Potato leafroll virus (PLRV) is a member of the genus Polerovirus and family Solemoviridae. The phloem limited positive sense RNA virus infects potatoes and other members of the family Solanaceae. PLRV was first described by Quanjer et 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.

  • El enrollamiento de la hoja de la papa es una enfermedad causada por el virus PLRV (Potato Leafroll Virus), perteneciente a la familia . De las virosis de la papa esta enfermedad es la más importante y se encuentra en todas las regiones donde se cultiva la papa en elmundo. Las pérdidas que causa en el rendimiento pueden alcanzar el 90% en cultivares altamente susceptibles al ataque del virus. (es)

  • Die Blattrollkrankheit bei der Kartoffel wird verursacht durch das Blattrollvirus (PLRV, Potato leafroll virus, Gattung , Familie Luteoviridae). Es verursacht ein Einrollen der oberen Blätter, ein helleres Laub und steileren Wuchs. Durch Assimilatestau in den Siebröhren, der Abtransport der Stärke ist aufgrund des Befalls in den Gefäßen gehemmt, werden die Blätter hart und brüchig. PLRV war bis Ende der 1980er Jahre die bedeutendste Viruskrankheit im Kartoffelbau. Infektionen finden ausschließlich über Vektoren statt. Das Virus wird von den Blattläusen aus dem Siebröhrenbereich entnommen, gelangt in den Verdauungstrakt und wird durch die Speicheldrüsen wieder abgegeben. Für die Infektion einer Kartoffelpflanze ist ein Saugvorgang von mindestens zwei Stunden notwendig. Einmal infizierte Blattläuse sind lebenslang Überträger. Das deutsche Sortenspektrum weist große Unterschiede in der Anfälligkeit der Sorten auf, die meisten Sorten sind jedoch mittel anfällig bis anfällig. (de)
