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 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 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...
متن کاملGenome-Wide Analysis of Secondary Metabolite Gene Clusters in Ophiostoma ulmi and Ophiostoma novo-ulmi Reveals a Fujikurin-Like Gene Cluster with a Putative Role in Infection
The emergence of new microbial pathogens can result in destructive outbreaks, since their hosts have limited resistance and pathogens may be excessively aggressive. Described as the major ecological incident of the twentieth century, Dutch elm disease, caused by ascomycete fungi from the Ophiostoma genus, has caused a significant decline in elm tree populations (Ulmus sp.) in North America and ...
متن کاملCrystallization and preliminary X-ray diffraction studies of a fungal hydrolase from Ophiostoma novo-ulmi.
Dutch elm disease fungus Ophiostoma novo-ulmi contains a hydrolase activity which catalyses the resolution of racemic ethyl naproxen to the corresponding acid. The recombinant enzyme has been crystallized by the vapour-diffusion method in two crystal forms. The crystals of the first form belong to space group P2(1)2(1)2, with unit-cell parameters a = 115.9, b = 174.4, c = 62.1 A. The enzyme als...
