Potyvirus
Sign in to savePotyvirus is a genus of positive-strand RNA viruses (named after 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 216 species.

Potyvirus is a genus of positive-strand RNA viruses (named after 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.

== Structure == The virion is non-enveloped with a flexuous and filamentous nucleocapsid, 680 to 900 nanometers (nm) long and is 11–20 nm in diameter. The nucleocapsid contains around 2000 copies of the capsid protein. The symmetry of the nucleocapsid is helical with a pitch of 3.4-3.5 nm.
