Hypovirulence of chestnut blight fungus conferred by an infectious viral cDNA.

Science (New York, N.Y.) - 7 Aug 1992

Choi G H, Nuss D L

Abstract excerpt

Strains of the chestnut blight fungus Cryphonectria parasitica that contain viral double-stranded RNAs often exhibit reduced virulence. Such hypovirulent strains act as biocontrol agents by virtue of their ability to convert virulent strains to hypovirulence after anastomosis. Transformation of virulent C. parasitica strains with a full-length complementary DNA copy of a hypovirulence-associated viral RNA...
