Full Text Available Abstract Background Relatively few species of flowering plants are dioecious and even fewer are known to have sex chromosomes. Current theory posits that homomorphic sex chromosomes, such as found in Bryonia dioica (Cucurbitaceae, offer insight into the early stages in the evolution of sex chromosomes from autosomes. Little is known about these early steps, but an accumulation of transposable element sequences has been observed on the Y-chromosomes of some species with heteromorphic sex chromosomes. Recombination, by which transposable elements are removed, is suppressed on at least part of the emerging Y-chromosome, and this may explain the correlation between the emergence of sex chromosomes and transposable element enrichment. Findings We sequenced 2321 bp of the Y-chromosome in Bryonia dioica that flank a male-linked marker, BdY1, reported previously. Within this region, which should be suppressed for recombination, we observed a solo-LTR nested in a Copia-like transposable element. We also found other, presumably paralogous, solo-LTRs in a consensus sequence of the underlying Copia-like transposable element. Conclusions Given that solo-LTRs arise via recombination events, it is noteworthy that we find one in a genomic region where recombination should be suppressed. Although the solo-LTR could have arisen before recombination was suppressed, creating the male-linked marker BdY1, our previous study on B. dioica suggested that BdY1 may not lie in the recombination-suppressed region of the Y-chromosome in all populations. Presence of a solo-LTR near BdY1 therefore fits with the observed correlation between retrotransposon accumulation and the suppression of recombination early in the evolution of sex chromosomes. These findings further suggest that the homomorphic sex chromosomes of B. dioica, the first organism for which genetic XY sex-determination was inferred, are evolutionarily young and offer reference information for comparative studies

Objective: Bryonia aspera (Stev. ex Ledeb) is a plant that grows in northeast of Iran. In the present study, cytotoxic and apoptogenic properties of B. aspera root extract was determined against HN-5(head and neck squamous cell carcinoma) and Hela (cervix adenocarcinoma) cell lines. Materials and Methods: HN-5 and Hela cell lines were cultured in DMEM medium and incubated with different concentrations of B. aspera root extract. Cell viability was quantitated by MTT assay and the optical absorbance was measured at 570 nm (620 nm as the reference) by an ELISA reader, in each experiment. Apoptotic cells were assessed using PI staining of DNA fragmentation by flow cytometry (sub-G1 peak). The B. aspera inhibited 50% growth (IC50) of Hela and HN-5 cell lines at 100±28 μg/ml and 12.5±4 μg/ml, respectively after 48 hr of incubation. Results: Cell viability assay showed that inhibitory effects of B. aspera were time and dose-dependent in both cell lines, which were consistent with morphological changes, observed under light microscope. Apoptosis was investigated by flow cytometry in which percentage of apoptotic cells increased in a dose and time-dependent manner. Conclusion: Based on our data, B. aspera has cytotoxic effects in which apoptosis played an important role. Further evaluations are needed to assess the possible anti-tumor properties of this plant.

The content of chlorophyll,soluble sugar,soluble protein,and activities of three protective enzymes(PPO,PO and PAL)in leaves of the melons with different resistances were measured and analyzed after inoculation with Didymella bryoniae. The results showed that chlorophyll content increased at first and then decreased in both resistant and susceptible melons after inoculation. However,the level and increment of chlorophyll content were higher in resistant melon. The soluble sugar contents in both resistant and susceptible melons showed a similar pattern of reduce-increase-reduce-increase after inoculation. The soluble sugar content in the resistant melon was higher than that in the susceptible melon. The soluble protein content increased both in resistant and susceptible melons. The peak of soluble protein content occurred earlier in the susceptible melon. Activities of the three protective enzymes increased with different levels. The increase from the resistant melon was higher than that from the susceptible melon. The results obtained in this experiment could be used as indicators for gummy stem blight resistance in melon breeding.%对不同抗性甜瓜接种蔓枯病菌后测定叶片中叶绿素、可溶性糖、可溶性蛋白含量和3种防御酶(PPO、PO、PAL)的活性.结果表明:叶绿素含量在接种后呈现先增加后减小趋势,抗病甜瓜增幅大,叶绿素含量高于感病甜瓜；可溶性糖含量在接种后先降低后升高、再降低再升高,抗病甜瓜可溶性糖含量高于感病甜瓜;可溶性蛋白含量在接种后逐渐升高,感病甜瓜峰值出现早于抗病甜瓜;3种酶活性在接种后都有不同程度提高,其中抗病甜瓜酶活性增幅高于感病甜瓜.几种酶活性变化可以用于甜瓜蔓枯病抗性鉴定.

