A novel positive-sense single-stranded RNA mycovirus, designated as "Magnaporthe oryzae botourmiavirus 10" (MoBV10), was identified in the rice blast fungus Magnaporthe oryzae isolate HF04. MoBV10 has a single genomic RNA segment consisting of 2,448 nucleotides, which contains a single open reading frame encoding an RNA-dependent RNA polymerase. Genome comparison and phylogenetic analysis indicated that MoBV10 is a new member of the genus Betascleroulivirus in the family Botourmiaviridae. The 5'- and 3'-terminal sequences of the genomic RNA of MoBV10 have inverted complementarity and potentially form a panhandle structure, which is very rare in RNA viruses.
一株新型正链单链 RNA 真菌病毒，命名为“稻瘟病菌博图米亚病毒 10 型”（MoBV10），在稻瘟病菌分离株 HF04 中被鉴定出来。MoBV10 有一个由 2448 个核苷酸组成的单基因组 RNA 片段，其中包含一个编码 RNA 依赖的 RNA 聚合酶的单一开放阅读框。基因组比较和系统发育分析表明，MoBV10 是博图米亚病毒科贝塔鲨状病毒属的一个新成员。MoBV10 基因组 RNA 的 5'-和 3'-末端序列具有反向互补性，并可能形成一个铲形结构，这在 RNA 病毒中非常罕见。
