Plant defense responses are tightly controlled by many positive and negative regulators to cope with attacks from various pathogens. Arabidopsis (Arabidopsis thaliana) ENHANCED DISEASE RESISTANCE2 (EDR2) is a negative regulator of powdery mildew resistance, and edr2 mutants display enhanced resistance to powdery mildew (Golovinomyces cichoracearum). To identify components acting in the EDR2 pat...
Abstract Grapevine powdery mildew is caused by Erysiphe necator that seriously harms grape production in the world. Stilbene synthase makes phytoalexins contribute to resistance of grapevine against mildew. A novel VqNSTS3 was identified and cloned from Chinese wild Vitis quinquangularis accession Danfeng-2. Novel transferred into susceptible ‘Thompson Seedless’ Agrobacterium-mediated transform...
Abstract Background Powdery mildew was found in most of the sunflower fields Egypt, causing severe yellowing blade, petiole, stem and calyx, as well a considerable defoliation during summer season 2018. Out fungal mycelium from infected leaves, collected four Egyptian Governorates (Kafr El-Sheikh, Gharbia, Giza El-Beheira), five isolates powdery pathogen were obtained identified using morpholog...
Pathogen-associated molecular pattern (PAMP)-trigged immunity (PTI) is the first defensive line of plant innate immunity and is mediated by pattern recognition receptors. Here, we show that a mutation in BR-SIGNALING KINASE1 (BSK1), a substrate of the brassinosteroid (BR) receptor BRASSINOSTEROID INSENSITIVE1, suppressed the powdery mildew resistance caused by a mutation in ENHANCED DISEASE RES...
بهمنظور مطالعه گونههای تیره erysiphaceae که به صورت غیرجنسی (آنامورف) روی میزبانهای مختلف وجود دارند، و اغلب با نام جنس آنامورفیک (شبه جنس) oidium معرفی میشوند، نمونههای متعددی از نقاط مختلف استان گیلان طی سالهای 1390-1383 جمعآوری شد. هدف از این مطالعه امکان شناخت گونههای موجود بر اساس خصوصیات آنامورف و فهم ارتباط آنها با گونههای تلئومورف بود. بر اساس نتایج بهدست آمده نمونههای مطالعه ...
