Abstract
In this study, we described the occurrence and complete genome of a novel Victorivirus infecting Metarhizium anisopliae, named “Metarhizium anisopliae victorivirus 1” (MaVV1). The genome is 5,353 bp in length and contains two ORFs, encoding a Coat Protein and an RNA-dependent RNA-polymerase (RdRp), which are overlapped in an octanucleotide (AUGAGUAA). Among characterized viruses, the identified ORFs showed similarity with Ustilaginoidea virens RNA virus L (68.23%) and Ustilaginoidea virens RNA virus 1 (58.11%), both belonging to Totiviridae family. Phylogenetic analysis based on RdRp sequences revealed the MaVV1 placement in the Victorivirus genus. This is the first genome sequence report of a virus belonging to the genus Victorivirus infecting the entomopathogenic fungus M. anisopliae.