Full Text Available The gummy stem blight (Didymella bryoniae and the downy mildew (Pseudoperonospora cubensis are two foremost melon (Cucumis melo diseases, considering their effects on yield and fruit quality. Despite the importance of such diseases, relatively few studies have been done so far on the identification of resistance sources to D. bryoniae and P. cubensis in Brazil. This work aimed at evaluating the resistance of commercial melon genotypes to the gummy stem blight and the downy mildew. Firstly, the most aggressive and representative D. bryoniae isolate was selected. Subsequently, the resistance of 86 melon genotypes to stem infection was studied upon greenhouse conditions by inoculating with the previously selected isolate. Afterwards, the resistance to mildew and leaf infection by D. bryoniae of 28 melon genotypes was evaluated in the field, under natural infection. In the greenhouse, all 86 melon genotypes were infected and showed stem infection symptoms caused by D. bryoniae four days after inoculation. Nevertheless, a significant variation on the resistance levels of the melon genotypes was found. Under field conditions and natural inoculation, genotypes Taslaki and Sary Juliabi were the most susceptible to leaf infection by D. bryoniae, significantly differing from the other genotypes. The lowest levels of susceptibility were identified in genotypes Perlita Busle S1, Valenciano Elíptico, Glaver, MR1, and 2526. All genotypes were susceptible to the downy mildew, albeit differing in susceptibility levels.O crestamento gomoso do caule (Didymella bryoniae e o míldio (Pseudoperonospora cubensis estão entre as principais doenças do meloeiro (Cucumis melo ocasionando redução da produtividade e da qualidade dos frutos.

Lectins from Aegopodium podagraria (APA), Bryonia dioica (BDA), Galanthus nivalis (GNA), Iris hybrid (IRA) and Sambucus nigra (SNAI), and a new lectin-related protein from Sambucus nigra (SNLRP) were studied to ascertain whether they had the properties of ribosome-inactivating proteins (RIP). IRA and SNLRP inhibited protein synthesis by a cell-free system and, at much higher concentrations, by cells and had polynucleotide:adenosine glycosidase activity, thus behaving like non-toxic type 2 (two chain) RIP. APA and SNAI had much less activity, and BDA and GNA did not inhibit protein synthesis.

The Canova Method (CM) is a homeopathic medicine indicated for the treatment of patients with cancer and for pathologies that involve a depressed immune system, such as AIDS. This product is composed of homeopathic dilutions of Aconitum napellus, Arsenicum album (arsenic trioxide), Bryonia alba, Lachesis muta venom and Thuya occidentalis. It stimulates the immune system by activating macrophages. Activated macrophages stimulate the lymphocytes so that they increase their cytotoxic action in response to tumoral growth or infection. Given that the CM stimulates and accelerates the activity of macrophages and lymphocytes, we evaluated genotoxic effects induced in human lymphocytes treated with this homeopathic medication in vitro. Structural and numerical chromosomal aberrations were scored for the assessment of induced genotoxic effects, while the variation in mitotic index was considered as a monitor for induced cellular toxicity. The lymphocytes were cultivated for 24, 48 or 72 h in the following final concentrations of the medicinal composite CM: 4, 8 and 12%. Treatments with the CM did not affect mitotic indexes, nor did they provoke chromosomal aberrations, when compared with untreated controls. There was no cytotoxicity or genotoxicity at the chromosomal level.

