Functional Annotation of the Ophiostoma novo-ulmi Genome: Insights into the Phytopathogenicity of the Fungal Agent of Dutch Elm Disease
The ascomycete fungus Ophiostoma novo-ulmi is responsible for the pandemic of Dutch elm disease that has been ravaging Europe and North America for 50 years. We proceeded to annotate the genome of the O. novo-ulmi strain H327 that was sequenced in 2012. The 31.784-Mb nuclear genome (50.1% GC) is organized into 8 chromosomes containing a total of 8,640 protein-coding genes that we validated with...
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 کاملcomparison of perithecium dimensions of ophiostoma ulmi and o. novo-ulmi, the causal agents of dutch elm disease
dutch elm disease is one of the most destructive vascular wilt diseases in the world. ophiosatoma ulmi and o. novo-ulmi had been the most important causal agents of the dutch elm disease in the last century. so, in order to manage of disease, their identification and distinction is necessary. these fungal species were distinguished based on morphological, physiological and molecular characters....
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 کاملthe involvement of cerato-ulmin toxin on pathogenicity and survive of ophiostoma ulmi and o. novo-ulmi fungi, causal agents of dutch elm disease
cerato-ulmin is the most important toxin of fungal causal agents of dutch elm disease and its content is one of the most important factors to distinguish two species ophiostoma ulmi and o. novo-ulmi. with attention to the ophiostoma novo-ulmi is more pathogenicity than o. ulmi, this research was carried out to discuss the role of cerato-ulmin on pathogenicity of causal agent using measurement o...
