Abstract
- Nematodes are abundant, but little is known about their viruses. In this study, we report a novel partitivirus isolated from the entomopathogenic nematode species Steinernema ceratophorum, named "Steinernema ceratophorum partitivirus 1" (ScPV-1). The complete genome of ScPV-1 comprises two dsRNA segments, dsRNA1 (2352 bp) and dsRNA2 (2196 bp). Each dsRNA contains a single open reading frame (ORF), encoding a putative RNA-dependent RNA polymerase (RdRp) and a coat protein (CP), respectively. The sequences of the RdRp and CP showed the highest similarity (47% and 33% identity, respectively) to Plasmopara viticola associated partitivirus 7 (PvAP-7). A multiple sequence alignment and phylogenetic analysis of the RdRp of ScPV-1 and other selected viruses indicated that ScPV-1 is a new member of the genus Betapartitivirus in the family Partitiviridae.
