Abstract Background RNA viruses have been isolated that infect marine organisms ranging from bacteria to whales but little is known about the composition and population structure of the in situ marine RNA virus community. In a recent study the majority of three genomes of previously unknown positive-sense single-stranded ss RNA viruses were assembled from reverse-transcribed wholegenome shotgun libraries. The present contribution comparatively analyzes these genomes with respect to representative viruses from established viral taxa. Results Two of the genomes JP-A and JP-B appear to be polycistronic viruses in the proposed order Picornavirales that fall into a well-supported clade of marine picorna-like viruses the characterized members of which all infect .
