Abstract
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.
