First Report of Red Rot of Jujube Fruit Caused by <i>Botryosphaeria dothidea</i> in China

Here, we describe a novel mycovirus, Botryosphaeria dothidea mitovirus 2 (tentatively designated as BdMV2), isolated from Botryosphaeria dothidea FJ strain causing pear ring rot disease in Fujian Province, China. The complete genome nucleotide sequence of BdMV2 is 2538 nt in length and contains a single 2070 nt open reading frame (ORF) encoding a putative RNA-dependent RNA polymerase (RdRp) of 689 amino acid (aa) using fungal mitochondrial genetic code. BLASTp analysis revealed that the RdRp of BdMV2 shares 28.91%-69.36% (query sequence coverage more than 90%) sequence identity to those of members in the genus Mitovirus, and the closest similarity is 69.36% and 68.79% with the corresponding protein aa sequences of Rhizoctonia solani mitovirus 10 and Macrophomina phaseolina mitovirus 4, respectively. Phylogenetic analysis based on the RdRp aa sequences further revealed that BdMV2 is a newly member in the genus Mitovirus of the family Narnaviridae. To our knowledge, BdMV2 is thus a novel mitovirus from the causal agent B. dothidea of pear ring rot disease.
