11 anthocyanins, 5 hydroxycinnamic acids, 10 flavonols, and 1 flavon. The content of total polyphenols (TPs) ranged from 2982.51 ('Wisok' cultivar) to 1539.43 mg/100 g dry weight ('Erdi Nagygyϋmϋscu'cultivar). Flavan-3-ols, the major class of sour cherry polyphenols, represented ∼ 40% of the TP compounds, whereas anthocyanins and hydroxycinnamic acids amounted for about 25% each. The content of l-ascorbic acid did not exceed 22.18 mg/100 g fresh matter. Some polish sour cherry cultivars (especially 'Agat', 'Ametyst', 'Wider', 'Winer', and 'Wisok') may be selected to promote the growth of cultivars with strong nutritional and phytochemical beneficial effects on human health.

    There is an increasing interest to bio-components obtained from fruit & vegetable wastes. Anthocyanin is one of the components regained from fruits especially from red ones. Sour cherry is considered as industrial fruit since most of the grown fruit is processed into juice and hence considerable amount of pomace is removed from process. The influences of process parameters on the extraction of phenolic compounds from sour cherry pomace were investigated. Fifty-one percent ethanol concentration, 75 °C temperature and 12 mL/g solvent to solid ratio were selected as optimum process parameters. Time effect on the process efficiency was monitored at three different temperatures (25, 50 and 75 °C) and total phenolic and total anthocyanin contents were found to reach equilibrium concentrations between 80 and 100 min time intervals. Ethanol concentrations affected differently extraction yield of anthocyanins and non-anthocyanin phenolics. Various individual phenolic compounds present in sour cherry pomace were identified and quantified by HPLC equipped with UV/Vis PDA. Of the phenolic compounds, cyanidin-3-glucosylrutinoside, neochlorogenic acid and catechin were the most abundant ones found in the pomace. 14.23 ± 0.38 mg/g total phenolic, 0.41 ± 0.02 mg/g total anthocyanin, 0.19 ± 0.02 mg/g cyanidin-3-glucosylrutinoside, 0.22 ± 0.01 mg/g neochlorogenic acid and 0.22 ± 0.02 mg/g catechin contents (dry weight) were determined in the pomace at optimum extraction conditions.

    Five Hungarian sour cherry cultivars were studied to determine their anthocyanin contents and their possible inhibitory properties. The water and methanol soluble antioxidant capacities were separately assessed by photoluminescence showing values ranged from 3.4μgmg(-1) to 15.4μgmg(-1), respectively. The "VN1" variety (selected from "Csengődi csokros") showed the highest antioxidant capacity. The anthocyanin content, measured by pH differential method or isolated by solid phase extraction, was the highest also in "VN1". Correlation was found between the anthocyanin content and the high antioxidant capacity. The main anthocyanin components were cyanidin-3-O-rutinoside and cyanidin-3-O-glucoside. The presence of malvidin-3,5-O-diglycoside was verified by MALDI-TOF MS. Sour cherry extracts and selected anthocyanins inhibited the human salivary alpha-amylase catalyzed hydrolysis competitively. The lowest IC50 value, 55μgmL(-1) or 80μM, was measured for malvidin-3,5-O-diglycoside, for which possible binding modes within the alpha-amylase active site could be investigated in silico using molecular docking and molecular dynamics.

    This study characterizes the S6m-haplotype, a mutated S6-haplotype with an altered HindIII cut site, of sour cherry (Prunus cerasus). Inheritance and pollination studies of S-haplotypes from reciprocal crosses between 'Erdi Botermo' (EB; S4S6mSa) and 'Rheinische Schattenmorelle' (RS; S6SaSbSc) revealed that the S6m-haplotype conferred unilateral incompatibility with a non-functional pistil component and a functional pollen component. Expression analyses of S6-RNase and SFB6, a candidate gene for pollen-S, in the S6m-haplotype showed that SFB6 was transcribed in EB pollen, but S6-RNase was not transcribed in EB styles. These results were consistent with data from the inheritance and pollination studies. Inverse PCR for the flanking regions of S6-RNase in the S6- and S6m-haplotypes revealed an approximately 2600 bp insertion present at approximately 800 bp upstream of the S6-RNase in the S6m-haplotype, which is responsible for the alternation of the HindIII cut site and a possible cause of inhibition of the transcription of S6-RNase. SFB6 was present downstream of S6-RNase in both the S6- and S6m-haplotypes and expressed in the same way, supporting the idea that SFB is a good candidate for pollen-S in Prunus. PMID:14512382

    The phenolic compounds of many fruits have been known to be efficient cellular protective antioxidants. In this study, antioxidative and antiviral properties of flowering cherry cultivars (Prunus yedoensis, Prunus sargentii, Prunus lannesiana, and Prunus cerasus) in Korea were investigated. The antioxidant property was assayed for specific activities including 2,2-diphenyl-1-picrylhydrazyl (DPPH) hydroxy radical scavenging activity, reducing power capacity, and superoxide dismutase (SOD) like activity. In addition, antiviral activity was determined by inhibition studies on the infection cycle of porcine epidemic diarrhea virus (PEDV), measured as minimum concentration of cherry extracts that inhibited 50% of cytopathic effect (CPE) on PEDV. Our results show that the four varieties of cherries contain substantially high antioxidants and antiviral activities. In particular, P. cerasus contains higher antioxidants and antiviral activities as well as polyphenolic content than other varieties. Our data indicate that Korean native cherry cultivars could be beneficial supplements of dietary antioxidants and natural antiviral agents. PMID:20821824

    The physicochemical characteristics of four cherry species (Prunus avium, Prunus cerasus, Prunus pseudocerasus and Prunus tomentosa) were evaluated. Inter-species variability was greater than intra-species differences. Glucose and fructose were the main sugars, and malic acid was the main organic acid in all species. Combining HPLC-DAD and LC-ESI-MS/MS technologies, total 25 phenolic components were preliminarily identified. P. avium was characterised by high fruit weight, edible proportion, sugar content and low acid content, which made it suitable for fresh eating. P. cerasus was high in acid content and anthocyanins content, making it a good processing species. P. pseudocerasus had rich flavonols varieties and high proportion of hydrocinnamic acids. P. tomentosa was characterised by high total phenolics content (especially flavonols and tannins) and antioxidant activity, indicating a great developmental potential as a health fruit. The results of the present study might provide theoretical guidance for the further development and utilisation of cherries. PMID:25466099

    Juice was manufactured from seven different sour cherry clones/cultivars and evaluated by quantitative descriptive sensory analysis and (1)H NMR spectroscopy. The sensory evaluation showed a large variation in several sensory attributes between the sour cherry clones/cultivars, which could be divided into two groups on the basis of both the sensory data and the NMR spectroscopic data. These groups were closely related to the genetic background of the clones. Kelleris clones were distinctly different from Stevnsberry and Fanal clones. Hence, (1)H NMR spectroscopic data seem to correlate with sensory quality of different sour cherry clones. In addition, malic acid was the most important metabolite for modeling the two highly correlated sensory attributes sweetness and sourness, whereas the glucose content had a slight effect and the fructose content had no impact on sweetness/sourness. Other metabolites (ethyl acetate, asparagine, ethanol) could be correlated with sensory attributes; however, a direct causal connection could not be established. PMID:21981716

  18. The effect of foliar fertilization on growth and yield of sour cherry (Prunus cerasus L. cv. Łutówka

    Full Text Available The present study, carried out in the period 2007-2009 in the Sandomierz Upland, did not show a significant effect of foliar fertilization on trunk thickness and canopy volume in the cultivar Łutówka. However, under the influence of urea applied three times in combination with Florovit at a concentration of 0.5%, a clear increasing trend was observed in the above mentioned parameters used to assess the strength of growth. In years of abundant fruiting, this study showed a significant increase, or on the verge of significance, in yield after threefold application of urea and Florovit in combination. A small insignificant effect of fertilization on fruit weight shows that the growth in yield after the application of fertilization was produced as a consequential effect of a significant increase in the length of one-year shoots and thereby in flowering intensity of the 'Łutówka' cherry trees. In the case of the sour cherry cultivar Łutówka bearing fruit on one-year shoots, foliar feeding after flowering using multi-nutrient fertilizers and urea can be recommended as a technological treatment, in particular in years of abundant fruiting.

Also, using insect-proof cages constructed around ‘Stevnsbaer’ trees, fruit set and yield were recorded and compared with self-pollination in the absence of insects and open pollination. When floral development and seasonal conditions are suitable, there is a potential role for introduced Osmia...... rufa and B. terrestris to add to the pollination activity of conventionally employed A. mellifera. However, in a season with a less favourable weather history, and despite comparable activity of the three species during the pollen-receptive period, introduced bees had only a limited effect on fruit set...

    Sour cherry seed extract (SCE) was evaluated for its capacity to inhibit lipopolysaccharide-treated human peripheral blood T cells expressing tumor necrosis factor-alpha, and the chemokine interleukin-8. Both proteins are diagnostic biomarkers for inflammatory pathologies. Peripheral blood leukocytes from 11 rheumatoid arthritis (RA) patients and 8 healthy control subjects were co-cultured for 24h in lipopolysaccharide and the extract, then evaluated by flow cytometry for T cell activation and by enzyme-linked immunoassay for lymphocyte-associated heme oxygenase-1 (HO-1) expression. There was a dose-dependent decrease in expression of the immunophenotypes: CD3+TNF-α+, and CD3+IL8+ in cultures from RA patients to a greater extent than in cells from healthy participants. These results suggest that the extract may have a modulatory roll in RA and other inflammatory disorders via the induction of HO-1, thus abating oxidative stress and strengthening regulation of pro-inflammatory signaling pathways.

    2013-01-01

    Cherry tree micropropagation is limited to the production of healthy cultivars of Prunus avium and Prunus cerasus, and their rootstocks; mainly the dwarfing ones. By using meristem-tip (0.1 mm long) or healthy shoot tips/nodes, four successive steps are needed to obtain whole plants capable of growing in the nursery: multiplication by axillary branching, shoot elongation, rooting, and plantlet acclimation. Along this process, several parameters have to be adjusted for each phase of the culture, including media composition, environmental culture conditions and plant handling. These parameters vary depending on genotypic response and specific vulnerability to physiological disorders such as hyperhydricity, apex necrosis, unstable propagation, and rooting rates. Based on a 40 year-long experience of study and application of culture conditions to large-scale plant production, this document summarizes the main problems (variability of the propagation rate, hyperhydricity, apex necrosis, plant re-growth) and solutions encountered to solve them, with means validated on many mericlones.

    We report the sequence of 41 primer pairs of microsatellites from a CT-enriched genomic library of the peach cultivar 'Merrill O'Henry'. Ten microsatellite-containing clones had sequences similar to plant coding sequences in databases and could be used as markers for known functions. For microsatellites segregating at least in one of the two Prunus F(2) progenies analyzed, it was possible to demonstrate Mendelian inheritance. Microsatellite polymorphism was evaluated in 27 peach and 21 sweet cherry cultivars. All primer pairs gave PCR-amplification products on peach and 33 on cherry (80.5%). Six PCR-amplifications revealed several loci (14.6%) in peach and eight (19.5%) in sweet cherry. Among the 33 single-locus microsatellites amplified in peach and sweet cherry, 13 revealed polymorphism both in peach and cherry, 19 were polymorphic only on peach and one was polymorphic only on cherry. The number of alleles per locus ranged from 1 to 9 for peach and from 1 to 6 on sweet cherry with an average of 4.2 and 2.8 in peach and sweet cherry, respectively. Cross-species amplification was tested within the Prunus species: Prunus avium L. (sweet cherry and mazzard), Prunus cerasus L. (sour cherry), Prunus domestica L. (European plum), Prunus amygdalus Batsch. (almond), Prunus armeniaca L. (apricot), Prunus cerasifera Ehrh. (Myrobalan plum). Plants from other genera of the Rosaceae were also tested: Malus (apple) and Fragaria (strawberry), as well as species not belonging to the Rosaceae: Castanea (chestnut tree), Juglans (walnut tree) and Vitis (grapevine). Six microsatellites gave amplification on all the tested species. Among them, one had an amplified region homologous to sequences encoding a MADS-box protein in Malus x domestica. Twelve microsatellites (29.3%) were amplified in all the Rosaceae species tested and 31 (75.6%) were amplified in all the six Prunus species tested. Thirty three (80.5%), 18 (43.9%) and 13 (31.7%) gave amplification on chestnut tree, grapevine

    Full Text Available The allergic reactions to fruits are lesser known among food sensitivities. The most common fruits belonging to the Rosaceae family that might cause allergic reactions are apples, pears and peaches. However, little is known about the potential allergic reactions caused by another member of the Rosaceae, the cherry. The aim of this study was to assess the risk of any allergic reaction or food hypersensitivity resulting from topical application and chronic oral administration of cherry fruits. The cherry fruits ‘Sabina’ cv. were produced in the orchard in Dąbrowice according to the principles of integrated (IFP and organic (OR productions. Fruits of ‘Debreceni Bötermö’ cv. were produced in Dąbrowice (IFP, and in the orchard in Nowy Dwór (OR. The experiments were performed on 65 outbred young, adult, white albinotic guinea pigs (Dankin Hartley. Three procedures were applied: I. Guinea-Pig Maximization Test (GPMT; II. Chronic administration of fruits and III. Skin prick (Dreborg test. The skin reactions based on GPMT or Dreborg tests revealed no differences between the two cherry cultivars ‘Sabina’ and ‘Debreceni’ obtained from integrated or organic production. Similarly, it was not observed of any effect of cultivars of cherries nor the type of fruits production on the guinea pig skin reaction as a result of chronic feeding with fruits.

    Striking increases in fruit size distinguish cultivated descendants from small-fruited wild progenitors for fleshy fruited species such as Solanum lycopersicum (tomato) and Prunus spp. (peach, cherry, plum, and apricot). The first fruit weight gene identified as a result of domestication and selection was the tomato FW2.2 gene. Members of the FW2.2 gene family in corn (Zea mays) have been named CNR (Cell Number Regulator) and two of them exert their effect on organ size by modulating cell number. Due to the critical roles of FW2.2/CNR genes in regulating cell number and organ size, this family provides an excellent source of candidates for fruit size genes in other domesticated species, such as those found in the Prunus genus. A total of 23 FW2.2/CNR family members were identified in the peach genome, spanning the eight Prunus chromosomes. Two of these CNRs were located within confidence intervals of major quantitative trait loci (QTL) previously discovered on linkage groups 2 and 6 in sweet cherry (Prunus avium), named PavCNR12 and PavCNR20, respectively. An analysis of haplotype, sequence, segregation and association with fruit size strongly supports a role of PavCNR12 in the sweet cherry linkage group 2 fruit size QTL, and this QTL is also likely present in sour cherry (P. cerasus). The finding that the increase in fleshy fruit size in both tomato and cherry associated with domestication may be due to changes in members of a common ancestral gene family supports the notion that similar phenotypic changes exhibited by independently domesticated taxa may have a common genetic basis.

    The effect of towns on plant phenology, i.e. advancement of spring development compared with a rural environment, via the urban heat island (UHI) phenomenon, has been shown for many towns in many countries. This work combines experimental and observational methodology to provide a better and deeper view of climatic habitat in an urban context with a view to understanding the relationship between plant development and urban climate on the intra-urban scale (by taking into account town structure). A dense network of 17 meteorological stations was set up in Rennes, France, enabling us to identify and quantify climatic changes associated with the UHI. Meanwhile, phenological observations were made during early spring (March and April) in 2005 on Platanus acerifolia and Prunus cerasus to study the relationship between climatic and phenological data. The results show that there is both a climatic gradient and a developmental gradient corresponding to the type of urbanisation in the town of Rennes. The town influences plant phenology by reducing the diurnal temperature range and by increasing the minimum temperature as one approaches the town centre. The influence of ground cover type (plants or buildings) on development is also shown. The developmental phases of preflowering and flowering are influenced to differing extents by climatic variables. The period during which climatic variables are effective before a given developmental phase varies considerably. The preflowering phases are best correlated with the mean of the minimum air temperature for the 15-day period before the observation, whereas flowering appears to be more dependent on the mean of the daily diurnal temperature range for the 8 days preceding the observation.

    Black cherry (Prunus serotina Ehrh.) is one of the most valuable hardwoods for high- end cabinetry, furniture, architectural millwork, paneling, and veneer. However, the damage caused by cambial-mining insect pests triggers gummosis in black cherry, a non-specific defense response in which resinous gum is deposited at the site of injury. The gum defects dramatically decrease the yield of high-quality black cherry lumber, and the value can be reduced by as much as 90%. The goal of this project...

    2016-01-01

    The aim of this study was to characterize 23 important Iranian sweet cherry (Prunus avium) cultivars collected from different provinces of Iran and 1 foreign cultivar, which was used as control, considered for breeding programs by using 21 microsatellite markers and 27 morphological traits. In sweet cherry (Prunus avium) accessions, leaf, fruit, and stone morphological characters were evaluated during two consecutive years. The study revealed a high variability in the set of evaluated sweet cherry accessions. The majority of important correlations were determined among variables representing fruit and leaf size and variables related to color. Cluster analysis distinguished sweet cherry accessions into two distinct groups. Principal component analysis (PCA) of qualitative and quantitative morphological parameters explained over 86.59% of total variability in the first seven axes. In PCA, leaf traits such as leaf length and width, and fruit traits such as length, width, and weight, and fruit flesh and juice color were predominant in the first two components, indicating that they were useful for the assessment of sweet cherry germplasm characterization. Out of 21 SSR markers, 16 were polymorphic, producing 177 alleles that varied from 4 to 16 alleles (9.35 on average) with a mean heterozygosity value of 0.82 that produced successful amplifications and revealed DNA polymorphisms. Allele size varied from 95 to 290 bp. Cluster analyses showed that the studied sweet cherry genotypes were classified intofive main groups based mainly on their species characteristics and SSR data. In general, our results did not show a clear structuring of genetic variability within the Iranian diffusion area of sweet cherry, so it was not possible to draw any indications on regions of provenance delimitation. The results of this study contribute to a better understanding of sweet cherry genetic variations in Iran, thus making for more efficient programs aimed at preserving biodiversity and

    In order to evaluate the role of ethyl acetate fraction (PNRS-EtOAC) obtained from the Prunus cerasus fruit in the modulation of immune responses, detailed studies were carried out using a panel of in vivo assays. Oral administration of PNRS-EtOAC (25-100 mg/kg) stimulated the IgM and IgG titre expressed in the form of hemagglutination antibody (HA) titre. Further, it elicited a dose related increase in the delayed type hypersensitivity reaction (DTH) after 24 and 48 h in BALB/c mice. Besides augmenting the humoral and cell mediated immune response, the concentration of cytokines (IFN-γ, IL-4, and TNF-α) in serum with respect to T cell interactions, i.e. the proliferation of lymphocytes were significantly increased at 50 mg/kg compared with the control. The results in these studies demonstrated the immunostimulatory effect of PNRS-EtOAC in a dose-dependent manner with respect to the macrophage activation possibly expressing the phagocytosis and nitrite production by the enhancement of TNF-α production as a mode of action.

    The classification of the economically important genus Prunus L. sensu lato (s.l.) is controversial due to the high levels of convergent or the parallel evolution of morphological characters. In the present study, phylogenetic analyses of fifteen main segregates of Prunus s.l. represented by eighty-four species were conducted with maximum parsimony and Bayesian approaches using twelve chloroplast regions (atpB-rbcL, matK, ndhF, psbA-trnH, rbcL, rpL16, rpoC1, rps16, trnS-G, trnL, trnL-F and ycf1) and three nuclear genes (ITS, s6pdh and SbeI) to explore their infrageneric relationships. The results of these analyses were used to develop a new, phylogeny-based classification of Prunus s.l. Our phylogenetic reconstructions resolved three main clades of Prunus s.l. with strong supports. We adopted a broad-sensed genus, Prunus, and recognised three subgenera corresponding to the three main clades: subgenus Padus, subgenus Cerasus and subgenus Prunus. Seven sections of subgenus Prunus were recognised. The dwarf cherries, which were previously assigned to subgenus Cerasus, were included in this subgenus Prunus. One new section name, Prunus L. subgenus Prunus section Persicae (T. T. Yü & L. T. Lu) S. L. Zhou and one new species name, Prunus tianshanica (Pojarkov) S. Shi, were proposed. PMID:23945216

    The western cherry fruit fly, Rhagoletis indifferens Curran, infests introduced, domesticated sweet [Prunus avium (L.) L.], and tart cherries (Prunus cerasus L.) as well as native bitter cherry, Prunus emarginata (Douglas) Eaton. Bitter cherries are smaller than sweet and tart cherries and this could affect various life history traits of flies. The objectives of the current study were to determine 1) if body size and egg loads of flies infesting sweet, tart, and bitter cherries differ from one another; and 2) if any observed body size differences are genetically based or caused by the host fruit environment. Pupae and adults of both sexes reared from larval-infested sweet and tart cherries collected in Washington and Montana were larger than those reared from bitter cherries. In addition, flies of both sexes caught on traps in sweet and tart cherry trees were larger than those caught in bitter cherry trees and females trapped from sweet and tart cherry trees had 54.0-98.8% more eggs. The progeny of flies from naturally-infested sweet and bitter cherries reared for one generation in the laboratory on sweet cherry did not differ in size. The same also was true for progeny of sweet and bitter cherry flies reared in the field on bitter cherry. The results suggest that the larger body sizes of flies from sweet and tart cherries than bitter cherries in the field are caused by host fruit and not genetic factors. PMID:22217749

    In Mexico black cherry (Prunus serotina Ehrh.) fruits are consumed fresh, dried or prepared in jam. Considering the evidence that has linked intake of fruits and vegetables rich in polyphenols to cardiovascular risk reduction, the aim of this study was to characterize the phenolic profile of black cherry fruits and to determine their antioxidant, vasorelaxant and antihypertensive effects. The proximate composition and mineral contents of these fruits were also assessed. Black cherry fruits possess a high content of phenolic compounds and display a significant antioxidant capacity. High-performance liquid chromatography/mass spectrometric analysis indicated that hyperoside, anthocyanins and chlorogenic acid were the main phenolic compounds found in these fruits. The black cherry aqueous extract elicited a concentration-dependent relaxation of aortic rings and induced a significant reduction on systolic blood pressure in L-NAME induced hypertensive rats after four weeks of treatment. Proximate analysis showed that black cherry fruits have high sugar, protein, and potassium contents. The results derived from this study indicate that black cherry fruits contain phenolic compounds which elicit significant antioxidant and antihypertensive effects. These findings suggest that these fruits might be considered as functional foods useful for the prevention and treatment of cardiovascular diseases. PMID:24287993

    Full Text Available Ten wild growing sweet cherry (Prunus avium L. genotypes from South-East Serbia with different fruit skin color were analyzed for its phenological, morphological and chemical traits. Agronomic evaluation of germplasm accessions revealed considerable diversity among different accessions for all the characters studied. The analysis of variance revealed significant differences among all genotypes for almost all examined properties. Cluster analysis showed adequate grouping of wild sweet cherry genotypes according to pomological characterization and distinguished them into two distinct groups. The first group had two subgroups and consisted of seven genotypes, while the second one included only three accessions. Despite of the significant differences among genotypes, the total concentration of phenols made a clear separation between the clusters. The level of genetic diversity in these wild sweet cherry genotypes is very high and therefore these trees are useful sources of variability for attributes studied and can be employed in further breeding programs or conservation.

    Full Text Available Effect of pectolyase Y-23 and cellulase Onozuka RS on the yield of viable protoplasts of Prunus cerasus L. ""Montmorency"". To isolate leaf mesophyll, leaf and root callus protoplasts of Prunus cerasus L. ""Montmorency"", we have determined the optimum enzymatic mixtures to be used, and characterized the specific activity of these enzymes. The analysis of the specific activities of enzymes allows to compare the different cellulases and pectinases used to obtain protoplasts in relation with the tissue sources. This analysis concerned the FPase (degradation of filter paper and CMCase activities for cellulases Onozuka RS and R-10, and the PME (pectinmethylesterase, PL (pectate lyase and PG (polygalacturonase activities for the pectinases Macerozyme R-10 and Pectolyase Y-23. The results show that the digestion of leaf mesophyll tissues need cellulase Onozuka RS and Pectolyase Y-23 while callus protoplasts of the same material, can be isolated with cellulase Onozuka R-10 and Macerozyme R-10. The enzymes cellulase Onozuka RS and Pectolyase Y-23 (as pectinase improved significantly the yield and the viability of leaf mesophyll protoplasts compared to cellulase Onozuka R-10 and Macerozyme R-10. These results were correlated to the specific activities of the enzymes. Significant differences between the 2 pectinases are observed for PME, PL and PG activities and between the 2 cellulases for CMCase activity. From callus, the maximum amount of viable protoplasts was obtained with cellulase Onozuka R-10 (low CMCase activity and Macerozyme R-10 (low PG activity.

    Root density was investigated using the trench method in a cherry (Prunus avium grafted on Prunus mahaleb) orchard with clean cultivation in inter-rows and in-row. Trenches of 1 m width and 1.2 m depth were dug up between neighbouring trees. The objectives of the paper were to clarify the spatial distribution of root density of cherry trees under the soil and climate conditions of the region to expand knowledge of optimum planting distance and orchard management for a broad area of chernozems. Some soil physical properties were significantly worsened in inter-rows versus in-row, mainly due to soil compaction, and there were higher root density values in in-row versus inter-rows. Root density decreased more intensely with soil depth than with distance from trees. The pattern of root density suggests that the cherry tree density and fruit yield could be increased. However, other factors concerning orchard management and fruit yield should also be considered. The results obtained have a potential impact to improve irrigation and fertilizer application by various methods, considering the soil depth and distance from trees to wet soil, in accordance with root development.

  14. Detecting local establishment strategies of wild cherry (Prunus avium L.

    2006-10-01

    Full Text Available Abstract Backround P. avium, a pioneer tree species that colonizes early forest successional stages, is assumed to require an effective strategy allowing stably repeatable rounds of local establishment, dispersal and local extinction. Consequently, the early replacement of cherry by climax tree species makes the establishment of several local generations very unlikely, especially in central European continuous cover forests. This has to be seen in connection with the mixed reproduction system involving asexual reproduction as a complementary adaptational strategy. Tests of the local establishment of wild cherry must therefore consider the possibility of first generation establishment via seedling recruitment potentially followed by an asexual generation (root suckering. Successful establishment can therefore be determined only among adult individuals with the option of detecting vegetative reproduction at these stages. To test the implied suggestion about local establishment strategies of wild cherry, nuclear microsatellites were used to analyse patterns of asexual propagation among adult stages that have been subjected to one of two major types of forest management. These management types, the historical "coppice with standards system" (CWS and the "high forest system" (HFS, can be reasonably assumed to have affected the reproduction system of P. avium. Results Clear differences were found in the reproduction pattern between two stands representing the two forest management types: 1 Clonal propagation is observed in both management systems, but with a distinctly higher frequency in the CWS. Hence, sexual recruitment as a first local generation is followed by a second asexual generation in both, whereas in the CWS there is evidence for an additional clonal generation. 2 The estimation of amounts of clonal reproduction critically depends on the assumptions about multilocus gene associations. This is revealed by the application of newly developed

    Full Text Available Prunus serotina (black cherry, commonly known in Mexico as capulín, is used in Mexican traditional medicine for the treatment of cardiovascular, respiratory, and gastrointestinal diseases. Particularly, P. serotina seeds, consumed in Mexico as snacks, are used for treating cough. In the present study, nutritional and volatile analyses of black cherry seeds were carried out to determine their nutraceutical potential. Proximate analysis indicated that P. serotina raw and toasted seeds contain mostly fat, followed by protein, fiber, carbohydrates, and ash. The potassium content in black cherry raw and toasted seeds is high, and their protein digestibility-corrected amino acid scores suggest that they might represent a complementary source of proteins. Solid phase microextraction and gas chromatography/flame ionization detection/mass spectrometry analysis allowed identification of 59 and 99 volatile compounds in the raw and toasted seeds, respectively. The major volatile compounds identified in raw and toasted seeds were 2,3-butanediol and benzaldehyde, which contribute to the flavor and odor of the toasted seeds. Moreover, it has been previously demonstrated that benzaldehyde possesses a significant vasodilator effect, therefore, the presence of this compound along with oleic, linoleic, and α-eleostearic fatty acids indicate that black cherry seeds consumption might have beneficial effects on the cardiovascular system.

    Full Text Available A new method for early selection of wild cherry clones for resistance to Phytophthora sp. is presented. Four Phytophthora species (P. cinnamomi, P. citrophthora, P. megasperma, P. alni were tested in vitro on four micropropagated cherry (Prunus avium clones, obtaining reliable and reproducible results. Variability in clones susceptibilities and in parasite virulence has been evidenced. Phytophthora citrophthora is confirmed to be a dangerous parasite, due to its capability to produce symptoms rapidly and its fitness to Mediterranean environments. On the contrary P. alni does not seem a dangerous parasite for wild cherry.

    Antioxidant activity and polyphenols were quantified in vapour-extracted juice of nine Austrian, partially endemic varieties of sweet cherry (Prunus avium): cv. 'Spätbraune von Purbach', cv. 'Early Rivers', cv. 'Joiser Einsiedekirsche', cv. 'Große Schwarze Knorpelkirsche' and four unidentified local varieties. Additionally the effect of storage was evaluated for six of the varieties. A variety showing the highest antioxidant capacity (9.64 μmol Trolox equivalents per mL), total polyphenols (2747 mg/L) and total cyanidins (1085 mg/L) was suitable for mechanical harvest and its juice did not show any losses of antioxidant capacity and total anthocyanin concentration during storage. The juice of cv. 'Große Schwarze Knorpelkirsche' had also high concentrations of total anthocyanins (873 mg/L), but showed substantial losses through storage. The local Austrian sweet cherry varieties from the Pannonian climate zone are particularly suitable for the production of processed products like cherry juice with high content of anthocyanins and polyphenols.

    Full Text Available A diet rich in fruits and vegetables is associated with a lower incidence of degenerative diseases (such as cardiovascular disease and certain types of cancers. Currently, most research is focused on the content of polyphenols and antioxidant compounds found in fruit and vegetable. Sweet cherries (Prunus avium L. contain a significant amount of polyphenols and several antioxidants that possess many biological activities such as anticancer, antioxidant and anti-inflammation properties. In present study were investigated the quantification of total polyphenols and antioxidant capacity in fruits of a number of selected sweet cherry genotypes. Although sweet cherry fruits are a significant source of different phenolic compounds, antioxidant activity of sweet cherries is not related only with the total phenolic content.

    Full Text Available It is admitted that the lack of winter chilling is a limiting factor for the cultivation of temperate fruit trees in warm climates. Nevertheless, the characteristics of dormancy in sweet cherry under such conditions are still not fully understood. Therefore, and in order to contribute to the elucidation of these mechanisms, the objective of this work is to evaluate the dormancy of sweet cherry (Prunus avium L. under the Mediterranean conditions of Meknes region (Morocco. Evaluation of dormancy behaviour of four varieties was made on the basis of a biological test, known as the « single node cuttings », and histological dissections of flower buds at the time of bud break. The variations of mean time to bud break (MTB were interpreted in terms of the evolution of growth capacity of the buds. The lack of cold affected tree phenological development. The evolution of dormancy in cherry buds showed three phases with variable levels of inertia: the first and third phases being of similar intensity and duration while the second phase was of a high level of inertia (endo-dormancy. The correlative inhibitions of the leaves imposed on the buds continued up to the arrival of continuous low temperatures. The delay in the decrease of inertia reveals insufficient chilling accumulation causing incomplete release from dormancy and low bud break percentage in the orchard. Histological observations showed that vascular connection of flower buds was established during bud break stage. However, flowers showed certain abnormalities, ie low pollen production and malformations of pistils, which limit the possibilities of pollination.

