Group:	Group IV ((+)ssRNA)
Family:	Potyviridae

Potyviruses infect plants and belong to the family Potyviridae. The virion is non-enveloped, the nucleocapsid is filamentous and is 11-20 nm in diameter. The genome is a linear positive sense ssRNA. The genome ranges in size from 9000-12000nt. Replication occurs in the cytoplasm.

Species include:

• Malva vein clearing potyvirus
• Potato virus Y (type species)
• Turnip mosaic virus
• Plum Pox Potyvirus
• Tulip breaking virus
• Papaya ringspot virus
• Apium virus Y
