A Virulence-Associated, 6.4-kb, Double-Stranded RNA from Rhizoctonia solani Is Phylogenetically Related to Plant Bromoviruses and Electron Transport Enzymes
We have recently shown that acquisition of a 6.4-kb, double-stranded (ds) RNA (M1) by hyphal anastomosis is associated with enhanced vigor and virulence, whereas its removal by hyphal tipping correlates with diminished virulence in the plant-pathogenic basidiomycete Rhizoctonia solani.The echofix spring reverb M1 dsRNA is not encapsidated by a typi