    Full Text Available Knowledge of genetic and adaptive traits of reproductive materials used in the nursery system of wild cherry, could be an useful instrument to improve ecological and economic sustainability of plantation ecosystems. This work reports results from a research which the objectives were: 1 to study the genetic variation of a Prunus avium L. Population, used for seed harvesting, through its multi-locus genotypes detected by starch gel electrophoresis; 2 to analyze the level of genetic variation within and among different steps in a commercial nursery system (basic population and sub-populations, seedlings aged S1T1 and S1T2, plantation. Results showed low genetic variation levels of the basic population, similar to a reference system of other 12 wild cherry Italian populations and to other French and Caucasian materials. The genetic distances among Monte Baldo and some closer Lombardy provenances (Area Garda, Bosco Fontana, Valtellina were smaller than the Venice Region populations (Monti Lessini and Asiago. Number of alleles and percentage of polymorphic loci within the complex of Monte Baldo provenance and multiplication materials were similar, whilst a variable value of Fis was noted. Indeed, along with the nursery system until the plantation, heterozygosis initially (S1T1 increased, then decreased proceeding to the plantation. This fluctuation of FIS values could be determined by seed lots characterized initially by higher levels of variation, due to self-incompatibility. In the following steps, a possible selection pressure can affect randomly the genotypic structure of wild cherry by increasing the homozygosity. There is not among population a well defined geographic characterization, as suggested by genetic distances, therefore homogeneous seed harvest could be established an area larger than geographic and administrative borders. On this way we could have reproductive material with a wide genetic base and environmental adaptability. To

    Prunus is a genus of trees and shrubs, including the plums, cherries, peaches, apricots and almonds. Nearly five hundred seventy chemical compounds have so far been isolated from several Prunus species. This comprehensive review summarizes the isolation of chemical compounds reported during the period 1908 to June 2010. As per scrutiny of literature, we did not find any review on the chemistry or biology of genus Prunus or on the biological activities of its constituents. Extensive work has been done at the Department of Chemistry, University of Delhi by several groups on the isolation, identification, biological activity evaluation and synthesis of a large number of novel compounds from different Prunus species during the the last six decades (1940-2000), primarly by Seshadri, Nagarajan and Parmar et al. on P. domestica, P. cerasus, P. cerasoides, P. puddum and P. communis. This comprehensive review will benefit a large number of researchers in the fields of chemistry, botany, drug industries and pharmacology. PMID:21831039

    Full Text Available Most previous studies on genetic fingerprinting and cultivar relatedness in sweet cherry were based on isoenzyme, RAPD and SSR markers. This study was carried out to assess the utility of SNP markers generated from 3’UTRs for genetic fingerprinting in sweet cherry. A total of 114 sweet cherry germplasm representing advanced selections, commercial cultivars and old cultivars imported from different parts of the world were screened with 7 SSR markers developed from other Prunus species and with 40 SNPs obtained from 3’UTR sequences of Rainier and Bing sweet cherry cultivars. Both types of marker study had 99 accessions in common. The SSR data was used to validate the SNP results. Results showed that the average number of alleles per locus, mean observed heterozygosity, expected heterozygosity and polymorphic information content (PIC values were higher in SSRs than in SNPs although both set of markers were similar in their grouping of the sweet cherry accessions as shown in the dendrogram. SNPs were able to distinguish sport mutants from their wild type germplasm. For example, ‘Stella’ was separated from ‘Compact Stella’. This demonstrates the greater power of SNPs for discriminating mutants from their original parents than SSRs. In addition, SNP markers confirmed parentage and also determined relationships of the accessions in a manner consistent with their pedigree relationships. We would recommend the use of 3’ UTR SNPs for genetic fingerprinting, parentage verification, gene mapping and study of genetic diversity in sweet cherry.

    2016-05-25

    The somaclonal variant HS, from sweet cherry (Prunus avium L.) 'Hedelfinger' (H), was previously selected for reduced tree vegetative vigor and lesser canopy density. In this work, we compared H and HS fruits at early unripe (green) and full ripe (dark red) stages by biochemical and proteomic approaches. The main biochemical parameters showed that fruit quality was not affected by somaclonal variation. The proteomic analysis identified 39 proteins differentially accumulated between H and HS fruits at the two ripening stages, embracing enzymes involved in several pathways, such as carbon metabolism, cell wall modification, stress response, and secondary metabolism. The evaluation of fruit phenolic composition by mass spectrometry showed that HS sweet cherries have higher levels of procyanidin, flavonol, and anthocyanin compounds. This work provides the first proteomic characterization of fruit ripening in sweet cherry, revealing new positive traits of the HS somaclonal variant. PMID:27144542

    Full Text Available A plantation collection containing 32 genotypes selected from spontaneous populations of cherry plum Prunus cerasifera Erhr. was set up in the region of the Eastern Serbian town of Svrljig. The fruit trees budded from Prunus cerasifera seedlings and were planted at 5x4 m spacing on a mild slope of south-western aspect. This study shows the most important characteristics of the 19 selections in the collection, and the average results recorded in the 2000-2003 period. The most significant characteristics of the trees, their productivity, and fruit and stone characteristics are presented. The average coarseness of fruits, i.e. their length, width and thickness, measured 25.0x 24.4x25.0 mm, while stone coarseness was 14.4x10.3x3.6 mm. The average fruit weight was 12.1 g (24.3-4.8 g, and stone weight 0.85 g (2.2-0.3 g. Depending on fruit and stone weight, the mesocarp content was 93% (96.3-90.3%. Taking into consideration the possibility of fruit exploitation for the production of biologically high-quality food, the mesocarp chemical composition was thoroughly examined. The fruits were found to have increased contents of total acids, achieving an average of 3.09% (3.44-2.60%, which was the initial objective of this selection. Total solids content was 13.5% (16.2-10.3%, total soluble solids 12.5% (14.5-9.5% and total sugars 6.00% (11.45-3.14%. Considering these characteristics, the selections that were singled out deserve more attention in terms of preserving their biodiversity, forming a gene bank and commercial cultivation.

Two pollen viability tests, TTC (2,3,5-triphenyl tetrazolium chloride and IKI (iodine potassium iodide, were used. Pollen traits of genotypes were studied using an in vitro medium containing 0%, 5%, 10%, 15%, and 20% sucrose to determine the best sucrose concentrations for germination. In the second step, the germinated pollen was counted 1, 4, 6, 10, 12, 24, and 48 hours later until there was no further germination. The viability rates were different according to genotypes and tests used. The IKI and TTC staining tests and pollen germination had low correlation (r2 = 0.0614 and r2 = 0.0015, resp.. Painted pollen rate was higher and pollen was well-stained with IKI test and pollen viability estimated with TTC staining test was better than that estimated with the IKI staining test. 15% sucrose gave the best germination rates in most of the genotypes. Pollen germination rates were recorded periodically from one hour to 48 hours in 15% sucrose and the results showed that pollen germination rates increased after 6 hours of being placed in culture media.

  17. The African cherry (Prunus africana): can lessons be learned from an over-exploited medicinal tree?

    For the last 35 years, the African cherry (Prunus africana (Hook. f.) Kalm.) has been used in the treatment of benign prostatic hyperplasia and other disorders. The bark, from which the treatment is derived, is entirely wild-collected. The major exporters of bark include Cameroon, Madagascar, Equatorial Guinea, and Kenya. Groupe Fournier of France and Indena of Italy produce 86% of the world's bark extract, both for their own products and for the free market. Worldwide exports of dried bark in 2000 have been estimated at 1350-1525 metric tons per year, down from its peak of 3225 tons in 1997. Bark extracts (6370-7225 kg per year) are worth an estimated $4.36 million US dollars per year. In 2000, Plantecam, the largest bark exporter in Africa, closed its extraction factory in Cameroon, due to complex ecological, social, and economic factors. Wild-collection is no longer sustainable (and probably never was) where harvest seriously affects morbidity and mortality rates of harvested populations. Since 1995, it has been included in CITES Appendix II as an endangered species. In this paper, alternatives to wild-collection to meet future market demand are investigated, including conservation practices, enrichment plantings, small- and large-scale production, and protection of genetic resources. The species is at the beginning of a transition from an exclusively wild-collected species to that of a cultivated medicinal tree.

    Trees of 'Sweet Heart' and 'Sweet Late' sweet cherry cultivars (Prunus avium L.) were treated with oxalic acid (OA) at 0.5, 1.0, and 2.0 mM at 98, 112, and 126 days after full blossom. Results showed that all treatments increased fruit size at harvest, manifested by higher fruit volume and weight in cherries from treated trees than from controls, the higher effect being found with 2.0 mM OA (18 and 30% higher weight for 'Sweet Heart' and 'Sweet Late', respectively). Other quality parameters, such as color and firmness, were also increased by OA treatments, although no significant differences were found in total soluble solids or total acidity, showing that OA treatments did not affect the on-tree ripening process of sweet cherry. However, the increases in total anthocyanins, total phenolics, and antioxidant activity associated with the ripening process were higher in treated than in control cherries, leading to fruit with high bioactive compounds and antioxidant potential at commercial harvest (≅45% more anthocyanins and ≅20% more total phenolics). In addition, individual anthocyanins, flavonols, and chlorogenic acid derivatives were also increased by OA treatment. Thus, OA preharvest treatments could be an efficient and natural way to increase the quality and functional properties of sweet cherries. PMID:24684635

    Full Text Available The breakdown of self-incompatibility, which could result from the accumulation of non-functional S-haplotypes or competitive interaction between two different functional S-haplotypes, has been studied extensively at the molecular level in tetraploid Rosaceae species. In this study, two tetraploid Chinese cherry (Prunus pseudocerasus cultivars and one diploid sweet cherry (Prunus avium cultivar were used to investigate the ploidy of pollen grains and inheritance of pollen-S alleles. Genetic analysis of the S-genotypes of two intercross-pollinated progenies showed that the pollen grains derived from Chinese cherry cultivars were hetero-diploid, and that the two S-haplotypes were made up of every combination of two of the four possible S-haplotypes. Moreover, the distributions of single S-haplotypes expressed in self- and intercross-pollinated progenies were in disequilibrium. The number of individuals of the two different S-haplotypes was unequal in two self-pollinated and two intercross-pollinated progenies. Notably, the number of individuals containing two different S-haplotypes (S1- and S5-, S5- and S8-, S1- and S4-haplotype was larger than that of other individuals in the two self-pollinated progenies, indicating that some of these hetero-diploid pollen grains may have the capability to inactivate stylar S-RNase inside the pollen tube and grow better into the ovaries.

The genome size is 157 786 bp in length with 36.7% GC content, which is composed of LSC region of 85 908 bp, SSC region of 19 120 bp and two IR copies of 26 379 bp each. The cp genome contains 131 genes, including 86 coding genes, 8 rRNA genes and 37 tRNA genes. The maximum likelihood analysis was conducted to verify a phylogenetic position of the newly sequenced cp genome of P. yedoensis using 11 representatives of complete cp genome sequences within the family Rosaceae. The genus Prunus exhibited monophyly and the result of the phylogenetic relationship agreed with the previous phylogenetic analyses within Rosaceae. PMID:26329800

    Microsatellite markers were used to describe the genetic variability of four seed stands of wild cherry (Prunus avium L.). One hundred and thirty one individuals were genotyped at ten nuclear microsatellite loci. Total genetic diversity was high (H(E) = 0.704), while differences between stands were small but significant (F(ST) = 0.053, G'(ST) = 0.234). There was a significant amount of clonal reproduction in one stand, with only 11 genotypes identified among 36 trees. One stand showed a signi...

    We conducted SSR analyses of 59 accessions, including 29 traditional plum (Prunus domestica), 24 sweet cherry (Prunus avium), and 1 sour cherry (Prunus cerasus) selected from East Anatolian gene sources and 3 plum and 2 cherry reference accessions for molecular characterization and investigation of genetic relationships. Eight SSR loci [1 developed from the apricot (UDAp-404), 4 from the peach (UDP96-010, UDP96-001, UDP96-019, Pchgms1) and 3 from the cherry (UCD-CH13, UCD-CH17, UCD-CH31) genome] for plum accessions and 9 SSR loci [5 developed from the cherry (PS12A02, UCD-CH13, UCD-CH17, UCD-CH31, UCD-CH21), 3 from the peach (Pchgms1, UDP96-001, UDP96-005) and 1 from the plum (CPSCT010) genome] for cherry accessions were used for genetic identification. A total of 66 and 65 alleles were obtained in the genetic analyses of 31 plum and 28 cherry accessions, respectively. The number of alleles revealed by SSR analysis ranged from 4 to 14 alleles per locus, with a mean value of 8.25 in plum accessions, and from 5 to 10 alleles per locus with a mean value of 7.2 in cherry accessions. Only one case of synonym was identified among the cherry accessions, while no case of synonym was observed among the plum accessions. Genomic SSR markers used in discrimination of plum and cherry accessions showed high cross-species transferability in the Prunus genus. Because of their appreciable polymorphism and cross species transferability, the SSR markers that we evaluated in this study will be useful for studies involving fingerprinting of cherry and plum cultivars.

    Most previous studies on genetic fingerprinting and cultivar relatedness in sweet cherry were based on isoenzyme, RAPD, and simple sequence repeat (SSR) markers. This study was carried out to assess the utility of single nucleotide polymorphism (SNP) markers generated from 3′ untranslated regions (UTR) for genetic fingerprinting in sweet cherry. A total of 114 sweet cherry germplasm representing advanced selections, commercial cultivars, and old cultivars imported from different parts of the world were screened with seven SSR markers developed from other Prunus species and with 40 SNPs obtained from 3′ UTR sequences of Rainier and Bing sweet cherry cultivars. Both types of marker study had 99 accessions in common. The SSR data was used to validate the SNP results. Results showed that the average number of alleles per locus, mean observed heterozygosity, expected heterozygosity, and polymorphic information content values were higher in SSRs than in SNPs although both set of markers were similar in their grouping of the sweet cherry accessions as shown in the dendrogram. SNPs were able to distinguish sport mutants from their wild type germplasm. For example, “Stella” was separated from “Compact Stella.” This demonstrates the greater power of SNPs for discriminating mutants from their original parents than SSRs. In addition, SNP markers confirmed parentage and also determined relationships of the accessions in a manner consistent with their pedigree relationships. We would recommend the use of 3′ UTR SNPs for genetic fingerprinting, parentage verification, gene mapping, and study of genetic diversity in sweet cherry. PMID:22737155

    Physical characteristics, antioxidant activity and chemical constituents of 12 cultivars (Prunus avium L.) of sweet cherry (Belge, Bing, Dalbasti, Durona di Cesena, Lambert, Merton Late, Starks Gold, Summit, Sweetheart, Van, Vista, and 0-900 Ziraat) were investigated. Significant differences (P anthocyanin contents. Belge cultivar showed the highest levels of total phenolic and anthocyanin, while Starks Gold contained the lowest level of anthocyanins. The darker cultivars, measured by ABTS(+•) , DPPH(•) and FRAP, exhibited higher antioxidant activities than the lighter ones. Bing (42.78 g/kg) and Sweetheart (40.53 g/kg) cultivars contained higher levels of malic acid, which was the most intense organic acid in sweet cherries. Four different sugars were observed in the samples and their concentrations ordered as glucose > fructose > sucrose > xylose. Sugar alcohol in the cherries was represented by sorbitol (more than 90%) and its concentration varied between 13.93 and 27.12 g/kg. As a result significant differences were observed among the physical properties and chemical constituents of the cherry cultivars. PMID:25631389

    The biochemical processes underlying firmness loss of sweet cherry (Prunus avium L.) fruit are poorly understood. Studies on cell wall metabolism of sweet cherry have been generally undertaken during on-tree development or at harvest maturity, while published reports on postharvest changes are scarce and fragmentary. In this work, cell wall modifications after storage at 0 ℃ were studied in two cherry cultivars ('Celeste' and 'Somerset') displaying different postharvest potential. Firmness was largely determined by the yields of the Na2CO3- and KOH-soluble fractions, enriched in covalently-bound pectins and in matrix glycans, respectively, and correlated well with ascorbic acid contents. The yields of these two cell wall fractions were correlated inversely with pectinmethylesterase and endo-1,4-β-d-glucanase activities, indicating a relevant role of these two enzymes in postharvest firmness changes in sweet cherry. The amount of solubilised cell wall materials was closely associated to the contents of dehydroascorbic acid, suggesting the possible involvement of oxidative mechanisms in cell wall disassembly. These data may help understanding the evolution of fruit quality during the marketing period, and give hints for the design of suitable management strategies to preserve key attributes.

    The incompatibility genetics of sour cherry ( Prunus cerasus), an allotetraploid species thought to be derived from sweet cherry (diploid) and ground cherry (tetraploid), were investigated by test crossing and by analysis of stylar ribonucleases which are known to be the products of incompatibility alleles in sweet cherry. Stylar extracts of 36 accessions of sour cherry were separated electrophoretically and stained for ribonuclease activity. The zymograms of most accessions showed three bands, some two or four. Of the ten bands seen, six co-migrated with bands that in sweet cherry are attributed to the incompatibility alleles S(1), S(3), S(4), S(6, ) S(9) and S(13). 'Cacanski Rubin', 'Erdi Botermo B', 'Koros' and 'Ujfehertoi Furtos', which showed bands apparently corresponding to S(1) and S(4), were test pollinated with the sweet cherry 'Merton Late' ( S(1) S(4)). Monitoring pollen tube growth, and, in one case, fruit set, showed that these crosses were incompatible and that the four sour cherries indeed have the alleles S(1) and S(4). Likewise, test pollination of 'Marasca Piemonte', 'Marasca Savena' and 'Morello, Dutch' with 'Noble' ( S(6) S(13)) showed that these three sour cherries have the alleles S(6) and S(13). S(13) was very frequent in sour cherry cultivars, but is rare in sweet cherry cultivars, whereas with S(3) the situation is reversed. It was suggested that the other four bands are derived from ground cherry and one of these, provisionally attributed to S(B), occurred frequently in a small set of ground cherry accessions surveyed. Analysing some progenies from sour by sweet crosses by S allele-specific PCR and monitoring the success of some sweet by sour crosses were informative. They indicated mostly disomic inheritance, with sweet cherry S alleles belonging to one locus and, presumably, the ground cherry alleles to the other, and helped clarify the genomic arrangement of the alleles and the interactions in heteroallelic pollen.

    Cherry rusty mottle is a disease of sweet cherries first described in 1940 in western North America. Because of the graft-transmissible nature of the disease, a viral nature of the disease was assumed. Here, the complete genomic nucleotide sequences of virus isolates from two trees expressing cherry rusty mottle disease symptoms are characterized; the virus is designated cherry rusty mottle associated virus (CRMaV). The biological and molecular characteristics of this virus in comparison to those of cherry necrotic rusty mottle virus (CNRMV) and cherry green ring mottle virus (CGRMV) are described. CRMaV was subsequently detected in additional sweet cherry trees expressing symptoms of cherry rusty mottle disease. PMID:23525699

    Sour cherry (Prunus cerasus) in the genus Prunus in the family Rosaceae is one of the most popular stone fruit trees worldwide. Of known sour cherry cultivars, the Schattenmorelle is a famous old sour cherry with a high amount of fruit production. The Schattenmorelle was selected before 1650 and described in the 1800s. This cultivar was named after gardens of the Chateau de Moreille in which the cultivar was initially found. In order to identify new genes and to develop genetic markers for sour cherry, we performed a transcriptome analysis of a sour cherry. We selected the cultivar Schattenmorelle, which is among commercially important cultivars in Europe and North America. We obtained 2.05 GB raw data from the Schattenmorelle (NCBI accession number: SRX1187170). De novo transcriptome assembly using Trinity identified 61,053 transcripts in which N50 was 611 bp. Next, we identified 25,585 protein coding sequences using TransDecoder. The identified proteins were blasted against NCBI's non-redundant database for annotation. Based on blast search, we taxonomically classified the obtained sequences. As a result, we provide the transcriptome of sour cherry cultivar Schattenmorelle using next generation sequencing.

    Thirty four varieties of sour cherries (Prunus cerasus) were investigated for their total antioxidant activity, Caco-2 cancer cell proliferation inhibitory activity and effect on prostaglandin E2 (PGE2) production. Total phenolic content, oxygen radical absorbance capacity (ORAC) and cancer cell proliferation inhibitory activity of sour cherries were closely correlated but not PGE2 production. The cultivars 'Birgitte × Böttermö', 'Fanal' and 'Tiki' were the three cultivars with the highest ORAC values (180, 147 and 133 µmol TE/g, respectively) and inhibition against Caco-2 cancer cell proliferation (74%, 79% and 73%, respectively). 'Stevnsbaer Birgitte' (22%) and 'Stevnsbaer Viki' (22%) inhibited PGE2 production with a similar potency as the positive controls indomethacin and NS-398. Significant differences between cultivars in all bioactivity experiments indicated that selection of cultivars is important to obtain sour cherries with better potential health promoting effects.

    Processing of fruits and vegetables affects their phytochemical and nutrient content. Tart cherries are commercially promoted to possess antioxidant and anti-inflammatory activity. However, processing affects their phytochemical content and may affect their related health benefits. The current study compares the in vitro antioxidant capacity and anti-inflammatory cyclooxygenase activity of processed tart cherry (Prunus cerasus) products-cherry juice concentrate, individually quick-frozen cherries, canned cherries, and dried cherries. Cherry products were analyzed for total anthocyanin and proanthocyanidin content and profile. On a per serving basis, total anthocyanins were highest in frozen cherries and total proanthocyanidins were highest in juice concentrate. Total phenolics were highest in juice concentrate. Juice concentrate had the highest oxygen radical absorbance capacity (ORAC) and peroxynitrite radical averting capacity (NORAC). Dried cherries had the highest hydroxyl radical averting capacity (HORAC) and superoxide radical averting capacity (SORAC). Processed tart cherry products compared very favorably to the U.S. Dept. of Agriculture-reported ORAC of other fresh and processed fruits. Inhibition of in vitro inflammatory COX-1 activity was greatest in juice concentrate. In summary, all processed tart cherry products possessed antioxidant and anti-inflammatory activity, but processing differentially affected phytochemical content and in vitro bioactivity. On a per serving basis, juice concentrate was superior to other tart cherry products. PMID:23163942

    Full Text Available This paper presents morphological indicators of the quality of one-year-old seedlings of wild cherry (Prunus avium L. with special reference to their correlations. The examined parameters were: length, diameter, weight of the aboveground and underground parts, number of buds, root volume, root length and leaf area. The ratio of heights was determined on the basis of the parameters derived: diameter, and the ratio of aboveground and underground parts of a seedling and the Quality Index. Height and diameter have proven to be good indicators of quality. Root volume has proven to be a better indicator of the quality of seedlings than root length. The weight ratio of the aboveground and underground parts of broadleaved trees in the dry state must be defined in advance, both when the measurements are carried out with and without leaves. The Quality Index has proven to be the most comprehensive morphological indicator of quality.

The typical symptom was brown spot formed on the fruit surface. The spot spread quickly through the whole fruits, then the fruits were rotten. There were tomentum round shaped mildew formed on the surface of symptomatic fruits. The pathogen was isolated from infected fruits. After pathogenicity tests in lab and field and re-isolation, the isolate HI was determined to be responsible for the disease. HI colony on PDA was 70 -75 mm in diameter, with concentric rings in grayish or light brown color after 7 days incubation at 221 with illumination of 12 h near-UV/12 h dark. The conidia were one-celled, hyaline, lemon-shaped, (10-27) jun x (7-17) jun on PDA, produced in branched monilioid chains. The rDNA ITS sequence of islolates HI and Gl had 100% similarity with those of Monilinia fructicola in GenBank. The amplification results with three Monilinia specific primer pairs showed that only primer pair ITSlMfcl and ITS4Mfcl could amplify a 356 bp fragment. Based on the morphological characteristics and rDNA molecular analysis, the pathogen was finally identified as M. Fructicola.

    Ten SSR loci, previously developed for Prunus, were analyzed to examine genetic relationships among 23 rootstock candidates for sweet and sour cherries, of the species P. avium, P. cerasus, P. mahaleb, and P. angustifolia. Five genotypes of P. laurocerasus, not used as rootstock, were included in the molecular analysis. The number of alleles per locus ranged from 8 to 12, with a mean of 9, while the number of microsatellite genotypes varied from 8 to 17, indicating that the SSRs were highly informative. The degree of heterozygosity (0.61) was high. Clustering analysis resulted in two main clusters. The first cluster was divided into two subclusters; the first subcluster consisted of P. avium and P. cerasus, and the second subcluster consisted of P. laurocerasus. The second cluster was divided into two subclusters. The first subcluster consisted of P. mahaleb genotypes and the second consisted of P. angustifolia genotypes. The reference rootstocks also clustered with their associated botanical species. Unweighted pair-group method with arithmetic mean analysis demonstrated that P. laurocerasus genotypes had less genetic variation and that P. avium genotypes were more closely related to P. cerasus. The SSR-based phylogeny was generally consistent with Prunus taxonomy information, suggesting the applicability of SSR analysis for genotyping and phylogenetic studies in the genus Prunus.

    The fruit quality characteristics, phenolic compounds and antioxidant capacities of 24 sweet cherry (Prunus avium L.) cultivars grown on the mountainsides of the Etna volcano (Sicily, Italy) were evaluated. High-performance liquid chromatographic methods were used to identify and quantify sugars, organic acids and phenolics. A total of seven phenolic compounds were characterised as hydroxycinnamic acid derivatives (neochlorogenic acid, p-coumaroylquinic acid and chlorogenic acid) and anthocyanins (cyanidin 3-glucoside, cyanidin 3-rutinoside, pelargonidin 3-rutinoside and peonidin 3-rutinoside). The total anthocyanin content ranged from 6.21 to 94.20mg cyanidin 3-glucoside equivalents/100g fresh weight (FW), while the total phenol content ranged from 84.96 to 162.21mg gallic acid equivalents/100g FW. The oxygen radical absorbance capacity (ORAC) assay indicated that fruit of all genotypes possessed considerable antioxidant activity. The high level of phenolic compounds and antioxidant capacity of some sweet cherry fruits implied that they might be sources of bioactive compounds that are relevant to human health. PMID:23692746

    Gametophytic self-incompatibility (GSI) in sweet cherry is determined by a locus S with multiple alleles. In the style, the S-locus codifies for an allele-specific ribonuclease ( S-RNase) that is involved in the rejection of pollen that carries the same S allele. In this work we report the cloning and genomic DNA sequence analysis including the 5' flanking regions of four S-RNases of sweet cherry ( Prunus avium L., Rosaceae). DNA from the cultivars Ferrovia, Pico Colorado, Taleguera Brillante and Vittoria was amplified through PCR using primers designed in the conserved sequences of sweet cherry S-RNases. Two alleles were amplified for each cultivar and three of them correspond to three new S-alleles named S23, S24 and S25 present in 'Pico Colorado', 'Vittoria' and 'Taleguera Brillante' respectively. To confirm the identity of the amplified fragments, the genomic DNA of these three putative S-RNases and the allele S12 amplified in the cultivar Ferrovia were cloned and sequenced. The nucleotide and deduced amino-acid sequences obtained contained the structural features of rosaceous S-RNases. The isolation of the 5'-flanking sequences of these four S-RNases revealed a conserved putative TATA box and high similarity among them downstream from that sequence. However, similarity was low compared with the 5'-flanking regions of S-RNases from the Maloideae. S6- and S24-RNase sequences are highly similar, and most amino-acid substitutions among these two RNases occur outside the rosaceous hypervariable region (RHV), but within another highly variable region. The confirmation of the different specificity of these two S-RNases would help elucidate which regions of the S-RNase sequences play a role in S-pollen specific recognition.

    Full Text Available During the period 2006–2009 in Lublin, a study was conducted to determine the effect of five rootstocks: ‘Colt’, ‘F12/1’, sweet cherry (Prunus avium L., ‘GiSelA 5’, and ‘Piast’, on bud take in the cultivar ‘Regina’, the quality of budded trees and the efficiency of a sweet cherry tree nursery. The highest percentage of bud take in cherry trees cv. ‘Regina’ and the best efficiency of the sweet cherry tree nursery were obtained for the rootstocks ‘Piast’ and ‘Colt’. In two years during the three-year study period, the rootstock was found to significantly affect the efficiency of the sweet cherry tree nursery. When grafted on the rootstocks ‘Colt’ and ‘Piast’, a significantly higher percentage of trees met the requirements of the Polish Standard PN-R-67010 than on the clonal rootstock ‘GiSelA 5’. Under the tested conditions, the quality of maiden sweet cherry trees cv. ‘Regina’ grafted on the dwarfing rootstock ‘GiSelA 5’ was lowest.

    Full Text Available The timing of flowering in perennial plants is crucial for their survival in temperate climates and is regulated by the duration of bud dormancy. Bud dormancy release and bud break depend on the perception of cumulative chilling during endodormancy and heat during the bud development. The objectives of this work were to identify candidate genes involved in dormancy and flowering processes in sweet cherry, their mapping in two mapping progenies 'Regina' × 'Garnet' and 'Regina' × 'Lapins', and to select those candidate genes which co-localized with quantitative trait loci (QTLs associated with temperature requirements for bud dormancy release and flowering. Based on available data on flowering processes in various species, a list of 79 candidate genes was established. The peach and sweet cherry orthologs were identified and primers were designed to amplify sweet cherry candidate gene fragments. Based on the amplified sequences of the three parents of the mapping progenies, SNPs segregations in the progenies were identified. Thirty five candidate genes were genetically mapped in at least one of the two progenies and all were in silico mapped. Co-localization between candidate genes and QTLs associated with temperature requirements and flowering date were identified for the first time in sweet cherry. The allelic composition of the candidate genes located in the major QTL for heat requirements and flowering date located on linkage group 4 have a significant effect on these two traits indicating their potential use for breeding programs in sweet cherry to select new varieties adapted to putative future climatic conditions.

    The timing of flowering in perennial plants is crucial for their survival in temperate climates and is regulated by the duration of bud dormancy. Bud dormancy release and bud break depend on the perception of cumulative chilling during endodormancy and heat during the bud development.

    The aim of this research was to study the effect of pulsed electric fields (PEF) on the flavour profile of red-fleshed sweet cherries (Prunus avium variety Stella). The cherry samples were treated at a constant pulse frequency of 100 Hz, a constant pulse width of 20 μs, different electric field strengths between 0.3 and 2.5 kV/cm and specific energy ranging from 31 to 55 kJ/kg. Volatile compounds of samples were analysed using an automated headspace solid phase microextraction (HS-SPME) method coupled with gas chromatography-mass spectrometry (GC-MS). A total of 33 volatile compounds were identified with benzaldehyde, hexanal, (E)-2-hexenal, (Z)-2-hexen-1-ol, and benzyl alcohol being the predominant volatiles in different PEF-treated samples. Aldehydes namely butanal, octanal, 2-octenal, and nonanal, and (Z)-2-hexen-1-ol increased significantly 24 h after PEF treatment at electric field strengths of more than 1.0 kV/cm. Samples incubated for 24 h after PEF treatment (S3) generated higher concentrations of volatiles than samples immediately after PEF treatments (S2). Quantitative results revealed that more flavour volatiles were released and associated with S3 samples after 24 h storage and S2 samples immediately after PEF both with the highest electric field intensities. Interestingly, this study found that the PEF treatments at the applied electric field strength and energy did not result in releasing/producing undesirable flavour compounds. PMID:25806548

    Despite senescence-induced chlorophyll depletion in plants has been widely studied, the enzymatic background of this physiologically regulated process still remains highly unclear. The purpose of this study was to determine selected biochemical properties of partially purified fractions of chlorophyllase (Chlase, chlorophyll chlorophyllido-hydrolase, EC 3.1.1.14) from leaves of three Prunus species: bird cherry (Prunus padus L.), European plum (Prunus domestica L.), and sour cherry (Prunus cerasus L.). Secondarily, this report was aimed at comparing seasonal dynamics of Chlase activity and chlorophyll a (Chl a) content within investigated plant systems. Molecular weight of native Chlase F1 has been estimated at 90 kDa (bird cherry) and approximately 100 kDa (European plum and sour cherry), whereas molecular mass of Chlase F2 varied from 35 kDa (European plum) to 60 kDa (sour cherry). Furthermore, enzyme fractions possessed similar optimal pH values ranging from 7.6 to 8.0. It was found that among a broad panel of tested metal ions, Hg(+2), Fe(+2), and Cu(+2) cations showed the most pronounced inhibitory effect on the activity of Chlase. In contrast, the presence of Mg(+2) ions influenced a subtle stimulation of the enzymatic activity. Importantly, although Chlase activity was negatively correlated with the amount of Chl a in leaves of examined Prunus species, detailed comparative analyses revealed an incidental decrement of enzymatic activity in early or moderately senescing leaves. It provides evidence that foliar Chlase is not the only enzyme involved in autumnal chlorophyll breakdown and further in-depth studies elucidating this catabolic process are required. PMID:23894730

    Chinese cherry (Prunus pseudocerasus Lindl.) is a commercially valuable fruit crop in China. In order to obtain new insights into its evolutionary history and provide valuable recommendations for resource conservation, phylogeographic patterns of 26 natural populations (305 total individuals) from six geographic regions were analyzed using chloroplast and nuclear DNA fragments. Low levels of haplotype and nucleotide diversity were found in these populations, especially in landrace populations. It is likely that a combined effect of botanical characteristics impact the effective population size, such as inbreeding mating system, long life span, as well as vegetative reproduction. In addition, strong bottleneck effect caused by domestication, together with founder effect after dispersal and subsequent demographic expansion, might also accelerate the reduction of the genetic variation in landrace populations. Interestingly, populations from Longmen Mountain (LMM) and Daliangshan Mountain (DLSM) exhibited relatively higher levels of genetic diversity, inferring the two historical genetic diversity centers of the species. Moreover, moderate population subdivision was also detected by both chloroplast DNA (GST = 0.215; NST = 0.256) and nuclear DNA (GST = 0.146; NST = 0.342), respectively. We inferred that the episodes of efficient gene flow through seed dispersal, together with features of long generation cycle and inbreeding mating system, were likely the main contributors causing the observed phylogeographic patterns. Finally, factors that led to the present demographic patterns of populations from these regions and taxonomic varieties were also discussed. PMID:25521479

    We investigated relationships between the flowering phenology of Prunus yedoensis "Somei-yoshino" (cherry blossom) and the local temperatures in Japan. Our observations were carried out across the Okayama Plain, which included Okayama City (about 700,000 inhabitants), from the winter of 2008 to the spring of 2009. Local air temperature (AT) and the globe temperature (GT) were recorded at the tree height. The flowering dates (FDs) of P. yedoensis were earliest in the central commercial area (located at the center of the plain), followed by the north residential area (further inland), and finally the south residential area (seaward). The recorded FDs were related to the period-averaged daily maximum/minimum AT and GT, and the phenologically effective AT and GT defined in this study. Of these parameters, the phenologically effective GTs correlated most with the FDs. Since the GT is determined by AT, solar and infrared radiations, and wind speed, our previous result suggests that a combination of these three components surrounding the tree is more important for budding and flowering than is AT alone. The supposition is supported by the flowering of P. yedoensis being the latest at the coastal region of the Okayama Plain where the AT were higher than at the inland region, excluding the urban area; it is probably caused by stronger winds there than at the other sites.

