- 摘要:
- 利用田间表型鉴定和 PCR检测相结合的方法, 对从美国引进的 46 个大豆品种进行了转基因成分的检测。实验过程中, 首先通过喷洒草甘膦对待测材料进行表型鉴定 ,然后通过 PCR分子检测分析 CaMV35S 启动子和 NOS 终止子的有无, 初步判定引进材料是否为转基因大豆, 最后对目的基因 CP4 - EPSPS 进行检测 ,进一步确定所测材料是否为抗草甘膦转基因大豆 。大豆本身的凝集素基因作为 PCR 检测的内置检测标准, 有效排除了由于 DNA 质量 、实验操作等因素对检测结果的影响 。结果表明, 在所检测的 46 个引进品种中 ,5 个是抗草甘膦转基因品种 ,41 个是非转基因品种 ,它们可作为我国大豆新品种选育的亲本材料。
- Abstract:
- In the present study , both field screening and PCR detection were conducted to identify thetransgenic elements in 46 accessions of introduced America soybean varieties. First , the introduced varie-ties were screened by foliar spaying of glyphosate at lethal concentration in the field;Secondly , CaMV35Spromoter , NOS terminator and lectin genes were examined by using PCR to determine if these lines weregenetically modified;Finally , CP4- EPSPS and lectin genes were amplified with PCR to determine if theywere glyphosate - resistant transgenic soybeans. The lectin gene of soybean itself was used as internalstandard to exclude the interference of DNA quality and experimental operation problems. Among the for-ty - six introduced America soybean varieties, five were found to be glyphosate - resistant and transgenic,and other forty - one were nontransgenic. The latter can be used as parents in soybean breeding program indifference regions of China.
