And CaMV35S promoter, Nos terminator and cry1Ac or cry1Ab or cry1Ac and cry1Ab fusion gene were not amplified in the negative control, but successfully amplified in the positive control and the sample 1, which indicated sample 1 was transgenic cotton.

• CaMV35S启动子,Nos终止子、cry1Ac基因、cry1Ab基因、以及cry1Ac与cry1Ab融合基因序列在阴性对照没有得到扩增,在阳性对照和1号试样中都得到了扩增,且扩增片段大小与预期片段大小一致, 表明所检测的样品是转基因棉花种子,并且来自转Bt基因棉花。