  12. Genetic variability of wild cherry (Prunus avium L. seed stands in Slovenia as revealed by nuclear microsatellite loci.

    Full Text Available Microsatellite markers were used to describe the genetic variability of four seed stands of wild cherry (Prunus avium L.. One hundred and thirty one individuals were genotyped at ten nuclear microsatellite loci. Total genetic diversity was high (H(E = 0.704, while differences between stands were small but significant (F(ST = 0.053, G'(ST = 0.234. There was a significant amount of clonal reproduction in one stand, with only 11 genotypes identified among 36 trees. One stand showed a significant excess (F(IS = -0.044 of heterozygosity, and one showed a deficit (F(IS = 0.044. Our results demonstrate the importance of taking into account the biological and genetic characteristics of species in forest management, especially when determining a new seed stand. The small genetic differences found between seed stands indicate that a large number of stands are not required. However, they should be carefully selected and should possess adequate genetic variability to ensure low relatedness between seed trees.

    Anthocyanins from tart cherries, Prunus cerasus L. (Rosaceae) cv. Balaton and Montmorency; sweet cherries, Prunus avium L. (Rosaceae); bilberries, Vaccinum myrtillus L. (Ericaceae); blackberries, Rubus sp. (Rosaceae); blueberries var. Jersey, Vaccinium corymbosum L. (Ericaceae); cranberries var. Early Black, Vaccinium macrocarpon Ait. (Ericaceae); elderberries, Sambucus canadensis (Caprifoliaceae); raspberries, Rubus idaeus (Rosaceae); and strawberries var. Honeoye, Fragaria x ananassa Duch. (Rosaceae), were investigated for cyclooxygenase inhibitory and antioxidant activities. The presence and levels of cyanidin-3-glucosylrutinoside 1 and cyanidin-3-rutinoside 2 were determined in the fruits using HPLC. The antioxidant activity of anthocyanins from cherries was comparable to the commercial antioxidants, tert-butylhydroquinone, butylated hydroxytoluene and butylated hydroxyanisole, and superior to vitamin E, at a test concentration of 125 microg/ml. Anthocyanins from raspberries and sweet cherries demonstrated 45% and 47% cyclooxygenase-I and cyclooxygenase-II inhibitory activities, respectively, when assayed at 125 microg/ml. The cyclooxygenase inhibitory activities of anthocyanins from these fruits were comparable to those of ibuprofen and naproxen at 10 microM concentrations. Anthocyanins 1 and 2 are present in both cherries and raspberry. The yields of pure anthocyanins 1 and 2 in 100 g Balaton and Montmorency tart cherries, sweet cherries and raspberries were 21, 16.5; 11, 5; 4.95, 21; and 4.65, 13.5 mg, respectively. Fresh blackberries and strawberries contained only anthocyanin 2 in yields of 24 and 22.5 mg/100 g, respectively. Anthocyanins 1 and 2 were not found in bilberries, blueberries, cranberries or elderberries. PMID:11695879

    This paper reports the occurrence of both free and glycosidically bound aroma compounds in three sweet cherry cultivars ('Hongdeng', 'Hongyan' and 'Rainier'), with 97 compounds being identified in the three cultivars. The major free volatile compounds found were hexanal, (E)-2-hexenal, (E)-2-hexen-1-ol, benzyl alcohol and benzaldehyde. The major bound volatile compounds found were benzyl alcohol, geraniol, 2-phenylethanol. Also 4-vinylphenol was found in cherry fruit for the first time, and has a relatively high concentration of the glycosidically-bound form in 'Rainier'. Odour activity values (OAVs) were determined for both free and bound volatiles, with 18 compounds having an OAV above 1. The highest OAVs for three cultivars were (E)-β-ionone, hexanal, decanal and (E)-2-hexenal with the highest being over 800 for (E)-β-ionone in 'Honyang'. From these results, it was concluded that the aroma compounds present were similar in all three cultivars, but there was significant variation found in their levels and hence contribution to the aroma of these cultivars.

    The cherry was treated with ultrasonic waves (33 kHz, 60 W) at different time intervals (10, 20, 30, 40, 60 min) and study was carried out to analyze the change in physico-chemical properties (TSS, pH, color, acidity and firmness), antioxidant potential and microbial load of the fruit during the storage period of 15 days at 4 °C. It was observed that ultrasound treatment (US) between 30 and 40 min showed better retention of color of the fruit during the storage period. The antioxidant assays (DPPH, ABTS and TPC) also increased significantly (P ≤ 0.05) up to 40 min, however the firmness of the fruit was affected and it showed a significant decrease beyond 20 min of US treatment. The sample with 40 min US treatment showed significantly less microbial load than other samples. The 20-40 min US treatment time (33 kHz, 60 W) was suggested for preservation of cherry during the storage at 4 °C. PMID:27478231

    High-throughput genome scans are important tools for genetic studies and breeding applications.

This effort was led by RosBREED, a community initiative to enable marker-assisted breeding for rosaceous crops. Next-generation sequencing in diverse breeding germplasm provided 25 billion basepairs (Gb) of cherry DNA sequence from which were identified genome-wide SNPs for sweet cherry and for the two sour cherry subgenomes derived from sweet cherry (avium subgenome) and P. fruticosa (fruticosa subgenome). Anchoring to the peach genome sequence, recently released by the International Peach Genome Initiative, predicted relative physical locations of the 1.9 million putative SNPs detected, preliminarily filtered to 368,943 SNPs. Further filtering was guided by results of a 144-SNP subset examined with the Illumina GoldenGate® assay on 160 accessions. A 6K Infinium® II array was designed with SNPs evenly spaced genetically across the sweet and sour cherry genomes. SNPs were developed for each sour cherry subgenome by using minor allele frequency in the sour cherry detection panel to enrich for subgenome-specific SNPs followed by targeting to either subgenome according to alleles observed in sweet cherry. The array was evaluated using panels of sweet (n = 269) and sour (n = 330) cherry breeding germplasm. Approximately one third of array SNPs were informative for each crop. A total of 1825 polymorphic SNPs were verified in sweet cherry, 13% of these originally developed for sour cherry.

Among the researched sour cherries, ‘Oblacinska’ cultivar contained the highest amounts of all groups of phenolics, followed by ‘Cigancica’ > ‘Marela’. A significant difference were observed in the phenolic content among different cultivars and growing seasons (p<0.05, and the phenolic compounds were significantly higher in the growing season 2009. The examined cultivars possess a high antioxidant capacity, and all phenolics of highy correlation with TAC. The following compounds were identified and quantified using HPLC-DAD: 4 anthocyanins, the most abundant of which was cyaniding-3-glucoside in ‘Marela’ and ‘Oblacinska’, and cyanidin-3-glucosylrutinoside in ‘Cigancica’, and 4 hydroxycinnamic acids, the most abundant of which was neochlorogenic acid in all sour cherry cultivars. The growing and ripening process on the tree of sour cherry cv. Oblacinska was evaluated, also. The results showed significant increases in total phenols during the ripening, the total anthocyanins and total antioxidant capacity and 4 quantified anthocyanins, however the neochlorogenic acid decreased during the ripening. The study indicated that the growing and climate conditions in southeast Serbia are convenient for introducing sour cherry cultivars.

    Cherry (Prunus Cerasus) is still one of the most popular preserve in Turkish cuisine. Cherry has been traditionally used for the treatment of inflammatory-related symptoms. Recent researches have proved that cherry is a valuable natural source of some important bioactive compounds in human health preservation. Evidence suggests that, cherry consumption may decrease the risk of chronic diseases and cancer. The aim of the present study was to determine the effects of cherry on breast cancer cells lines, asymmetric dimethylarginine (ADMA) level and certain multidrug-resistant bacteria. The cancer cell proliferation activity and analysis of apoptotic-necrotic cells was evaluated by using the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) and scoring of apoptotic cell nuclei. Measurement of ADMA and the minimum inhibitory concentration was accomplished by HPLC and the micro dilution broth method. The results showed that, extracts of cherry exhibit anti-proliferative activity in mammary adenocarcinoma (MCF-7) & mouse mammary tumor cell (4T1) breast cancer cells lines as well as induction of apoptosis, lower ADMA concentrations in cell cultures treated with cherry extract and antibacterial effects against certain multidrug-resistant bacteria in vitro. These findings may open new horizons for traditional anti-inflammatory product as prophylactic-therapeutic agent from cancer, cardiovascular diseases and multidrug-resistant infections.

    Full Text Available Prunus azorica (Hort. ex Mouillef. Rivas Mart., Lousã, Fern. Prieto, E. Dias, J.C. Costa &C. Aguiar is an endangered tree endemic to the Azores, with an ecological and ornamentalinterest. The objective of this study was to determine the conditions necessary for thesuccessful propagation of P. azorica by stem cuttings and air-layering. Stem cuttingscollected in March with two apical leaf pairs pruned to 1/3 of their leaf area were submittedto different treatments, including a basal split wound, two rooting mixtures, namely, perlite and peat (1:1 or perlite and natural soil (1:1, and dipping of the base in indole-3-butyric acid (IBA solution at four concentrations (0, 2500, 5000 or 7000 mg/L. After eight weeks 75% rooting was achieved with 75 to 88% survival, without addition of IBA and with split wound using both substrate mixtures. Air layering was conducted in June in branches of adult trees with the addition of 0, 2500 or 3000 mg/L of IBA. After 12 months 100%rooting and survival was recorded in all treatments. Our study thus indicates that P. azorica is a taxon amenable for vegetative propagation by stem cuttings and air layering withoutrequiring addition of IBA to induce rooting. Both methods should be used in order to recover natural populations, when seeds are not available or are available in reduced amounts.

    Gametophytic self-incompatibility (GSI) is an outcrossing mechanism in flowering plants that is genetically controlled by 2 separate genes located at the highly polymorphic S-locus, termed S-haplotype. This study characterizes a pollen part mutant of the S(1)-haplotype present in sour cherry (Rosaceae, Prunus cerasus L.) that contributes to the loss of GSI. Inheritance of S-haplotypes from reciprocal interspecific crosses between the self-compatible sour cherry cultivar Ujfehértói Fürtös carrying the mutated S(1)-haplotype (S(1)'S(4)S(d)S(null)) and the self-incompatible sweet cherry (Prunus avium L.) cultivars carrying the wild-type S(1)-haplotype revealed that the mutated S(1)-haplotype confers unilateral incompatibility with a functional pistil component and a nonfunctional pollen component. The altered sour cherry S(1)-haplotype pollen part mutant, termed S(1)', contains a 615-bp Ds-like element within the S(1)-haplotype-specific F-box protein gene (SFB(1)'). This insertion generates a premature in-frame stop codon that would result in a putative truncated SFB(1) containing only 75 of the 375 amino acids present in the wild-type SFB(1). S(1)' along with 2 other previously characterized Prunus S-haplotype mutants, S(f) and S(6m), illustrate that mobile element insertion is an evolutionary force contributing to the breakdown of GSI.

    Experiments were conducted using gamma radiation to determine radiosensitivities of main and accessory buds, to increase the proportion of mutant tissue, and to determine the type of damage and mode of recovery in irradiated shoot spices of sweet cherry cvs Napoleon and Bin. Survival, growth, and the types of mutations of V/sub 1/ (primary) shoots and V/sub 2/ plants were observed. LD/sub 50/ values, based on survival of forced buds were about 5kR for both acute and fractionated irradiation in air, 5.5kR for acute exposure in water, and 6kR for fractionated dose in water. 0.39-0.69 accessory buds/site on non-irradiated Napoleon had forced after 30 days in the glasshouse. In the Bing field experiment with main buds, the LD/sub 50/ for both acute and fractionated irradiation in air was 3.5kR. In water, the LD/sub 50/ was 5kR for acute treatment and 6.5kR for fractionated dose. The overall mutation frequency in Napoleon V/sub 2/ shoots derived from main buds was 7.6%: 0.04% growth-reduced mutants, 0.4% total leaf mutants, and7.1% partial leaf mutants.

    Full Text Available The paper presents results of a three-year study of self-(incompatibility in four economically important sweet cherry genotypes - ‘Karina’, ‘Kordia’, ‘Regina’ and ‘Summit’, under agro-environmental conditions of Western Serbia. Determination of S-RNase genotype, microscopic observation of the pollen tube growth rate and assaying of the fruit set level after self-pollination were used to assess the genotypes. ‘Kordia’ (S3S6, ‘Regina’ (S1S3 and ‘Summit’ (S1S2 are self-incompatible genotypes, with a considerable number of pollen tubes ending the growth in the middle third of the style and lack of fruit set. ‘Karina’, as S3S4 genotype, behaved as self-compatible, since its pollen tubes reached the base of the style and ovary, penetrating the nucellus. In addition, fruit set for ‘Karina’ was recorded in all three years of study (40.26%, 18.79% and 21.81%, respectively. [Projekat Ministarstva nauke Republike Srbije, br.

    The MYB transcription factors and plant hormone ABA have been suggested to play a role in fruit anthocyanin biosynthesis, but supporting genetic evidence has been lacking in sweet cherry. The present study describes the first functional characterization of an R2R3-MYB transcription factor, PacMYBA, from red-colored sweet cherry cv. Hong Deng (Prunus avium L.). Transient promoter assays demonstrated that PacMYBA physically interacted with several anthocyanin-related basic helix-loop-helix (bHLH) transcription factors to activate the promoters of PacDFR, PacANS and PacUFGT, which are thought to be involved in anthocyanin biosynthesis. Furthermore, the immature seeds of transgenic Arabidopsis plants overexpressing PacMYBA exhibited ectopic pigmentation. Silencing of PacMYBA, using a Tobacco rattle virus (TRV)-induced gene silencing technique, resulted in sweet cherry fruit that lacked red pigment. ABA treatment significantly induced anthocyanin accumulation, while treatment with the ABA biosynthesis inhibitor nordihydroguaiaretic acid (NDGA) blocked anthocyanin production. PacMYBA expression peaked after 2 h of pre-incubation in ABA and was 15.2-fold higher than that of sweet cherries treated with NDGA. The colorless phenotype was also observed in the fruits silenced in PacNCED1, which encodes a key enzyme in the ABA biosynthesis pathway. The endogenous ABA content as well as the transcript levels of six structural genes and PacMYBA in PacNCED1-RNAi (RNA interference) fruit were significantly lower than in the TRV vector control fruit. These results suggest that PacMYBA plays an important role in ABA-regulated anthocyanin biosynthesis and ABA is a signal molecule that promotes red-colored sweet cherry fruit accumulating anthocyanin.

    Lipophilic bioactive compounds in oils recovered from the kernels of seven sweet cherry (Prunus avium L.) cultivars, harvested at single location in 2013, were studied. Oil yield in sweet cherry ranged between 30.3-40.3 % (w/w) dw. The main fatty acids were oleic acid (39.62-49.92 %), linoleic acid (31.13-38.81 %), α-eleostearic acid (7.23-10.73 %) and palmitic acid (5.59-7.10 %), all four represented approximately 95 % of the total detected fatty acids. The ranges of total tocochromanols and sterols were between 83.1-111.1 and 233.6-419.4 mg/100 g of oil, respectively. Regardless of the cultivar, the γ-tocopherol and β-sitosterol were the main lipophilic minor bioactive compounds. The content of the carotenoids and squalene were between 0.38-0.62 and 60.9-127.7 mg/100 g of oil, respectively. Three significant correlations were found between oil yield and total contents of sterols (r = -0.852), tocochromanols (r = -0.880) and carotenoids (r = -0.698) in sweet cherry kernel oils. The oil yield, as well as the content of lipophilic bioactive compounds in oil was significantly affected by the cultivar. PMID:26984340

    A new spectrometric method ultra performance liquid chromatography-tandem mass spectrometric with high precision and rapid analysis was developed to separate 17 phenolic compounds. Different species of cherries, including 10 sweet cherry (Prunus avium L.) cultivars, a tart cherry (P. cerasus L.) rootstock (CAB), and a hybrid rootstock 'Colt' (P. avium × P. pseudocerasus), were analyzed for phenolics contents by this method. The results showed that significant differences were observed among the phenolic compound contents in different cherry species. In 10 sweet cherry cultivars, the contents of neochlorogenic acid and cyanidin-3O-rutinoside were much higher in red-colored fruits (for example, 64.60 and 44.50 mg/100 g fresh weight in Burlat, respectively) than those in bicolored ones. Principal component analysis revealed that cyanidin-3O-rutinoside was an effective index for grouping the cultivars with similar species and fruit colors. Moreover, there were strong positive correlations between phenolics content and antioxidant activity, which was higher in red-colored cherries. PMID:22417346

    Results described here span a total of three field seasons and quantitatively depict the effects of an economically important fungal pathogen (Blumeriella jaapii) on tart cherry (Prunus cerasus 'Montmorency') leaf physiology. For the first time, leaf photosynthesis, stomatal conductance (g(s)), maximum ribulose-1,5-bisphosphate carboxylation rate (V(cmax)), and maximum electron transport (J(max)) were measured as functions of visible cherry leaf spot disease (CLS) severity. Defined as the proportion of chlorotic and necrotic tissue per leaf, CLS severity was estimated from leaves of mature 'Montmorency' trees in 2007, 2008, and 2009. Briefly, as visible disease severity increased, all of the leaf-level physiological parameters decreased significantly (P < 0.01) and disproportionately. Thus, the effects of visible symptoms on leaf photosynthetic metabolic function encroached upon asymptomatic tissue as well. Impairment of photosynthetic metabolism in 'Montmorency' tart cherry leaves due to CLS appears to be mediated through disproportionately large perturbations in g(s), V(cmax), and J(max). These findings offer a new perspective on the amount of damage that this serious disease can inflict. PMID:22667445

    Full Text Available Fruit color is one of the most important economic traits of the sweet cherry (Prunus avium L.. The red coloration of sweet cherry fruit is mainly attributed to anthocyanins. However, limited information is available regarding the molecular mechanisms underlying anthocyanin biosynthesis and its regulation in sweet cherry.In this study, a reference transcriptome of P. avium L. was sequenced and annotated to identify the transcriptional determinants of fruit color. Normalized cDNA libraries from red and yellow fruits were sequenced using the next-generation Illumina/Solexa sequencing platform and de novo assembly. Over 66 million high-quality reads were assembled into 43,128 unigenes using a combined assembly strategy. Then a total of 22,452 unigenes were compared to public databases using homology searches, and 20,095 of these unigenes were annotated in the Nr protein database. Furthermore, transcriptome differences between the four stages of fruit ripening were analyzed using Illumina digital gene expression (DGE profiling. Biological pathway analysis revealed that 72 unigenes were involved in anthocyanin biosynthesis. The expression patterns of unigenes encoding phenylalanine ammonia-lyase (PAL, 4-coumarate-CoA ligase (4CL, chalcone synthase (CHS, chalcone isomerase (CHI, flavanone 3-hydroxylase (F3H, flavanone 3'-hydroxylase (F3'H, dihydroflavonol 4-reductase (DFR, anthocyanidin synthase (ANS and UDP glucose: flavonol 3-O-glucosyltransferase (UFGT during fruit ripening differed between red and yellow fruit. In addition, we identified some transcription factor families (such as MYB, bHLH and WD40 that may control anthocyanin biosynthesis. We confirmed the altered expression levels of eighteen unigenes that encode anthocyanin biosynthetic enzymes and transcription factors using quantitative real-time PCR (qRT-PCR.The obtained sweet cherry transcriptome and DGE profiling data provide comprehensive gene expression information that lends insights

    Using four different chromatographic steps, β-galactosidase was purified from the ripe fruit of sweet cherry to apparent electrophoretic homogeneity with approximately 131-fold purification. The Prunus avium β-galactosidase showed an apparent molecular mass of about 100 kDa and consisted of four different active polypeptides with pIs of about 7.9, 7.4, 6.9 and 6.4 as estimated by native IEF and β-galactosidase-activity staining. The active polypeptides were individually excised from the gel and subjected to SDS-PAGE. Each of the four native enzymes showing β-galactosidase activity was composed of two polypeptides with an estimated mass of 54 and 33 kDa. Both of these polypeptides were subjected to N-terminal amino acid sequence analysis. The 54 kDa polypeptide of sweet cherry β-galactosidase showed a 43% identity with the 44 kDa subunit of persimmon and apple β-galactosidases and the 48 kDa subunit of carambola galactosidase I. The sweet cherry β-galactosidase exhibited a strict specificity towards p-nitrophenyl β-D-galactopyranoside, a pH optimum of 4.0 and K(m) and V(max) values of 0.42 mM and 4.12 mmol min(-1) mg(-1) of protein respectively with this substrate. The enzyme was also active towards complex glycans. Taken together the results of this study prompted a role for this class of enzymes on sweet cherry fruit ripening and softening. PMID:23121861

    A homologue of SQUAMOSA/APETALA1, designated PaAP1, was isolated from Prunus avium by reverse transcription-PCR (RT-PCR). The full length of PaAP1 cDNA is 753 bp, and it codes for a polypeptide of 250 amino acid residues. Sequence comparison revealed that PaAP1 belongs to the MADS-box gene family. Phylogenetic analysis indicated that PaAP1 shared the highest identity with SQUA/AP1 homologues from Prunus serrulata. Real-time fluorescence quantitative PCR analysis showed that PaAP1 was expressed at high levels in petal, sepal, style, and flower buds, which was slightly different from the expression pattern of AP1 of Arabidopsis thaliana. To characterize the functions of PaAP1, we assessed Arabidopsis transformed with 35S::PaAP1. A total of 8 transgenic T(1) lines with an early flowering phenotype were obtained, and a 3:1 segregation ratio of flowering time was observed in the T(2) generation of 4 lines. This study provides the first functional analysis of an SQUA/AP1 homolog from P. avium and suggests that PaAP1 is potentially useful for shortening the juvenile period in sweet cherry. PMID:23206932

  1. Effects of planting density and bearing-branch composition on the yield of sweet cherry [Prunus avium] grown by hedge-row training

    International Nuclear Information System (INIS)

    To improve the yield of sweet cherries (Prunus avium L.) grown by hedge-row training, the following two methods were compared: increased numbers of spurs and bouquet spurs to improve the spur composition and narrowed row intervals to increase planting density. To develop spurs and bouquet spurs, 30 cm long branches were positioned at 30 cm intervals on lateral branches in addition to the conventional spur development from 5 cm current shoots. Although this measure decreased the number of bouquet spurs, it increased the total number of spurs including the conventional short spurs to improve the yield to 1,024 kg/10a from 557 kg/10a using conventional hedge-row training. However, this method decreased solar radiation in the tree crowns thereby lowering fruit quality. In contrast, increasing planting density from 3-m intervals to 2- or 1.5-m intervals did not affect fruit quality. Moreover, in contrast to a yield of 588 kg/10a when row intervals were 3 m, the row intervals narrowed to 2 m and 1.5 m improved the yield to 881 kg/10a and 1,101 kg/10a, respectively. The above results show that decreasing row intervals is an effective method for increasing the yield of sweet cherries grown by hedge-row training without lowering fruit quality

    The exocarp, or skin, of fleshy fruit is a specialized tissue that protects the fruit, attracts seed dispersing fruit eaters, and has large economical relevance for fruit quality. Development of the exocarp involves regulated activities of many genes. This research analyzed global gene expression in the exocarp of developing sweet cherry (Prunus avium L., 'Regina'), a fruit crop species with little public genomic resources. A catalog of transcript models (contigs) representing expressed genes was constructed from de novo assembled short complementary DNA (cDNA) sequences generated from developing fruit between flowering and maturity at 14 time points. Expression levels in each sample were estimated for 34 695 contigs from numbers of reads mapping to each contig. Contigs were annotated functionally based on BLAST, gene ontology and InterProScan analyses. Coregulated genes were detected using partitional clustering of expression patterns. The results are discussed with emphasis on genes putatively involved in cuticle deposition, cell wall metabolism and sugar transport. The high temporal resolution of the expression patterns presented here reveals finely tuned developmental specialization of individual members of gene families. Moreover, the de novo assembled sweet cherry fruit transcriptome with 7760 full-length protein coding sequences and over 20 000 other, annotated cDNA sequences together with their developmental expression patterns is expected to accelerate molecular research on this important tree fruit crop.

    The paper reports the phenolic, anthocyanin, and volatile compounds and sensory characteristics of 12 cultivars of sweet cherries including cvs. Belge, Bing, Dalbasti, Durona di Cesena, Lambert, Merton Late, Starks Gold, Summit, Sweetheart, Van, Vista, and 0-900 Ziraat. Eight individual phenolic compounds were determined by the HPLC-DAD method. Among these cherries, cvs. Bing, Durona di Cesena, and Lambert contained higher levels of total individual phenolic compounds than the other cultivars. Six anthocyanins were detected in cherries and cyanidin-3-O-rutinoside was principal and it was the highest level in cv. Bing. The major volatiles found were 1-hexanol, (E)-2-hexen-1-ol, benzylalcohol, hexenal, (E)-2-hexenal, and benzaldehyde. Sensory evaluation of the cherries showed that cvs. Belge, Bing, Dalbasti, and Summit have higher textural and flavor scores than others. It was concluded that the same compounds for phenolic or volatiles profiles of sweet cherries were similar in qualitative; however, quantitative differences were observed in these cultivars.

    The acyclic polyol sorbitol is a primary photosynthetic product and the principal photosynthetic transport substance in many economically important members of the family Rosaceace (e.g. almond [Prunus dulcis (P. Mill.) D.A. Webber], apple [Malus pumila P. Mill.], cherry [Prunus spp.], peach [Prunus persica L. Batsch], and pear [Pyrus communis]). To understand key steps in long-distance transport and particularly partitioning and accumulation of sorbitol in sink tissues, we have cloned two sorbitol transporter genes (PcSOT1 and PcSOT2) from sour cherry (Prunus cerasus) fruit tissues that accumulate large quantities of sorbitol. Sorbitol uptake activities and other characteristics were measured by heterologous expression of PcSOT1 and PcSOT2 in yeast (Saccharomyces cerevisiae). Both genes encode proton-dependent, sorbitol-specific transporters with similar affinities (K(m) sorbitol of 0.81 mM for PcSOT1 and 0.64 mM for PcSOT2). Analyses of gene expression of these transporters, however, suggest different roles during leaf and fruit development. PcSOT1 is expressed throughout fruit development, but especially when growth and sorbitol accumulation rates are highest. In leaves, PcSOT1 expression is highest in young, expanding tissues, but substantially less in mature leaves. In contrast, PcSOT2 is mainly expressed only early in fruit development and not in leaves. Compositional analyses suggest that transport mediated by PcSOT1 and PcSOT2 plays a major role in sorbitol and dry matter accumulation in sour cherry fruits. Presence of these transporters and the high fruit sorbitol concentrations suggest that there is an apoplastic step during phloem unloading and accumulation in these sink tissues. Expression of PcSOT1 in young leaves before completion of the transition from sink to source is further evidence for a role in determining sink activity. PMID:12692316

    Excessive softening is a major cause of postharvest deterioration during transportation and storage of fresh cherries. In continuing our studies to identify the factors determining the textural differences between sweet cherry fruit genotypes, we evaluated the solubilization, depolymerization, and monosaccharide composition of pectin and hemicelluloses from five sweet cherry cultivars ('Chelan', 'Sumele', 'Brooks', 'Sunburst', and 'Regina') with contrasting firmness and cracking susceptibility at two developmental stages (immature and ripe). In contrast to what is usually shown in most fruits, cherry softening could occur is some cultivars without marked increases in water-soluble pectin. Although polyuronide and hemicellulose depolymerization was observed in the water-soluble and dilute-alkali-soluble fractions, only moderate association occurs between initial polymer size and cultivar firmness. In all the genotypes the Na2CO3-soluble polysaccharides (NSF) represented the most abundant and dynamic wall fraction during ripening. Firm cultivars showed upon ripening a lower neutral sugars/uronic acid ratio in the NSF, suggesting that they have a lower proportion of highly branched polyuronides. The similar molar ratios of arabinose plus galactose to rhamnose [(Ara+Gal)/Rha] suggest that the cultivars differed in their relative proportion of homogalacturonan (HG) and rhamnogalacturonan I (RG-I) rather than in the size of the RG side chains; with greater proportions of HG in firmer cherries. Ultraviolet matrix-assisted laser desorption/ionization time-of-flight mass spectrometry was useful to identify the depolymerization patterns of weakly bound pectins, but gave less accurate results on ionically bound pectins, and was unable to find any pattern on covalently bound pectins.

    Previously, we have meticulously examined the efficacy of the measurable antimicrobial activity of sweet cherry (Prunus avium) extracts on a wide spectrum of gram-positive and gram-negative bacteria, in addition to the fungus, Candida albicans, a priori. In order to further understand the biochemical constituents and antioxidant activities of a variety of extracts of sweet cherries, antioxidant compounds of immunological significance, including L-ascorbic acid (vitamin C), phenols, flavonoids, and anthocyanins, and the total antioxidant (free radical scavenging) activity were simultaneously measured under varying and versatile extraction conditions (mild heating [5, 10 and 20 min.], and brief microwave exposure [1, 2 and 5 min.]) for a variety of extracts: i) whole juice extracts (WJE), ii) methanol-extracted juice (MEJ), iii) ddH2O-extracted pomace (dPOM), and iv) methanol-extracted pomace (mPOM). The antioxidant activity under the versatile extraction conditions adopted in this study was conspicuously reduced, such that the % inhibition against 2,2- diphenyl-1-picrylhydrazyl (DPPH) followed an inverse, negative correlational trendline. Moreover, ascorbic acid content was not affected with mild to prolonged heating or microwave exposure, except tangibly with dPOM and mPOM. The total phenols content assessed showed no significant variations, as compared with control extracts. In a manner similar to ascorbic acid, total flavonoids were mildly reduced under varying conditions, an effect mimicked to a certain extent with anthocyanins. Assessment of extraction means as compared with WJE revealed sharp decrease in the antioxidant activity for dPOM and mPOM, significant increase in L-ascorbic acid, total phenol, and flavonoid contents for MEJ, dPOM, and mPOM, and mild decrease in anthocyanin contents for dPOM and mPOM. These results confirm the measurable antioxidant activities and contents of P. avium extracts under versatile conditions of mild exposure, an effect

    European bird cherry (Prunus padus) (EBC) is an invasive ornamental tree that is spreading rapidly in riparian forests of urban Alaska. To determine how the spread of EBC affects leaf litter processing by aquatic invertebrate shredders, we conducted complementary leaf pack experiments in two streams located in Anchorage, Alaska. The first experiment contrasted invasive EBC with three native tree species—thin-leaf alder (Alnus tenuifolia), paper birch (Betula neoalaskana), and black cottonwood (Populus trichocarpa)—in one reach of Chester Creek; finding that EBC leaf litter broke down significantly faster than birch and cottonwood, but at a similar rate to alder. The second experiment contrasted EBC with alder in four reaches of Campbell and Chester creeks; finding that while EBC leaf litter broke down significantly faster than alder in Chester Creek, EBC broke down at a similar rate to alder in Campbell Creek. Although EBC sometimes supported fewer shredders by both count and mass, shredder communities did not differ significantly between EBC and native plants. Collectively, these data suggest that invasive EBC is not currently exhibiting strong negative impacts on leaf litter processing in these streams, but could if it continues to spread and further displaces native species over time.

Fruit height, width, thickness and weight were measured. Width, thickness and weight of control fruit were the smallest.Fruit from 3,5,6-TPA - treated trees did not show significant difference in comparison to control. However, fruit from GA 3 – treated trees had significantly improved all characteristics in comparison to control fruits. Weight of fruit from trees treated with combination of 3,5,6-TPA and GA 3 was 14% higher than control fruit and 2.8% higher than fruit from GA 3 - treated trees, but there was no significant difference comparing to fruit from trees treated with GA 3 alone. These results are preliminary results after a one-year study and more research should be done to examine the possible influence of other factors, such as ecological factors, before final management recommendations could be made.

