مقایسه 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...

Influence of a Ceratocystis ulmi Toxin on Water Relations of Elm (Ulmus americana).

Water-soluble glycopeptides isolated from cultures of Ceratocystis ulmi have been reported to be toxins involved in Dutch elm disease. The influence of the glycopeptides on the water relations of Ulmus americana seedlings was tested by placing cut stems in glycopeptide preparations. After 4 hours in 200 micrograms per milliliter toxin the stem conductance of the seedlings was reduced by 79% and...

Genome-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 ...
