摘要: 针对转cry1Ab/cry1Ac基因抗虫水稻(Oryza sativa L.)TT51-1及其回交后代中外源基因的检测建立了一种三引物多重PCR检测方法。结果表明,三引物PCR体系可以准确区分cry1Ab/cry1Ac基因纯合、杂合和阴性三种基因型,纯合体中只扩增出一条298 bp片段,阴性材料中只扩增出一条787 bp片段,杂合体中同时扩增出298 bp片段和787 bp片段。该体系的建立为利用TT51-1进行抗螟虫水稻分子育种提供了一个简便有效的基因鉴定技术。

Abstract: A tri-primer multiplex PCR method was established for the detection of cry1Ab/cry1Ac gene in the cry1Ab/cry1Ac transgenic rice TT51-1 and its backcross progenies of Huahui No.1. According to the foreign gene sequence inserted in TT51-1 and the rice genome sequence on the left and right sides of the insertion site, three PCR primers P1, P2 and P3 were designed. The results showed that the three primers PCR system could accurately distinguish the homozygous, heterozygous and negative genotypes of cry1Ab/cry1Ac gene. Only one 298 bp fragment was amplified in homozygote and only one 787 bp fragment was amplified in negative materials. Both 298 bp and 787 bp fragments were amplified from the heterozygote. The establishment of this system provides a simple and effective gene identification technique for molecular breeding of borer-resistant rice using TT51-1.