    Full Text Available The objective of this study was to investigate changes in photosynthetic efficiency applying repeated measures ANOVA using the photosynthetic performance index (PIABS of the JIP-test as a vitality parameter in seven genotypes of sour cherry (Prunus cerasus, L. during 10 days of continuous water deficit. Both univariate and multivariate ANOVA repeated measures revealed highly significant time effect (Days and its subsequent interactions with genotype and water deficit. However, the multivariate Pillai’s trace test detected the interaction Time × Genotype × Water deficit as not significant. According to the Tukey’s Studentized Range (HSD test, differences between the control and genotypes exposed to water stress became significant on the fourth day of the experiment, indicating that the plants on the average, began to lose their photosynthetic efficiency four days after being exposed to water shortage. It corroborates previous findings in other species that PIABS is very sensitive tool for detecting drought stress.

    Full Text Available The paper presents a protocol for micropropagation of Prunus sp. rootstocks included in the sweet and sour cherry breeding program. Germplasm diversity for rootstock breeding derives from natural populations, where conditions and biological vectors for systematic infection with viral diseases are constantly present. The establishment of aseptic culture depends primarily on the explant type, as all selections were collected from natural habitat. For nearly all investigated selections, dormant buds were the favored source, due to enabling rosette initiation in more than 58% cases. In P. cerasus L. selections, 100% contamination was noted when shoot tips were used as an explant source. Significant influence of the double-phase medium on the number and height of multiplied shoots was observed in the standard cherry rootstock, ‘Gisela 6’. For P. fruticosa Pall., selection ‘SV1’ and ‘SV2’, and P. cerasus ‘D6’ selection, the double-phase medium also had a significant effect on the height of multiplied shoots, when compared to solid DKW (Driver and Kuniyuki Walnut medium. Genetic variability of selections within the investigated species resulted in variable plant rooting success. Adding Fe-EDDHA (Ethylenediamine di-2-hydroxy-phenyl acetate ferric in the 200 mg l-1 concentration to the rooting medium significantly enhanced the percentage of rooted plants. The highest rooting percentage was noted for ‘Gisela 6’ and ‘D6’ genotype at 1 mg l-1 IBA (indole-3-butyric acid, while 0.8 mg l-1 was the optimum concentration for P. mahaleb L. ‘M1’ selection. P. fruticosa genotypes required significantly higher IBA concentration for rooting (2.5 and 3.5 mg l-1.

    Full Text Available Anthocyanins are essential contributors to fruit coloration, an important quality feature and a breed determining trait of a sweet cherry fruit. It is well established that the biosynthesis of anthocyanins is regulated by an interplay of specific transcription factors belonging to MYB and bHLH families accompanied by a WD40 protein. In this study, we isolated and analyzed PaWD40, PabHLH3, PabHLH33, and several closely related MYB10 gene variants from different cultivars of sweet cherry, analyzed their expression in fruits with different anthocyanin levels at several developmental stages, and determined their capabilities to modulate anthocyanin synthesis in leaves of two Nicotiana species. Our results indicate that transcription level of variant PaMYB10.1-1 correlates with fruit coloration, but anthocyanin synthesis in Nicotiana was induced by another variant, PaMYB10.1-3, which is moderately expressed in fruits. The analysis of two fruit-expressed bHLH genes revealed that PabHLH3 enhances MYB-induced anthocyanin synthesis, whereas PabHLH33 has strong inhibitory properties.

    Two sweet cherry cultivars ('New Star' and 'Sweet Heart') were chosen to explore the impact of passive modified atmosphere packaging on the eating quality and health-promoting properties of fruit. Packaged and unpackaged fruits were stored at 0 ℃ for 15 or 30 days, followed by zero or three days at 20 ℃, after which the analyses were undertaken. In most cases, modified atmosphere packaging helped preserving higher firmness values and reducing the incidence of alterations and decay in both cultivars, but the effects on other physicochemical attributes were different for each cultivar. Partial least squares regression procedures were used to reveal relationships among the different variables assessed. Generally, fruits displaying higher antioxidant capacity were also characterised by higher values for firmness and titratable acidity, in turn related to better acceptability scores in both cultivars. However, the attributes contributing most to acceptability were different in each case. In 'New Star' fruit, acceptability was closely related to the perception of cherry flavour. In this cultivar, acetaldehyde content was related to the perception of off-flavours, while ethanol content was found to associate to soluble solids and to the perception of sweetness. In contrast, acceptability of 'Sweet Heart' fruit was related mainly to the perception of firmness and, to a lower extent, of sweetness. PMID:24474188

    The transition from self-incompatibility (SI) to self-compatibility (SC) is regarded as one of the most prevalent transitions in Angiosperm evolution, having profound impacts on the genetic structure of populations. Yet, the identity and function of mutations that result in the breakdown of SI in nature are not well understood. This work provides the first detailed genetic description of the breakdown of S-RNase-mediated gametophytic self-incompatibility (GSI) in a polyploid species that exhibits genotype-dependent loss of SI. Genetic analyses of six natural sour cherry (Rosaceae, Prunus cerasus) selections identified seven independent, nonfunctional S-haplotypes with disrupted pistil component (stylar-S) and/or pollen component (pollen-S) function. A genetic model demonstrating that the breakdown of SI in sour cherry is due to the accumulation of a minimum of two nonfunctional S-haplotypes within a single individual is developed and validated. Our finding that sour cherry is SI when only one nonfunctional S-haplotype is present has significant evolutionary implications since nonfunctional S-haplotypes would be maintained in the population without causing an abrupt shift to SC. Furthermore, we demonstrate that heteroallelic sour cherry pollen is self-incompatible, which is counter to the well-documented phenomenon in the Solanaceae where SC accompanying polyploidization is frequently due to the SC of heteroallelic pollen.

    Strains of Lactobacillus plantarum, Pediococcus acidilactici, Pediococcus pentosaceus and Leuconostoc mesenteroides subsp. mesenteroides were identified from 8 cultivars of sweet cherry by partial 16S rRNA gene sequence and subjected to typing by Random Amplified Polymorphic DNA-Polymerase Chain Reaction (RAPD-PCR) analysis. Representative isolates from each species and each cultivar were screened based on the kinetics of growth on cherry puree added of (10%, v/v) stem infusion (CP-SI). A protocol for processing and storage of CP-SI, which included fermentation by selected autochthonous P. pentosaceus SWE5 and L. plantarum FP3 (started CP-SI) or spontaneous fermentation (unstarted CP-SI), was set up. Starters grew and remained viable at elevated cell numbers (ca. 9.0 log cfu g(-1)) during 60 days of storage at 4 °C. The number of presumptive lactic acid bacteria of the unstarted CP-SI did not exceed the value of ca. 3.0 log cfu g(-1). Consumption of carbohydrates (e.g., glucose and fructose) by starter lactic acid bacteria was limited as well as it was the lactic acid fermentation. Consumption of organic acids (e.g., malic acid) and free amino acids was evident, especially, throughout storage. Compared to CP-SI before processing, the concentrations of total phenolic compounds and anthocyanins did not vary in the started CP-SI. The concentration of anthocyanins slightly decreased in the unstarted CP-SI. The antioxidant activity, expressed as the scavenging activity toward DPPH radical, was found at highest level in the started CP-SI which approached that found in CP-SI before processing. During storage, viscosity and, especially, color indexes of started CP-SI were higher than those found in the unstarted CP-SI. Fermentation by autochthonous lactic acid bacteria seemed to also positively interfere with the sensory attributes of CP-SI. PMID:21569932

    Homomorphic self-incompatibility is a well-studied example of a physiological process that is thought to increase population diversity and reduce the expression of inbreeding depression. Whereas theoretical models predict the presence of a large number of S-haplotypes with equal frequencies at equilibrium, unequal allele frequencies have been repeatedly reported and attributed to sampling effects, population structure, demographic perturbation, sheltered deleterious mutations or selection pressure on linked genes. However, it is unclear to what extent unequal segregations are the results of gametophytic or sexual selection. Although these two forces are difficult to disentangle, testing S-alleles in the offspring of controlled crosses provides an opportunity to separate these two phenomena. In this work, segregation and transmission of S-alleles have been characterized in progenies of mixed donors and fully compatible pollinations under field conditions in Prunus avium. Seed set patterns and pollen performance have also been characterized. The results reveal paternal-specific distorted transmission of S-alleles in most of the crosses. Interestingly, S-allele segregation within any given paternal or maternal S-locus was random. Observations on pollen germination, pollen tube growth rate, pollen tube cohort size, seed set dynamics and transmission patterns strongly suggest post-pollination, prezygotic sexual selection, with male-male competition as the most likely mechanism. According to these results, post-pollination sexual selection takes precedence over frequency-dependent selection in explaining unequal S-haplotype frequencies. PMID:26559165

    The influence of thermal processing and nonenymatic as well as polyphenoloxidase-catalyzed browning reaction on the allergenicity of the major cherry allergen Pru av 1 was investigated. After thermal treatment of the recombinant protein rPru av 1 in the absence or presence of carbohydrates, SDS-PAGE, enzyme allergosorbent tests, and inhibition assays revealed that thermal treatment of rPru av 1 alone did not show any influence on the IgE-binding activity of the protein at least for 30 min, thus correlating well with the refolding of the allergen in buffer solution as demonstrated by CD spectroscopic experiments. Incubation of the protein with starch and maltose also showed no effect on IgE-binding activity, whereas reaction with glucose and ribose and, even more pronounced, with the carbohydrate breakdown products glyceraldehyde and glyoxal induced a strong decrease of the IgE-binding capacity of rPru av 1. In the second part of the study, the effect of polyphenoloxidase-catalyzed oxidation of polyphenols on food allergen activity was investigated. Incubation of rPru av 1 with epicatechin in the presence of tyrosinase led to a drastic decrease in IgE-binding activity of the protein. Variations of the phenolic compound revealed caffeic acid and epicatechin as the most active inhibitors of the IgE-binding activity of rPru av 1, followed by catechin and gallic acid, and, finally, by quercetin and rutin, showing significantly lower activity. On the basis of these data, reactive intermediates formed during thermal carbohydrate degradation as well as during enzymatic polyphenol oxidation are suggested as the active chemical species responsible for modifying nucleophilic amino acid side chains of proteins, thus inducing an irreversible change in the tertiary structure of the protein and resulting in a loss of conformational epitopes of the allergen.

    Three progenies of sour cherry (Prunus cerasus) were analysed to correlate self-(in)compatibility status with S-RNase phenotype in this allotetraploid hybrid of sweet and ground cherry. Self-(in)compatibility was assessed in the field and by monitoring pollen tube growth after selfing. The S-RNase phenotypes were determined by isoelectric focusing of stylar proteins and staining for RNase activity and, for the parents, confirmed by PCR. Seedling phenotypes were generally consistent with disomic segregation of S-RNase alleles. The genetic arrangements of the parents were deduced to be 'Köröser' (self-incompatible) S1S4.S(B) S(D), 'Schattenmorelle' (self-compatible) S6S13.S(B)S(B), and clone 43.87 (self-compatible) S4S13.S(B)S(B), where "." separates the two homologous genomes. The presence of S4 and S6 alleles at the same locus led to self-incompatibility, whereas S13 and S(B) at homologous loci led to self-compatibility. The failure of certain heteroallelic genotypes in the three crosses or in the self-incompatible seedlings indicates that S4 and S6 are dominant to S(B). However, the success of S13S(B) pollen on styles expressing corresponding S-RNases indicates competitive interaction or lack of pollen-S components. In general, the universal compatibility of S13S(B) pollen may explain the frequent occurrence of S13 and S(B) together in sour cherry cultivars. Alleles S(B) and S(D), that are presumed to derive from ground cherry, and S13, presumably from sweet cherry, were sequenced. Our findings contribute to an understanding of inheritance of self-(in)compatibility, facilitate screening of progenies for self-compatibility and provide a basis for studying molecular interactions in heteroallelic pollen.

    Prunus is an economically important genus well-known for cherries, plums, almonds, and peaches. The genus can be divided into three major groups based on inflorescence structure and ploidy levels: (1) the diploid solitary-flower group (subg. Prunus, Amygdalus and Emplectocladus); (2) the diploid corymbose group (subg. Cerasus); and (3) the polyploid racemose group (subg. Padus, subg. Laurocerasus, and the Maddenia group). The plastid phylogeny suggests three major clades within Prunus: Prunus-Amygdalus-Emplectocladus, Cerasus, and Laurocerasus-Padus-Maddenia, while nuclear ITS trees resolve Laurocerasus-Padus-Maddenia as a paraphyletic group.

    Iranian sour cherries (Prunus cerasus) were coated with fresh Aloe vera gel or treated with hot water (40 ± 2 °C) for 2 min and stored for 17 days at 4 ± 1 °C. The physicochemical characteristics of gel coated and hot water treated samples were compared with untreated fruit during the cold storage period. Untreated fruit showed increased respiration rate, rapid weight loss and colour change, accelerated aging and ripening. On the contrary, sour cherries, particularly those coated with gel significantly delayed the above mentioned parameters allowing a fruit storability extension. The sensory analysis in both treatments revealed beneficial effects in terms of delaying dehydration, maintenance of fruit visual aspect without any detrimental effect on taste, aroma or flavours. Consequently, Aloe vera gel coating and immersion in hot water maintained the properties during postharvest storage of sour cherries and could be introduced as two valuable, simple and non-contaminating treatments.

    The present report describes outcomes of animal studies conducted to determine the systemic and dermal toxicity of Prunus cerasus (sour cherry) seed kernel contents; and a separate evaluation of the photoprotective capacity of the kernel oil fraction. B6 mice and Hartley guinea-pigs were used for these experiments. Dosage groups of 6-8 animals were administered whole kernel meal in a dose range of 0-3000 mg/kg by gavage for 8 days, following which they were killed. The liver and kidney weights were recorded and histological examination performed on sections of these organs. Kidney function was assessed as blood urea nitrogen and creatinine and liver function by measurement of serum glutamic oxaloacetic transaminase, glutamic pyruvic transaminase and alkaline phosphatase. Dermal toxicity was evaluated in a Hartley guinea-pig model by comparing UVB-irradiated shaved skin to which the kernel oil had been applied with distilled water controls. In conclusion, no evidence of toxicity was observed to result from the consumption or dermal application of sour cherry seed kernel in the dose range at which it is likely to be used in foods or healthcare. Moreover, it was shown to have a powerful capacity to protect skin from UV damage. These results suggest it will prove to be a highly safe and effective addition to a wide range of products for general use. PMID:21751269

    Tart cherry, Prunus cerasus L. variety Montmorency, fruit were infested with plum curculio, Conotrachelus nenuphar (Herbst) (Coleoptera: Curculionidae), and treated with insecticides to target late instars, neonates, and eggs. The organophosphates azinphos-methyl and phosmet and the neonicotinoid thiamethoxam reduced larval emergence rates by >90% for all life stage targets; after >30 d, few surviving larvae were found inside fruit. Acetamiprid and thiacloprid also had curative activity and yielded >75% reductions in emergence and few surviving larvae in the fruit after >30 d. The juvenile hormone analog pyriproxyfen reduced larval emergence, but 66% of fruit that was treated to target late-instars still had live larvae inside of them after >30 d. Novaluron, chlorantraniliprole, and esfenvalerate had no curative activity. Indoxacarb had limited curative activity, and all targeted life stages had larval emergence. Internal and external residues were analyzed and are discussed in relation to their penetration and curative potential. The curative activity of azinphos-methyl has played an important role in meeting federal standards for infestation-free tart cherries at processing. Regulatory changes are eliminating the use of this compound, and new integrated pest management programs for plum curculio will need to address the loss of azinphos-methyl's curative activity.

    Full Text Available The objective of this work was to evaluate variability in reproductive biology traits and the correlation between them in genotypes of 'Oblačinska' sour cherry (Prunus cerasus. High genetic diversity was found in the 41 evaluated genotypes, and significant differences were observed among them for all studied traits: flowering time, pollen germination, number of fruiting branches, production of flower and fruit, number of flowers per bud, fruit set, and limb yield efficiency. The number of fruiting branches significantly influenced the number of flower and fruit, fruit set, and yield efficiency. In addition to number of fruiting branches, yield efficiency was positively correlated with fruit set and production of flower and fruit. Results from principal component analysis suggested a reduction of the reproductive biology factors affecting yield to four main characters: number and structure of fruiting branches, flowering time, and pollen germination. Knowledge of the reproductive biology of the 'Oblačinska' genotypes can be used to select the appropriate ones to be grown or used as parents in breeding programs. In this sense, genotypes II/2, III/9, III/13, and III/14 have very good flower production and satisfactory pollen germination.

    Chinese cherry (Cerasus pseudocerasus Lindl.) is one of the most economically domestic fruit trees in China. The rich variation of wild Chinese cherry is the most important breeding resource for existing cultivars. In order to reveal the levels and distribution of genetic variation within wild Chinese cherry of Sichuan Province, China, where is rich in wild Chinese cherry, the sequence variation of chloroplast DNA trnQ-rps16 intergenic spacer was analyzed in 145 individuals of all nine existing populations (seven from Sichuan, two from Shanxi and Guizhou provinces) of China. The results showed that trnQ-rps16 sequence were aligned with 13 polymorphic sites (1.87%), including 3 substitutions and 10 indels in 145 individuals, which revealed a low level of genetic diversity (h= 0.562,Π= 0.00184). Compared to other regions (h= 0.733, Π= 0.00243), a rather lower genetic diversity (h= 0.544,π= 0.00203) was found in the populations from Sichuan, and a large scale of genetic diversity among the seven populations was detected (h= 0-0.708; π= 0-0.00298), ranging from EM (h=0.000, Π=0.000) to TL (h=0.708, Π=0.00298). The low genetic diversity of populations may be strongly affected by founder effect and bottleneck effect because of the marginal nature, recent reduction, and consequent genetic drift of these populations. In addition, a fairly low genetic differentiation (FST= 0.21573) was found among the studied populations. This suggest that gene flow seems to originate from pronounced seed dispersal abilities of the species and it may play a significant role in shaping such a genetic structure. The long generation cycle of the species may also contribute to this structure. Based on these findings, a conservational plan for sampling or preserving fewer populations but more individuals from each population for the species was proposes.%中国樱桃(Cerasus pseudocerasus Lindl.)是我国古老的具有较高经济价值的栽培果树之一,个别性状突 出的野生

    Full Text Available To obtain high yields there should be high flower density and fruit set in sour cherry (Prunus cerasus L. production. Furthermore, in order to ensure successful fertilization, there should be satisfactory stigma receptivity, rapid pollen tube growth along the style, as well as adequate ovule longevity. This manuscript presents the study of the effective pollination period (EPP of four ‘Oblačinska’ sour cherry clones (II/2, III/9, XI/3 and XIII/1 that differs in pollen germination, fruit set and yields. In order to estimate EPP, pollination was conducted in six different stages of flower development: balloon stage, 2 d before anthesis (-2, at anthesis (0, and 2, 4, 6 and 8 d after anthеsis (DAA. The initial (IFS and final fruit set (FFS were recorded under the field conditions. Alongside with this, the rate of pollen tubes growth in the style was observed with fluorescent microscopy. The experimental design was completely randomized, a two-factorial analysis of variance was carried out and individual testing was performed using LSD test (p ≤ 0.05; p ≤ 0.01. The experiment was set in triplicates. Regarding FFS, clones II/2 and III/9 showed the best results (p ≤ 0.01 in 4 and 6 DAA. The number of pollen tubes in the style of the pistil decreased with subsequent terms of pollination, while its number in the ovule increased up to sixth day after pollination, followed by a decline. Clones II/2 and III/9 showed EPP which lasted from 6 to 8 d, while EPP found in clone XI/3, lasted only 2 d. It is concluded that only clone having long EPP should be used as parents for creating new sour cherry cultivars. [Projekat Ministarstva nauke Republike Srbije, br.

    Linkage maps are valuable tools in genetic and genomic studies. For sweet cherry, linkage maps have been constructed using mainly microsatellite markers (SSRs) and, recently, using single nucleotide polymorphism markers (SNPs) from a cherry 6K SNP array. Genotyping-by-sequencing (GBS), a new methodology based on high-throughput sequencing, holds great promise for identification of high number of SNPs and construction of high density linkage maps. In this study, GBS was used to identify SNPs from an intra-specific sweet cherry cross. A total of 8,476 high quality SNPs were selected for mapping. The physical position for each SNP was determined using the peach genome, Peach v1.0, as reference, and a homogeneous distribution of markers along the eight peach scaffolds was obtained. On average, 65.6% of the SNPs were present in genic regions and 49.8% were located in exonic regions. In addition to the SNPs, a group of SSRs was also used for construction of linkage maps. Parental and consensus high density maps were constructed by genotyping 166 siblings from a 'Rainier' x 'Rivedel' (Ra x Ri) cross. Using Ra x Ri population, 462, 489 and 985 markers were mapped into eight linkage groups in 'Rainier', 'Rivedel' and the Ra x Ri map, respectively, with 80% of mapped SNPs located in genic regions. Obtained maps spanned 549.5, 582.6 and 731.3 cM for 'Rainier', 'Rivedel' and consensus maps, respectively, with an average distance of 1.2 cM between adjacent markers for both 'Rainier' and 'Rivedel' maps and of 0.7 cM for Ra x Ri map. High synteny and co-linearity was observed between obtained maps and with Peach v1.0. These new high density linkage maps provide valuable information on the sweet cherry genome, and serve as the basis for identification of QTLs and genes relevant for the breeding of the species.

    are on more than 1 of these medications but, even with polypharmacy and optimal dosing, only 40%–60% of patients report partial relief of symptoms, and many have significant adverse effects, such as somnolence, constipation, and drug dependence. Objective Tart cherry juice has been shown to be effective in the treatment of some inflammatory conditions and has a very low incidence of adverse effects. The purpose of this study was to determine whether tart cherry juice is an effective treatment for neuropathic pain from nondiabetic peripheral polyneuropathies. Methods The study group consisted of 12 primary care patient volunteers with painful lower extremity peripheral neuropathy. Patients with diabetic peripheral neuropathy were excluded due to the potentially confounding effect of the increased glycemic load from cherry juice. All study patients had carried a diagnosis of peripheral neuropathy for 5–10 y. All patients described 9–10 out of 10 pain more than 50% of the time. All study patients had been on multiple antiepileptics, analgesics, and antidepressants for more than 2 y without significant improvement of symptoms. All study patients were allowed to remain on their prescribed doses of gabapentin, pregabalin, SNRIs, tricyclics, and SSRIs during the study. The patients agreed not to use NSAIDs, steroids, lidocaine, and narcotic pain relievers during the study. There were no restrictions on diet or activity. Presumed etiologies of the peripheral neuropathies in the study group were: 3 HIV, 2 chemotherapy-induced, 5 spinal disorders, and 2 idiopathic. All patients drank 4 oz of tart cherry juice 2 ×/d for 14 d. The juice used was a combination of Prunus cerasus, Prunus acida, Prunus avium, and Prunus fructicosa, imported from the Caucasus and sold commercially as “100% cherry juice from concentrate.” Results After 14 d of treatment, the patients were questioned regarding the level of their peripheral neuropathy pain.

    Several air pollutants in research and micropropagation laboratories originate from the combustion of hydrocarbons and their derivatives. The combustion products of some natural gases (propane-butane, propane, methane) and ethanol were analyzed, and the atmosphere composition was investigated inside the laminar flow box, inside the room where transplanting is performed and inside the culture vessels after transplanting. Large quantities of ethylene and other biologically active compounds are produced when hydrocarbons are partially oxidized or unevenly combusted and when ethanol is used for sterilization of dissecting instruments during transplanting operations. Air pollutants' effects have been tested on Prunus Colt shoot cultures; the toxicity symptoms observed suggest the elimination of gas combustion and alcohols during transplanting operations.

  5. Prunus transcription factors: Breeding perspectives

    Directory of Open Access Journals (Sweden)

    Valmor João Bianchi

    2015-06-01

    Full Text Available Many plant processes depend on differential gene expression, which is generally controlled by complex proteins called transcription factors (TFs. In peach, 1,533 TFs have been identified, accounting for about 5.5% of the 27,852 protein-coding genes. These TFs are the reference for the rest of the Prunus species. TF studies in Prunus have been performed on the gene expression analysis of different agronomic traits, including control of the flowering process, fruit quality, and biotic and abiotic stress resistance. These studies, using quantitative RT-PCR, have mainly been performed in peach, and to a lesser extent in other species, including almond, apricot, black cherry, Fuji cherry, Japanese apricot, plum, and sour and sweet cherry. Other tools have also been used in TF studies, including cDNA-AFLP, LC-ESI-MS, RNA and DNA blotting or mapping. More recently, new tools assayed include microarray and high-throughput DNA sequencing (DNA-Seq and RNA sequencing (RNA-Seq. New functional genomics opportunities include genome resequencing and the well-known synteny among Prunus genomes and transcriptomes. These new functional studies should be applied in breeding programs in the development of molecular markers. With the genome sequences available, some strategies that have been used in model systems (such as SNP genotyping assays and genotyping-by-sequencing may be applicable in the functional analysis of Prunus TFs as well. In addition, the knowledge of the gene functions and position in the peach reference genome of the TFs represents an additional advantage. These facts could greatly facilitate the isolation of genes via QTL (quantitative trait loci map-based cloning in the different Prunus species, following the association of these TFs with the identified QTLs using the peach reference genome.

    Climate change is affecting plant phenology worldwide. Phenological responses vary among species, but it is not clear how responses differ among closely related species. We examined a 25-yr record (1981-2005) of flowering times for 97 trees, representing 17 species and hybrids of cherry (Cerasus sp. or Prunus sp.) grown at Mt. Takao, in Tokyo, Japan. The cherry trees flowered earlier over time, by an average of 5.5 d over the 25-yr study. Earlier flowering was explained largely by a 1.8°C increase in February-March mean monthly temperatures. Most species and hybrids flowered 3-5 d earlier for each 1°C increase in temperature, but early-flowering taxa flowered as much as 9 d earlier for each 1°C increase in temperature. Flowering durations and differences in flowering times among species were greater in warm years than in cold years. Species and individual trees also flowered longer in warm years. These results show that the flowering times of closely related species may change similarly in response to climate change, but that early-flowering species may diverge from the overall trend in a predictable way.

    Dispersive liquid-liquid microextraction method (DLLME) combined with high-performance liquid chromatography-ultraviolet detection (HPLC-UV) was used to determine thiamine (B1), nicotinamide (B3) and pyridoxine (B6) in sour cherry juice. This method was rapid, simple and sensitive. Separation was accomplished using a C18 column. The optimum chromatographic conditions were found to be: mobile phase consisted of 8% methanol and 92% aqueous phase (1% (V/V) acetic acid water solution); flow rate, 0.7 mL/min; detection wavelength, 260 nm and pH, 3.3. The extraction efficiency of thiamine, nicotinamide and pyridoxine was influenced by factors such as: additional salt effect, the kind and volume of disperser and extraction solvents. In this research, the limit of detection (LOD) and quantification (LOQ) were 0.9 and 3 ng/mL for thiamine, 1.5 and 5 ng/mL for nicotinamide, 0.9 and 3 ng/mL for pyridoxine. The relative standard deviations (RSDs) were less than 2.87% (n=3). An appropriate linear behavior over the observed concentration range was obtained with the value of R²>0.996 for the target vitamins. This method was successfully applied to the sour cherry juice samples. Sour cherry var. Gise (Prunus cerasus var. Gise), which was used in this research, was a local variety of the sour cherry with large stone, double flowers, double fruits, dark red skin and dark red juice. This variety was identified in high altitude areas of Isfahan province after five years of study, since 2005, by Agricultural and Natural Resources Research Center of Isfahan. PMID:25587335

    Maddenia (Rosaceae) was long recognized as a distinct genus closely related to Prunus and was recently merged with the latter.The Maddenia clade of Prunus has been revised taxonomically with four species from eastern Asia recognized.Recent molecular studies have provided evidence that this group is nested within Prunus,having a close relationship with the Padus-Laurocerasus complex.To further test the phylogenetic position of Maddenia,this study investigates pollen morphology of all former Maddenia species and 28 other Prunus species,using scanning electron microscopy and light microscopy.The Prunus species sampled here represent major subgenera:Amygdalus,Cerasus,Laurocerasus,Padus,and Prunus s.s.We found that pollen grains of these groups are all monad and tricolporate with striate or rugulate sculpturing.The pollen evidence supports a close relationship between Maddenia and species of Padus and Laurocerasus subgroups (excluding the Pygeum group),all of which have elongated,thicker,and less directional muri.Pollen of the subgenera ofCerasus,Amygdalus,and Prunus has generally thinner,highly directional,and predominantly parallel muff.The pollen grains of the Pygeum subgroup are quite distinct from the other groups of Prunus.Pygeum pollen has rugulate exines with much shorter and rod-shaped muri.

    The impact of Montmorency tart cherry (Prunus cerasus L.) concentrate (MC) on physiological indices and functional performance was examined following a bout of high-intensity stochastic cycling. Trained cyclists (n = 16) were equally divided into 2 groups (MC or isoenergetic placebo (PLA)) and consumed 30 mL of supplement, twice per day for 8 consecutive days. On the fifth day of supplementation, participants completed a 109-min cycling trial designed to replicate road race demands. Functional performance (maximum voluntary isometric contraction (MVIC), cycling efficiency, 6-s peak cycling power) and delayed onset muscle soreness were assessed at baseline, 24, 48, and 72 h post-trial. Blood samples collected at baseline, immediately pre- and post-trial, and at 1, 3, 5, 24, 48, and 72 h post-trial were analysed for indices of inflammation (interleukin (IL)-1β, IL-6, IL-8, tumor necrosis factor alpha, high-sensitivity C-reactive protein (hsCRP)), oxidative stress (lipid hydroperoxides), and muscle damage (creatine kinase). MVIC (P < 0.05) did not decline in the MC group (vs. PLA) across the 72-h post-trial period and economy (P < 0.05) was improved in the MC group at 24 h. IL-6 (P < 0.001) and hsCRP (P < 0.05) responses to the trial were attenuated with MC (vs. PLA). No other blood markers were significantly different between MC and PLA groups. The results of the study suggest that Montmorency cherry concentrate can be an efficacious functional food for accelerating recovery and reducing exercise-induced inflammation following strenuous cycling exercise.

    We previously reported that Tricholoma matsutake and Tricholoma fulvocastaneum, ectomycorrhizal basidiomycetes that associate with Pinaceae and Fagaceae, respectively, in the Northern Hemisphere, could interact in vitro as a root endophyte of somatic plants of Cedrela odorata (Meliaceae), which naturally harbors arbuscular mycorrhizal fungi in South America, to form a characteristic rhizospheric colony or "shiro". We questioned whether this phenomenon could have occurred because of plant-microbe interactions between geographically separated species that never encounter one another in nature. In the present study, we document that these fungi formed root endophyte interactions and shiro within 140 days of inoculation with somatic plants of Prunus speciosa (=Cerasus speciosa, Rosaceae), a wild cherry tree that naturally harbors arbuscular mycorrhizal fungi in Japan. Compared with C. odorata, infected P. speciosa plants had less mycelial sheath surrounding the exodermis, and the older the roots, especially main roots, the more hyphae penetrated. In addition, a large number of juvenile roots were not associated with hyphae. We concluded that such root endophyte interactions were not events isolated to the interactions between exotic plants and microbes but could occur generally in vitro. Our pure culture system with a somatic plant allowed these fungi to express symbiosis-related phenotypes that varied with the plant host; these traits are innately programmed but suppressed in nature and could be useful in genetic analyses of plant-fungal symbiosis.

    Our gas chromatography-mass spectrometry method--developed for the simultaneous quantitation of mono-, di-, and trisaccharides, sugar alcohols, caboxylic and amino acids, measured as their trimethylsilyl-(oxime) ether/ester derivatives, from one solution by a single injection, prepared in the presence of the fruit matrix--has been extended/utilized for special purposes. The compositions of (i) freshly harvested and stored sour cherries (Prunus cerasus), (ii) apples obtained from organic and integrated productions (Malus domestica), and (iii) green and ripe bers (Zizyphus mauritiana L.) were compared. On the basis of earlier, basic researches (derivatization, quantitation, and fragmentation studies of authentic compounds), we demonstrate the reproducible quantitation of the main and minor constituents in a wide concentration range (approximately 1 x 10(-)(3) to >/=40%, in total up to < or =98%, calculated on dry matter basis of the fruit matrices). Reproducibility of quantitations, calculated on the basis of their total ion current values, provided an average reproducibility of 3.3 (sour cherries), 6.2 (apple), and 4.3 (ber) RSD %, respectively.

