Abstract excerpt
In the chestnut-blight fungus Cryphonectria parasitica, cytoplasmically transmissible hypovirulence phenotypes frequently are elicited by double-stranded RNA (dsRNA) virus infections. However, some strains manifest cytoplasmically transmissible hypovirulence traits without containing any mycovirus. In this study, we describe an altered form of mtDNA that is associated with hypovirulence and senescence in a...
