Abstract

Reverse-transcribing viruses, which synthesize a copy of genomic DNA from an RNA template, are widespread in animals, plants, algae and fungi .…The ICTV has recently regrouped the families Belpaoviridae, Caulimoviridae, Metaviridae, Pseudoviridae and Retroviridae into an order Ortervirales (orter: an inversion of retro, which was derived from reverse transcription; virales: suffix for an order). This change in taxonomy acknowledges and formalizes the long-proposed evolutionary relationship among most groups of reverse-transcribing viruses. We note that although hepadnaviruses are not included in the order, they might be unified with other reverse-transcribing viruses at a higher taxonomic level in the future.
