摘要:
为了研究烟草中重金属镉的代谢转运基因,以马铃薯的植物螯合肽合成酶phytochelatin synthases 1(PCS1)基因的全长cDNA序列(GenBank登录号:AJ548472.1)为信息探针,通过电子克隆的方法从烟草栽培品种中克隆到1个植物螯合肽合成酶基因(NtPCS1),并对其进行了序列分析。序列分析结果:NtPCS1包含完整的开放读码框,编码531个氨基酸,含有2个保守域Phytochelatin_C和Phytochelatin;通过同源比对和进化分析发现,NtPCS1氨基酸序列与番茄PCS1的序列一致性达到85%,与已报道的树烟草NgPCS相比,在N端多出30个氨基酸。以上结果表明NtPCS1是栽培烟草中新发现的金属镉代谢转运基因。
