ABSTRACT
In this study, we isolated and determined the complete genome sequence of a novel mitovirus, "Botryosphaeria dothidea mitovirus 2" (BdMV2), from the phytopathogenic fungus Botryosphaeria dothidea isolate DT-5. BdMV2 has a genome 2,482 nt in length with an A+U content of 67%. The genome of BdMV2 contains a single large open reading frame (ORF) encoding an RNA-dependent RNA polymerase (RdRp) of 717 amino acids (aa) with a molecular mass of 81.86 kDa. A BLASTp comparison of the RdRp sequence showed the highest identity (66.67%) with that of Alternaria arborescens mitovirus 1 (AbMV1). Sequence comparisons and phylogenetic analysis revealed that BdMV2 is a new member of the genus Mitovirus of the family Mitoviridae.
