"Paraxenoviridae", a putative family of ubiquitous marine bacteriophages with double-stranded RNA genomes.

ABSTRACT: Fragmented and primer Ligated DsRNA Sequencing (FLDS) was used to reconstruct five complete, bisegmented RNA genomes of paraxenoviruses, a group of viruses that was previously identified in the ocean and that based on the analysis of partial genomes was proposed to represent a putative new phylum within the kingdom Orthornavirae of the realm Riboviria. Phylogenetic analysis of the RNA-directed RNA polymerases of paraxenoviruses demonstrated their affinity with the ribovirus order Durnavirales within the class Duplopiviricetes of the phylum Pisuviricota. The order Durnavirales includes families Cystoviridae that consists of well-characterized dsRNA bacteriophages and less thoroughly studied Picobirnaviridae that are also suspected to i
