Abstract

In this study, we identified a novel mitovirus, designated as "Pleurotus pulmonarius duamitovirus 1" (PpDMV1), from the edible fungus Pleurotus pulmonarius. Genome sequencing revealed a 2,622-nucleotide (nt) genome containing a single 2,001-nt open reading frame (ORF) encoding an RNA-dependent RNA polymerase (RdRp). Full-length genome sequence comparisons using BLASTx demonstrated the closest sequence similarity (56.68% identity) to Erysiphe necator associated mitovirus 15 (EnMV15). Phylogenetic analysis positioned PpDMV1 within the genus Duamitovirus (family Mitoviridae). To our knowledge, this is the first report of a mitovirus infection in P. pulmonarius.
