Abstract

We present a taxonomic proposal for revision of the family Secoviridae, a taxon of plant viruses in the order Picornavirales. We propose the reorganization of the genus Sadwavirus to create three new subgenera and to update the classification of five existing species. The proposed subgenera are “Satsumavirus” (one species: Satsuma dwarf virus), “Stramovirus” (two species: Strawberry mottle virus and Black raspberry necrosis virus) and “Cholivirus” (two species: Chocolate lily virus A and Dioscorea mosaic associated virus).
