Tobacco rattle virus (TRV) is a pathogenic plant virus. Over 400 species of plants from 50 families are susceptible to infection.[1]
The virus causes the plant disease tobacco rattle in many plants, including many ornamental flowers.[2] It causes the disease corky ringspot, or spraing, in potatoes. The disease manifests in various ways, and signs can include brown rings and arcs on the surface of a potato, and discolored spots on the interior.[1]
Nematodes of the family Trichodoridae, the stubby-root nematodes, are vectors of the virus. The nematode species Paratrichodorus minor, for example, introduces the virus when it feeds on the roots of plants.[1] The virus can also be spread on garden tools. It can be present in seeds, and cause disease in the plants that grow from them.[2]
