In this study, we describe the genome sequence of a novel double-stranded RNA (dsRNA) mycovirus, designated as "Rhizoctonia solani partitivirus 15" (RsPV15), from the phytopathogenic fungus Rhizoctonia solani. RsPV15 consists of two genomic double-stranded RNA segments, dsRNA-1 and dsRNA-2, which are 2433 bp and 2350 bp long, respectively. Each of the dsRNA segments contains a single open reading frame, encoding the putative RNA-dependent RNA polymerase and coat protein, respectively. Homology searches and phylogenetic analysis suggested that RsPV15 is a new member of the genus Betapartitivirus within the family Partitiviridae.
在这项研究中，我们描述了一种新型双链 RNA (dsRNA) 真菌病毒的基因组序列，该病毒命名为“Rhizoctonia solani partitivirus 15”（RsPV15），来源于植物病原菌 Rhizoctonia solani。RsPV15 由两个基因组双链 RNA 片段组成，dsRNA-1 和 dsRNA-2，分别长 2433 个和 2350 个碱基。每个 dsRNA 片段包含一个单一的开放阅读框，分别编码假定的 RNA 依赖性 RNA 聚合酶和外壳蛋白。同源搜索和系统发育分析表明，RsPV15 是 Partitiviridae 科 Betapartitivirus 属的一个新成员。
