    Abstract:
    Here, we report the occurrence and complete genome sequence of a novel victorivirus infecting Metarhizium anisopliae, named "Metarhizium anisopliae victorivirus 1" (MaVV1). The genome is 5353 bp in length and contains two open reading frames (ORFs), encoding a coat protein and an RNA-dependent RNA polymerase (RdRp), that overlap at the octanucleotide sequence AUGAGUAA. These ORFs showed sequence similarity to the corresponding ORFs of Ustilaginoidea virens RNA virus L (68.23%) and Ustilaginoidea virens RNA virus 13 (58.11%), respectively, both of which belong to the family Totiviridae. Phylogenetic analysis based on RdRp sequences revealed that MaVV1 clustered with members of the genus Victorivirus. This is the first genome sequence reported for a virus belonging to the genus Victorivirus infecting the entomopathogenic fungus M. anisopliae.
