用RT-PCR技术检测澳大利亚杏仁树李坏死坏斑病毒,对92个待测样品的病毒RNA进行扩增和检测,其中有79个呈阳性,表明检验样品的染病率较高.RT-PCR技术检测病毒的方法灵敏、准确,是检测苗木是否感染病毒的有效方法之一. RT-PCR was used to detect the necrotic virus in almond tree in Australia, and the viral RNA in 92 samples were amplified and tested, of which 79 were positive, indicating that the test samples were highly infected. RT-PCR The method of detecting virus is sensitive and accurate, and it is one of the effective methods to detect whether the seedlings are infected with the virus.
