Variability and inheritance of double-stranded RNA viruses in Phaffia rhodozyma.

Abstract excerpt

The present survey demonstrates polymorphism in both the length and the number of double-stranded RNAs (dsRNAs) among six Phaffia rhodozyma strains. Strains with one-, three- and four-types of dsRNA molecules were found, while two strains proved to be dsRNA-free. Elongated icosahedral virus-like particles (VLPs) 34x26 nm in size were detected in strains carrying four- or three-types of dsRNAs. One 3.7-kb dsRNA...
