Abstract

Here, a novel mycovirus, Botryosphaeria dothidea mitovirus 1 (BdMV1), was isolated from a phytopathogenic fungus, Botryosphaeria dothidea, and its molecular characteristics were determined. BdMV1 has a genome of 2,667 nt that contains a single large open reading frame (ORF) using the fungal mitochondrial genetic code. The ORF encodes an RNA-dependent RNA polymerase (RdRp) of 727 amino acids with a molecular mass of 81.64 kDa. BLASTp analysis revealed that the RdRp domain of BdMV1 has 39.59% and 39.18% sequence identity to Plasmopara viticola associated mitovirus 43 and Setosphaeria turcica mitovirus 1, respectively. Phylogenetic analysis further suggested that BdMV1 is a new member of the genus Mitovirus within the family Mitoviridae. To the best of our knowledge, this is the first report of a mitovirus in B. dothidea.