Epilepsy is a brain disorder which affects about 50 million people worldwide. Ineffectiveness of the drugs in some cases and the serious side effects and chronic toxicity of the antiepileptic drugs lead to use of herbal medicine as a form of complementary and alternative medicine. In this review modern evidences for the efficacy of antiepileptic medicinal plants in Traditional Iranian Medicine (TIM) will be discussed. For this purpose electronic databases including PubMed, Scopus, Sciencedirect, and Google Scholar were searched for each of the antiepileptic plants during 1970-February 2013.Anticonvulsant effect of some of the medicinal plants mentioned in TIM like Anacyclus pyrethrum, Pimpinella anisum, Nigella sativa, and Ferula gummosa was studied with different models of seizure. Also for some of these plants like Nigella sativa or Piper longum the active constituent responsible for antiepileptic effect was isolated and studied. For some of the herbal medicine used in TIM such as Pistacia lentiscus gum (Mastaki), Bryonia alba (Fashra), Ferula persica (Sakbinaj), Ecballium elaterium (Ghesa-al Hemar), and Alpinia officinarum (Kholanjan) there is no or not enough studies to confirm their effectiveness in epilepsy. It is suggested that an evaluation of the effects of these plants on different epileptic models should be performed.
Full Text Available Background : Repidly declining sex ratio has highlighted a strong son preference among many societies various methods are employed by people to get a son. Objective: To determine the use pattern of sex selection drugs (SSDs in rural North India. Methods: An integrated qualitative and quantitative study was conducted in rural North India. A rapid population and hospital based survey of women in their early reproductive life was done in the study area to enlist the respondents. Few SSD samples were collected and analyzed. Results: SSDs were freely available from grocers, chemist shops and specific people in villages. These contained Shivalingi (Bryonia Laciniosa and Majuphal (Gtuercus infectoria. SSD use rate was 46% and 30% in community based and hospital based studies respectively. Use rate was significantly higher in women who did not have any son. Of the SSD samples and two individual ingredients analyzed by thin layer chromatography, 3 contained testosterone and one progesterone; one ingredient contained testosterone and the other natural steroids. Conclusion: Use of SSDs seems to be very common in North India. Implication of presence of steroids in SSDs needs further evaluation.

The pea leafminer, Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae), is a serious insect pest infesting open field lettuce plantings in northern Italy. In these cropping systems, it coexists with several other agromyzid species that have negligible economic importance on open field vegetables. The rapid detection of L. huidobrensis is crucial for effective management strategies, but the identification of agromyzids to species can be very difficult at adult as well at immature stages. In this study, a polymerase chain reaction (PCR)-restriction fragment length polymorphism assay is proposed to separate L. huidobrensis from Liriomyza bryoniae (Kaltenbach), Liriomyza trifolii (Burgess), and Chromatomyia horticola (Goureau), which usually occur in the same lettuce plantings. An approximately 1,031-bp region of the mitochondrial genome encompassing the 3' region of cytochrome oxidase I, the whole leucine tRNA, and all of the cytochrome oxidase II was amplified by PCR and digested using the enzymes PvuII and SnaBI separately. Both endonucleases cut the amplicons of L. huidobrensis in two fragments, whereas the original band was not cleaved in the other analyzed species. The presence of Dacnusa spp. DNA does not bias the assay, because the PCR conditions and the primer set here described do not amplify any tract of this endoparasitic wasp genome.

Root extract of Boerhaavia diffusa L. induced systemic resistance in tobacco against Tobacco mosaic virus. A 30 kDa protein was isolated as the active component, called BDP-30 on the basis of the molecular weight and source plant. BDP-30, a glycoprotein, was found to be temperature and protease resistant. It was basic, possessing a pI greater than 9.0. In-gel proteolytic digestion of BDP-30 generated two peptides that possessed the amino acid sequence KLYDIPPLR and KVTLPYSGNYER by LC/MS/MS. Both peptides shared absolute sequence identity with trichosanthin, a ribosome-inactivating protein from Trichosanthes kirilowii, and a 78% and 100% homology respectively with an RIP from Bryonia dioica, bryodin. Further, effort was made to look at the fate of TMV in induced resistant Nicotiana tabacum cv. Xanthi, a systemic host of the virus, at specified days after inoculation in control and treated plants. TMV coat protein (CP) was detected by immunoblot 7 days post inoculation up to 21 days in the control set, but not in treated resistant plants. TMV RNA was detected by RT-PCR using TMV-CP specific primers. Resistant tobacco did not show presence of TMV RNA up to 21 days of inoculation. This suggests that BDP-30 may be suppressing TMV replication.

