摘要: 芜菁花叶病毒(Turnip mosaic virus,TuMV)是侵染十字花科作物和观赏性物种的主要病害之一。利用反转录酶M-MLV和普通Taq酶,使用一步法多重RT-PCR技术,建立了一种快速、简便、特异性强的检测TuMV的方法。该方法简便,不需先对总RNA提纯,只需室温下在提取液中对病样叶片直接碾磨,用粗提液或浓缩后的DNA-RNA混合物为模板进行检测。2套针对TuMV的特异性引物确保了检测的准确性。

Abstract: Turnip Mosaic virus(Turnip Mosaic virus,TuMV)infects and causes damage in many crucifers and?ornamentals. Using of M-MLV and general Taq enzyme,we developed a rapid,convenience and specificity method?for detecting of TuMV by one-step multiple RT-PCR. This simple method didn't need the step of purification of total?RNA. After grinding the samples directly in extraction buffer at room temperature,the crude extract or concentrated?DNA-RNA mixture could be used as detection template. In order to ensure the accuracy of the detection,two sets of?primers were employed in this method.
