Tobacco rattle virus (TRV) is a pathogenic plant virus. Over 400 species of plants from 50 families are susceptible to infection.〔(''Paratrichodorus minor''. ) Nemaplex. University of California, Davis.〕 The virus causes the plant disease tobacco rattle in many plants, including many ornamental flowers〔(Tobacco Rattle. ) Wisconsin Horticulture. University of Wisconsin Extension. 2010.〕 including ''Narcissus''. It causes the disease corky ringspot 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.〔 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.〔 The virus can also be spread on garden tools. It can also be mechanically and seed transmitted.〔 ==Hosts and Symptoms== Boning 〔Characterization and vector relation of a serologically distinct isolate of tobacco rattle tobravirus (TRV) transmitted by Trichodorus similis in northern Greece.

It was discovered in ''Nicotiana tabacum'', which is a species of cultivated tobacco. Tobacco Rattle Virus is common and potentially serious in a variety of herbaceous ornamentals including, but not limited to, astilbe, bleeding heart, coral bells, daffodil, epimedium, gladiolus, hyacinth, marigold, tulip and vinca. Tobacco rattle can also affect vegetable crops such as beans, beets, peppers, potatoes, and spinach. On potatoes, the disease is referred to as corky ring spot. The disease corky ringspot of potatoes was first reported in the United States in 1946, and was identified incorrectly as a novel virus until advances in genetics demonstrated it to be the result of TRV.〔〔Wernette, Loren G. "Potato Nematode Research: With Special Reference to Potato Early-Die, Corky Ringspot, and Soil Enzymes." MSU.edu. Michigan State University Entomology Department, 2011. Web. 20 Oct. 2014.〕 Symptoms of Tobacco Rattle Virus vary based on the plant host, which differs widely in this disease. Common symptoms include mottling, cholortic or necrotic local lesion, ringspots or line patterns, and systemic necrosis. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tobacco rattle virus」の詳細全文を読む スポンサード リンク
