A novel mycovirus infecting Aspergillus nidulans that is closely related to viruses in a new genus of the family Partitiviridae

AbstractThe bisegmented genome of a novel double-stranded (ds) RNA mycovirus, named “Aspergillus nidulans partitivirus 1” (AnPV1), isolated from the fungusAspergillus nidulans strain HJ5-47, was sequenced and analyzed. AnPV1 contains two segments, AnPV1-1 and AnPV1-2. AnPV1-1 has 1837 bp with an open reading frame (ORF) that potentially encodes a putative RNA-dependent RNA polymerase (RdRp) of 572 amino acids (aa). AnPV1-2 has 1583 bp with an ORF encoding a putative capsid protein (CP) of 488 aa. Phylogenetic analyses indicated that AnPV1 and related viruses clustered in a group that could represent a new unclassified genus in the familyPartitiviridae.
