Tobacco etch virus (TEV) and potato virus Y (PVY), are two common tomato viruses in some areas of southern United States and in Central America. TEV has been recovered from infected tomatoes in New York; infections with PVY have probably occurred. but have not been reported. The symptoms of TEV and PVY can be confused with TMV. Because some varieties carry partial resistance to TMV and none. Potato virus X (PVX) is a plant pathogenic virus of the family Alphaflexiviridae and the order Tymovirales. PVX is found mainly in potatoes and is only transmitted mechanically. There are no insect or fungal vectors for this virus. This virus causes mild or no symptoms in most potato varieties, but when Potato virus Y is present, synergy between these two viruses causes severe symptoms in. Potato virus Y (PVY), pepper mottle virus (PeMV), and TEV occur more regularly in the southern states. How some of these viruses reach the northern states is unclear. They may move north via migrant aphids, which carry the viruses progressively northward, passing them from one susceptible crop to another along the Atlantic coast.

PVY infects other solanaceous crops including tomato and capsicum Potato Virus Y (PVY, genus Potyvirus, family potyviridae) is widely distributed in the potato growing areas worldwide and is the most important virus affecting Scottish potatoes. PVY is transmitted non-persistently by non-colonising aphid vectors (Figure 1), resulting in rapid acquisition and transmission of the virus. In 2009 PVY accounted for approximately 55% of all viruses found within the. Potato virus Y is widespread and occurs more or less seriously on all continents. Europe is particularly affected by this virus, with very aggressive necrotic strains reported in Eastern Europe (Hungary, Bulgaria and Poland), and Western Europe (Spain, Italy and France). In Asia necrotic strains occur as well. They have been reported in China, Japan, Korea and Taiwan. Several African countries are affected, and PVY seems a rather serious problem in North Africa, particularly in Morocco. On.

Potato virus Y (PVY) continues to be an economically important pathogen of potato (Solanum tuberosum L.), worldwide, that causes significant yield losses and is detrimental to quality of tubers [1,2,3].PVY belongs to the family Potyviridae, and genus Potyvirus. It is a flexuous rod-shaped virus which exhibits a 9.7 kb + ss RNA genome [] Plant viruses such as PVY are incapable of move-ment on their own. The two most common methods of PVY movement are by aphid vectors and mechanical transmission. During mechanical transmission (also called sap transmission), PVY is spread by contact between infected and healthy plants resulting in short-distance spread of the virus. This transmis- sion requires a wound, which can be caused by. this widespread virus. PVY is a Potyvirus, the type member of the largest group of plant viruses. It is transmitted by aphids in a nonpersistent manner, by sticking to aphid mouthparts (stylet). The virus can be acquired from the infected plant within seconds, and transmitted to a healthy plant just a

PVY inoculum was traced to seed lots imported from other states with less stringent virus limits, and infection probably increased via neglected cull piles of infected seed and in fields planted with the PVY-symptomless cultivar Russet Norkotah. During the epidemic, studies showed that PVY infection of indicator plants in the field correlated with the peak flight of aphids from common crops. potato virus Y (PVY; all strains) and potato leafroll virus (PLRV) with real-time PCR. Viral RNA, extracted from potato samples, is amplified in a one-step RT-PCR reaction. The amplification of the cDNA can be monitored in real time, because the spe-cific probes are labeled with fluorophores (PVY: FAM and PLRV: Cy5). An internal control (IC: JOE) is included for the conve-nience of the. Potato virus Y (PVY) is the most important member of the Potyvirus genus (Potyviridae fam-ily) infecting potatoes. PVY is easily transmitted mechanically and by many aphid species in a non-persistent manner (Brunt 2001). Various PVY strains can cause yield losses from 10 to 90% and decrease plant productivity or tuber quality (Brunt 2001; Novy et al. 2002). Breeding of resistant cultivars is.
