摘要:
将洋葱(Allium cepa)的蔗糖-果糖基转移酶基因SST与甜菜根部特异性启动子MLL重组,以pBI121为起始载体,构建pBI121-MLL-SST,通过农杆菌介导法转化甜菜(Beta vulgaris)品种STFD4,利用聚合酶链式反应(polymerase chain reaction,简称PCR)鉴定转化植株,并用逆转录PCR(reverse transcription PCR,简称RT-PCR)技术检测SST基因的表达。利用干旱胁迫处理进行抗旱性分析,结果表明,与对照(CK)相比,转SST植株叶片萎蔫较迟且程度较轻,其叶片相对含水量和光系统Ⅱ相对量子产率的降低幅度、相对电导率和丙二醛含量的提高幅度均低于对照甜菜植株。以上结果表明,SST基因可明显提高甜菜的抗旱性,为进一步研究该基因在甜菜中的功能奠定了基础。
