Characteristics related to biosafety
Centre(s) of origin
PLRV was first described by Quanjer et al. in 1916.
Habitat range
Because PLRV is transmitted by aphid vectors it is more prevalent in environments that are conducive to aphid development. Warm humid conditions are preferred, but aphids can thrive in a number of climates as long as it is not too hot and dry, as their soft bodies make them prone to desiccation. In the tropics, aphids persist year round but the efficiency of PLRV transmission is reduced at temperatures above 26 degrees Celsius. The optimal temperatures for the green peach aphid are between 13 and 19 degrees Celsius.
Known pathogenicity and/or allergenicity
Plants that are infected with the virus produce only small to medium tubers that are not preferable in market. When plants are grown from infected tubers yield can be reduced 33-50%. Since potatoes are produced by planting the tubers produced the previous season, PLRV is especially problematic in seed potato production. Plantings from infected tubers will not yield acceptable market quality potatoes and can cause a significant loss.
