Abstract
Here, we describe the full-length genome sequence of a novel ourmia-like mycovirus, tentatively named “Botryosphaeria dothidea ourmia-like virus 1” (BdOLV1), isolated from the phytopathogenic fungus Botryosphaeria dothidea strain 8A, associated with apple ring rot in Shanxi province, China. The complete BdOLV1 genome is comprised of a 2797-nucleotide positive-sense (+) single-stranded RNA (ssRNA) with a single open reading frame (ORF). The ORF putatively encodes a 642-amino-acid polypeptide with conserved RNA-dependent RNA polymerase (RdRp) motifs related to those of viruses of the family Botourmiaviridae. Phylogenetic analysis based on RdRp amino acid sequences showed that BdOLV1 is grouped with unclassified oomycete-infecting viruses closely related to members of the genus Botoulivirus in the family Botourmiaviridae. This is the first report of a novel (+)ssRNA virus in B. dothidea related to members of the genus Botoulivirus in the family Botourmiaviridae.
