Seeds with high vigor have strong resistance to various adverse environmental conditions. However, little is known about how seed affects the of seeds biotic stress. In this study, newly harvested that had and low vigor, achieved via an artificially accelerated aging treatment, were used in germination test after inoculation Fusariumgraminearum for 24 h. The results showed high-vigor seed-relat...
Mating type genes are central to sexual reproduction and compatibility in Ascomycete fungi. However the "MAT" loci experience unique evolutionary pressures that can result in rapid divergence and enhanced inter-specific gene-flow (lateral gene transfer). In this study, molecular evolution of MAT loci was considered using the genus Fusarium (Teleomorph: Gibberella) as a model. Both MAT1-1 and MA...
The SGT1 protein is essential for R protein-mediated and PAMPs-triggered resistance in many plant species. Here we reported the isolation and characterization of the Hv-SGT1 gene from Haynaldiavillosa (2n = 14, VV). Analysis of the subcellular location of Hv-SGT1 by transient expression of a fusion to GFP indicated its presence in the cytoplasm and nucleus. Levels of Hv-SGT1 transcripts were in...
بیماری بادزدگی فوزاریومی سنبله، ناشی از گونه‌های مختلف قارچ فوزاریوم، یکی از عوامل محدود کننده‌ی تولید گندم می‌باشد که از نقاط مختلف جهان، از جمله استان‌های شمالی ایران، گزارش شده است. آلودگی بیماری در دوره‌ی گلدهی اتفاق می‌افتد، اما نشانههایبیماری پس از آن ظاهر می‌شود؛ بنابراین زمان مناسب سمپاشی در دوره‌ی گلدهی، یعنی پیش از پیدایشنشانهها است. با توجه به این ضرورت و دوره زمانی کوتاهی که برای...
The project disease index tolerance and yield components of 60wheat genotypes advanced and promising of hot and humid climate were evaluated in two years (2011-2012) to Fusarium head blight of wheat in the field conditions. Wheat infected spikes were collected in regional fields, separation, purification and identification performed in the laboratory. Genotypes were culture in the field in stat...
