The Sequence and Detection of the cry1Aa Gene Expression Cassette in Transgenic Bt Cotton
摘要
Abstract
A new Bt gene expression cassette cry1Aa gene expression cassette was identified from transgenic insect-resistance cotton "Nannong 6 F1" in this study. The difference was found located at the connection region between Bt gene and 7S UTR terminator while being compared with the crylAc gene and cry1Ab/Ac gene expression cassettes reported previous. Primer pair cry1Aa-F/crylAa-R was designed and construct-specific detection method of cry1Ab/Aa gene expression cassette was established based on the difference. Eight of eighteen cotton varieties from Jiangsu province were identified to have crylAa gene expression cassette using this methods. The method established was useful for identification Bt gene expression cassette and analysis oftransgenic lineages.关键词
