Plant viruses in the new 15-rank taxonomic system of ICTV

This article reports the new taxonomy system (2019) approved by the International Committee on Taxonomy of Viruses (ICTV) in March 2020, which fully adopted a 15-rank taxonomic structure, namely: realm, subrealm, kingdom, subkingdom, phylum, subphylum, class, subclass, order, suborder, family, subfamily, genus, subgenus, species. Viruses whose hosts are plants include plant viruses and subviral infection factors (satellite virus, satellite and viroid). There are 1 608 species of plant viruses, belonging to 2 realms, 3 kingdoms, 8 phyla, 13 classes, 16 orders, 31 families, 8 subfamilies, 132 genera and 3 subgenera. Subviral infection factors include 33 species of viroids belonging to 2 families and 8 genera, 6 species of satellite viruses belonging to 4 genera, and 142 species of satellites belonging to 2 families, 2 subfamilies and 13 genera.
