摘要
从制备的番茄花叶病毒(ToMV- S1) 抗血清中提纯IgG,并用过碘酸钠法进行辣根过氧化物酶(HRP) 标记,建立了检测ToMV 的DAS- ELISA 系统。利用此检测系统并结合生物学方法,对浙江及山西等地的田间病样进行测定,结果发现茄子、番茄等茄科作物中均有ToMV 的侵染,其中茄子中有50 % 左右的发生率,番茄中ToMV 发生率南北差异较大, 在浙江发生率仅为10 % 左右,而在山西有60 .7 % 的发生率,辣椒中未测到ToMV。这是在我国首次进行ToMV
Immunoglobulin (IgG) of ToMV antiserum was purified and conjugated with horseradish peroxidase (HRP) by sodium periodate. A DAS-ELISA method for ToMV detection was developed using the conjugant. Some field samples of Solanaceae collected from Zhejiang and Shanxi Provinces were detected by DAS-ELISA and biological tests, results showed that ToMV was a common pathogen of tomato and eggplant. About 50% of detected Solanum melongena samples had ToMV both in Zhejiang and Shanxi provinces.However,there was a significant difference between tomato samples from Zhejiang and Shanxi provinces.In Zhejiang province, only about 10% of samples were infected by ToMV, while the numbers of infected samples were above 60% in Shanxi. No sample was found infected by ToMV in Capsicum annum . This is the first report about the field survey of ToMV in China.
