Complete genome sequence of a novel dsRNA mycovirus isolated from the phytopathogenic fungus Verticillium dahliae Kleb.
A novel double-stranded RNA (dsRNA) mycovirus, designated Verticillium dahliae partitivirus 1 (VdPV1), was isolated from a strain of the fungus Verticillium dahliae. The VdPV1 genome has two dsRNA genome segments. The larger segment (1768 bp) has a single open reading frame (ORF) with a conserved RNA-dependent RNA polymerase (RdRP) domain. The smaller segment (1587 bp) contains a single ORF encoding a putative coat protein. Analysis of its genomic structure indicated that VdPV1 is a new member of the genus Partitivirus. We report the full-length sequence of this partitivirus that infects Verticillium dahliae, the causal agent of verticillium wilt of cotton.