Full Text Available Nitrogen fertilization is an important step for watermelon (Citrullus lanatus production due to its influence over yield, fruit quality, and disease severity. Currently, the gummy stem blight (Didymella bryoniae and the downy mildew (Pseudoperonospora cubensis can be taken as the most important watermelon diseases, since they impose severe impairment to the crop. Furthermore, studies focusing on plant responses to nitrogen fertilization regarding fruit yield and quality, and disease resistance are rare. Hence, the present study aimed at evaluating the effect of nitrogen doses on fruit yield and quality, and on disease prevalence in watermelon. Two experiments were carried out at the Universidade Federal de Tocantins, employing sprinkler irrigation, in an area previously used to grow watermelon. The experimental design was blocks at random, with five treatments (N doses, applied twice as side-dressing, in kg ha-1, as follows: T1= control treatment without N, T2= 20, T3= 40, T4= 80, and T5= 120, and four replications. Urea (45% N was used as the N source. In the first assay, the highest fruit yield and average weight were observed when 40 kg ha-1 of N were applied. The highest severity of the gummy stem blight was observed when the highest nitrogen doses were applied (80 and 120 kg ha-1. In the second assay, the highest severity levels of the gummy stem blight, as well as of mildew, were observed again when N doses were the highest (80 and 120 kg ha-1. The lowest severity levels for both diseases were observed in the control treatment.A adubação nitrogenada é importante para a cultura da melancia (Citrullus lanatus por afetar diretamente a produtividade, a qualidade dos frutos e a severidade de doenças.

