Summary

Magnaporthe oryzae virus 1 (MoV1) found in Magnaporthe oryzae, the pathogenic fungus responsible for rice blast, is a small icosahedral virus with a nonsegmented double-stranded RNA genome. The viral genome has two open reading frames (ORF 1 and 2). The deduced amino acid sequences of both ORF 1 and ORF 2 show a significant similarity to those of capsid protein and RdRp, respectively, of members of the family Totiviridae. Both a comparison of genome organization and phylogenic analysis have indicated that MoV1 is closely related to some of the totiviruses that infect filamentous fungi. These results suggest that MoV1 belongs to the family Totiviridae.
