摘  要：
建立高效的目的基因检测方法是保障生物育种研发和产业化进程的重要技术支撑。应用常规PCR法、TaqMan探针实时荧光PCR法及叶片直接PCR法对转基因玉米叶片进行Ca MV35S启动子和NOS终止子2个转基因元件的检测。结果表明,叶片直接PCR法分别较常规PCR方法和TaqMan探针实时荧光PCR法节约62%、48%的时间和25%、43%的成本,而且扩增出的目的条带清晰可见,符合目的片段大小,结果真实可靠,适用于大量转基因玉米植株叶片的快速筛选和鉴定。

摘  要：
An efficient target gene detection method is an important technical support to ensure the development and industrialization of biological breeding. In this study, conventional PCR method, TaqMan probe real-time fluorescence PCR method and leaf direct PCR method were used to detect two transgenic elements of CaMV35 S promoter and NOS terminator in leaves of transgenic maize plants. The experiment results showed that the leaf direct PCR method saved 62% and 48% time and reduced 25% and 43% cost compared with the conventional PCR method and TaqMan probe real-time fluorescence PCR method, respectively, and the amplified target band was clearly visible, and the fragment size was in accord with the target fragment size. The results were true and reliable,which was suitable for rapid screening and identification of a large number of transgenic maize leaves.