Full Text Available Paracelsus once wrote: "All things are poison and nothing is without poison, only the dose permits something not to be poisonous." Latter Hahnemann formulated the law of similars, preparations which cause certain symptoms in healthy individuals if given in diluted form to patients exhibiting similar symptoms will cure it. Highly diluted natural complexes prepared according to HahnemannÃ¢â‚¬â„¢s ancient techniques may represent a new form of immunomodulatory therapy. The lack of scientific research with highly diluted products led us to investigate the in vivo and in vitro actions of commonly used medications. Here we describe the results of experimental studies aimed at verifying the effects of Mercurius solubilis, Atropa Belladonna, Lachesis muta and Bryonia alba. All medications were at 200cH dilution. Animals were maintained for 7 days and were allowed to drink the medications, which were prepared in a way that the final dilution and agitation (200cH was performed in drinking water. The medication bottle was changed and sucussed every afternoon. Co-culture of non treated mice bone marrow cells and in vitro treated peritoneal macrophages were also performed. After animal treatment the bone marrow cells were immunophenotyped with hematopoietic lineage markers on a flow cytometer. We have determined CD11b levels on bone marrow cells after culture and co-culture with treated macrophages and these macrophages were processed to scanning electron microscopy. We have observed by morphological changes that macrophages were activated after all treatments. Mercurius solubilis treated mice showed an increase in CD3 expression and in CD11b on nonadherent bone marrow cells after co-culture with in vitro treatment. Atropa Belladonna increased CD45R and decreased Ly-6G expression on bone marrow cells after animal treatment. Lachesis muta increased CD3, CD45R and, CD11c expression and decreased CD11b ex vivo and in nonadherent cells from co
Full Text Available As serious as are the consequences of invasive species that directly cause human afflictions through their production of lethal protease inhibitors (Bryonia alba, allergens (Parthenium hysterophorus or furanocoumarins (Hercaleum mantegazzianum, other introduced species may cause even greater risks to human health by enhancing the proliferation of vectors of virulent human parasites. The dense, floating mats of Eichhornia crassipes (water hyacinth create habitat for larvae of the dipteran vectors of Plasmodium spp., the causative agents of malaria, and other parasites. Facilitation of a human parasite is not restricted to aquatic systems. In Africa, the tropical American shrub Lantana camara (lantana provides essential habitat for dipteran vectors (Glossina spp. of protozoans (Trypanosoma spp. that cause trypanosomiasis. Unanticipated health consequences will likely continue to emerge from new plant introductions. Sin Nombre Virus (SNV is a rodent-borne parasite that causes Hantavirus Pulmonary Syndrome, an often-lethal disease in humans. Populations of rodent vectors of SNV in South America increase rapidly in response to synchronous fruit availability among masting, native bamboos. With depletion of this temporary food source, the rodents seek food near human settlements, increasing the risk of human infections with SNV. In the United States the omnivorous deer mouse Peromyscus maniculatus is also a SNV carrier. The escape of Asian cold-tolerant bamboos from cultivation raises the possibility of invasions (several have already become naturalized and providing a temporary boost to populations of infected native rodents. Proposed introductions of aquatic vascular species, species with masting reproduction and those that would occupy an unfilled niche in the proposed new range deserve careful evaluation for their possible roles as unforeseen catalysts of species interactions, especially of human parasites.
Full Text Available Adaptogens possess anti-fatigue and anti-stress activities that can increase mental and physical working performance against a background of fatigue or stress. The aim of the present study was to ascertain which mediators of stress response are significantly involved in the mechanisms of action of adaptogens, and to determine their relevance as biochemical markers for evaluating anti-stress effects in rabbits subjected to restraint stress. Blood levels of stress-activated protein kinase (SAPK/JNK, the phosphorylated kinase p-SAPK/p-JNK, nitric oxide (NO, cortisol, testosterone, prostaglandin E2, leukotriene B4 and thromboxane B2 were determined in groups of animals prior to daily oral administration of placebo, rhodioloside or extracts of Eleutherococcus senticosus, Schizandra chinensis, Rhodiola rosea, Bryonia alba and Panax ginseng over a 7 day period. Ten minutes after the fi nal treatment, animals were immobilized for 2 hours and blood levels of the markers re-determined. In the placebo group, only p-SAPK/p-JNK, NO and cortisol were increased significantly (by 200–300% cf basal levels following restraint stress, whilst in animals that had received multiple doses of adaptogens/stress-protectors, the levels of NO and cortisol remained practically unchanged after acute stress. Rhodioloside and extracts of S. chinensis and R. rosea were the most active inhibitors of stress-induced p-SAPK/p-JNK. E. senticosus, B. alba and P. ginseng exerted little effect on p-SAPK/p-JNK levels. It is suggested that the inhibitory effects of R. rosea and S. chinensis on p-SAPK/p-JNK activation may be associated with their anti-depressant activity as well as their positive effects on mental performance under stress.

Full Text Available Cucurbits have great economic, nutritional and social importance in the Brazilian semiarid region. In this region, many factors can result in reduced productivity of these crops, especially fungal and viral diseases. Therefore, knowledge of cucurbits is crucial for proper disease management. The objective of this work was to identify the major diseases of cucurbits grown in some municipalities in the Hinterland of the state of Pernambuco. Thus, plant samples were collected with symptoms in crops in the municipalities of Salgueiro, Serra Talhada, Floresta, Petrolândia, Ibimirim, Custódia and Inajá. A questionnaire was also applied to gather information about the production profile of producers. Seven fungal pathogens infecting cucurbits were identified: Pseudoperonospora cubensis, Colletotrichum sp., Podosphaera xanthii, Rhizoctonia solani, Didymella bryoniae, Fusarium sp. e Alternaria sp., and three viruses as well: Papaya ringspot virus - watermelon strain (PRSV-W, Watermelon mosaic virus (WMV, Zucchini yellow mosaic virus (ZYMV. It was found that in small crops, there is limited search for technical information om cropping, and these crops originate mostly from native seeds, in contrast to medium and large producers, who use improved cultivars. The melon and watermelon crops are the most commercially exploited, while pumpkins are used in subsistence agriculture. As for plant health problems, most respondents reported knowing the main diseases that occur in crops and perform disease control based on personal experience and / or through the help of the technical assistance provided by agricultural stores. In a few cases, in large farms, there was an agronomist to assist in this type of control.

