本文测定了立枯丝核菌SM03分离株中一种新的真菌病毒SM03的全基因组序列，命名为“立枯丝核菌部分病毒SM03”(RSPV-SM03)。RSPV-SM03基因组由两个dsRNA组成(dsRNA-1和dsRNA-2)，每个dsRNA含有一个开放阅读框架(ORF)。DsRNA-1的ORF1编码依赖于RNA的RNA聚合酶(RdRp)，dsRNA-2的ORF2编码病毒外壳蛋白(CP)。系统进化分析表明，RSPV-SM03的RdRp和CP与甲型副病毒科甲病毒属其他成员的RdRp和CP有较近的亲缘关系，表明RSPV-SM03是甲型病毒属的一个新种。
In this report, the full genome sequence of a novel mycovirus, designated as "Rhizoctonia solani partitivirus SM03" (RsPV-SM03), was determined inRhizoctonia solaniAG-4 HG III isolate SM03. RsPV-SM03 genome consists of two dsRNAs (dsRNA-1 and dsRNA-2), each of them contains one single open reading frame (ORF). ORF1 of dsRNA-1 encodes a putative RNA-dependent RNA polymerase (RdRp), while ORF2 of dsRNA-2 encodes a putative viral coat protein (CP). Phylogenetic analysis indicated that the RdRp and CP of RsPV-SM03 are closely related to those of other members of the genusAlphapartitivirus, familyPartitiviridae, suggesting that RsPV-SM03 represents a novel species in the genusAlphapartitivirus.
