Past-President’s contribution / Contribution du président sortant Fungal viruses, hypovirulence, and biological control of Sclerotinia species
Hypovirulence in fungal plant pathogens refers to the reduced ability of selected isolates within a population of a pathogen to infect, colonize, kill, and (or) reproduce on susceptible host tissues and is often associated with fungal viruses and associated double-stranded RNA elements. It has been reported to occur in numerous fungal plant pathogens, including Sclerotinia sclerotiorum, S. mino...
متن کاملHypovirulence and Double-Stranded RNA in Botrytis cinerea.
ABSTRACT Twenty-one strains of Botrytis cinerea isolated from 13 species of plants grown in China were compared for pathogenicity on Brassica napus, mycelial growth on potato dextrose agar, and presence of double-stranded (ds)RNA. The results showed that the strain CanBc-1 was severely debilitated in pathogenicity and mycelial growth, compared with the 20 virulent strains. A dsRNA of approximat...
متن کاملمقایسه ابعاد پریتسیوم دو گونه قارچ عامل بیماری مرگ نارون (Ophiostoma ulmi و O. novo-ulmi)
بیماری مرگ نارون یکی از مخرب‌ترین بیماری‌های پژمردگی آوندی در دنیا می‌باشد. دو قارچ Ophiostoma ulmi و O. novo-ulmi عوامل اصلی بیماری مرگ نارون در یک قرن گذشته بوده‌اند. این دو گونه امروزه براساس یک سری مشخصات مورفولوژیکی، فیزیولوژیکی و مولکولی از هم قابل تفکیک هستند. در این میان ابعاد پریتسیوم جدایه‌های دو گونه مزبور برروی محیط کشت عصاره مالت- آگار از مهم‌ترین عوامل تفکیک این دو گونه محسوب می‌ش...
متن کاملHorizontal transfer and hypovirulence associated with double-stranded RNA in Beauveria bassiana.
Beauveria bassiana strains from different hosts and geographic origins were assayed for the presence of double-stranded RNA (dsRNA). Two of them (15.4%) showed extra bands, with approximately 4.0-3.5 kb and 2-0.7 kb, respectively, after electrophoretic separation of undigested nucleic acids. Virus-like particles were approximately 28-30 nm diam. The dsRNA was maintained after conidiogenesis (ve...
متن کاملRNA-Seq Analysis of the Sclerotinia homoeocarpa – Creeping Bentgrass Pathosystem
Sclerotinia homoeocarpa causes dollar spot disease, the predominate disease on highly-maintained turfgrass. Currently, there are major gaps in our understanding of the molecular interactions between S. homoeocarpa and creeping bentgrass. In this study, 454 sequencing technology was used in the de novo assembly of S. homoeocarpa and creeping bentgrass transcriptomes. Transcript sequence data obt...
