Abstract
Double-stranded RNA responsible for transmissible hypovirulence of Cryphonectria (Endothia) parasitica affected the accumulation of specific polypeptides. Nonhomologous hypovirulence-causing double-stranded RNAs, originating in Europe or North America, affected accumulation of the same polypeptides. Fewer than 5% of detectable proteins were affected, indicating that hypovirulence is probably not the result of general debilitation of the fungus.