    Plum curculio, Conotrachelus nenuphar (Herbst) (Coleoptera: Curculionidae), adults were exposed to field-aged residues of thiamethoxam, acetamiprid, thiacloprid, indoxacarb, or azinphos-methyl on tart cherry, Prunus cerasus L. variety Montmorency. At 1, 3, 7, and 14 d postapplication, fruit were sampled for chemical residues, and bioassays were used to assess beetle mortality and plant tissue injury. Azinphos-methyl had lethal activity within 1 d of exposure at all postapplication intervals and significant fruit protection extended to 14 d postapplication. All of the neonicotinoids had lethal activity at 3 d posttreatment, with acetamiprid activity extending to 7 d. Antifeedant and oviposition deterrent effects were seen with thiamethoxam and thiacloprid; damage incidence was significantly reduced in the absence of significant beetle mortality or intoxication. Thiamethoxam and acetamiprid penetrated into leaf and fruit tissue and were detected in the interior tissues at 14 d postapplication, but interior thiacloprid residues were not detected after day 1. Indoxacarb provided some fruit protection out to 7 d postapplication, and 14-d-old residues intoxicated beetles, but the slow action of this compound allowed significant damage to occur before beetles were incapacitated. Indoxacarb was only detected as a surface residue after the first day postapplication. These data on the plant-insect-chemistry interactions will support use and management decisions as compounds with acute contact activity are phased out. PMID:20857728

  2. Carbohydrate production, balance and translocation in leaves, shoots and fruits of Montmorency sour cherry

    Kappes, E.M.

    1986-01-01

    Carbohydrate production, export and use were studied for different organs of sour cherry (Prunus cerasus L. Montmorency). Gross carbohydrate (/sup 14/CO/sub 2/) export started between 27.2 and 77.6% of full leaf expansion. The 10th leaf developing started export later than the 7th leaf, suggesting that higher carbohydrate availability during leaf expansion delays export initiation. In support of this, gross export started earlier (44.4-52.4% full expansion) after source leaf removal, than in the control (77.6%). Translocation was primarily vertical (following orthostichies). Most leaves of fruiting shoots exported bidirectionally to the apex and fruits, only leaves closest to fruits exported exclusively to fruits during rapid cell division (Stage I) and rapid cell expansion (Stage III). Net export, determined from carbohydrate balance models started at 17 and 51% expansion for the 7th and terminal leaf, and at 26.5% of shoot elongation. Cumulative carbohydrate production of the 7th and terminal leaves during the first 9 and 11 days after emergence, exceeded carbohydrate accumulated at final size, 464.2 and 148.9 mg. A fruit carbohydrate balance was developed to determine contributions by fruit photosynthesis and fruit respiration, and to identify periods of greatest carbohydrate import. Fruit photosynthesis during development was characterized under different environmental conditions. Gross photosynthesis and chlorophyll content per fruit increased to a maximum during stage II and decreased thereafter. Gross photosynthesis approached a maximum at 40/sub 0/C. Since dark respiration increased exponentially over the same temperature range, net photosynthesis reached a maximum at 18/sup 0/C. Photorespiration was not detected.

    Sugars, organic acids, carotenoids, tocopherols, chlorophylls, and phenolic compounds were quantified in fruit of 4 wild growing Prunus species (wild cherry, bird cherry, blackthorn, and mahaleb cherry) using HPLC-DAD-MSn. In wild Prunus, the major sugars were glucose and fructose, whereas malic and citric acids dominated among organic acids. The most abundant classes of phenolic compounds in the analyzed fruit species were anthocyanins, flavonols, derivatives of cinnamic acids, and flavanols. Two major groups of anthocyanins measured in Prunus fruits were cyanidin-3-rutinoside and cyanidin-3-glucoside. Flavonols were represented by 19 derivatives of quercetin, 10 derivatives of kaempferol, and 2 derivatives of isorhamnetin. The highest total flavonol content was measured in mahaleb cherry and bird cherry, followed by blackthorn and wild cherry fruit. Total phenolic content varied from 2373 (wild cherry) to 11053 mg GAE per kg (bird cherry) and ferric reducing antioxidant power antioxidant activity from 7.26 to 31.54 mM trolox equivalents per kg fruits.

    2002-10-01

    Sequences from s6pdh, a gene that encodes sorbitol-6-phosphate dehydrogenase in the Rosaceae, are used to reconstruct the phylogeny of 22 species of Prunus. The s6pdh sequences alone and in combination with previously published sequences of the internal transcribed spacer (ITS) and the cpDNA trnL-trnF spacer are analyzed using parsimony and maximum likelihood methods. Both methods reconstructed the same phylogeny when s6pdh sequences are used alone and in combination with ITS and trnL-trnF, and the topology is in agreement with previous studies that used a larger sample size. The s6pdh sequences have about twice as many informative sites as ITS. A molecular clock is rejected for s6pdh, most likely due to greater rates of evolution in subgenera Padus and Laurocerasus than in the rest of the genus. Phylogenetic reconstruction of Prunus as determined by analysis of the combined data set suggests an early split into two clades. One is composed of subgenera Cerasus, Laurocerasus, and Padus. The second includes subgenera Amygdalus, Emplectocladus, and Prunus. Species of section Microcerasus (formerly in subgenus Cerasus) are nested within subgenus Prunus. The order of branching and relationships among early diverging lineages is weakly supported, as a result of very short branches that may indicate rapid radiation. PMID:21665596

    Seasonal distributions of the western cherry fruit fly, Rhagoletis indifferens Curran (Diptera: Tephritidae), in sweet cherry (Prunus avium (L.) L.) (major host), black hawthorn (occasional developmental host) (Crataegus douglasii Lindley), and other trees were determined in a ponderosa pine ecosystem in Washington state, USA. The hypothesis that most fly dispersal from cherry trees occurs after fruit senesce or drop was tested, with emphasis on movement to black hawthorn trees. Sweet cherry fruit developed earlier than black hawthorn, bitter cherry (common host), choke cherry, and apple fruit. Flies were usually captured first in sweet cherry trees but were caught in bitter cherry and other trees throughout the season. Peak fly capture periods in sweet cherry began around the same time or slightly earlier than in other trees. However, peak fly capture periods in black hawthorn and other nonsweet cherry trees continued after peak periods in sweet cherry ended, or relative fly numbers within sweet cherry declined more quickly than those within other trees. Larvae were reared from sweet and bitter cherry but not black hawthorn fruit. Results provide partial support for the hypothesis in that although R. indifferens commonly disperses from sweet cherry trees with fruit, it could disperse more, or more flies are retained in nonsweet cherry trees after than before sweet cherries drop. This could allow opportunities for the flies to use other fruit for larval development. Although R. indifferens infestation in black hawthorn was not detected, early season fly dispersal to this and other trees and fly presence in bitter cherry could make fly management in sweet cherry difficult.

    This paper presents a comprehensive analytical methodology, based on 'in-time' and 'in-space' tandem mass spectrometry (MS) techniques, to identify and quantify flavonoid compounds in a typical Italian sweet cherry cultivar (cv. Ferrovia). Five anthocyanins, four flavan-3-ols and nine flavonols were determined by means of hyphenated high-performance liquid chromatography - multi-stage MS (HPLC-MS(n)) analyses (MS(n) up to MS(4)), among which quercetin-3-O-rutinoside-7-O-glucoside, kaempferol-3-O-rutinoside-7-O-glucoside, quercetin-3-O-galactosyl-rhamnoside and quercetin-3-O-coumaroylglucoside were tentatively identified in sweet cherries for the first time. Ultrafast HPLC and tandem MS (UHPLC-MS/MS) analyses through multiple reaction monitoring experiments showed that cyanidin-3-O-rutinoside and cyanidin-3-O-glucoside were the main anthocyanins of cv. Ferrovia at maturity. Moreover, consistent levels of catechin and epicatechin as well as quercetin-3-O-rutinoside and kaempferol-3-O-rutinoside were also found. Because flavonoids have been ascribed as potential health-promoting compounds, gathered findings provide new insight into the knowledge of the quali-quantitative profile of these phytochemicals into a widespread fruit such as sweet cherry.

    It is demonstrated that closely related viruses within the family Betaflexiviridae are associated with a number of diseases that affect sweet cherry (Prunus avium) and other Prunus spp. Cherry rusty mottle-associated virus (CRMaV) is correlated with the appearance of cherry rusty mottle disease (CRMD), and Cherry twisted leaf-associated virus (CTLaV) is linked to cherry twisted leaf disease (CTLD) and apricot ringpox disease (ARPD). Comprehensive analysis of previously reported full genomic sequences plus those determined in this study representing isolates of CTLaV, CRMaV, Cherry green ring mottle virus, and Cherry necrotic rusty mottle virus revealed segregation of sequences into four clades corresponding to distinct virus species. High-throughput sequencing of RNA from representative source trees for CRMD, CTLD, and ARPD did not reveal additional unique virus sequences that might be associated with these diseases, thereby further substantiating the association of CRMaV and CTLaV with CRMD and CTLD or ARPD, respectively. Based on comparison of the nucleotide and amino acid sequence identity values, phylogenetic relationships with other triple-gene block-coding viruses within the family Betaflexiviridae, genome organization, and natural host range, a new genus (Robigovirus) is suggested.

    The flavonol synthase gene is an important gene involved in the flavonoid biosynthesis pathway. A full-length cDNA sequence of FLS gene, PaFLS (GenBank accessionn number:JQ289290), was cloned from the young leaves of Prunus avium L. by using RT-PCR and RACE method. The full-length cDNA of PaFLS was 1 077 bp with an open reading frame of 1 014 bp, which encoded a putative protein of 337 amino acids with a molecular weight of about 38 kDa and an isoelectric point of 5.58. GenBank conserved domain search and function analysis revealed that PaFLS belonged to the 2-oxoglutarate iron-dependent oxygenase (2OG-Fell_Oxy) family. Sequence analysis showed that the homologies of FLS protein from P. avium with Malus domestica, Pyrus communis and Fragaria ananassa were 99% ,97% and 77% , respectively. The prokaryotic expression system of pGEX-4T-1 /PaFLS was constructed and transformed into E.coli BL21. The protein expression was induced by 0.5 mmol/L IPTG. A 65 kDa fusion protein was detected by SDS-PAGE. The expression levels of PaFLS in different tissues of plants were analyzed by quantitative real-time PCR. Higher level of transcription was observed in the flowers than that in the fruits, pholems and leaves, which might be associated with pollinator attraction and pollen germination.%为了解黄酮醇合酶在甜樱桃类黄酮生物合成途径中的作用,根据其他物种已知的FLS cDNA保守序列设计简并引物,采用RT-PCR和RACE的技术,从甜樱桃(Prunus avium.L)嫩叶中扩增获得FLS cDNA全长,命名为PaFLS(GenBank登录号:JQ289290).该基因cDNA全长为1 077 bp,开放阅读框为1 014 bp,编码337个氨基酸,分子质量为38 ku,等电点pI为5.58.生物信息学分析表明PaFLS属于依赖2-酮戊二酸的双加氧酶家族(2OG-FeII_Oxy),该基因所编码的氨基酸序列与苹果、梨和草莓的同源性分别为99%、97%和77%.将该基因重组到表达载体pGEX4T-1中进行原核表达,电泳检测到一条约为65 ku

    Melatonin is a well-known molecule which possesses many beneficial effects on human health. Many agriculture products provide natural melatonin in the diet. Cherry is one such fruit as they are rich in melatonin. In order to understand the biological roles of melatonin in cherry fruit, melatonin synthesis and its changes over 24 hr period were systematically monitored both during their development and in the ripe cherries in two cultivars, 'Hongdeng' (Prunus avium L. cv. Hongdeng) and 'Rainier' (Prunus avium L. cv. Rainier). It was found that both darkness and oxidative stress induced melatonin synthesis, which led to dual melatonin synthetic peaks during a 24 hr period. The high levels of malondialdehyde induced by high temperature and high intensity light exposure were directly related to up-regulated melatonin production. A primary function of melatonin in cherry fruits is speculated to be as an antioxidant to protect the cherry from the oxidative stress. Importantly, plant tryptophan decaboxylase gene (PaTDC) was identified in cherry fruits. Our data shows that PaTDC expression is positively related to the melatonin production in the cherry. This provides additional information to suggest that tryptophan decaboxylase is a rate-limiting enzyme of melatonin synthesis in plants. PMID:23480341

One year old, cherry trees were exposed 8 hours of day length and 16 hours of dark period for short day conditions and 16 hours of light and 8 hours of dark period for long day conditions. We also compared the acclimatization pattern of cherry trees with hybrid aspen (Populus tremula ×Populus tremuloides trees. LT50 values indicated that short day and long day conditions did not alter the cold hardiness of cherry trees. Under the same experimental conditions hybrid aspen trees were affected from different photoperiods. Aspen trees exposed to short day conditions were hardier than the trees exposed to long day conditions. We also investigated the acclimatization the patterns of basal and apical parts of the branches both in cherry and aspen trees. There were no significant differences in cold hardiness of the basal and apical parts of the branches in aspen and cherry trees.

    The present study evaluates a hypothesis that sour cherry (Prunus cerasus) seed extracts (SCE) modulate CD3+ T lymphocyte activity in ways predictive of potential for uses of SCE in management of inflammatory diseases. Peripheral blood mononuclear cells (PBMC) from 12 type 2 diabetes (T2DM) patients and eight healthy control subjects were cultured 24 h with 100 ng/ml lipopolysaccharide (LPS) to increase inflammatory signaling and co-incubated with 0.5-100 µg/ml SCE. Cultures were evaluated by two-color flow cytometry for percent representation of CD3+ IL8+ and CD3+TNF-α cells which express interleukin-8 (IL-8), and tumor necrosis factor-α, (TNF-α+) respectively, and by enzyme-linked immunoassay for lymphocyte-associated heme oxygenase-1 (HO-1, known to be induced by SCE). SCE dosage ranges of 0.5-100 µg/ml in cell cultures significantly suppressed LPS-increased CD3+TNF-α+ and CD3+IL8+ representation from all participants (p < 0.05), with greater pharmacological effect noted in suppression of CD3+TNF-α+ noted in cells from T2DM patients versus healthy control subjects. These effects correlated with increased HO-1 expression in SCE-treated PBMC from all subjects (p < 0.05). Since TNF-α and IL-8 are diagnostic/prognostic biomarkers for many inflammatory syndromes, the capacity of SCE to down-regulate representation of cells that express them suggests potential for therapeutic use of SCE in T2DM and other diseases.

    Full Text Available Abstract Background Domestication and breeding involve the selection of particular phenotypes, limiting the genomic diversity of the population and creating a bottleneck. These effects can be precisely estimated when the location of domestication is established. Few analyses have focused on understanding the genetic consequences of domestication and breeding in fruit trees. In this study, we aimed to analyse genetic structure and changes in the diversity in sweet cherry Prunus avium L. Results Three subgroups were detected in sweet cherry, with one group of landraces genetically very close to the analysed wild cherry population. A limited number of SSR markers displayed deviations from the frequencies expected under neutrality. After the removal of these markers from the analysis, a very limited bottleneck was detected between wild cherries and sweet cherry landraces, with a much more pronounced bottleneck between sweet cherry landraces and modern sweet cherry varieties. The loss of diversity between wild cherries and sweet cherry landraces at the S-locus was more significant than that for microsatellites. Particularly high levels of differentiation were observed for some S-alleles. Conclusions Several domestication events may have happened in sweet cherry or/and intense gene flow from local wild cherry was probably maintained along the evolutionary history of the species. A marked bottleneck due to breeding was detected, with all markers, in the modern sweet cherry gene pool. The microsatellites did not detect the bottleneck due to domestication in the analysed sample. The vegetative propagation specific to some fruit trees may account for the differences in diversity observed at the S-locus. Our study provides insights into domestication events of cherry, however, requires confirmation on a larger sampling scheme for both sweet cherry landraces and wild cherry.

    Full Text Available The objective of this work was to evaluate variability in reproductive biology traits and the correlation between them in genotypes of 'Oblačinska' sour cherry (Prunus cerasus. High genetic diversity was found in the 41 evaluated genotypes, and significant differences were observed among them for all studied traits: flowering time, pollen germination, number of fruiting branches, production of flower and fruit, number of flowers per bud, fruit set, and limb yield efficiency. The number of fruiting branches significantly influenced the number of flower and fruit, fruit set, and yield efficiency. In addition to number of fruiting branches, yield efficiency was positively correlated with fruit set and production of flower and fruit. Results from principal component analysis suggested a reduction of the reproductive biology factors affecting yield to four main characters: number and structure of fruiting branches, flowering time, and pollen germination. Knowledge of the reproductive biology of the 'Oblačinska' genotypes can be used to select the appropriate ones to be grown or used as parents in breeding programs. In this sense, genotypes II/2, III/9, III/13, and III/14 have very good flower production and satisfactory pollen germination.O objetivo deste trabalho foi avaliar a variabilidade de características da biologia reprodutiva e a correlação entre elas, em genótipos da cereja ácida (Prunus cerasus 'Oblačinska'.

    Sequences of the chloroplast ndhF gene and the nuclear ribosomal ITS regions are employed to reconstruct the phylogeny of Prunus (Rosaceae), and evaluate the classification schemes of this genus. The two data sets are congruent in that the genera Prunus s.l. and Maddenia form a monophyletic group, with Maddenia nested within Prunus. However, the ndhF data set is incongruent with the ITS data supporting two major groups within Prunus: one consisting of subgenera Laurocerasus (including Pygeum) and Padus as well as the genus Maddenia and another of subgenera Amygdalus, Cerasus, and Prunus. The ITS data, on the other hand, support a clade composed of subgenera Amygdalus and Prunus and Prunus sect. Microcerasus in addition to a paraphyletic grade of subgenera Laurocerasus and Padus (and the genus Maddenia) taxa. In general, the subgeneric classifications of Prunus s.l. are not supported. The ITS and ndhF phylogenies differ mainly in interspecific relationships and the relative position of the Padus/Laurocerasus group. Both ITS and ndhF data sets suggest that the formerly recognized genus Pygeum is polyphyletic and that the distinction of the subgenera Padus and Laurocerasus is not supported. The biogeographic interactions of the temperate and tropical members in the Padus/Laurocera- sus/Maddenia alliance including Pygeum are shown to be highly dynamic and complex.

    Full Text Available Sweet cherry trees (Prunus avium L. are susceptible to a range of diseases, but there have been no studies to date about the viral infection of sweet cherry trees in Spain. To determine the phytosanitary status of Spanish sweet cherry plantations, the incidence and leaf symptoms induced by Prune dwarf (PDV, Prunus necrotic ringspot (PNRSV and Apple chlorotic leaf spot (ACLSV viruses were investigated during 2009. Young leaf samples were taken from 350 sweet cherry trees, corresponding to 17 cultivars, and were analysed by double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA. To associate the leaf symptoms with the virus, 50 mature leaves from each infected tree were visually inspected during the summer. The ELISA results revealed that 72 % of sweet cherry trees were infected by at least one of the viruses. PDV occurred in all sampled cultivars and presented the highest infection rate, followed by ACLSV and PNRSV. A high number of trees showed asymptomatic, in both single and mixed infections. The leaf symptoms associated with the viruses involved generalized chlorosis around the midvein (PDV, chlorotic and dark brown necrotic ringspots on both secondary veins and intervein regions (PNRSV, chlorotic and reddish necrotic ringspots (ACLSV and generalized interveinal chlorosis (PDV-PNRSV.

    Full Text Available The studies concerning the effect of the times and the methods of budding on the growth of young cherry trees were conducted in the years 1997-2000 at Felin Experimental Farm of Lublin Agricultural University. The objects of investigations were the young cherry trees obtained as a result of budding of mahaleb cherry (Prunus mahaleb L. and sweet cherry (Prunus avium L. seedlings in the way by the chip budding-15th July and T-budding-on the 15th July and the 1st September. The used terms and budding methods did not affect the bud taking and the quality of cherry trees during three years studies. Chip budding of the sweet cherry on the 15th July was the most effective way of this seedling budding. Late budding-on the 1st September-did not change the efficiency of the nursery only in case of mahaleb cherry. The highest number-33 000 of the young trees, average per 1 ha was got as a result of the chip and "T" mahaleb cherry budding on the 1st September.

    Full Text Available Prunus mahaleb is widely used as rootstocks particularly on calcareous and dry soils for both sweet and sour cherry cultivars in Turkey. Genetic diversity and relationships among members of Prunus mahaleb including 29 preselected rootstock candidate accessions from Tokat region in Turkey were investigated by using 15 ISSR markers. The study revealed high genetic diversity among accessions, detecting 138 fragments, of which 103 (75% were polymorphic. The number of polymorphic bands per primer was between 3-13, with average of 6.86. The primers 890 and 891 gave the highest polymorphism ratio (100%. The UPGMA dendrogram and the principal coordinate analysis revealed a clear differentiation among accessions. Reference rootstock, SL-64 clustered separately. The study demonstrates that ISSRs provide promising marker tools in revealing genetic diversity and relationships in Prunus mahaleb rootstock candidate accessions and can contribute to efficient identification, conservation, and utilization of germplasm for rootstock improvement through conventional as well as molecular breeding approaches.

    Full Text Available Iran is one of the chief origins of subgenus Cerasus germplasm. In this study, the genetic variation of new Iranian sour cherries (which had such superior growth characteristics and fruit quality as to be considered for the introduction of new cultivars was investigated and identified using 23 intersimple sequence repeat (ISSR markers. Results indicated a high level of polymorphism of the genotypes based on these markers. According to these results, primers tested in this study specially ISSR-4, ISSR-6, ISSR-13, ISSR-14, ISSR-16, and ISSR-19 produced good and various levels of amplifications which can be effectively used in genetic studies of the sour cherry. The genetic similarity among genotypes showed a high diversity among the genotypes. Cluster analysis separated improved cultivars from promising Iranian genotypes, and the PCoA supported the cluster analysis results. Since the Iranian genotypes were superior to the improved cultivars and were separated from them in most groups, these genotypes can be considered as distinct genotypes for further evaluations in the framework of breeding programs and new cultivar identification in cherries. Results also confirmed that ISSR is a reliable DNA marker that can be used for exact genetic studies and in sour cherry breeding programs.

    The western cherry fruit fly, Rhagoletis indifferens Curran (Diptera: Tephritidae), is an endemic herbivore of bitter cherry, Prunus emarginata (Douglas ex Hooker) Eaton, but ∼100 years ago established on earlier-fruiting domesticated sweet cherry, Prunus avium (L.) L. Here, we determined if eclosion times of adult R. indifferens from sweet and bitter cherry differ according to the phenology of their respective host plants and if eclosion times of the host-specific parasitoid Diachasma muliebre (Muesebeck) (Hymenoptera: Braconidae) attacking bitter and sweet cherry flies differ according to the eclosion phenology of their fly hosts. Fly pupae from sweet and bitter cherry fruit were collected from sympatric and allopatric sites in Washington state, and chilled at 5°C. Because timing of eclosion in R. indifferens depends on chill duration, eclosion time in wasps could also vary with chill duration. To account for this, fly pupae were chilled for 1, 2, 2.5, 3, 4, 6, or 8 mo. Both flies and wasps eclosed earlier with longer chill durations. Eclosion times of sweet and bitter cherry flies from a sympatric site in central Washington did not differ. However, at allopatric sites in northwestern and central Washington, bitter cherry flies eclosed later than sweet and bitter cherry flies at the sympatric site. Correspondingly, D. muliebre parasitizing a more isolated bitter cherry fly population eclosed later than D. muliebre parasitizing earlier-emerging sweet and bitter cherry fly populations. These results provide evidence for D. muliebre rapidly responding to changes in host plant shifts by R. indifferens. PMID:26314048

    Full Text Available Rain-induced cracking in fruits of sweet cherry (Prunus avium L. is a problem in most producing areas of the world and causes significant economic losses. Different orchard management practices have been employed to reduce the severity of this problem, although a complete solution is not yet available. Fruit cracking is a complex phenomenon and there are many factors that seem to be involved in its development. During the last decade, genomic and biochemical approaches have provided new insights on the different mechanisms that could be involved in the differential susceptibility shown by commercial cultivars. For instance, sweet cherry genome and transcriptome sequencing information have provided new opportunities to study the expression and structure of genes involved in cracking, which may help in the development of new tolerant cultivars. The present review summarizes, discuss, and integrate most of the recently generated information in cultural practices, physiology, biochemistry, and genetics in relation to cracking in sweet cherries.

    Full Text Available Despite the agronomical importance and high synteny with other Prunus species, breeding improvements for cherry have been slow compared to other temperate fruits, such as apple or peach. However, the recent release of the peach genome v1.0 by the International Peach Genome Initiative and the sequencing of cherry accessions to identify Single Nucleotide Polymorphisms (SNPs provide an excellent basis for the advancement of cherry genetic and genomic studies. The availability of dense genetic linkage maps in phenotyped segregating progenies would be a valuable tool for breeders and geneticists. Using two sweet cherry (Prunus avium L. intra-specific progenies derived from crosses between 'Black Tartarian' × 'Kordia' (BT×K and 'Regina' × 'Lapins'(R×L, high-density genetic maps of the four parental lines and the two segregating populations were constructed. For BT×K and R×L, 89 and 121 F(1 plants were used for linkage mapping, respectively. A total of 5,696 SNP markers were tested in each progeny. As a result of these analyses, 723 and 687 markers were mapped into eight linkage groups (LGs in BT×K and R×L, respectively. The resulting maps spanned 752.9 and 639.9 cM with an average distance of 1.1 and 0.9 cM between adjacent markers in BT×K and R×L, respectively. The maps displayed high synteny and co-linearity between each other, with the Prunus bin map, and with the peach genome v1.0 for all eight LGs (LG1-LG8. These maps provide a useful tool for investigating traits of interest in sweet cherry and represent a qualitative advance in the understanding of the cherry genome and its synteny with other members of the Rosaceae family.

    Full Text Available The investigations were made in the experimental sour cherry orchard from the Institute of Agriculture, Kyustendil, Bulgaria, during the period 2010-2014, in order to compare conventional and integrated sour cherry protection against cherry leaf spot and cherry fruit fly. Two variants were investigated, with two different treatment approaches for the control of cherry leaf spot and cherry fruit fly. Variant 1 – cherry leaf spot was controlled by protective treatments with dodin and tebuconazole + trifloxystrobin and cherry fruit fly was controlled by treatments with deltametrin and thiacloprid, independently of density. Variant 2 - cherry leaf spot was controlled by post-infection (curative treatments with tebuconazole + trifloxystrobin and cherry fruit fly was controlled by treatments based on biological threshold: 10-11 cherry fruit fly females caught in traps up to the moment for chemical treatment. It was established that Blumeriella japii can be successfully controlled by post-infection treatments and by this the number of insecticide treatments was reduced. The treatments against cherry fruit fly can be avoided or reduced when the attack control is based on the biological threshold established in the studied area.

    Understanding the drivers of phenological events is vital for forecasting species' responses to climate change. We developed flexible Bayesian survival regression models to assess a 29-year, individual-level time series of flowering phenology from four taxa of Japanese cherry trees (Prunus spachiana, Prunus × yedoensis, Prunus jamasakura, and Prunus lannesiana), from the Tama Forest Cherry Preservation Garden in Hachioji, Japan. Our modeling framework used time-varying (chill and heat units) and time-invariant (slope, aspect, and elevation) factors. We found limited differences among taxa in sensitivity to chill, but earlier flowering taxa, such as P. spachiana, were more sensitive to heat than later flowering taxa, such as P. lannesiana. Using an ensemble of three downscaled regional climate models under the A1B emissions scenario, we projected shifts in flowering timing by 2100. Projections suggest that each taxa will flower about 30 days earlier on average by 2100 with 2-6 days greater uncertainty around the species mean flowering date. Dramatic shifts in the flowering times of cherry trees may have implications for economically important cultural festivals in Japan and East Asia. The survival models used here provide a mechanistic modeling approach and are broadly applicable to any time-to-event phenological data, such as plant leafing, bird arrival time, and insect emergence. The ability to explicitly quantify uncertainty, examine phenological responses on a fine time scale, and incorporate conditions leading up to an event may provide future insight into phenologically driven changes in carbon balance and ecological mismatches of plants and pollinators in natural populations and horticultural crops.

    Partial sequences of the mitochondrial COI gene of forty eight European and two Turkish population samples of Myzus cerasi from different winter hosts (Prunus spp.) were subjected to phylogenetic analyses. The analysed M. cerasi samples emerged as paraphyletic relative to a Myzus borealis sample used as an out-group, and formed two major clades in neighbor joining, maximum parsimony, maximum likelihood and Bayesian inference trees, corresponding to subspecies living specifically on Prunus avium and P. cerasus. Multivariate discriminant analysis (method of canonical variates) was applied to find out if morphological variation of samples correlated with mitochondrial COI and host plant information. Mean scores on the first two canonical variables clustered samples fully in accordance with their COI haplotypes and host plants confirming the existence of two morphologically similar winter host - specific subspecies of M. cerasi in Europe. No single morphological character enabled satisfactory discrimination between apterous viviparous females of the two subspecies. A three-character linear discriminant function enabled 92.37% correct identification of apterous viviparous females of M. cerasi cerasi (n = 118) and 93.64% of M. cerasi pruniavium (n = 110). A key for the morphological identification of the two subspecies is presented and their taxonomic status is discussed. PMID:24715766

    Cherries, and in particular sweet cherries, are a nutritionally dense food rich in anthocyanins, quercetin, hydroxycinnamates, potassium, fiber, vitamin C, carotenoids, and melatonin. UV concentration, degree of ripeness, postharvest storage conditions, and processing, each can significantly alter the amounts of nutrients and bioactive components. These constituent nutrients and bioactive food components support the potential preventive health benefits of cherry intake in relation to cancer, cardiovascular disease, diabetes, inflammatory diseases, and Alzheimer's disease. Mechanistically, cherries exhibit relatively high antioxidant activity, low glycemic response, COX 1 and 2 enzyme inhibition, and other anti-carcinogenic effects in vitro and in animal experiments. Well-designed cherry feeding studies are needed to further substantiate any health benefits in humans. PMID:21229414

    Cuticle composition and structure may be relevant factors affecting the storage potential of fruits, but very few studies have analyzed fruit cuticle composition from a postharvest perspective. In this work, the chemical composition of waxes and cutin (major cuticular components) was analyzed in cuticle samples isolated from "Celeste" and "Somerset" cherries (Prunus avium L.) after cold storage at 0 °C. Total cuticle amounts per surface unit (μg cm(-2)) increased along with cold storage. The triterpene ursolic acid, the alkane nonacosane, linoleic acid, and β-sitosterol were the most abundant components of cuticular waxes, whereas cutin composition was dominated by C18-type monomers. In spite of being comprised of similar chemical families, cultivar-related differences were found regarding the abundance and the evolution of some compound families during cold storage. To the best of our knowledge, this is the first report on changes in cuticle composition of sweet cherry during postharvest storage.

The triterpene ursolic acid, the alkane nonacosane, linoleic acid, and β-sitosterol were the most abundant components of cuticular waxes, whereas cutin composition was dominated by C18-type monomers. In spite of being comprised of similar chemical families, cultivar-related differences were found regarding the abundance and the evolution of some compound families during cold storage. To the best of our knowledge, this is the first report on changes in cuticle composition of sweet cherry during postharvest storage. PMID:25089645

    A multiplex reverse transcription-polymerase chain reaction (mRT-PCR) was developed and standardized for the simultaneous detection of four cherry viruses: Cherry virus A (CVA, Genus; Capillovirus), Cherry necrotic rusty mottle virus (CNRMV, unassigned species of the Betaflexiviridae), Little cherry virus 1 (LChV-1, Genus; Closterovirus) and Prunus necrotic ringspot virus (PNRSV, Genus; Ilarvirus) with nad5 as plant internal control. A reliable and quick method for total plant RNA extraction from pome and stone fruit trees was also developed. To minimize primer dimer formation, a single antisense primer for CVA and CNRMV was used. A mixture of random hexamer and oligo (dT) primer was used for cDNA synthesis, which was highly suited and economic for multiplexing. All four viruses were detected successfully by mRT-PCR in artificially created viral RNA mixture and field samples of sweet cherry. The identity of the viruses was confirmed by sequencing. The assay could detect above viruses in diluted cDNA (10(-4)) and RNA (10(-3), except PNRSV which was detected only till ten times lesser dilution). The developed mRT-PCR will not only be useful for the detection of viruses from single or multiple infections of sweet cherry plants but also for other stone and pome fruits. The developed method will be therefore quite helpful for virus indexing, plant quarantine and certification programs. This is the first report for the simultaneous detection of four cherry viruses by mRT-PCR.

