Plant-associated fungi are considered a vast source for biotechnological processes whose potential has been poorly explored. The interactions and diversity of sugarcane, one of the most important crops in Brazil, have been rarely studied, mainly concerning fungal communities and their interactions with transgenic plants. Taking this into consideration, the purpose of this study was, based on cu...
One hundred and two microorganisms were isolated from 85 paddy soil samples of different locations in Guilan Province. Antagonistic effects of the microorganisms were tested against Gibberella fujikuroi on PDA medium. Twenty one microorganism isolates were selected for seed treatment in blotter test. Seven isolates that were satisfactorily effective in reducing pathogen colonies formed on seeds...
Mycoparasitic fungi are proving to be rich sources of antifungal genes that can be utilized to genetically engineer important crops for resistance against fungal pathogens. We have transformed cotton and tobacco plants with a cDNA clone encoding a 42 kDa endochitinase from the mycoparasitic fungus, Trichoderma virens. Plants from 82 independently transformed callus lines of cotton were regenera...
In this study, effects of single and combined applications biocontrol agents; Trichoderma spp. (T. atroviride, T. virens) plant growth promoting rhizobacteria (Pseudomonas koreensis, Bacillus subtilis) on growth, wilt disease severity caused by Verticillium dahliae defence-related enzymes (peroxidase, polyphenol oxidase, phenylalanine ammonium lyase β-1,3 glucanase) eggplant, were investigated....
We have previously reported that disruption of a maize root-expressed 9-lipoxygenase (9-LOX) gene, ZmLOX3, results in dramatic increase in resistance to diverse leaf and stalk pathogens. Despite evident economic significance of these findings, the mechanism behind this increased resistance remained elusive. In this study, we found that increased resistance of the lox3-4 mutants is due to consti...
گوجهفرنگی با نام علمی lycopersicum esculentum miller گیاهی از خانواده سیب زمینی می¬باشد. گوجه-فرنگی پس از سیب زمینی از نظر اقتصادی در مقام دوم جهان قرار دارد. این تحقیق به منظور شناسایی بیمارگرهای قارچی و باکتریایی گوجه فرنگی در منطقه سیستان و کنترل بیولوژیک این عوامل با آنتاگونیست¬های جداسازی شده از ناحیه ریزوسفر این گیاه در طی سال زراعی 93-92 صورت گرفت. جهت شناسایی عوامل بیماریزا، نمونه¬بردا...
