Potyvirus is a genus of positive-strand RNA viruses (named after its type species, Potato virus Y (Potyvirus yituberosi, PVY)) in the family Potyviridae. Plants serve as natural hosts. Like begomoviruses, members of this genus may cause significant losses in agricultural, pastoral, horticultural, and ornamental crops. More than 200 species of aphids spread potyviruses, and most are from the subfamily Aphidinae (genera Macrosiphum and Myzus). The genus contains 190 species and potyviruses account for about thirty percent of all currently known plant viruses.