    A survey was conducted using a face to face questionnaire with 92 sweet cherry (Prunus avium L.) producers from 10 villages in five districts of the Isparta province where there is intensive sweet cherry production. The data collected was analyzed for the energy and economics of sweet cherry production. The results showed that the most energy consuming input for the different operations investigated was chemical fertilisers (45.35%), especially nitrogen (38.05%). The energy consumption for Diesel fuel was 21.53% of the total energy input. Although chemicals for plant protection had a small portion (1.45%) of the total energy input, the use of pesticide in sweet cherry production per hectare in the Isparta province was 5.36 times higher than that of Turkey's average, increasing the environmental risk problem. The energy use efficiency, defined as energy produced per unit of energy used, was 1.23. The specific energy of sweet cherry production was determined to be 3163.43 MJ tonnes{sup -1}. It was found that the direct and indirect energy inputs were 34.48% and 54.91% of the total energy input, respectively. Among the inputs, renewable energy sources constituted 16.34% of the total energy input, which was lower than that of the non-renewable resources (chemical fertilisers and Diesel fuel). The results showed that the net return from sweet cherry production in the surveyed farms was satisfactory, as demonstrated by the benefit-cost ratio of 2.53 calculated by dividing the gross value of production by the total cost of production per hectare.

    Full Text Available This study was conducted to determine the responses of ‘0900 Ziraat’ sweet cherry cultivar grafted on mazzard (Prunus avium L. and mahaleb (P. mahaleb L. rootstocks, to different irrigation water salinity levels. One year old sweet cherry trees were planted in 50-liter pots at Eğirdir Fruit Research Station (Isparta, Turkey. Four different irrigation water salinity levels (S1=0.3 dS m-1, S2=2.0 dS m-1, S3=4.0 dS m-1 and S4=6 dS m-1 were used for both variety/rootstock combinations. The results showed that sweet cherry trees grafted on mahaleb rootstocks extracted more water under saline conditions than the ones grafted on mazzard. Water salinity levels caused more damage on 0900/mazzard than on 0900/mahaleb. Towards the end of the growing period, plant deaths were detected in S3 and S4 treatments. While leaf water potential (LWP ranged from -1.54 to -3.33 MPa, stomatal conductance ranged from 26.8 to 199.5 mmol m-2 s-1. It was determined that both parameters decreased towards the end of the growing period for all treatments. Sodium (Na uptake was excluded by 0900/mahaleb rootstocks, but chloride (Cl− uptake was excluded only for higher saline conditions. As a result, mahaleb (P. mahaleb L. rootstock could be recommended to be used as rootstock for sweet cherry culture under saline conditions.

    Full Text Available Background: Non-enzymatic glycosylation of proteins is the major cause of diabetic complications. The inhibition of glycation process can reduce complications of diabetes. In the Iranian traditional medicine, the decoction (boiled extraction of Cerasus avium stalk is used as a hypoglycemic agent. The aim of this study was to investigate the in vitro inhibitory effects of decoction and ethanolic and aqueous extracts of Cerasus avium stalk on albumin glycation reaction. Methods: In this experimental study, first, the ethanolic, aqueous and decoction extracts of Cerasus avium stalk were prepared. Then, different concentrations of these extracts were prepared and added to albumin and glucose solutions. Finally, compared to control group that was not treated with any extracts, the albumin glycation rate in the groups treated with various concentrations of extracts was evaluated using TBA (thio-barbituric acid method. Results: The results showed that compared to control group, decoction of Cerasus avium stalk in the concentrations of 20, 10 and 2 mg/dl could reduce albumin glycation to 85.10±1.55, 72.35±1.75 and 51.25±1.22 %, respectively (P>0.001. Moreover, in the concentration of 20 mg/dl, the inhibitory effect of decoction of Cerasus avium stalk on the albumin glycation reaction was higher than those of aqueous (P=0.021 and ethanolic (P=0.009 extracts. Conclusion: The findings showed that the extracs of Cerasus avium stalk, in particular in the decoction form, could significantly reduce the rate of albumin glycation; therefore, it can be used for decreasing diabetes mellitus complications.

    Full Text Available Sour cherry cv. Marasca is Dalmatian cultivar from XVI century. Cultivation is limited on the north and central part of Dalmatia and on the part of the islands, where it achieves the best quality of fruit, high content of dry matter and sugar respectively, agreeable aroma and intense color. Sour cherry cv. Marasca is source of biologically active ingredients, organic and inorganic compounds, dietary fibers, aromatic compounds and high content of phenolic compounds, particularly anthocyanins and hormone melatonin. Many epidemiological studies showed that phenolic compounds have antioxidant and anti-inflammatory properties, and they have beneficial effect on human health. Marasca is rich with mentioned compounds. Physicochemical composition (total and soluble dry matter, pH value, total acidity during ripening of cv. Marasca ecotype Recta (Cerasus marasca recta grown in Zadar and Split area were determined. Total and soluble dry matter increased and pH value and total acidity showed little change during ripening. The content of phenolic compounds increased during ripening as well as content of anthocyanins, while antioxidant activity decreased with ripening. That indicates there was no correlation between antioxidant activity and content of total phenolic compounds.

    Full Text Available Sweet cherry, a non-climacteric fruit, is usually cold-stored during postharvest to prevent over-ripening. The aim of the study was to evaluate the role of abscisic acid (ABA on fruit growth and ripening of this fruit, considering as well its putative implication in over-ripening and effects on quality. We measured the endogenous concentrations of ABA during the ripening of sweet cherries (Prunus avium L. var. Prime Giant collected from orchard trees and in cherries exposed to 4ºC and 23ºC during 10d of postharvest. Furthermore, we examined to what extent endogenous ABA concentrations were related to quality parameters, such as fruit biomass, anthocyanin accumulation and levels of vitamins C and E. Endogenous concentrations of ABA in fruits increased progressively during fruit growth and ripening on the tree, to decrease later during postharvest at 23ºC. Cold treatment, however, increased ABA levels and led to an inhibition of over-ripening. Furthermore, ABA levels positively correlated with anthocyanin and vitamin E levels during preharvest, but not during postharvest. We conclude that ABA plays a major role in sweet cherry development, stimulating its ripening process and positively influencing quality parameters during preharvest. The possible influence of ABA preventing over-ripening in cold-stored sweet cherries is also discussed.

    Little cherry virus 2 (LChV2) (genus Ampelovirus) is the primary causal agent of little cherry disease (LCD) in sweet cherry (Prunus avium) in North America and other parts of the world. This mealybug-transmitted virus does not induce significant foliar symptoms in most sweet cherry cultivars, but does cause virus-infected trees to yield unevenly ripened small fruits with poor flavor. Most fruits from infected trees are unmarketable. In the present study, an isothermal reverse transcription-recombinase polymerase amplification (RT-RPA) technique was developed using LChV2 coat protein specific primers and probe. Detection of terminally labeled amplicons was achieved with a high affinity lateral flow strip. The RT-RPA is confirmed to be simple, fast, and specific. In comparison, although it retains the sensitivity of RT-PCR, it is a more cost-effective procedure. RT-RPA will be a very useful tool for detecting LChV2 from crude extracts in any growth stage of sweet cherry from field samples. PMID:24797461

    Full Text Available In flowering plants, self-incompatibility is an effective genetic mechanism that prevents self-fertilization. Most Prunus tree species exhibit a homomorphic gametophytic self-incompatibility (GSI system, in which the pollen phenotype is encoded by its own haploid genome. To date, no identification of S-alleles had been done in Prunus africana, the only member of the genus in Africa. To identify S-RNase alleles and hence determine S-genotypes in African cherry (Prunus africana from Mabira Forest Reserve, Uganda, primers flanking the first and second intron were designed and these amplified two bands in most individuals. PCR bands on agarose indicated 26 and 8 different S-alleles for second and first intron respectively. Partial or full sequences were obtained for all these fragments. Comparison with published S-RNase data indicated that the amplified products were S-RNase alleles with very high interspecies homology despite the high intraspecific variation. Against expectations for a locus under balancing selection, frequency and spatial distribution of the alleles in a study plot was not random. Implications of the results to breeding efforts in the species are discussed, and mating experiments are strongly suggested to finally prove the functionality of SI in P. africana.

    Temperature-related studies were conducted on Drosophila suzukii Matsumura (Diptera: Drosophilidae: Drosophilini). From 10-28°C, temperature had a significant impact on blueberries, Vaccinium corymbosum L. (Ericales: Ericaceae), and cherries, Prunus avium (L.) L. 1755 (Rosales: Rosaceae), important commercial hosts of D. suzukii. Temperature had a significant influence on D. suzukii developmental period, survival, and fecundity, with decreasing developmental periods as temperatures increased to 28°C. At 30°C, the highest temperature tested, development periods increased, indicating that above this temperature the developmental extremes for the species were approached. D. suzukii reared on blueberries had lower fecundity than reared on cherries at all temperatures where reproduction occurred. The highest net reproductive rate (R(o)) and intrinsic rate of population increase (r(m)) were recorded on cherries at 22°C and was 195.1 and 0.22, respectively. Estimations using linear and nonlinear fit for the minimum, optimal, and maximum temperatures where development can take place were respectively, 7.2, 28.1, and 42.1°C. The r(m) values were minimal, optimal, and maximal at 13.4, 21.0, and 29.3°C, respectively. Our laboratory cultures of D. suzukii displayed high rates of infection for Wolbachia spp. (Rickettsiales: Rickettsiaceae), and this infection may have impacted fecundity found in this study. A temperature-dependent matrix population estimation model using fecundity and survival data were run to determine whether these data could predict D. suzukii pressure based on environmental conditions. The model was applied to compare the 2011 and 2012 crop seasons in an important cherry production region. Population estimates using the model explained different risk levels during the key cherry harvest period between these seasons. PMID:24612968

    The changes in March mean temperatures in Edo (Tokyo), Japan, since the seventeenth century, were reconstructed using phenological data for the cherry blossoms of Prunus jamasakura deduced from old diaries and chronicles. The observations of the time of full blossoming and of cherry blossom viewing parties were acquired and used to construct a full-blossoming phenological data series for P. jamasakura. Phenological data from 207 of the years from 1601 to 1905 were used for this study. The reconstructed temperatures suggested the existence of two cold periods (the second half of the seventeenth century and the beginning of the nineteenth century), during which times the estimated March mean temperatures were about 4 °C and 5 °C, respectively. These two cold periods at Edo coincided with those reconstructed at Kyoto in previous studies. These cold periods coincided with two less extreme periods, the Maunder and Dalton minima, in the long-term solar variation cycle.

  2. Effects of alginate edible coating on quality and antioxidant properties in sweet cherry during postharvest storage

    2015-06-01

    Full Text Available Two sweet cherry (Prunus avium L. cultivars (“Big Lory” and “Grace Star”, were treated with 1%, 3% and 5% sodium alginate as an edible coating before storage. Analytical determinations were made after 7, 14 and 21 days of storage at 4°C. Cherries were analyzed for the following quality parameters: firmness, weight loss, titratable acidity, soluble solid content, external color, anthocyanin content, phenolic content and total antioxidant capacity. Alginate treatment at 3% delayed changes in most of the ripening parameters, weight and acidity losses, softening and color changes. However, the soluble solids content was not affected by the alginate fruit coating. In terms of the antioxidant properties, no significant results were obtained with the use of the alginate coating. The results of this study suggest that alginate treatments at 1% and 3% could be used as natural postharvest treatments in cherry cultivars with the aim of delaying the postharvest ripening process and maintaining fruit quality.

    Fruits of Lapins sweet cherry (Prunus avium L.) from 12-year-old trees on different rootstocks (F 12/1, Maxma 14, Piku 1, Edabriz, Gisela 5, Gisela 195/20, Weiroot 13, Weiroot 158, and Weiroot 72) were analyzed for pomological (fruit weight, % flesh of fruit weight, soluble solids content, titratable acidity, and firmness) and biochemical parameters (individual sugars, organic acids, and phenolic compounds) considering yield. For the first time, two procyanidins have been identified in sweet cherries using HPLC/MS: procyanidin B2 and procyanidin dimer (gamma(max) = 275 nm; [M - H](-) at m/z 577 and MS(2) fragments at m/z 425, 407, and 289). There were no significant differences between rootstocks in average yield per tree, except for Piku 1 (19.7 kg) with significantly the highest and Gisela 5 with significantly the lowest average yields per tree (7.7 kg). Significant differences in the measured parameters were ascertained among fruits of Lapins derived from different rootstock. Growing Lapins on Weiroot 72 and Edabriz resulted in high soluble solids content and fruit firmness. The lowest fruit firmness was measured on fruits from Weiroot 13, F 12/1, Gisela 195/20, and Maxma 14 trees. Fruits from Gisela 5 contained the lowest concentrations of glucose, fructose, sorbitol, sucrose, and citric acid, while fruits from F 12/1 contained the highest values of glucose, fructose, and shikimic acid. The content of phenolic compounds was the highest in fruits from Weiroot 72 tree, but the highest concentrations of procyanidin B2 and procyanidin dimer were ascertained in fruits from the Edabriz tree. Fruits from Weiroot 72 contained significantly higher concentration of phenols, bioactive compounds, compared to that in fruits from F 12/1. The content of individual and total anthocyanins did not differ significantly among rootstocks. PMID:20337477

    Full Text Available Wild cherry (Prunus avium L. is receiving increasing attention from foresters in Europe and Turkey for its fast growth, highly-valued wood and benefits for wildlife and biodiversity. Little documentation may be found concerning the selection of appropriate cultural treatments and the quality and types of seedlings used for wild cherry plantations. This study reports the effects of various combinations of intensive cultural treatments (including weed control, soil tillage, and fertilization and seedling types on early growth, survival, and nutrition of one-year-old wild cherry seedlings out-planted on four different sites in the western Black Sea Region of Turkey. After two years, early seedling survival and growth were clearly enhanced for potted seedlings. For bare-root seedlings, initial seedling root-collar diameter and height successfully correlated with survival two years after planting. Seedlings with a root-collar diameter of 6-8 mm and height of 60-70 cm demonstrated the best survival rates in the field. The wild cherry seedlings were shown to be highly sensitive to herbaceous weed competition early in their establishment, warranting effective weed control. When used in addition to weed control, neither intensive fertilization nor soil tillage treatments significantly increased seedling survival and growth two years after planting. Therefore, intensive site preparation, as well as fertilization, are not recommended at this stage for planting sites without severe nutrient deficiencies.

We further anchor 83.9% of scaffolds to eight chromosomes with genetic map constructed by restriction-site-associated DNA sequencing. Combining P. mume genome with available data, we succeed in reconstructing nine ancestral chromosomes of Rosaceae family, as well as depicting chromosome fusion, fission and duplication history in three major subfamilies. We sequence the transcriptome of various tissues and perform genome-wide analysis to reveal the characteristics of P. mume, including its regulation of early blooming in endodormancy, immune response against bacterial infection and biosynthesis of flower scent. The P. mume genome sequence adds to our understanding of Rosaceae evolution and provides important data for improvement of fruit trees. PMID:23271652

    Sweet cherries, Prunus avium (L.) L., grown in the western United States are exported to many countries around the world. Some of these countries have enforced strict quarantine rules and trade restrictions owing to concerns about the potential establishment and subsequent spread of western cherry fruit fly, Rhagoletis indifferens Curran (Diptera: Tephritidae), a major quarantine pest of sweet cherry. We used 1) niche models (CLIMEX and MaxEnt) to map the climatic suitability, 2) North Carolina State University-Animal and Plant Health Inspection Service Plant Pest Forecasting System to examine chilling requirement, and 3) host distribution and availability to assess the potential for establishment of R. indifferens in areas of western North America where it currently does not exist and eight current or potential fresh sweet cherry markets: Colombia, India, Indonesia, Malaysia, Taiwan, Thailand, Venezuela, and Vietnam. Results from niche models conformed well to the current distribution of R. indifferens in western North America. MaxEnt and CLIMEX models had high performance and predicted climatic suitability in some of the countries (e.g., Andean range in Colombia and Venezuela, northern and northeastern India, central Taiwan, and parts of Vietnam). However, our results showed no potential for establishment of R. indifferens in Colombia, Indonesia, Malaysia, Taiwan, Thailand, Venezuela, and Vietnam when the optimal chilling requirement to break diapause (minimum temperature < or = 3 degree C for at least 15 wk) was used as the criterion for whether establishment can occur. Furthermore, these countries have no host plant species available for R. indifferens. Our results can be used to make scientifically informed international trade decisions and negotiations by policy makers. PMID:25026662

  12. Effect of Heat Treatment of Wild Cherry Wood on Abrasion Resistance and Withdrawal Capacity of Screws

    2016-01-01

    Full Text Available In its wise use, many properties of wood are important. Among these properties, wood abrasion resistance (AR and withdrawal capacity of screws (WCS are deemed to be relatively signifi cant. It is well know that heat treatment changes the resistance features of wooden materials by changing the structural characteristics of wood. Within the scope of this study, the effects were investigated of the temperature and duration of heat treatment of Wild Cherry (Cerasus avium (L. Monench on its AR and its WCS in the radial direction and tangential direction. The test results indicated that weight loss (WL and thickness reduction (TR remained almost the same in the radial direction specimen, but there was significant TR in the tangential direction specimen. As a result of these changes, the abrasion effect of the S-42 abrader diminished based on the increase in the number of cycles. However, in both the radial and tangential direction, the WCS decreased to a significantly greater extent in the heat-treated specimens than in the control specimens.

    Many Prunus species, including sweet cherry and Japanese apricot, of the Rosaceae, display an S-RNase-based gametophytic self-incompatibility (GSI). The specificity of this outcrossing mechanism is determined by a minimum of two genes that are located in a multigene complex, termed the S locus, which controls the pistil and pollen specificities. SFB, a gene located in the S locus region, encodes an F-box protein that has appropriate S haplotype-specific variation to be the pollen determinant in the self-incompatibility reaction. This study characterizes SFBs of two self-compatible (SC) haplotypes, S(4') and S(f), of Prunus. S(4') of sweet cherry is a pollen-part mutant (PPM) that was produced by X-ray irradiation, while S(f) of Japanese apricot is a naturally occurring SC haplotype that is considered to be a PPM. DNA sequence analysis revealed defects in both SFB(4') and SFB(f). A 4 bp deletion upstream from the HVa coding region of SFB(4') causes a frame-shift that produces transcripts of a defective SFB lacking the two hypervariable regions, HVa and HVb. Similarly, the presence of a 6.8 kbp insertion in the middle of the SFB(f) coding region leads to transcripts for a defective SFB lacking the C-terminal half that contains HVa and HVb. As all reported SFBs of functional S haplotypes encode intact SFB, the fact that the partial loss-of-function mutations in SFB are present in SC mutant haplotypes of Prunus provides additional evidence that SFB is the pollen S gene in GSI in Prunus.

    Full Text Available A cross between the sweet cherry (Prunus avium cultivars 'Wanhongzhu' and 'Lapins' was performed to create a mapping population suitable for the construction of a linkage map. The specific-locus amplified fragment (SLAF sequencing technique used as a single nucleotide polymorphism (SNP discovery platform and generated 701 informative genotypic assays; these, along with 16 microsatellites (SSRs and the incompatibility (S gene, were used to build a map which comprised 8 linkage groups (LGs and covered a genetic distance of 849.0 cM. The mean inter-marker distance was 1.18 cM and there were few gaps > 5 cM in length. Marker collinearity was maintained with the established peach genomic sequence. The map was used to show that trunk diameter (TD is under the control of 4 loci, mapping to 3 different LGs. Different locus influenced TD at a varying stage of the tree's development. The high density 'W×L' genetic linkage map has the potential to enable high-resolution identification of QTLs of agronomically relevant traits, and accelerate sweet cherry breeding.

    2012-06-01

    Full Text Available Italy is one of the major users of cherry wood (Prunus avium L., and its cultivation has been increasing since the early nineties, together with studies aimed at improving genotypes, with a selection usually based on growth, stem form, vigor, and tree adaptation. Here, the phenotypic correlations between growth rate and the physical and mechanical properties of wood are investigated in two wild cherry plantations. X-ray microdensitometry was also applied to analyze the age-age correlations of wood density. It was shown that growth rate did not affect wood properties, and density was confirmed to be the trait that best represents the main properties of wood. The absence of relationships between wood density and growth rate was confirmed by densitometric analysis, although an increase of wood density with an increase of ring width was detected for very narrow rings (less than 3 mm wide. The average density at age 7 to 8 was observed to be highly correlated (r > 0.90 to the average density of a 19-year-old tree, allowing reliable estimation of the wood properties of older trees by early investigation of young trees.

    Full Text Available The studies were conducted in a nursery of sour cherry ‘Łutówka’ budded on Prunus mahaleb L. in the years 1993, 2000–2003, and 2013. The height of trees, the diameter of stems, and the length of lateral shoots were measured. The air temperature and precipitation higher than the long-term mean (by approximately 10 % and 28%, respectively contributed to the increase in the stem diameter, the total length of shoots, and the number of shoots per tree. The length of lateral shoots increased from the top of the crown towards the lower parts, however, the number of feathers per tree and the mean length of shoots decreased. A strong positive relationship (r = 0.74, P < 0.05 was revealed between the stem diameter and the total length of shoots. Generally, the correlations between the type of growth of sour cherry maiden trees and morphological traits were similar to those characteristic for apple maiden trees or “knip-boom” type trees.

    Pru av 2, a pathogenesis-related (PR) protein present in the sweet cherry (Prunus avium L.) fruit, is the principal allergen of cherry and one of the chief causes of pollen food syndrome (oral allergy syndrome). In this study, a quantitative assay for this protein was developed with the use of the protein absolute quantification (AQUA) method, which consists of liquid chromatography/tandem mass spectrometry (LC/MS/MS) employing TGC[CAM]STDASGK[(13)C6,(15)N2], a stable isotope-labelled internal standard (SIIS) peptide. This assay gave a linear relationship (r(2)>0.99) in a concentration range (2.3-600fmol/μL), and the overall coefficient of variation (CV) for multiple tests was 14.6%. Thus, the contents of this allergenic protein in sweet cherry products could be determined using this assay. This assay should be valuable for allergological investigations of Pru av 2 in sweet cherry and detection of protein contamination in foods. PMID:26988485

    The skin of developing soft and fleshy fruit is subjected to considerable growth stress, and failure of the skin is associated with impaired barrier properties in water transport and pathogen defence. The objectives were to establish a standardized, biaxial tensile test of the skin of soft and fleshy fruit and to use it to characterize and quantify mechanical properties of the sweet cherry (Prunus avium) fruit skin as a model. A segment of the exocarp (ES) comprising cuticle, epidermis, hypodermis and adhering flesh was mounted in the elastometer such that the in vivo strain was maintained. The ES was pressurized from the inner surface and the pressure and extent of associated bulging were recorded. Pressure : strain responses were almost linear up to the point of fracture, indicating that the modulus of elasticity was nearly constant. Abrading the cuticle decreased the fracture strain but had no effect on the fracture pressure. When pressure was held constant, bulging of the ES continued to increase. Strain relaxation upon releasing the pressure was complete and depended on time. Strains in longitudinal and latitudinal directions on the bulging ES did not differ significantly. Exocarp segments that released their in vivo strain before the test had higher fracture strains and lower moduli of elasticity. The results demonstrate that the cherry skin is isotropic in the tangential plane and exhibits elastic and viscoelastic behaviour. The epidermis and hypodermis, but not the cuticle, represent the structural 'backbone' in a cherry skin. This test is useful in quantifying the mechanical properties of soft and fleshy fruit of a range of species under standardized conditions. PMID:24876301

    We investigate the invariant probability measures for Cherry flows, i.e. flows on the two-torus which have a saddle, a source, and no other fixed points, closed orbits or homoclinic orbits. In the case when the saddle is dissipative or conservative we show that the only invariant probability measures are the Dirac measures at the two fixed points, and the Dirac measure at the saddle is the physical measure. In the other case we prove that there exists also an invariant probability measure supported on the quasi-minimal set, we discuss some situations when this other invariant measure is the physical measure, and conjecture that this is always the case. The main techniques used are the study of the integrability of the return time with respect to the invariant measure of the return map to a closed transversal to the flow, and the study of the close returns near the saddle.

    Full Text Available Functionality in wild cherry (Prunus avium L. clones of Tuscany Appenines provenances. Results of a research regarding the functionality of already selected wild cherry (Prunus avium L. clones are reported. The main target was to select the genotypes with the best ecological efficiency and less sensible to environmental stress, in order to give concrete indications for arboriculture for wood productions. Starting from 2002, measurements were carried out in the experimental plot of Papiano (Stia, AR, where the following clones with provenance from the Tuscan Apennines were compared: Casina Alpe 1 (A, Casina Alpe 2 (D, Puzzòlo (C, Paradisino (E, Piantata Catenaia (F. Dendrometrical data were collected at the beginning and at the end of each season, in order to evaluate the growth and the individual current increment of the clones. To better characterize the canopies of each clone, measurements of photosynthetic active radiation (PAR and of the leaf area index (LAI where carried out with ceptometers and PCA LAI 2000. In order to evaluate differences between the clones regarding functionality and response to environmental stress, growth and productivity were related to the most important canopy characteristics. Ecological efficiency was calculated for the different clones using the net assimilation rate (NAR. The results show that the clone E has the most developed canopies and the best results in terms of growth. But at the same time it also presents densely branched round canopies and results more sensible to the effects of summer drought. These elements contribute to advise against the use of this clone in future genetic improvement programs and in high quality wood productions. On the contrary, the clones C and A have both good growth characteristics and a better general architecture and are therefore advised for high quality wood productions especially in the same geographic region.

    The endophytic bacterial communities of six Prunus avium L. genotypes differing in their growth patterns during in vitro propagation were identified by culture-dependent and culture-independent methods. Five morphologically distinct isolates from tissue culture material were identified by 16S rDNA sequence analysis. To detect and analyze the uncultivable fraction of endophytic bacteria, a clone library was established from the amplified 16S rDNA of total plant extract. Bacterial diversity within the clone libraries was analyzed by amplified ribosomal rDNA restriction analysis and by sequencing a clone for each identified operational taxonomic unit. The most abundant bacterial group was Mycobacterium sp., which was identified in the clone libraries of all analyzed Prunus genotypes. Other dominant bacterial genera identified in the easy-to-propagate genotypes were Rhodopseudomonas sp. and Microbacterium sp. Thus, the community structures in the easy- and difficult-to-propagate cherry genotypes differed significantly. The bacterial genera, which were previously reported to have plant growth-promoting effects, were detected only in genotypes with high propagation success, indicating a possible positive impact of these bacteria on in vitro propagation of P. avium, which was proven in an inoculation experiment.

    为调查我省甜樱桃感染樱桃绿环斑驳病毒(Cherry Green Ring Mottle Virus,CCRMV)情况,本研究以甜樱桃(Prunus avium L.)品种“红灯”叶片总RNA为模板,根据CGRMV基因组序列设计特异引物,对山东地区37份甜樱桃“红灯”样品进行RT - PCR检测,共检测出19份阳性样品.利用CGRMV外壳蛋白基因序列引物,从阳性植物样本中分离到约800bp的目的片段,克隆测序,序列分析显示该片段全长807 bp,编码268个氨基酸,与G enBank中已登录的CGRMV分离物的外壳蛋白基因序列一致性为87% ~97%,氨基酸序列相似性为95%~99%.该结果表明山东地区甜樱桃生产园中感染CGRMV的病例较为普遍.%In order to investigate the infection of Cherry Green Ring Mottle Virus (CGRMV) from sweet cherry ( Prunus avium L. ) in Shandong province, total RNA was extracted from the leaves of the sweet cherry cultivar Red Lamp' The specific primers were designed corresponding to the CGRMV genome sequence and used for the RT - PCR detection. Thirty - seven sweet cherry samples from six orchards were analyzed in the experiment and nineteen of them were detected as positive. The gene that encodes the virus coat protein was amplified and se-quenced. Sequence analysis revealed that the fragment was 807 nucleotides in length, encoding 268 amino acids. It shared 87% ~97% identity to the other CGRMV isolates reported in GenBank in the nucleotide level and 95% ~99% similarity in the amino acids level. These results showed CGRMV had been wide spread on sweet cherry in Shandong district.

  15. Generalized Cherry oscillators and negative energy waves

    International Nuclear Information System (INIS)

    In 1925 Cherry discussed two oscillators of positive and negative energy that are nonlinearly coupled in a special way, and presented exact solutions of the nonlinear equations showing explosive instabilities independent of the strength of the nonlinearity and the initial amplitudes. In this paper Cherry's Hamiltonian is transformed into a form which allows a simple physical interpretation. The new Hamiltonian is generalized to three nonlinearly coupled oscillators; it corresponds to three-wave interaction in a continuum theory, like the Vlasov-Maxwell theory, if there exist linear negative energy waves.

    The cherry tomatoes online sorting according to their maturity is an important procedure after harvest. This research proposed an automated cherry tomato grading system base on machine vision. Three images of different angles are obtained from each cherry tomato, allowing the inspection of approximately 90% of the fruit surface. 9 features were extracted from the one cherry tomato images. In order to distinguish into three grades (immature, half ripe and ripe), Principal component analysis (PCA) and linear discrimination analysis (LDA) were used to analyze the features. The PCA results show that ripe cherry tomatoes are distinguished from immature and half ripe ones. 414 cherry tomatoes were tested by the online sorting system. The overall accuracy was up to 94.9%. Furthermore, the grading speed of the sorting line reaches 7 cherry tomatoes per second which meet the actual demand of many farms.

    A variety of phenolics had been found to be functional in promoting cellular glucose consumption that is important for blood glucose regulation. Sweet cherry (Prunus avium) is rich in such kinds of phenolics, including hydrocinnamic acids, anthocyanins, flavonols, and flavan-3-ols. Furthermore, a sweet cherry phenolics-rich extract (PRE) was found to be effective in promoting HepG2 glucose consumption. Seventeen components were preliminarily identified by HPLC-ESI-MS, including 9 hydrocinnamic acids, 4 anthocyanins, 3 flavonols, and 1 flavan-3-ol. To investigate the cellular glucose consumption-promotion activity of different phneolics subclasses, the phenolics were further fractionated into an anthocyanin-rich fraction (ARF), hydrocinnamic acid-rich fraction (HRF), and flavonol-rich fraction (FRF) through liquid-liquid extraction and mix-mode cation-exchange solid-phase extraction. The 3 fractions promoted HepG2 glucose consumption to different levels, with the promotion effects of HRF and FRF stronger than that of the ARF. The results provide guidance on the use of sweet cherry as a functional fruit. PMID:25559482

    Sweet cherry (Prunus avium) trees were manipulated to analyse the contribution of soluble sugars to sink feedback down-regulation of leaf net CO2 assimilation rate (Anet) and fruit set and quality attributes. Total soluble sugar concentration and Anet were measured in the morning on fully expanded leaves of girdled branches in two sweet cherry cultivars, 'Kordia' and 'Sylvia' characterised typically by low and high crop load, respectively. Leaves on girdled trees had higher soluble sugar concentrations and reduced Anet than leaves on non-girdled trees. Moreover, RuBP carboxylation capacity of Rubisco (Vcmax) and triose-phosphate utilisation (TPU) were repressed in the girdled treatments, despite Jmax remaining unchanged; suggesting an impairment of photosynthetic capacity in response to the girdling treatment. Leaf Anet was negatively correlated to soluble sugars, suggesting a sink feedback regulatory control of photosynthesis. Although there were significantly less fruit set and retained in 'Kordia' than 'Sylvia'; girdling had contrasting effects in each cultivar. Girdling significantly increased fruit set and fruitlet retention in 'Sylvia' cultivar, but had no effect in 'Kordia' cultivar. We propose that low inherent sink demand for photoassimilates of 'Kordia' fruit could have contributed to the low fruit retention rate, since both non-girdled and girdled trees exhibited similar retention rate and that increases in foliar carbohydrates was observed above the girdle. In 'Sylvia' cultivar, the carbohydrate status may be a limiting factor for 'Sylvia' fruit, since girdling improved both fruit set and retention, and leaf soluble solids accumulation. PMID:24189522

    2005-12-01

    Full Text Available Random amplified polymorphic DNA (RAPD analysis was performed on 38 cultivars of cherry (Prunus avium L. grown in the Jerte Valley, Cáceres, Spain. Thirty five selected decamer primers produced 69 reproducible polymorphic amplification products. The degree of polymorphism detected made possible the identification of all the cultivars by combining the RAPD banding patterns of only seven primers: OPK-08, OPQ-14, OPR-09, OPS-19, OPX-02, OPX-15 and OPZ-13. Eleven unique markers allowed identification of nine cultivars while 15 cultivars were identified by unique banding patterns. A similarity matrix derived from the RAPD amplification products generated by all the primers was obtained using the index of similarity of Jaccard. The similarity coefficients among cultivars ranged from 0.27 to 0.81 with an average of 0.50. A dendrogram based on UPGMA clustering method was constructed using the similarity matrix. The dendrogram showed a good correlation between the clustering of cherry cultivars and their geographic origin, especially revealing a stronger genetic proximity between some of the most characteristic cultivars of the Jerte Valley. This result supports the autochthonous origin hypothesis for these cultivars.

