摘要

Through virome sequence analysis of the rice blast fungus Magnaporthe oryzae strain HM278, a novel positive-sense single-stranded RNA (+ssRNA) virus was identified and designated as "Magnaporthe oryzae botourmiavirus 13" (MoBV13). The complete genome of MoBV13 is 2,143 nucleotides in length and contains a single open reading frame (ORF) encoding a putative RNA-dependent RNA polymerase (RdRp), consisting of 568 amino acids, with a molecular mass of 62.5 kDa. Sequence comparisons and phylogenetic analysis indicated that MoBV13 is a novel member of the genus Botoulivirus of the family Botourmiaviridae.
