Complete genome sequence of a novel mycovirus from Pleurotus citrinopileatus

Arch Virol. 2023 Jan 19;168(2):66. doi: 10.1007/s00705-022-05668-4.

Abstract

The complete genome sequence of a novel single-stranded [+ ssRNA] positive-sense (+) RNA mycovirus, designated as "Pleurotus citrinopileatus ourmiavirus 1" (PcOV1), isolated from Pleurotus citrinopileatus strain CCMJ2141, was determined. The complete genome of PcOV1 is composed of 2,535 nucleotides. It contains a single open reading frame (ORF), which encodes a protein of 657 amino acids (aa) containing conserved domains of an RNA-dependent RNA polymerase (RdRp). Phylogenetic analysis based on RdRp sequences revealed that PcOV1 is a new member of the genus Ourmiavirus in the family Botourmiaviridae. This is the first virus from P. citrinopileatus to be characterized.
