- Abstract
Alternaria brassicicola is one of the causal agents of alternaria blackspot in rapeseed. In this study, a dsRNA segment was isolated and sequenced from the fungus. The complete nucleotide sequence of the dsRNA was 2506 bp in length and, using the fungal mitochondrial genetic code, was predicted to contain a single large open reading frame (ORF) in the positive strand. This ORF was predicted to encode a protein with 719 amino acids that contains characteristic conserved motifs of the RNA-dependent RNA polymerase (RdRp). BLAST analysis revealed that this protein had significant sequence similarity to the RdRp from viruses of the genus Mitovirus. These results indicated that the dsRNA segment represents the replicative form of a mitovirus, which is tentatively designated 'Alternaria brassicicola mitovirus 1' (AbMV1) and is a new member of the genus Mitovirus in the family Narnaviridae.
