Seven dsRNA segments were detected from a single Rhizoctonia solani strain HG81. From the full-length cDNA sequences of four smaller dsRNA segments, the genomes of two related partitiviruses, designated as Rhizoctonia solani partitivirus 3 (RsPV3) and RsPV4, were determined. The genomes of RsPV3 and RsPV4 are both composed of two separate dsRNA segments, with each segment possessing a single open reading frame (ORF). ORF1 from RsPV3 and RsPV4 encodes a putative RNA-dependent RNA polymerase, while ORF2 of RsPV3 and RsPV4 encodes a putative capsid protein. RsPV3 and RsPV4 share high sequence identity with viruses classified within the genus Alphapartitivirus, family Partitiviridae.
从单一立枯丝核菌菌株HG81中检测到7条双链RNA片段。根据4条较小双链RNA片段的全长cDNA序列，确定了两种相关的分体病毒的基因组，分别命名为立枯丝核菌分体病毒3（RsPV3）和RsPV4。RsPV3和RsPV4的基因组均由两个独立的双链RNA片段组成，每个片段都有一个单一的开放阅读框（ORF）。RsPV3和RsPV4的ORF1编码一个假定的RNA依赖性RNA聚合酶，而RsPV3和RsPV4的ORF2编码一个假定的衣壳蛋白。RsPV3和RsPV4与分病毒科α-分病毒属内分类的病毒具有高度的序列同一性。
