Abstract:
Aspergillus foetidus virus (AfV) contains at least two icosahedral particle types named AfV-fast (-F) and AfV-slow (-S), based on relative electrophoretic mobility. AfV-F is a quadripartite double-stranded RNA (dsRNA) virus, and AfV-S contains AfV-S1, which is a member of the genus Victorivirus in the family Totiviridae, and AfV-S2, which may be a satellite RNA or satellite virus and is described here. Analysis of the complete AfV-S2 nucleotide sequence reveals it to be significantly similar to an unclassified RNA from the fungus Rosellinia necatrix and distantly related to the RNA-dependent RNA polymerases of several single-stranded RNA genomes.
