|Potato (Solanum tuberosum) is the fourth important food resources in the daily food chain which was affected by several pathogenic agents including viruses, resulting a significant diminution in yield production worldwide. Despite the presence of a broad spectrum of diverse deleterious viruses, the most common and economic ones are Potato virus A, Potato virus Y (PVA, PVY, both from genus Potyviruses), Potato leafroll virus (PLRV, genus Polerovirus), Potato virus X (PVX, genus Potexvirus) and Potato virus S (PVS, genus Carlavirus). Viruses of the family Luteoviridae belongs to ssRNA plant viruses, divided into three genera: Enamovirus, Luteovirus and Polerovirus. Members of this family infect a broad range of mono- and dicotyledonous plants that they exclusively replicate in the phloem tissue . PLRV infects potato plants, causing economic losses on the yield. PLRV causes characteristic rolling of leaves, chlorosis and stunting of infected plants. In a number of cultivars, PLRV also causes a dark discoloration of the tubers so-called 'net necrosis' that refers to a selective death and damage of cells in the phloem tissue of tubers.
