The Picornavirales are an order of viruses with vertebrate, insect, and plant hosts. This group consists of viruses which have positive-sense single-stranded RNA genomes.
Five families within this group—Caliciviridae, Dicistroviridae, Picornaviridae, Potyviridae and Sequiviridae share a number of common features:
The evolution of these viruses may have preceded the separation of eukaryotes into the extant crown groups.
The taxonomy of this group has been reorganised by the ICTV in 2011. The Caliciviridae and the Potyviridae have been removed from this order. The Bacillariornaviridae, the Labyrnaviridae, and the Sequiviridae have been reduced to genera.
