Potato leafroll virus

Potato leafroll virus (PLRV) is a member of the genus Polerovirus and familySolemoviridae. The phloem limited positive senseRNA virus infects potatoes and other members of the family Solanaceae. PLRV was first described by Hendrik Marius Quanjeret al. in 1916. PLRV is transmitted by aphids, primarily the green peach aphid, Myzus persicae. PLRV is one of the most important potato viruses worldwide but particularly devastating in countries with limited resources and management. It can be responsible for individual plant yield losses of over 50%. One estimate suggests that PLRV is responsible for an annual global yield loss of 20 million tons. Symptoms include chlorosis, necrosis and leaf curling.