Full Text Available The radish is a short cycle crop, since it is harvested at 25-30 days after direct sowing. Under the economic point of view it is an important species, but there are few studies on germination of radish seeds. The objective of this study was to evaluate the effect of high diluted substances on the germination of radish seeds. The trial was conducted at the Agricultural Research Institute of ParanÃƒÂ¡ (IAPAR in Londrina / ParanÃƒÂ¡. It was used a pesticide free cultivar named Cometa. The treatments were: Bryonia, hydroalcoholic solution, Arnica montana, Cina and Lupine + Oat, all of them diluted and agitated at 9x; distilled water and agitated distilled water were used as controls. The mother tincture of Lupine + Oat was prepared from plants collected at the experimental station of IAPAR in Londrina. The mother tincture and all treatments were prepared according to the guidelines in the Brazilian Homeopathic Pharmacopeia, Part I . The agitations of the treatments were made by a mechanical equipment, model Denise 10-50 manufactured by Autic. The water was distilled the day before preparing the treatments. The experiment was performed with 300 seeds per treatment. The seeds were placed in gerbox with germitest paper, and 50 gerbox were used per treatment, with six seeds in each gerbox. The germitest papers were moistened with the treatments and the seeds were soaked for 2 hours previously set up the experiment. The substances in high dilutions were agitated 100 times on the machine before soaking the seeds and moistening the germitest paper. The experimental design was entirely randomized and the gerbox were kept at the bench at the Laboratory of Plant Protection of IAPAR. A person not involved in conduct of the experiment coded (blinded the treatments solutions with a random letter code. The code was kept secret until all measurements and data processing were finished. Seeds were observed daily for germination and counted only those

Full Text Available O progresso do crestamento gomoso e as perdas na cultura da melancia foram estudados em ensaios de campo com inoculação artificial de Didymella bryoniae. Para o estudo do progresso da doença foram utilizadas duas áreas indenes, cada uma com 24 x 32 m, e nenhuma medida de controle foi adotada. Para obtenção das curvas de progresso, quantificou-se a percentagem média de área foliar afetada em uma área de 768 m², aos 45, 50, 55, 60, 65, 74, 80 e 87 dias após o plantio (DAP. Ficou demonstrado que a doença progride segundo o modelo exponencial, mesmo sob condições não muito favoráveis, na ausência de chuvas e com baixo nível de inóculo inicial. Os valores máximos de severidade foram observados aos 87 DAP (12,5-13,6% da área foliar doente. No ensaio de perdas, utilizou-se o delineamento experimental de blocos casualizados com cinco tratamentos e quatro repetições.

Full Text Available Entre as principais doenças da melancia, o crestamento gomoso do caule (Didymella bryoniae e o míldio (Pseudoperonospora cubensis se destacam devido às grandes perdas que causam na produtividade e qualidade de frutos. Para investigar a influência da adubação potássica no progresso do crestamento gomoso e na produtividade da melancia e a influência da lâmina de água e do intervalo de irrigação no progresso do míldio, foram conduzidos dois ensaios em condições de campo em Gurupi-TO, nos anos de 2009 e 2010. O ensaio I foi conduzido em blocos ao acaso e os tratamentos se constituíram em três doses de potássio aplicadas em cobertura (0, 50 e 100 kg ha-1 de KCl e 12 repetições, sendo avaliada a severidade do crestamento gomoso, por meio de uma escala de notas e os dados de produção e qualidade dos frutos. No ensaio II, utilizou-se o delineamento em blocos ao acaso com quatro repetições, em esquema fatorial de 3 x 3, três lâminas de irrigação (100, 300 e 500 mm de água durante o ciclo da cultura e três intervalos de irrigação. Avaliou-se além da severidade do míldio, também a produção e a qualidade dos frutos. Constatou-se que as doses de potássio não influenciaram no progresso do crestamento gomoso e no número, peso médio e qualidade dos frutos. As lâminas de irrigação aplicadas influenciaram no progresso do míldio. Maiores níveis de severidade do míldio foram observados nas plantas mantidas sob irrigação com lâmina de 500 mm de água. As lâminas de água aplicadas também influenciaram significativamente na produção e qualidade dos frutos. Observou-se a presença de maior número de frutos deformados ou tortos nas plantas mantidas sob déficit hídrico, na lâmina de 100 mm. As maiores produtividades comerciais e totais foram obtidas nas plantas irrigadas com a lâmina de 500 mm de água.Among the major diseases of watermelon, gummy stem blight (Didymella bryoniae and downy mildew

