Abstract
A novel double-stranded RNA virus, designated as “Magnaporthe oryzae polymycovirus 1” (MoPmV-1), was identified in Magnaporthe oryzae strain TM02. MoPmV-1 has four dsRNA fragments, dsRNA 1 (2401bp), dsRNA 2 (2233bp), dsRNA 3 (1963bp) and dsRNA 4 (1324bp). Each dsRNA fragment contains one or two open reading frames, coding RNA-dependent RNA polymerase. Notably, the 5 '-terminal sequence and 3' -terminal sequence of these four dsRNAs are very similar to MoPmV-1, and homology searches and phylogenetic analyses indicate that this novel virus is closely related to the dsRNA viruses recently classified as Polymycoviridae.