    Full Text Available Sweet cherry fruits (Prunus avium cvs. ‘Canada Giant’, ‘Ferrovia’ were harvested at commercial maturity stage and analyzed at harvest and after maintenance at room temperature (storage at ~ 20°C, shelf life for 1, 2, 4, 6 and 8 days, respectively. Fruit were initially analyzed for respiration rate, qualitative attributes and textural properties: ‘Canada Giant’ fruit were characterized by higher weight losses and stem browning index, being more intense over the late stages of shelf life period; meanwhile ‘Ferrovia’ possessed appreciably better performance even after extended shelf life period. A gradual decrease of respiration rate was monitored in both cultivars, culminated after 8 days at 20°C. The sweet cherry fruit nutraceutical profile was monitored using an array of instrumental techniques (spectrophotometric assays, HPLC, 1H-NMR. Fruit antioxidant capacity was enhanced with the progress of shelf life period, concomitant with the increased levels of total anthocyanin and of phenolic compounds. ‘Ferrovia’ fruit presented higher contents of neochlorogenic acid and p-coumarolquinic acid throughout the shelf life period. We further developed an 1H-NMR method that allows the study of primary and secondary metabolites in a single running, without previous separation and isolation procedures. Diagnostic peaks were located in the aliphatic region for sugars and organic acids, in the aromatic region for phenolic compounds and at 8.2 to 8.6 ppm for anthocyanins. This NMR-based methodology provides a unifying tool for quantitative and qualitative characterization of metabolite changes of sweet cherry fruits; it is also expected to be further exploited for monitoring temporal changes in other fleshy fruits.

    2016-02-01

    Western cherry fruit fly, Rhagoletis indifferens Curran (Diptera: Tephritidae), is a quarantine pest of sweet cherry (Prunus avium (L.) L.) that is managed using insecticides, including spinosad, an organic compound that can be applied in low spray volumes. Identifying factors that can increase the efficacy of spinosad can be useful for improving fly control. Here, the major objective was to determine if temperature mediates kill and oviposition of R. indifferens in the presence of low spinosad coverage in the laboratory. Experiments were conducted by placing flies in cages with cherries and with a Petri dish containing 3-12 small spots of dry spinosad at 18.3, 23.9, and 29.4°C. Effects of spinosad rates were also determined. More flies were killed at 23.9 and 29.4°C than at 18.3°C by 1-7 d post exposure. More flies were killed at 29.4 than 23.9°C by 1 d post exposure. However, flies laid more eggs at these temperatures than at 18.3°C. Higher spinosad rates increased kill and decreased oviposition, but even within the highest rate, oviposition was greater at 29.4 than 18.3°C. More flies walked over 5-min observation periods at 29.4 and 23.9°C than 18.3°C, suggesting higher temperatures up to 29.4°C increase kill by increasing fly contact with spinosad as well as increase oviposition rate. Results suggest that spinosad rates in sprays used against R. indifferens should be greater at higher than lower ambient temperatures. PMID:26352751

  10. Physiological and foliar symptom response in the crowns of Prunus serotina, Fraxinus americana and Acer rubrum canopy trees to ambient ozone under forest conditions

    International Nuclear Information System (INIS)

    The crowns of five canopy dominant black cherry (Prunus serotina Ehrh.), five white ash (Fraxinus americana L.), and six red maple (Acer rubrum L.) trees on naturally differing environmental conditions were accessed with scaffold towers within a mixed hardwood forest stand in central Pennsylvania. Ambient ozone concentrations, meteorological parameters, leaf gas exchange and leaf water potential were measured at the sites during the growing seasons of 1998 and 1999. Visible ozone-induced foliar injury was assessed on leaves within the upper and lower crown branches of each tree. Ambient ozone exposures were sufficient to induce typical symptoms on cherry (0-5% total affected leaf area, LAA), whereas foliar injury was not observed on ash or maple. There was a positive correlation between increasing cumulative ozone uptake (U) and increasing percent of LAA for cherry grown under drier site conditions. The lower crown leaves of cherry showed more severe foliar injury than the upper crown leaves. No significant differences in predawn leaf water potential (ψL) were detected for all three species indicating no differing soil moisture conditions across the sites. Significant variation in stomatal conductance for water vapor (gwv) was found among species, soil moisture, time of day and sample date. When comparing cumulative ozone uptake and decreased photosynthetic activity (Pn), red maple was the only species to show higher gas exchange under mesic vs. drier soil conditions (P wv and Pn demonstrate the strong influence of heterogeneous environmental conditions within forest canopies. - Within the heterogeneous environment of a mature forest, many factors in addition to soil moisture play a significant role in determining exposure/response relationships to ozone

    This study characterises a series of 12 S-locus haplotype-specific F-box protein genes (SFB) in cherry (Prunus avium) that are likely candidates for the pollen component of gametophytic self-incompatibility in this species. Primers were designed to amplify 12 SFB alleles,including the introns present in the 50 untranslated region;sequences representing the S-alleles S1, S2, S3, S4, S40, S5,S6, S7, S10, S12, S13 and S16 were cloned and characterized. [The nucleotide sequences reported in this paper have been submitted to the EMBL/GenBank database under the following accession numbers: PaSFB1(AY805048), PaSFB2 (AY805049), PaSFB3 (AY805057),PaSFB4 (AY649872), PaSFB40 (AY649873), PaSFB5(AY805050), PaSFB6 (AY805051), PaSFB7 (AY805052),PaSFB10 (AY805053), PaSFB12 (AY805054), PaSFB13(AY805055), PaSFB16 (AY805056).] Though the coding regions of six of these alleles have been reported previously,the intron sequence has previously been reported only for S6. Analysis of the introns revealed sequence and length polymorphisms. A novel, PCR-based method to genotype cultivars and wild accessions was developed which combines fluorescently labelled primers amplifying the intron of SFB with similar primers for the first intron of S-RNase alleles. Intron length polymorphisms were then ascertained using a semi-automated sequencer. The convenience and reliability of this method for the determination of the self-incompatibility (SI) genotype was demonstrated both in sweet cherry cultivars representing alleles S1 to S16 and in individuals from a wild population encompassing S-alleles S17 to S22. This method will greatly expedite SI characterisation in sweet cherry and also facilitate large-scale studies of self-incompatibility in wild cherry and other Prunus populations.

    Two plant-tumorigenic strains KFB 330(T) and KFB 335 isolated from galls on raspberry (Rubus idaeus) in Serbia, and a non-pathogenic strain AL51.1 recovered from a cherry plum (Prunus cerasifera) tumor in Poland, were genotypically and phenotypically characterized. Phylogenetic reconstruction based on 16S rDNA placed them within the genus Agrobacterium, with A. nepotum as their closest relative. Multilocus sequence analysis (MLSA) based on the partial sequences of atpD, glnA, gyrB, recA and rpoB housekeeping genes suggested that these three strains represent a new Agrobacterium species, that clustered with type strains of A. nepotum, A. radiobacter, "A. fabrum" and A. pusense. This was further supported by average nucleotide identity values (<92%) between the whole genome sequences of strain KFB 330(T) and related Agrobacterium species. The major cellular fatty acids of the novel strains were 18:1 w7c (72.8-77.87%) and 16:0 (6.82-8.58%). Phenotypic features allowed their differentiation from closely related species. Polyphasic characterization showed that the three strains represent a novel species of the genus Agrobacterium, for which the name Agrobacterium arsenijevicii sp. nov. is proposed. The type strain of A. arsenijevicii is KFB 330(T) (= CFBP 8308(T) = LMG 28674(T)).

    Full Text Available Greenhouse tomato cultivation plays an important role in Sicily, being the primary production area in Italy, due to its favorable pedo-climatic conditions that permit extra-seasonal productions. In Sicily, more than half of greenhouse tomato production is derived from the Province of Ragusa on the southeastern coast, where especially cherry tomato typologies are cultivated. Over the last decade, the Ragusa Province has registered a decrease both in terms of greenhouse tomato area and harvested production due to several structural problems that would require restructuring of the tomato supply chain. Thus, since recognition of real costs and profitability of tomato growing is a vital issue, both from the perspective of the farm, as well as from that of the entrepreneur, the aim of this paper was to analyze the economic sustainability of Sicilian greenhouse cherry tomato cultivated in the Ragusa Province. In particular, an economic analysis on 30 representative farms was conducted in order to estimate production costs and profits of greenhouse cherry tomato. According to our results, the lack of commercial organization, which characterizes the small farms we surveyed, determines low contractual power for farmers and, consequently, low profitability.

    Full Text Available Biodiversity of natural populations, biodiversity located on farm and the introduced cultivars and selections are a rich source of genetic variability in sour and sweet cherries, but they have never been bread with the aim of creating decorative varieties. Low vigour − dwarfing and upright − sour cherry genotypes, NS 1/16 KK and NS 1/24 KK, were selected from natural population of Fruška Gora and private arboretum, respectively. Sweet cherry selections NS 6/15 K and RŠ 8/27 were part of on farm conservation of genetic resources. Furthermore, reduction in vigour was achieved by defining specific combining abilities as a result of rootstock/scion interaction. The outcome of this study is unique columnar and dwarf forms that integrate specific genetic potential of varieties and selections, their interaction with rootstocks and traditional horticultural skills. Collected biodiversity is another confirmation that the Balkan peninsula is one of the most valuable secondary centres of genetic diversity and inexhaustible gene pool for breeding both, varieties and vegetative rootstocks.

    The present study investigated the genetic determinism of flowering date (FD), dissected into chilling (CR) and heat (HR) requirements. Elucidation of the genetic determinism of flowering traits is crucial to anticipate the increasing of ecological misalignment of adaptative traits with novel climate conditions in most temperate-fruit species. CR and HR were evaluated over 3 yr and FD over 5 yr in an intraspecific sweet cherry (Prunus avium) F1 progeny, and FD over 6 yr in a different F1 progeny. One quantitative trait locus (QTL) with major effect and high stability between years of evaluation was detected for CR and FD in the same region of linkage group (LG) 4. For HR, no stable QTL was detected. Candidate genes underlying the major QTL on LG4 were investigated and key genes were identified for CR and FD. Phenotypic dissection of FD and year repetitions allowed us to identify CR as the high heritable component of FD and a high genotype × environment interaction for HR. QTLs for CR reported in this study are the first described in this species. Our results provide a foundation for the identification of genes involved in CR and FD in sweet cherry which could be used to develop ideotypes adapted to future climatic conditions. PMID:24417538

    The genus Phaeoacremonium is associated with opportunistic human infections, as well as stunted growth and die-back of various woody hosts, especially grapevines. In this study, Phaeoacremonium species were isolated from necrotic woody tissue of Prunus spp. (plum, peach, nectarine and apricot) from different stone fruit growing areas in South Africa. Morphological and cultural characteristics as well as DNA sequence data (5.8S rDNA, ITS1, ITS2, beta-tubulin, actin and 18S rDNA) were used to identify known, and describe novel species. From the total number of wood samples collected (257), 42 Phaeoacremonium isolates were obtained, from which 14 species were identified. Phaeoacremonium scolyti was most frequently isolated, and present on all Prunus species sampled, followed by Togninia minima (anamorph: Pm. aleophilum) and Pm. australiense. Almost all taxa isolated represent new records on Prunus. Furthermore, Pm. australiense,Pm. iranianum, T. fraxinopennsylvanica and Pm. griseorubrum represent new records for South Africa, while Pm. griseorubrum, hitherto only known from humans, is newly reported from a plant host. Five species are newly described, two of which produce a Togninia sexual state. Togninia africana, T. griseo-olivacea and Pm. pallidum are newly described from Prunus armeniaca, while Pm. prunicolum and Pm. fuscum are described from Prunus salicina.

  8. Single amino acid changes in the 6K1-CI region can promote the alternative adaptation of Prunus- and Nicotiana-propagated Plum pox virus C isolates to either host.

    2014-02-01

    Plum pox virus (PPV) C is one of the less common PPV strains and specifically infects cherry trees in nature. Making use of two PPV-C isolates that display different pathogenicity features, i.e., SwCMp, which had been adapted to Nicotiana species, and BY101, which had been isolated from cherry rootstock L2 (Prunus lannesiana) and propagated only in cherry species, we have generated two infective full-length cDNA clones in order to determine which viral factors are involved in the adaptation to each host. According to our results, the C-P3(PIPO)/6K1/N-CI (cylindrical inclusion) region contains overlapping but not coincident viral determinants involved in symptoms development, local viral amplification, and systemic movement capacity. Amino acid changes in this region promoting the adaptation to N. benthamiana or P. avium have trade-off effects in the alternative host. In both cases, adaptation can be achieved through single amino acid changes in the NIapro protease recognition motif between 6K1 and CI or in nearby sequences. Thus, we hypothesize that the potyvirus polyprotein processing could depend on specific host factors and the adaptation of PPV-C isolates to particular hosts relies on a fine regulation of the proteolytic cleavage of the 6K1-CI junction.

    Many species in the Rosaceae, the Solanaceae, and the Plantaginaceae exhibit S-RNase-based gametophytic self-incompatibility (GSI). This system comprises S-ribonucleases (S-RNases) as the pistil S determinant and a single or multiple F-box proteins as the pollen S determinants. In Prunus, pollen specificity is determined by a single S haplotype-specific F-box protein (SFB). The results of several studies suggested that SFB exerts cognate S-RNase cytotoxicity, and a hypothetical general inhibitor (GI) is assumed to detoxify S-RNases in non-specific manner unless it is affected by SFB. Although the identity of the GI is unknown, phylogenetic and evolutionary analyses have indicated that S locus F-box like 1-3 (or S locus F-box with low allelic sequence polymorphism 1-3; SLFL1-3), which are encoded by a region of the Prunus genome linked to the S locus, are good GI candidates. Here, we examined the biochemical characteristics of SLFL1-3 to determine whether they have appropriate GI characteristics. Pull-down assays and quantitative expression analyses indicated that Prunus avium SLFL1-3 mainly formed a canonical SCF complex with PavSSK1 and PavCul1A. Binding assays with PavS(1,3,4,6)-RNases showed that PavSLFL1, PavSLFL2, and PavSLFL3 bound to PavS(3)-RNase, all PavS-RNases tested, and none of the PavS-RNases tested, respectively. Together, these results suggested that SLFL2 has the appropriate characteristics to be the GI in sweet cherry pollen, while SLFL1 may redundantly work with SLFL2 to detoxify all S-RNases. We discuss the possible roles of SLFL1-3 as the GI in the Prunus-specific S-RNase-based GSI mechanism. PMID:27071402

    Precision regulated deficit irrigation scheduling is useful for improving water productivity and ensuring crop production sustainability. This form of water management requires continuous monitoring in order to know soil and/or plant water status at all times. Water status sensors are key tools for modulating irrigation water amounts. The objective of this work was to study the physiological and agronomic response of cherry trees to different irrigation treatments based on crop evapotranspiration (ETc). However, the final purpose was to establish threshold values of water stress indicators, which can be considered of practical applicability in automatic irrigation scheduling. The experiment was carried out in 2015 in a 0.5 ha commercial plot of 'Prime Giant' cherry [Prunus avium (L.)] in SE Spain. Three treatments were studied i) T110, irrigated above the maximum crop water requirements (110% of ETc), ii) T85, sustained deficit irrigation, irrigated to satisfy 85% of ETc, throughout the growing season, and iii) T100-55, regulated deficit irrigation with different water deficit levels: 100% and 55% of ETc during pre- and postharvest, respectively. Each treatment was randomly distributed in blocks and run in triplicate. Soil and plant water status were assessed from the soil matric potential and volumetric water content (Ym and Ov), midday stem and fruit water potential (Ys and Yf), maximum daily trunk shrinkage (MDS), daily trunk growth rate (TGR), stomatal conductance (gs), photosynthesis (Pn) and transpiration rates (E). Vegetative growth, yield and the quality of the fruit were also evaluated. Ys and MDS signal intensity were used as the main indicators of water stress. The water applied during the 2015 growing season was 7190, 5425 and 4225 m3 ha-1 for T110, T85 and T100-55, respectively. The mean values of Ys during pre- and postharvest were -0.51, -0.57, -0.54 and -0.65, -0.77 and -0.97 MPa in T110, T85 and T100-55, respectively, while Yf was -1.20, -1.36, -1

    Wilkins, D.; Oosten, J.-J. van; Besford, R.T. (Horticulture Research International, Littlehampton, Sussex (United Kingdom))

    1994-01-01

    A study was conducted of the growth response of Prunus avium L. Stella (wild cherry) to elevated CO[sub 2]. The associated changes in photosynthetic machinery of the leaf tissue were characterized. Self-pollinated seedlings and mature cuttings (clones) from the same parent plant of P. avium were grown for two consecutive growing seasons (about 60 days each) in ambient or elevated CO[sub 2] with high or low nutrient supply. The degree of acclimation of leaf biochemistry and growth response to elevated CO[sub 2] depended on the plant material (seedling or mature cutting) and nutrient supply. There was little or no growth response to elevated CO[sub 2] in seedlings or cuttings in the low nutrient supply treatments, whereas in both seasons, there was a strongly positive growth response to elevated CO[sub 2] in seedlings and cuttings in the high nutrient supply regimes, resulting in increases in the root/shoot ratio and in carbon allocation to the roots. In contrast, the protein content and activity of ribulose-1,5-biophosphate carboxylase-oxygenase (Rubisco, EC 4.1.1.39) were down regulated in elevated CO[sub 2]. The loss of Rubisco on an area basis in plants in the elevated CO[sub 2] treatments was compensated for at the canopy level by increased leaf area. The loss of Rubisco protein was accompanied by decreases in the contents of chlorophyll and the thylakoid membrane proteins D[sub 1], D[sub 2] and cytochrome f, which are involved in light harvesting and photo-electron transport. It is concluded that in the medium- to long-term, the initial stimulation of biomass production by elevated CO[sub 2] may be increasingly offset by a lower photosynthetic capacity per unit leaf area in perennial plants. 27 refs., 2 figs., 3 tabs.

    Full Text Available Rain-induced cracking before harvest is the major cause of crop loss in sweet cherry (Prunus avium [L.] L. In order to better understand the relationship between cherry fruit cracking and gene expression, the transcriptional patterns of six genes related to cell wall modification and cuticular wax biosynthesis were analyzed during fruit setting (FS, fruit color change (FC and fruit ripening (FR, employing two contrasting cultivars: the cracking resistant 'Kordia' and the cracking susceptible 'Bing'. The transcription levels of AP2/EREBP-type transcription factor (PaWINB, wax synthase (WS, ß-ketoacyl-CoA synthase (PaKCS6, and ß-galactosidase (ß-Gal showed higher levels in 'Kordia' than in 'Bing' during the FS stage, while similar values were observed in both cultivars at FR stage. In contrast to that pattern, transcription levels of expansin (PaEXPl were higher at FR stage in 'Kordia' than in 'Bing'. Transcript profile of lipid transport protein gene (PaLTPGl decreased during fruit development, with higher levels in 'Bing' than in 'Kordia' at FC and FR stages suggesting no relation with cracking tolerance. The expression profiles of PaWINB, WS, PaKCS6, and ß-Gal suggest that they are genes involved in conferring cracking tolerance, likely due to their function in cuticle deposition during early stages of fruit development. In addition, a greater expression level of expansin gene would allow for a faster growth rate in 'Kordia' at FR stage.

  19. A 280-Year Long Series of Phenological Observations of Cherry Tree Blossoming Dates for Switzerland

    Rutishauser, T.; Luterbacher, J.; Wanner, H.

    2003-04-01

    Phenology is generally described as the timing of life cycle phases or activities of plants and animals in their temporal occurrence throughout the year (Lieth 1974). Recent studies have shown that meteorological and climatological impacts leave their 'fingerprints' across natural systems in general and strongly influence the seasonal activities of single animal and plant species. During the 20th century, phenological observation networks have been established around the world to document and analyze the influence of the globally changing climate to plants and wildlife. This work presents a first attempt of a unique 280-year long series of phenological observations of cherry tree blossoming dates for the Swiss plateau region. In Switzerland, a nation-wide phenological observation network has been established in 1951 currently documenting 69 phenophases of 26 different plant species. A guidebook seeks to increase objectiveness in the network observations. The observations of the blooming of the cherry tree (prunus avium) were chosen to calculate a mean series for the Swiss plateau region with observations from altitudes ranging between 370 and 860 asl. A total number of 737 observations from 21 stations were used. A linear regression was established between the mean blooming date and altitude in order to correct the data to a reference altitude level. Other ecological parameters were unaccounted for. The selected network data series from 1951 to 2000 was combined and prolonged with observations from various sources back to 1721.

    Genetic diversity strongly influences populations' adaptability to changing environments and therefore survival. Sustainable forest management practices have multiple roles including conservation of genetic resources and timber production. In this study, we aimed at better understanding the variation in genetic diversity among adult and offspring individuals, and the effects of mating system on offspring survival and growth in wild cherry, Prunus avium. We analysed adult trees and open pollinated seed-families from three stands in Germany at eight microsatellite loci and one incompatibility system locus and conducted paternity analyses. Seed viability testing and seed sowing in a nursery allowed further testing for the effects of pollen donor diversity and genetic similarity between mates on the offspring performance at the seed and seedling stages. Our results were contrasting across stands. Loss of genetic diversity from adult to seedling stages and positive effect of mate diversity on offspring performance occurred in one stand only, whereas biparental inbreeding depression and significant decrease in fixation index from adults to seedlings was detected in two stands. We discussed the effects of stand genetic diversity on the magnitude of biparental inbreeding depression at several life-stages and its consequences on the management of genetic resources in P. avium.

    We investigated the effect of leaf age on the response of net photosynthesis (A), stomatal conductance (g{sub wv}), foliar injury, and leaf nitrogen concentration (N{sub L}) to tropospheric ozone (O{sub 3}) on Prunus serotina seedlings grown in open-plots (AA) and open-top chambers, supplied with either carbon-filtered or non-filtered air. We found significant variation in A, g{sub wv}, foliar injury, and N{sub L} (P < 0.05) among O{sub 3} treatments. Seedlings in AA showed the highest A and g{sub wv} due to relatively low vapor pressure deficit (VPD). Older leaves showed significantly lower A, g{sub wv}, N{sub L}, and higher foliar injury (P < 0.001) than younger leaves. Leaf age affected the response of A, g{sub wv}, and foliar injury to O{sub 3}. Both VPD and N{sub L} had a strong influence on leaf gas exchange. Foliar O{sub 3}-induced injury appeared when cumulative O{sub 3} uptake reached 8-12 mmol m{sup -2}, depending on soil water availability. The mechanistic assessment of O{sub 3}-induced injury is a valuable approach for a biologically relevant O{sub 3} risk assessment for forest trees. - Ozone effects on symptom development and leaf gas exchange interacted with leaf age and N-content on black cherry seedlings.

    Cherry virus A(CVA) is a member of the genusCapilovirus, in the familyBetalfexiviridae. The infection rate of CVA was high in sweet cherry in China. We determined the complete nucleotide sequences of two isolates of CVA from Tai’an, Shan-dong Province, China using high ifdelity PCR enzymes and speciifc primer pairs for amplifying long fragments in RT-PCR and RACE. The ful-length sequences from isolates ChTA11 and ChTA12 are both 7382 nucleotide (nt) long, excluding the poly(A) tail, encode two open reading frames (ORFs) and have similar genome organization to the two isolates in Gen-Bank. The complete nucleotide sequence of ChTA11 is 98.2 and 81.2% nt identity to the isolates from Germany and India in GenBank, respectively, and the ChTA12 isolate is 98.2 and 81.0% similar. Analysis of the nucleotide and amino acid sequences showed that the domain of unknown function (DUF1717) is more variable compared with other domains. This is the ifrst report of the complete nucleotide sequences of CVA isolates infecting sweet cherry in China.

    Full Text Available Abstract Background Prunus yedoensis Matsum. is used as traditional medicine—‘Yaeng-Pi’ or ‘Hua-Pi’—in Japan and Korea. However, no studies have examined the pharmacological activities of the P. yedoensis bark. Only the antioxidant and antiviral activities of P. yedoensis fruit and the anti-hyperglycaemic effect of P. yedoensis leaf have been investigated. While studying the antihypertensive effects of several medicinal plants, we found that a methanol extract of P. yedoensis bark (MEPY had distinct vasorelaxant effects on rat aortic rings. Methods The aortic rings were removed from Sprague–Dawley rats and suspended in organ chambers containing 10 ml Krebs-Henseleit solution. The aortic rings were placed between 2 tungsten stirrups and connected to an isometric force transducer. Changes in tension were recorded via isometric transducers connected to a data acquisition system. Results MEPY relaxed the contraction induced by phenylephrine (PE both in endothelium-intact and endothelium-denuded aortic rings concentration dependently. However, the vasorelaxant effects of MEPY on endothelium-denuded aortic rings were lower than endothelium-intact aortic rings. The vasorelaxant effects of MEPY on endothelium-intact aortic rings were reduced by pre-treatment with l-NAME, methylene blue, or ODQ. However, pre-treatment with indomethacin, atropine, glibenclamide, tetraethylammonium, or 4-aminopyridine had no affection. In addition, MEPY inhibited the contraction induced by extracellular Ca2+ in endothelium-denuded rat thoracic aorta rings pre-contracted by PE (1 μM or KCl (60 mM in Ca2+-free solution. Conclusions Our results suggest that MEPY exerts its vasorelaxant effects via the activation of NO formation by means of l-Arg and NO-cGMP pathways and via the blockage of extracellular Ca2+ channels.

    Diabetes mellitus (DM) is a metabolic disorder in the endocrine system resulting from a defect in insulin secretion, insulin action or both of them. Adverse side effects of chemical drugs for treatment of diabetes persuaded the using of medical plants. Cherry as a traditionally used plant for treatment of diabetes, is packed with powerful plant pigments called anthocyanins. They give cherries their dark red color and are one of the richest antioxidant sources which lower the blood sugar and bear other beneficial health effects. The purpose of this study is to evaluate the effect of ethanolic extract of cherry fruit on alloxan induced diabetic rats. In this study 36 Male Wistar rats, body weight of 150-200gr were divided into 6 groups. Diabetes was induced by intra peritoneal injection of 120 mg/kg Alloxan. The duration of the cherries treatment was 30 days in which single dose of extracts (200mg/kg) were oral administered to diabetic rats. Blood glucose levels were estimated with glucometer before treatment, 2h and 1- 4 weeks after administration of extracts. Treatment with extracts of the cherries resulted in a significant reduction in blood glucose and urinary microalbumin and an increase in the creatinine secretion level in urea. Extract of this plant is useful in controlling the blood glucose level. Cherries appear to aid in diabetes control and diminution of the complications of the disease. Some relevant patents are also outlined in this article. PMID:22280223

    Full Text Available The objective of this study was to compare Rosaceae genotypes from for their pollen viability and morphology. The pollen of some varieties of Malus domestica, Pyrus communis, Prunus domestica, Prunus persica and Prunus armeniaca was identified. Pollen from mature anthers was collected. Pollen grains of all genera of Rosaceae surveyed occur as radially symmetric isopolar monads. The main aspect studied were the shape of pollen in the polar view (polar perimeter and polar area of pollen. Shape of pollen is triangular-obtuse-convex in polar view. The pollen class is trizonocolpate-obtus-triangular while the sculpturing of exine surface is striate. The number of colpi is three while the spines are absent. Apart from fully developed pollen grains, also much smaller, not completely developed pollen were found in the samples of the examined species. The viability of the pollen was determined on 1% 2,3,5-triphenyl tetrazolium chloride (TTC. Viable, semi-viable and dead pollen numbers and their percentages were determined. This stain test may be used to determine pollen viability in these species to provide only a rough estimate of viability. The results presented here are important for improving our understanding of Rosaceae reproduction biology. Knowledge of reproduction biology, particularly pollen viability and quality, is critical for the newly-developed cultivars.

    In recent times, plums have been described as foods with health-promoting properties. Research on the health effects of plum continue to show promising results on its antiinflammatory, antioxidant and memory-improving characteristics. The increased interest in plum research has been attributed to its high phenolic content, mostly the anthocyanins, which are known to be natural antioxidants. A systematic review of literature was carried out to summarize the available evidence on the impact of plums (Prunus species; domestica and salicina) on disease risk factors and health outcomes. A number of databases were searched according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for relevant studies on plum health effects in vitro, animal studies and clinical trials. A total of 73 relevant peer-reviewed journal articles were included in this review. The level of evidence remains low. Of the 25 human studies, 6 were confirmatory studies of moderate quality, while 19 were exploratory. Plums have been shown to possess antioxidant and antiallergic properties, and consumption is associated with improved cognitive function, bone health parameters and cardiovascular risk factors. Most of the human trials used the dried version of plums rather than fresh fruit, thus limiting translation to dietary messages of the positioning of plums in a healthy diet. Evidence on the health effect of plums has not been extensively studied, and the available evidence needs further confirmation. Copyright © 2016 John Wiley & Sons, Ltd. PMID:26992121

Cv. Tieton and cv. Summit) were held into controlling atmosphere box (CAB), and then stored at (0 ± 0.5)t. The postharvest qualities of sweet cherry fruit were investigated at interval. Results showed that the carbon dioxide concentration in CAB were 12%-15%, and 6% higher O2 concentration. Firmness in fruit stored in CAB was higher than those in control. CAB treatment decreased the soluble solids content of sweet cherry fruit, but maintained the higher tritratable acidity and Vc content in contrast to control. CAB treatment inhibited significantly the decay incidence of sweet cherry fruit during storage and shelf-life. The lower decay incidence was found in 'Summit' fruit compared with 'Tieton' fruit. The sweet cherry fruit treated by CAB still had good sensory quality significantly after 60 days of storage and 3 days of shelf-life at ambient temperature. In general, CAB can keep better qualities, and be suitable for transportation and sales industry of sweet cherry fruit.

    10 samples of fresh-frozen cornelian cherry fruits (Cornus mas L.), collected in the Tambov and the Caucasus regions, were investigated for the total amount and composition of the main biologically active substances (BAS): anthocyanins (AC), proanthocyanidins (OPC), dihydroxycinnamic acids (DHCA), iridoids, organic acids, mono- and disaccharides and antiradical activity in the DPPH-test in vitro. Total phenolics content determined by Folin-Ciocalteu method, was 150-400 mg/100 g fresh fruit weight. The OPC content, estimated by Bate-Smith method, varied from 20-25 mg/100 g of unripe cornelian cherries to 80-430 mg/100 g of mature cornelian cherries. Total AC amount evaluated by pH-differential spectrophotometry was minimal in unripe fruits (11,2 mg/100 g), and maximal in mature fruits (92,2 mg/100 g). Profile of individual AC was determined by HPLC with UV/Vis and ESI-TOF-MS detections. 3-galactosides of cyanidin (19,0-80,3%) and pelargonidin (15,1-75,6%) were found as main anthocyanins. An original methodology for iridoid determination based on HPLC with UV and ESI-TOF-MS detection was developed. The main iridoids were identified as loganic acid, loganin, sweroside and cornuside. Total iridoids content was 130-400 mg/100 g, and loganic acid was predominant in all samples (87,6-94,8%). Only minor amount of the DHCA derivatives (cherries was represented by fructose (2,2-3,8%) and glucose (2,5-7,0%). 70% water-ethanol extracts of Cornus mas fruits have showed pronounced antiradical activity in DPPH-test (470,5-932,0 mg TE/100 g). The data on specific minor BAS can be used in the standardization and evaluation of potential biological activity of extracts and dietary supplements based on the cornelian cherry fruits.

    This paper is concerned on the relation of bud dormancy to carbohydrate metabolism, The annual shoots from underground stem was used as the experimental materials. The components of carbohydrates and the enzymes activities were measured in phloem and bud of dormant Cerasus humilis (Bge.) Sok. The results indicated that soluble sugar content was higher than starch in phloem and bud in dormancy period. The highest ratio of soluble sugar and starch reached to 4.77. Most sugar was sucrose and then fructose, sorbitol and glucose. A few amount of fructose in bud were detected in natural dormancy stage. But its content increased rapidly in enhanced dormancy stage and in germination period,reaching to 2.05% in germination period. The changes in enzyme activities in phloem and bud were in line with that of soluble sugar. The activity of SPS was higher than that of other enzymes, but quickly decreased in natural dormancy stage,and reached to minimum at the end of the natural dormancy. The reduction in bud and phloem was 94. 18% and 84.78% respectively. The activity of p-amylase was higher that of a-amylase. Based on the integrated analyses above,the main accumulated carbohydrate in dormant Chinese dwarf cherry was soluble sugar. The relief of natural dormancy was obviously linked with the change of sucrose and reduction of the SPS activity. Change in the fructose contents was related to the dormancy and germination of bud.%为探讨休眠期欧李碳水化合物代谢与休眠的关系,以休眠期欧李1年生基生枝为试材,采用气相色谱等方法,分析了韧皮部、芽中碳水化合物含量及其相关酶活性变化。结果表明:休眠阶段欧李韧皮部和芽中可溶性糖含量均高于淀粉,二者比值最高可达4.77,其中含量最高的为蔗糖,其次是果糖、山梨醇和葡萄糖;自然休眠期芽中检查不到果糖含量,但在被迫休眠期和芽萌动期迅速增加,至芽萌动期质量分数达2.05%;休眠期韧皮部和芽中

    2000-04-01

    The occurrence and formation of ochratoxin A (OTA) in Robusta coffee was studied for three consecutive seasons under tropical conditions in Thailand. Sun drying of coffee cherries consistently led to OTA formation in the pulp and parchment (husks) of the cherries. In replicated trials, dried coffee beans (green coffee) were shown to contain on average OTA concentrations that were approximately 1% of those found in husks. OTA contamination of green coffee depended on cherry maturity, with green cherries being the least, and overripe cherries the most susceptible. Defects, and in particular the inclusion of husks, are the most important source of OTA contamination. OTA contamination occurred independently of whether cherries were placed on concrete, on bamboo tables, or on the ground. The study suggests that better raw material quality, an appropriate drying and dehulling procedure combined with a reduction of green coffee defects can effectively contribute to the reduction of OTA in green coffee.

