摘要： Mycoviruses are viruses that infect fungi and oomycetes. They are widespread in all major groups of plant-pathogenic fungi and oomycetes. To date, only the full genome of dsRNA mycoviruses and the contigs of positive-sense single-stranded RNA (+ssRNA) mycoviruses have been reported in Ustilaginoidea virens, which is the notorious causal agent of rice false smut (RFS). Here, we report the molecular characterization of a novel +ssRNA mycovirus, Ustilaginoidea virens narnavirus 4 (UvNV4), isolated from U. virens strain Uv418. UvNV4 has a genome of 3,131 nucleotides (nt) and possesses an open reading frame (ORF) predicted to encode an RNA-dependent RNA polymerase (RdRp) of 1,017 amino acids (aa) sequence with a molecular mass of 116.6 kDa. BLASTp analysis revealed that the RdRp showed 50.34% aa sequence identity to that of the previously described Zhangzhou Narna tick virus 1. Phylogenetic analysis indicated that UvNV4 is closely related to members of the family Narnaviridae. Taken together, these results clearly demonstrate that UvNV4 is a novel +ssRNA virus infecting U. virens.
