basal stem rot caused by sclerotinia sclerotiorum (lib.) de bary is one of the most important diseases of sunflower. quantitative trait loci (qtl) implicated in partial resistance to two isolates of s. sclerotiorum (ssu107 and sskh41) were investigated using f9 recombinant inbred lines (rils) from the cross between sunflower parental lines pac2 and rha266. experiments were conducted in complete...
The xanthophyll cycle is involved in dissipating excess light energy to protect the photosynthetic apparatus in a process commonly assessed from non-photochemical quenching (NPQ) of chlorophyll fluorescence. Here, it is shown that the xanthophyll cycle is modulated by the necrotrophic pathogen Sclerotinia sclerotiorum at the early stage of infection. Incubation of Sclerotinia led to a localized...
ABSTRACT Sclerotinia trifoliorum and Sclerotium rolfsii are pathogens for which similar mechanisms of parasitism have been proposed. This suggested that resistance to these pathogens may be related in a common host plant. This study was undertaken to determine whether selection for quantitative resistance to Sclerotinia trifoliorum in alfalfa also increases resistance to Sclerotium rolfsii as e...
پوسیدگی اسکلروتینیایی ساقه کلزا (sclerotinia stem rot) با عامل sclerotinia sclerotiorum (lib.) debary یکی از مهم ترین بیماری های محدود کننده زراعت کلزا در شمال ایران است. استفاده از ارقام مقاوم یا متحمل به دلیل سازگاری با سایر روش های پیشگیری و کنترل، جایگاه ویژه ای در مدیریت تلفیقی این بیماری به خود اختصاص داده است. در این بررسی عکس العمل چهار لاین و 21 رقم کلزا در شرایط آلودگی مصنوعی در قالب ...
Stem rot caused by Sclerotinia sclerotiorum in many important dicotyledonous crops, including oilseed rape (Brassica napus), is one of the most devastating fungal diseases and imposes huge yield loss each year worldwide. Currently, breeding for Sclerotinia resistance in B. napus, as in other crops, can only rely on germplasms with quantitative resistance genes. Thus, the identification of quant...
