3种不同启动子构建ACC脱氨酶基因植物表达载体
Construction of Plant Expression Vectors of ACC Deaminase Gene Using Three Promoters
【摘要】 从阴沟肠杆菌(Enterobacter cloacae)UW4菌株克隆出ACC脱氨酶(1-aminocyclopropane-1-carboxylicacid deaminase)基因连接至pGEM-Tvector上,并采用3种不同启动子(组成型表达启动子CaMV35S、花特异表达启动子CHSA及衰老特异表达启动子SAG12)分别构建ACC脱氨酶基因的植物表达载体,经PCR及酶切鉴定均已构建成功,为后期选择不同的花卉等植物材料遗传转化研究打下基础。
【Abstract】 ACC deaminase gene was cloned from Enterobacter cloacae UW4 strain and ligated into pGEM-T vector.Three different promoters(constitutive expression promoter CaMV35S,flower specific expression promoter CHSA and senescence specific expression promoter SAG12) were respectively utilized to successfully construct three plant expression vectors of ACC deaminase gene after PCR and restriction endonucleases detection,which laid the foundation for the future part of selecting proper flower plants and carrying out its genetic transformation.
【Key words】 ACC deaminase gene; flower specific expression promoter CHSA; senescence specific expression promoter SAG12; plant expression vector construction;
