ABSTRACT
Bipolaris maydis is the causal agent of corn southern leaf blight. Here, we report a novel double-stranded RNA (dsRNA) mycovirus designated Bipolaris maydis botybirnavirus 1 (BmBRV1) from B. maydis strain JZ11 in Jingzhou, Hubei province of China. BmBRV1 has a genome consisting of two dsRNAs (dsRNA1 and dsRNA2) with a size of 6435 and 5987 bp, respectively, each of which contains a single open reading frame (ORF). The two polyproteins encoded by dsRNA1 and dsRNA2 share the highest amino acid identities of 81.8 and 75.3%, respectively, with the RdRp and coat protein of Sclerotinia sclerotiorum botybirnavirus 1 (SsBRV1), a tentative species of the genus Botybirnavirus. Phylogenetic analysis based on the amino acid sequences of RdRp indicated that BmBRV1 belongs to a distinct species of the newly proposed family Botybirnaviridae.
