Abstract
- Stagonosporopsis cucurbitacearum is an important plant-pathogenic fungus that causes stem and leaf blight diseases in a variety of crops. Here, we report the characterization of a novel victorivirus, tentatively named "Stagonosporopsis cucurbitacearum victorivirus 1" (ScVV-1), isolated from the S. cucurbitacearum isolate M-7. The ScVV-1 genome is 5,165 bp in length with a predicted GC content of 60.1% and contains two large open reading frames (ORF 1 and ORF2) encoding putative proteins that share significant sequence similarity with coat proteins (CPs) and RNA-dependent RNA polymerases (RdRps) of mycoviruses of the family Totiviridae. The ScVV-1 RdRp appears to be translated using a stop-initiation pentanucleotide UAAUG sequence. Phylogenetic analysis based on CP and RdRp amino acid (aa) sequences both indicated that ScVV-1 belongs to the genus Victorivirus in the family Totiviridae. To our knowledge, this is the first full-length genome sequence of a victorivirus infecting S. cucurbitacearum. [ABSTRACT FROM AUTHOR]
