Sweet potato feathery mottle virus (SPFMV) is a member of the family Potyviridae, genus Potyvirus. It is most widely recognized as one of the most regularly occurring causal agents of Sweet Potato Viral Disease (SPVD) and is currently observed in every continent except Antarctica. The number of locations where it is found is still increasing; generally, it is assumed that the virus is present wherever its host is. The virus has four strains that are found in varying parts of the world.〔 ==History== SPFMV was initially discovered in the United States 70 years ago, and currently, it is the most widely spread sweet potato virus in the world.〔 The presence of this virus is usually indicated by the presence of sweet potato viral disease, as it is noticed less often on its own. SPFMV was more recently discovered in Italy as the primary contributor to Italian SPVD.〔
