A novel double-stranded RNA (dsRNA) mycovirus, designated Magnaporthe oryzae partitivirus 1 (MoPV1), was isolated from a strain of the plant pathogenic fungus Magnaporthe oryzae. The MoPV1 genome has two dsRNA genome segments. The larger segment (1763 bp) has a single open reading frame (ORF) with a conserved RNA-dependent RNA polymerase (RdRp) domain. The smaller segment (1491 bp) contains a single ORF encoding a putative coat protein (CP). Homology searches and phylogenetic analysis indicated that MoPV1 is a new member of the genus Gammapartitivirus. This is the first report of a mycovirus of the family Partitiviridae identified in Magnaporthe oryzae.
从植物病原真菌稻瘟病菌的一个菌株中分离出一种新型双链RNA（dsRNA）真菌病毒，命名为稻瘟病菌分体病毒1（MoPV1）。MoPV1基因组有两个dsRNA基因组片段。较大的片段（1763 bp）有一个单一的开放阅读框（ORF），带有一个保守的RNA依赖RNA聚合酶（RdRp）结构域。较小的片段（1491 bp）包含一个单一的ORF，编码一种假定的外壳蛋白（CP）。同源性搜索和系统发育分析表明，MoPV1是γ-分体病毒属的一个新成员。这是在稻瘟病菌中鉴定出的分病毒科真菌病毒的首次报道。
