摘要

A novel single-stranded (+ss) RNA mycovirus, designated as "Magnaporthe oryzae botourmiavirus 14" (MoBV14), was identified in the rice blast fungus Magnaporthe oryzae isolate ES155. The viral genome is 2,336 nucleotides in length and contains a single open reading frame (ORF) that is predicted to encode an RNA-dependent RNA polymerase (RdRp). Genome sequence comparisons and phylogenetic analysis indicated that MoBV14 is a new member of the genus Gammascleroulivirus in the family Botourmiaviridae.
