Abstract
In this study, we report the molecular characterization of a novel mycovirus in a phytopathogenic fungus of the species Colletotrichum gloeosporioides, which we named “Colletotrichum gloeosporioides RNA virus 1” (CgRV1). The virus has a dsRNA genome of 2,975 bp and possesses two non-overlapping open reading frames (ORFs 1 and 2). The smaller ORF1 encodes a protein of unknown function, and the larger ORF2 encodes the RNA-dependent RNA polymerase (RdRp). Phylogenetic analysis based on the RdRp sequence showed that CgRV1 clustered with and is closely related to unclassified mycoviruses that are distinct from members of the family Partitiviridae.
