摘要: 转基因抗虫耐除草剂玉米GH5112E-117C是由北京奥瑞金公司研发的转mG2-aroA基因和mcry1Ah基因抗虫耐除草剂玉米新品系,对玉米螟、粘虫等鳞翅目害虫具有抗性、耐草甘膦除草剂的转基因玉米,在我国具有重要产业化应用前景。本文研发了GH5112E-117C转基因玉米的定性PCR检测方法,该方法能特异性地检测转基因抗虫耐除草剂玉米GH5112E-117C,在每个反应引物浓度为0.2 μmol/L、Taq DNA 聚合酶0.625 U、DNA模板50 ng,退火温度为58℃的条件下,检测灵敏度可稳定达到0.1%。该方法为转基因抗虫耐除草剂玉米GH5112E-117C的精准检测提供了一种新的技术手段,为农业转基因监管提供技术支撑。

Abstract: Transgenic maize GH5112E-117C is a new strain with mG2-aroA gene and mcry1Ah genes and developed by Beijing Origen Company. It is resistant to lepidopteran pests such as corn borer and armyworm,and it is tolerant to glyphosate- herbicide. Thus this strain has important industrial application prospects in China. A qualitative PCR assay for transgenic maize GH5112E-117C was developed in this paper. The assay had promising specificity to detect the transgenic maize GH5112E-117C with resistance to insects and tolerance to herbicide. At a concentration of 0.2 μmol/L primer,TaqDNA polymerase 0.625 U,DNA template 50 ng,and an annealing temperature of 58℃,the detection sensitivity of the assay stably achieved to 0.1%. This assay provides a new technical means for accurately testing insect- and herbicide-resistant transgenic maize GH5112E-117C,which provides the technical support for transgenic supervision in agriculture.
