Revtraviricetes

Revtraviricetes is a class of viruses that contains all viruses that encode a reverse transcriptase.^[1] The group includes all ssRNA-RT viruses (including the retroviruses) and dsDNA-RT viruses. It is the sole class in the phylum Artverviricota, which is the sole phylum in the kingdom Pararnavirae.^[2] The name of the group is a portmanteau of "reverse transcriptase" and -viricetes which is the suffix for a virus class.^[1]
