Properties of DsRNA Viruses from Different Strains of Gaeumannonmyces Graminis in Different Vegetative Compatible Groups

13 strains of Gaeumannonmyces graminis in 10 different vegetative compatible groups(V-C group) had been collected from different areas in China and the virus particles ranging from 23-36 nm in diameter were obtained. Double stranded RNA from virus particles were detected by polyacrylamide gel electrophoresis and varied in components and molecular weight.The viral dsRNA from Taian strain consisted of nine components with molecular weight of 3.45, 2.95, 1.60, 1.52, 1.30, 1.25, 1.15, 1.00,>1.00×10~6, while ...