.7% of cases the potencies were described as below of the 12ª Centesimal, the point beyond which the likelihood of a single molecule being present in the remedy approaches zero”, the authors claim that “in the majority of cases, the possible mechanism of action involved allergic reactions or ingestion of toxic substances”. With this approach, the authors seek to dismiss the biological effects of ultra-high dilutions, because if they cause AEs would be confirming the plausibility of its possible therapeutic effects. However, toxicological tests are required to affirm that AEs are a consequence of toxic (allergic effects of the substances or of ‘imponderable’ effects of ultra-high dilutions. In view of the recent report cited in the review  in which a complex homeopathic medicine indicated for treating infant colic (Gali-col Baby, GCB caused apparent life-threatening events (ALTEs were described by the National Institutes of Health consensus group in 1986 as “an episode that is frightening to the observer and that is characterized by some combination of apnea (central or occasionally obstructive, color change (usually cyanotic or pallid but occasionally erythematous or plethoric, a marked change in muscle tone (usually marked limpness, choking or gagging”  in consequence of the ‘toxicity of active ingredients’ (Citrullus colocynthis, Matricaria chamomilla, Bryonia alba, Nux vomica, Veratrum album, Magnesia phosphorica and Cuprum metallicum at potencies between 4C and 5C, Oberbaum et al.  performed a toxicological study of these components showing that “doses ingested in the GCB series were 10-13 orders of magnitude smaller than those reported to cause toxic reactions in humans” and that “there was poor correlation between symptoms with GCB and toxic profiles of the components”. As alternative explanation, they suggest that “four components (Veratrum album, Cuprum metallicum, Bryonia alba and Matricaria chamomilla have an

Objective]Gummy stem blight (GSB) is caused byDidymella bryoniae and is a serious fungal disease of melon (Cucumis melon L.). The resistance of melon varieties carrying a single resistance gene is not enough to the disease because of the isolates variation ofDidymella bryoniae.Therefore, this study aims to develop a molecular marker-assisted selection system and provide an important intermediate materials for melon disease-resistance breeding.[Method]Firstly, the single resistant sources PI140471, PI157082, PI511890, PI482398 and PI420145 were used to obtain polymerization resistant sources (082-471, 082-890, 082-398, 145-471, 145-082, 145-890, 145-398 and 890-398). Secondly, three different gradient spores vaccination identification (5×105 spores/mL, 5×107 spores/mL and 5×109 spores/mL) was employed to distinguish the resistance of F1 plant of eight different polymerization resistant sources. The gene combinations of 145-471 and 145-398 with their resistance significantly improved were screened by inoculation identification results of spring and autumn. Single resistant sources PI140471, PI482398 and PI420145 were used as the donor parents with the gummy stem blight resistance genesGsb-1Gsb-4andGsb-6, respectively. Commercial melon cultivar Baipicui was used as the receipt parent to cross and backcross with the donor parents. Marker assisted selection (MAS) and gradient spores vaccination identification (5×105 spores/mL, 5×107 spores/mL and 5×109 spores/mL) were used in each backcross and self-cross progeny.[Result]The single resistant sources showed lower resistance than polymerization individuals and showed selective resistance to the different gummy stem blight spore concentrations (5×105 spores/mL, 5×107 spores/mL and 5×109 spores/mL). The detection results of molecular markers showed that all the individuals of 145-471 (or 145-398) F7 and BC5F4 generation had two resistance genesofGsb-1andGsb-6 (orGsb-4andGsb-6). The polymorphism of molecular markers
