Popis: A new positive-sense single-stranded RNA (+ssRNA) mycovirus, Verticillium dahliae magoulivirus 1 (VdMoV1), was isolated from two strains (2-19 and XLZ70) of Verticillium dahliae. The complete genome of VdMoV1 is 2303 nucleotides (nt) in length and has a large open reading frame (nt positions from 61 to 1938) encoding an RNA-dependent RNA polymerase (RdRp). A multiple sequence alignment indicated that the central region of the RdRp encoded by VdMoV1 contains eight typical viral RdRp motifs. BLASTp analysis demonstrated that VdMoV1 has the highest sequence identity (86.88%) to Bremia lactucae associated ourmia-like virus 2 (BlaOLV2). Phylogenetic analysis revealed that VdMoV1 is a new member of the genus Magoulivirus. As far as we know, VdMoV1 is the first reported member of the family Botourmiaviridae infecting V. dahliae.
