烟草环斑病毒(Tobacco ringspot virus,TRSV)为豇豆花叶病毒科(Comoviridae)线虫传病毒属(Nepovirus)的典型成员。TRSV寄主范围广泛,可为害54科246种草本和木本植物,在许多重要农作物如大豆、烟草上为害严重。TRSV可引起大豆芽枯病,造成大豆产量损失达50%。TRSV可通过线虫、机械接种和种子等途径传播。种子传播是TRSV远距离传播的主要途径,大豆的种传率40%～100%[1]。TRSV既是我国进境植物检疫性有害生物。同时,也是全国农业植物检疫性有害生物,具有重要的经济意义。
Tobacco ringspot virus (TRSV) is a typical member of the genus Nepovirus of the genus Comoviridae. The TRSV host has a wide range of hosts that can damage 54 families, 246 species of herbs and woody plants, which are detrimental to many important crops such as soybeans and tobacco. TRSV causes soybean bacterial blight, resulting in a loss of soybean yield of up to 50%. TRSV can be transmitted by nematodes, mechanical inoculation and seeds. Seed propagation is the main route of TRSV transmission over long distances, and the seed transmission rate of soybean is between 40% and 100% [1]. TRSV is both a quarantine pest for entry into China. At the same time, it is also the national agricultural phytosanitary pest, which has important economic significance.