    In order to grope for the mechanism in fruiting problem of sweet cherryPrunus avium L. ) in southern areas of China, three experiments, including variety comparison, location comparison and artifi- cial environmental simulation, had been carried out from the stage of post-defoliation to the stage of post- bloom for observation of the characteristics of differentiation and development of floral bud of sweet cherry. The results showed that the floral bud of sweet cherry had ultimately displayed the basic characteristics of differentiation and development in identity at the phases of multi-phenological calendars in the stages mentioned above in those tested varieties which were Zaohongbaoshi, Hongdeng and Lapins cultured in Zhengzhou, and Hongdeng cultured in Yantai, Zhengzhou, and Jinhua, and Zaohongbaoshi cultured in openfield and greenhouse in the period of floral bud differentiation in those three experimental designs. It was argued that the mechanism of fruiting difficulty mentioned above had no relationship with the floral bud differentiation in growth season, and not only the embryo sac in poorly developmental quality which was induced by high temperature before the stage of post-bloom but laso the shortage of chilling accumu- lation should be responsible for the fruiting difficulty.%通过品种比较、地区比较和人工环境模拟3个关联的试验设计,观察甜樱桃从落叶后至谢花后的花芽分化发育的特征,探求其南引试栽、结实困难的原因。结果表明,郑州的早红宝石、红灯和拉宾斯.烟台、郑州和金华的红灯,以及花芽分化期置于露地和日光温室中的早红宝石在多个物候期阶段的最终分化发育的基本特征一致。因此。造成甜樱桃南引试栽、结实困难的主要原因可能与生长季的花芽分化无关,不能仅限于与花前高温引发的胚珠、胚囊发育不良有关,低温累积量不足也是不可被忽视的因素。

    A novel phytoplasma was detected in a cherry plum (Prunus cerasifera Ehrh) tree that mainly showed yellow leaf symptom. The tree was growing in an orchard located in Yangling District, Shaanxi Province, China. The leaves started as chlorotic and yellowing along leaf minor veins and leaf tips. Chlorosis rapidly developed to inter-veinal areas with the whole leaf becoming pale yellow in about 1-4 wk. Large numbers of phytoplasma-like bodies (PLBs) were seen under transmission electron microscopy. The majority of the PLBs was spherical or elliptical vesicles, with diameters in range of 0.1-0.6 µm, and distributed in the phloem cells of the infected tissues. A 1 246-bp 16S ribosomal RNA (rRNA) gene fragment was ampliifed from DNA samples extracted from the yellow leaf tissues using two phytoplasma universal primer pairs R16mF2/R16mR1 and R16F2n/R16R2. Phylogenetic analysis using the 16S rRNA gene sequence suggested that the phytoplasma associated with the yellow leaf symptoms belongs to a novel subclade in the aster yellows (AY) group (16SrI group). Virtual and actual restriction fragment length polymorphism (RFLP) analysis of the 16S rRNA gene fragment revealed that the phytoplasma was distinguishable from all existing 19 subgroups in the AY group (16SrI) by four restriction sites, Hinf I, Mse I, Sau3A I and Taq I. The similarity coefifcients of comparing the RFLP pattern of the 16S rRNA gene fragment of this phytoplasma to each of the 19 reported subgroups ranged from 0.73 to 0.87, which indicates the phytoplasma associated with the cherry plum yellow leaf (CPYL) symptoms is probably a distinct and novel subgroup lineage in the AY group (16SrI). In addition, the novel phytoplasma was experimentally transmitted to periwinkle (Catharanthus roseus) plants from the tree with CPYL symptoms and then back to a healthy 1-yr-old cherry plum tree via dodder (Cuscuta odorata) connections.

    Full Text Available Plum is a globally grown stone fruit and can be divided into several species. In particular, the Prunus salicina, which is native to China, is widely grown in many fruit orchards in Korea and Japan, as well as the United States and Australia. The transcriptome data for Prunus salicina has not been reported to our knowledge. In this study, we performed de novo transcriptome assembly for two selected P. salicina cultivars referred to as Akihime and Formosa (commercially important plum cultivars in Korea using next generation sequencing. We obtained a total of 9.04 GB and 8.68 GB raw data from Akihime and Formosa, respectively. De novo transcriptome assembly using Trinity revealed 155,169 and 160,186 transcripts for Akihime and Formosa. Next, we identified 121,278 and 116,544 proteins from Akihime and Formosa using TransDecoder. We performed BLASTP against the NCBI non-redundant (nr dataset to annotate proteins. Taken together, this is the first transcriptome data for P. salicina to our knowledge.

    Genetic relationships among Prunus mume var. pendula were studied by using AFLP markers. 18 accessions representing 14 cultivars ofPrunus murne var. pendula were selected from the germplasm collection at the Research Center of China Mci Flower. Seven Mse I-EcoR I AFLP primer combinations revealed 450 legible bands, and 269 of which were polymorphic markers. A similarity matrix was prepared using the simple matching coefficient of similarity and Nei's (72) distance coefficient. A UPGMA dendrogram demonstrated the genetic relationships of the cultivars. The information given by AFLP markers was basically consistent with the morphological classification and the evolutionary history of the morphotypes, and roughly supported the new revised classification system for Chinese Mci Cultivars. But there were still several exceptions: 1) the 'Guhong Chuizhi' inserted between the 'Tiaoxue Chuizhi' and the 'Danfen Chuizhi'; 2) the 'Wufu Chuizhi' kept off the Pink Pendant Form, and the 'Moshan Chuizhi' was removed from Viridiflora Pendant Form; 3) the 'Danbi Chuizhi' and the 'Shuangbi Chuizhi' of Viridiflora Pendant Form got together well but fell within the Pink Pendant Form.

    [Objective] The relationship between polymorphism of DFR gene and pericarp colors was studied in 70 sweet cherry varieties. [Method] DNA sequences analysis was applied to detect the polymorphism of DFR gene in 10 sweet cherry varieties (Prunus avium L.) of different colors in pericarp. Special primers were designed to amplify the polymorphic DNA fragments. 70 sweet cherry varieties (P. Avium L.) were used to test DFR gene polymorphism. [Result] The DNA sequences of partial DFR gene about 1 kb were obtained from sweet cherry (P. Avium). The identity of these DNA sequences was 80% with DFR gene of peach (Prunus persica). The identity of predicted amino acid sequences was 99% with the amino acid sequence of DFR in sweet cherry. This partial DFR gene contained 3 extrons and 3 introns. Two polymorphic loci were detected in intron 2 and intron 3. Three haplotypes and five haplotype combinations were found among 70 sweet cherry varieties which are composed of yellow pericarp group, yellow with a pink blush pericarp group and red pericarp group. There was no significant difference in the DFR gene frequencies between yellow with a pink blush pericarp group and dark red pericarp group. [Conclusion] Two polymorphism loci were detected in intron 2 and intron 3 of DFR gene. Preponderatn alleles frequencies of 70 sweet cherry varieties was 0.864 in intron 2 and 0.679 in intron 3.

    2014-10-01

    To improve storage/shipping quality of sweet cherry (Prunus avium L.), the effect of calcium chloride (CaCl2) added to hydro-cooling water on physiological and biochemical processes related to fruit and pedicel quality was investigated on two major cultivars. The fruit tissue Ca content increased up to 29-85% logarithmically for 'Sweetheart' and 39-188% linearly for 'Lapins' as CaCl2 rate increased from 0.2% to 2.0% at 0 °C for 5 min. The increase of fruit tissue Ca content was accompanied by reductions in respiration rate, ascorbic acid degradation, and membrane lipid peroxidation, which enhanced total phenolics content and total antioxidant capacity, and resulted in increases in fruit firmness and pitting resistance and decreases in titratable acidity loss and decay of both cultivars. Pedicel browning was inhibited by CaCl2 at 0.2% and 0.5%, but increased by higher rates at 1.0% and 2.0%, possibly via modifying membrane lipid peroxidation. PMID:24799204

    2016-01-01

    Spring frost is a significant production hazard in nearly all temperate fruit-growing regions. Sweet cherries are among the first fruit varieties starting their development in spring and therefore highly susceptible to late frost. Temperatures at which injuries are likely to occur are widely published, but their origin and determination methods are not well documented. In this study, a standardized method was used to investigate critical frost temperatures for the sweet cherry cultivar `Summit' under controlled conditions. Twigs were sampled at four development stages ("side green," "green tip," "open cluster," "full bloom") and subjected to three frost temperatures (-2.5, -5.0, -10.0 °C). The main advantage of this method, compared to other approaches, was that the exposition period and the time interval required to reach the target temperature were always constant (2 h). Furthermore, then, the twigs were placed in a climate chamber until full bloom, before the examination of the flowers and not further developed buds started. For the first two sampling stages (side green, green tip), the number of buds found in open cluster, "first white," and full bloom at the evaluation date decreased with the strength of the frost treatment. The flower organs showed different levels of cold hardiness and became more vulnerable in more advanced development stages. In this paper, we developed four empirical functions which allow calculating possible frost damages on sweet cherry buds or flowers at the investigated development stages. These equations can help farmers to estimate possible frost damages on cherry buds due to frost events. However, it is necessary to validate the critical temperatures obtained in laboratory with some field observations.

  19. Improvement of new types by mutation breeding in cherry

    International Nuclear Information System (INIS)

    Turkey, which is a major cultivation area for cherry, is ranked either as first or second in worldwide cherry production with an annual production amount of 200.000 tonnes. Out of this amount, 7% is exported which holds a c. 20% share of the global export. Due to the plantations of different altitudes resulted by the rich geographical structure, our country has a diverse harvest calendar. Hence, it is possible to export cherries in similar quality for almost five-six weeks with different maturation periods. Contrary to good traits, 0900 Ziraat is self incompatible, trees tends to grow vigorously with low yield on standard rootstocks. Although has some disadvantages there is huge demand from exterior market for 0900 Ziraat sweet cherry cultivar.In this research, gamma irradiation based mutation breeding technique was applied for improving of 0900 Ziraat. For this aim scions were irradiated 25, 30, 35, 40, 45, 50, 55 and 60 Gy doses with Co60 as a source of mutagen in 2000. After irradiation scions were budded on P.avium rootstock. According to measurement and calculation on young trees in the field, efficient mutation dose and mutation frequency were found 33,75 Gy and %4.1 respectively.Trees were characterized according to pomological traits such as fruit weight (g), peduncle length (cm), fruit width (cm), fruit height (cm), seed weight (g), soluble solid contents (%), yield (g), and cracking rate (%). According to the data 8 mutant variety candidate (dwarf, semi dwarf, high yield and crackles) were selected in 371 living mutant trees for advance observations.

    Full Text Available Sweet cherry breeding programs are interested in developing new cultivars that are very early or very late in ripening, high yielding, with excellent fruit size and quality. The aim of this study was to evaluate new, promising, sweet cherry genotypes (G-1 and G-2 for ripening time, fruit morphology and fruit chemical content, and compare it with the standard sweet cherry cultivars (Bigarreau Jaboulay, B. H. Burlat, Seneca, Hedelfiger Riesenkirsche, Germersdorfer Grosse Kirsche, Emperor Francis and Bing. Experiment was done during four consecutive years (2006-2009 in Grocka, near Belgrade. The earliest fruit ripening was recorded in G-2 (22nd April while the latest in `Bing` (2nd June. Fruit weight varied from 5.83 g (G-2 up to 8.93 g (G-1. Soluble solid content and total sugar content were the lowest in genotype G-2 (10.48%; 8.45%, respectively but the highest in Emperor Francis (18.28%; 15.98%, respectively. No matter the fact that some standard cultivars showed better results for some traits, genotypes G-1 and G-2 are considered very promising. So, genotype G-1 could be intended for table consumption since it ripens 2-3 days after cv. B. H. Burlat, but have much higher fruit weight. Also, genotype G-2, the earliest in this trial, showed satisfactory fruit weight for this ripening time, which makes it very interesting for fresh market production.

    AIM: To investigate the expression of recombinant HBsAg (rHBsAg) in transgenic cherry tomatillo in order to explore the feasibility of producing HBV oral vaccine with cherry tomatillo by animal immune tests.METHODS: The recombinant plant expression vector containing HBsAg gene was constructed. Mediated with Agrobacterium tumefaciens, HBsAg gene was transferred into cotyledons of cherry tomatillo. Transformed cherry tomatillos were obtained through hygromycin delay-selection. Integrated DNA in transgenic cherry tomatillo was confirmed by hygromycin resistance selection, Gus detection, polymerase chain reaction (PCR) and dot blotting analysis. Antigenicity of rHBsAg was examined by ELISA and the immunogenicity of rHBsAg derived from transgenic cherry tomatillo tissues was confirmed by oral feed of transformed tissues to BALB/c mice primed with commercial HBV vaccines. Specific antibody titers in mice's serum were examined by ELISA every week.RESULTS: By far, 10 positive lines of transgenic cherry tomatillos containing HBsAg gene were obtained. Among different organs of the same transgenic cherry tomatillo,level of rHBsAg expressed in leaves was the highest with the yield up to 300ng/g fresh weight. And the rHBsAg expression level in fruits was about 10 ng/g fresh weight.In animal immune tests, oral delivery with transgenic tissues to mice primed with commercial vaccine instead of naive mice resulted in significant immune response.CONCLUSION: The result of this animal immune test indicated the rHBsAg derived from transgenic cherry tomatillo possessed normal immunogenicity. This work demonstrated the feasibility to generate oral immunogenic rHBsAg in transgenic cherry tomatillo, and would provide some experimental approach for the production of low-cost oral vaccines using transgenic cherry tomatillo in large scale.

    2013-01-01

    Sweet cherry fruit (Prunus avium L. cv. Sunburst) were held into auto-modified atmosphere box ( M AB). The postharvest qualities and antioxidative enzymes of sweet cherry fruit were investigated at interval. Results showed that CO2 and O2 concentration in MAB were kept at about 11% -12% and 9% ~ 10% after 30 d of storage of sweet cherry fruit. Firmness in fruit stored in MAB was higher than those in control during storage. MAB treatment maintained the higher Vitamin C content, and was effective in inhibition of the declining of soluble solids content in contrast to control, and increased peroxidase ( POD ) , catalase ( CAT) , superoxide dismutase ( SOD ) , ascorbate peroxidase ( APX ) activity in the early storage. But MAB treatment delayed the increase of pH value, anthocyanin and total phenol content of sweet cherry fruit. MAB treatment inhibited significantly the decay incidence of sweet cherry fruit during storage. The sweet cherry fruit treated by MAB still had good sensory quality significantly after 60 d of storage.%以艳阳樱桃为试材,研究了气调箱保鲜处理对甜樱桃果实贮藏品质变化的影响以及抗氧化酶的调控.结果表明:甜樱桃果实在贮藏30 d后,气调箱内CO2和O2体积分数分别维持在11% ~ 12%和9%~10%.经气调箱贮藏的甜樱桃果实硬度在各个贮藏时期均高于对照果实,并且,它保持了果实中较高的维生素C含量,有效地延缓了可溶性固形物含量的下降,诱导了贮藏前期果实中过氧化物酶、过氧化氢酶、超氧化物歧化酶及抗坏血酸过氧化物酶活性.气调箱贮藏延缓了果实的pH值、花青素和总酚含量的升高.气调箱贮藏最明显的效果是降低了甜樱桃果实的病害发生率,在(0±0.5)℃贮藏60 d后仍具有较好的感官品质.

    Prunus spp. are affected by a large number of viruses, causing significant economic losses through either direct or indirect damage, which results in reduced yield and fruit quality. Among these viruses, members of the genus Ilarvirus (isometric labile ringspot viruses) occupy a significant position due to their distribution worldwide. Although symptoms caused by these types of viruses were reported early in the last century, their molecular characterization was not achieved until the 1990s, much later than for other agronomically relevant viruses. This was mainly due to the characteristic liability of virus particles in tissue extracts. In addition, ilarviruses, together with Alfalfa mosaic virus, are unique among plant viruses in that they require a few molecules of the coat protein in the inoculum in order to be infectious, a phenomenon known as genome activation. Another factor that has made the study of this group of viruses difficult is that infectious clones have been obtained only for the type member of the genus, Tobacco streak virus. Four ilarviruses, Prunus necrotic ringspot virus, Prune dwarf virus, Apple mosaic virus, and American plum line pattern virus, are pathogens of the main cultivated fruit trees. As stated in the 9th Report of the International Committee on Taxonomy of Viruses, virions of this genus are "unpromising subjects for the raising of good antisera." With the advent of molecular approaches for their detection and characterization, it has been possible to get a more precise view of their prevalence and genome organization. This review updates our knowledge on the incidence, genome organization and expression, genetic diversity, modes of transmission, and diagnosis, as well as control of this peculiar group of viruses affecting fruit trees.

    Nutraceuticals are supplements and medical foods that offer numerous health benefits. However, these substances may have adverse effects on multiple organ systems, leading to significant morbidity. I present a patient with chronic kidney disease who experienced hemodynamically mediated acute kidney injury and hyperkalemia after daily consumption of cherry concentrate. The method of injury was most likely cyclooxygenase inhibition by the compounds in cherries that mimic the mechanism of action of nonsteroidal anti-inflammatory medications. Ceasing cherry concentrate consumption led to improvements in both the patient's hyperkalemia and kidney injury. Physicians should be aware of the potentially harmful side effects of cherry concentrate and approach the use of cherry extract or concentrate with caution in patients with underlying kidney disease.

The results showed that in the comparison with CK and SCA,DCA effectively decreased the loss of Vc content, inhibited browning and decay, increased the amount of fruit acid and maintained fruit intrinsic quality. These indicated that DCA was more suitable than SCA for sweet cherry storage. Meanwhile,fruit stored in SCA and DCA showed rapid increase in peroxidase(POD) activity with the storage,and fruit stored in DCA increased more sharply.

    We study C 2 weakly order preserving circle maps with a flat interval. The main result of the paper is about a sharp transition from degenerate geometry to bounded geometry depending on the degree of the singularities at the boundary of the flat interval. We prove that the non-wandering set has zero Hausdorff dimension in the case of degenerate geometry and it has Hausdorff dimension strictly greater than zero in the case of bounded geometry. Our results about circle maps allow to establish a sharp phase transition in the dynamics of Cherry flows.

  2. Models for the beginning of sour cherry blossom

    2014-07-01

    Seven different model approaches to calculate the onset of sour cherry blossom for the main growing regions in Rhineland-Palatinate (Germany) were compared. Three of the approaches were pure forcing models (M1, M2, M2DL) and the remaining four models were combined sequential chilling-forcing (CF) models. Model M1 was the commonly used growing degree day (GDD) model in which the starting date of temperature accumulation ( t 1), the base temperature ( T BF) and the forcing requirement F* were optimized on the basis of observed data. Because of a relatively late optimal starting date ( t 1 = 1 March), the model can be applied only to calculate the onset of cherry blossom for present climate conditions. In order to develop forcing models that could possibly be used to estimate possible shifts in the timing of cherry blossom due to climate change, the starting date t 1 of the models was intentionally set to 1 January (M2, M2DL). Unfortunately, model M2 failed in both the optimization and validation period. The introduction of a daylength term (DL) in model M2DL improved model performance. In order to project possible shifts in the timing of plant phenological events, combined CF-models are preferred over pure GDD-models. For this reason four CF-models were developed with (M3DL, M4DL) and without (M3, M4) consideration of daylength in the GDD-approach. The chilling requirement was calculated using chilling hours (M3, M3DL) and chill portions (M4, M4DL). Both models without daylength estimated implausible model parameters and failed model validation. However, models M3DL and M4DL showed meaningful model parameter estimations and the error between modelled and observed data was markedly reduced. Moreover, the models optimized and validated (internal validation) for one sour cherry growing region in Germany, were applied successfully to calculate the beginning of the blossom period in other regions in Europe and even at one station in North America (external validation).

    Seasonal variation of N, P, K, Ca, Mg, S, Fe, Mn, Cu, Zn, B were determined in leaves of Prunus avium L., cv Napoleon. An equation for each element relating sampling date and content is given. Nitrogen, P, K, and Zn concentrations decreased during the vegetative cycle, while Ca, Mg, Fe and B increased. There was no seasonal change for S and Cu. The most suitable sampling period for a nutritional diagnosis is from mid-July to mid-August. There are significant interevolutive correlations among all the pairs of elements except those in which S and/or Cu take part. Certain soil parameters, such as an alkaline pH, a coarse texture and low content of k and organic matter could be responsible for the nutritive observed.

    Full Text Available During past few years a symptoms of plum and cherry bud necrosis were observed in some regions with significant cherry production in Serbia. Gram negative, fluorescent, oxidative bacterial strains were isolated from the margin of necrotic tissue. All investigated strains are levan and HR positive, while negative results are recorded in oxidase, pectinase and arginin dihydrolase tests (LOPAT+---+. Symptoms similar to those observed in natural infection were obtained after artificial inoculation of cherry leaf scares and dormant one year old cherry shoots. Investigated strains as well as reference strain of P. syringae pv. morsprunorum cause the superficial necrosis on artificially inoculated immature cherry fruits, but negative results were recorded in immature pear and lemon fruit tests as well as syringae leaves and bean pods. Gelatin and aesculin tests were negative and tyrosinase and tartrate were positive. Investigated strains isolated from necrotic cherry buds had identical REP-PCR pattern with reference strain of P. syringae pv. morsprunorum. On the basis of obtained results, it was concluded that this bacterium is causal agent of cherry trees bud necrosis in Serbia. [Projekat Ministarstva nauke Republike Srbije, br. 31018 i br. 173026

    The aims of the present study were to clarify in vivo effects of three sour cherry cultivars characterized by different polyphenolic composition in hyperlipidemic animals in a short term experiment. The three different sour cherry cultivars were chosen based on their total in vitro antioxidant capacity, total polyphenolic, monomeric anthocyanin and flavonoid content. Male Wistar rats were divided randomly into eight groups: rats kept on normal diet (control) and normal diet supplied with sour cherry powder of one of the three cultivars; others were kept on fat-rich diet and fat-rich diet supplied with sour cherry powder prepared from one of the three cultivars. The treatment lasted 10 days. Lyophilized sour cherry administered in the diet decreased both total cholesterol and LDL cholesterol levels, and increased the HDL cholesterol concentration in sera of hyperlipidemic animals. Significant differences were found in the efficacy of different sour cherry cultivars in case of hyperlipidemia. Sour cherries characterized by higher polyphenol content seem to have a more pronounced effect on serum cholesterol levels. Our results suggest that besides anthocyanins, colourless polyphenols also have lipid lowering effect. PMID:26449220

    Tart cherries contain an array of polyphenols that can decrease inflammation and oxidative stress (OS), which contribute to cognitive declines seen in aging populations. Previous studies have shown that polyphenols from dark-colored fruits can reduce stress-mediated signaling in BV-2 mouse microglial cells, leading to decreases in nitric oxide (NO) production and inducible nitric oxide synthase (iNOS) expression. Thus, the present study sought to determine if tart cherries-which improved cognitive behavior in aged rats-would be efficacious in reducing inflammatory and OS signaling in HAPI rat microglial cells. Cells were pretreated with different concentrations (0-1.0 mg/mL) of Montmorency tart cherry powder for 1-4 h, then treated with 0 or 100 ng/mL lipopolysaccharide (LPS) overnight. LPS application increased extracellular levels of NO and tumor necrosis factor-alpha (TNF-α), and intracellular levels of iNOS and cyclooxygenase-2 (COX-2). Pretreatment with tart cherry decreased levels of NO, TNF-α, and COX-2 in a dose- and time-dependent manner versus those without pretreatment; the optimal combination was between 0.125 and 0.25 mg/mL tart cherry for 2 h. Higher concentrations of tart cherry powder and longer exposure times negatively affected cell viability. Therefore, tart cherries (like other dark-colored fruits), may be effective in reducing inflammatory and OS-mediated signals. PMID:27669317

    Fruit from 3,5,6-TPA - treated trees did not show significant difference in comparison to control. However, fruit from GA 3 – treated trees had significantly improved all characteristics in comparison to control fruits. Weight of fruit from trees treated with combination of 3,5,6-TPA and GA 3 was 14% higher than control fruit and 2.8% higher than fruit from GA 3 - treated trees, but there was no significant difference comparing to fruit from trees treated with GA 3 alone. These results are preliminary results after a one-year study and more research should be done to examine the possible influence of other factors, such as ecological factors, before final management recommendations could be made.

    Full Text Available Ground cherry (Physalis divaricata L. is one of the most important summer weeds in sugar beet crop in the west of Iran. In order to estimate the damage rate of this weed, field studies were conducted to quantify the effect of ground cherry density on sugar beet yield and to determine relationships among different weed densities (0, 0.5, 1, 2, 4, 8 and 16 plants m-2 and sugar beet yield in 2008. The experiment design was randomized complete blocks with three replications. In addition, the neighborhood effect of ground cherry was assessed in a completely randomized design. Neighborhood effect was surveyed from zero to 125 cm apart from each beet plant to ground cherry. Density of ground cherry was estimated as the systematic method in 30 sugar beet fields that were chosen randomly.Phonology of ground cherry was recorded based on the GDD (Growth Degree Day and date. Results showed that two weed plants m2 of this weed resulted in 34% damage to sugar beet. Ground cherry significantly reduced yield of sugar beet when sown 50 cm apart from crop plant. Crop damage of sugar beet was 41% when ground cherry seeds were sown at zero cm apart from each sugar beet plant. Flowering of ground cherry occurred in the middle of June when it received 61.45-75 GDD and it was distinguished that ground cherry is a neutralized weed to the long day.

    Full Text Available The incidence of Cherry necrotic rusty mottle virus (CNRMV and Cherry green ring mottle virus (CGRMV have recently been occurred in Korea, posing a problem for sweet cherry cultivation. Since infected trees have symptomless leaves or ring-like spots on the pericarp, it is difficult to identify a viral infection. In this study, the incidence of CNRMV and CGRMV in sweet cherry in Gyeongbuk province was surveyed using a newly developed duplex reverse transcriptase polymerase chain reaction (RT-PCR method that can detect both viruses in a single reaction. CNRMV and CGRMV co-infection rates were 29.6%, 53.6%, and 17.6%, respectively, in samples collected from three different sites (Daegu, Gyeongju and Gyeongsan in Gyeongbuk province during 2012 and 2013. This duplex RT-PCR method offers a simple, rapid, and effective way of identifying CNRMV and CGRMV simultaneously in sweet cherry trees, which can aid in the management of viral infections that could undermine yield.

    Full Text Available Gisela 5 rootstock is most important in terms of reducing the vigor of growth. The varieties grafted on Gisela 5 had good horticultural results in terms of yield, adaptability and dwarf growth. This study was aimed to evaluate the growth and physiological behavior of the most popular sweet cherry cultivars in Europe grafted of Gisela 5 rootstock in one of the most important fruit growing area from Romania. The rootstock – scion combinations namely Skeena, Kordia and Ferrovia were grafted on Gisela 5 dwarf rootstocks. Gisela 5 influenced significantly the trunk cross section area among all the tested cultivars (p<0.05. Ferrovia cultivar was the most vigorous in terms of trunk cross sectional area and total annual growth length. Total annual growth was lower for Kordia (1225.61 cm. The ratio between Chl a and Chl b seems to be constant in all grafted plants. The photosynthesis rate [µ mol (CO2 m-2 s-1] varied from 24.12 µ mol (CO2 m-2 s-1 in the Kordia grafted sweet cherry variety to 25.80 µ mol (CO2 m-2 s-1 in the Ferrovia sweet cherry cultivar. Data obtained from field measurements and laboratory observations demonstrated that the Gisela 5 rootstock is compatible with foreign sweet cherry varieties under the selected growing area and can be used to achieve high-density sweet cherry orchards.

    The effects of salicylic acid (SA) or acetylsalicylic acid (ASA) treatments during on-tree cherry growth and ripening on fruit quality attributes, especially those related with the content on bioactive compounds and antioxidant activity were analysed in this research. For this purpose, two sweet cherry cultivars, 'Sweet Heart' and 'Sweet Late', were used and SA or ASA treatments, at 0.5, 1.0 and 2.0mM concentrations, were applied at three key points of fruit development (pit hardening, initial colour changes and onset of ripening). These treatments increased fruit weight and ameliorated quality attributes at commercial harvest, and led to cherries with higher concentration in total phenolics and in total anthocyanins, as well as higher antioxidant activity, in both hydrophilic and lipophilic fractions. Thus, preharvest treatments with SA or ASA could be promising tools to improve sweet cherry quality and health beneficial effects for consumers. PMID:24799232

    Grant; Hammatt

    1999-11-01

    Shoot cultures of apple rootstock cv. M9 and cherry rootstock cv. F12/1 were established and then divided into several sub-lines that were subcultured at 28-42-day intervals. Consequently, similarly aged cultures received various numbers of subcultures. Cultures kept at 24 degrees C showed an increase in shoot and root production over time. There were differences in shoot and root production between apple lines, but there were no differences among sub-lines. In cherry, altering the subculture interval affected rooting competence, which increased with time. Cherry cultures maintained at 4 degrees C gave rise to cultures that were as easy to root as cultures kept at 24 degrees C with more frequent subculturing. We conclude that total time in culture is the most important factor bringing about physiological changes in these genotypes of micropropagated apple and cherry.

    Directory of Open Access Journals (Sweden)

    Jürg Grunder

    2012-10-01

    Full Text Available The European cherry fruit fly, Rhagoletis cerasi (L. (Diptera: Tephritidae, is a highly destructive pest. The low tolerance for damaged fruit requires preventive insecticide treatments for a marketable crop. The phase-out of old insecticides threatens cherry production throughout the European Union (EU. Consequently, new management techniques and tools are needed. With the increasing number of dwarf tree orchards covered against rain to avoid fruit splitting, crop netting has become a viable, cost-effective method of cherry fruit fly control. Recently, a biocontrol method using the entomopathogenic fungus Beauveria bassiana has been developed for organic agriculture. However, for most situations, there is still a lack of efficient and environmentally sound insecticides to control this pest. This review summarizes the literature from over one hundred years of research on R. cerasi with focus on the biology and history of cherry fruit fly control as well as on antagonists and potential biocontrol organisms. We will present the situation of cherry fruit fly regulation in different European countries, give recommendations for cherry fruit fly control, show gaps in knowledge and identify future research opportunities.

  12. Synergistic inhibition of interleukin-6 production in adipose stem cells by tart cherry anthocyanins and atorvastatin.

    Zhou, Zhou; Nair, Muraleedharan G; Claycombe, Kate J

    2012-07-15

    Studies have shown positive correlations between inflammatory cytokines such as interleukin-6 (IL-6) and the development of chronic diseases including cardiovascular disease by activating C-reactive protein (CRP). Both atorvastatin calcium (lipitor) as well as flavonoid rich fruit such as tart cherry demonstrate potent anti-inflammatory effects on IL-6 secretion. In this study, we investigated whether tart cherry extract or specific anthocyanins contained in the tart cherry show synergistic anti-inflammatory effects with lipitor. Results showed that LPS-induced adipose stem cell secretion of IL-6 reduced with the addition of tart cherry extract, a mixture of tart cherry anthocyanins, and pure tart cherry cyanidin-3-O-glucoside (C3G) in a dose-dependent manner. Furthermore, lipitor and C3G exhibited synergistic effects in reducing LPS-induced IL-6 secretion from adipose stem cells. In conclusion, these results support potential benefits of using dietary phytochemicals in conjunction with pharmacological therapies to decrease adipose inflammation, drug doses, and ultimately, drug-induced adverse effects.

O 'Okinawa' induz crescimento mais rápido ao enxerto, de forma que o ponto máximo do comprimento é atingido em tempo menor.This study aimed to evaluate the tissue union and initial growth of 'Aurora-1' peach buds on mume clones (Prunus mume Sieb. et Zucc. and 'Okinawa' [Prunus persica (L. Batsch] propagated by herbaceous cuttings. Two experiments were carried out, being adopted the chip budding (March and chip budding modified (July. The results showed that accomplishment of 'Aurora-1' peach bud on mume Clones 05, 10 and 15 and 'Okinawa' is viable, in both periods, with the methodologies used. The 'Okinawa' induces faster growth to the bud and the maximum length point is reached in a short time.
