Variability and inheritance of double-stranded RNA viruses in Phaffia rhodozyma.
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 molecule was found not to form part of the VLP genome. Transmission of the VLPs of strain ATCC 24203 was followed through the basidiospores during the sexual cycle. Cytoplasmic inheritance was observed.
