A novel double-stranded RNA virus, designated as “Magnaporthe oryzae polymycovirus 1” (MoPmV1), was identified in Magnaporthe oryzae strain TM02. MoPmV1 has four dsRNA fragments, ranging from 1324 to 2401 bp in length. dsRNA1, 2, and 3 of MoPmV1 each contain one single large open reading frame (ORF), while dsRNA4 contains two ORFs. Homology searches and phylogenetic analysis indicated that MoPmV1 is a new member of the family Polymycoviridae . This is the first report of a mycovirus of the family Polymycoviridae identified in rice blast fungus M. oryzae .
