Pisuviricota is a phylum of RNA viruses that includes all positive-strand and double-stranded RNA viruses that infect eukaryotes and are not members of the phyla Kitrinoviricota, Lenarviricota or Duplornaviricota. The name of the group is a syllabic abbreviation of "picornavirus supergroup" with the suffix -viricota, indicating a virus phylum. Phylogenetic analyses suggest that Birnaviridae and Permutotetraviridae, both currently unassigned to a phylum in Orthornavirae, also belong to this phylum and that both are sister groups.
Classification
The phylum contains the following classes:
Duplopiviricetes Mycopleornaviricetes Pisoniviricetes Stelpaviricetes Additionally, the order Yadokarivirales is unassigned to a class.
