摘要: 以含有P5CS的重组质粒pBIP5CS-F129A为模板,通过PCR的方法获得了目的基因P5CS(1905 bp)并将其克隆到pBS-T载体上。利用限制性核酸内切酶BamHⅠ和SalⅠ将P5CS基因从克隆载体上消化下来,定向插入到无GUS基因植物表达载体pCHF3的CaMV35S启动子和NOS终止子之间。通过冻融法将此表达载体导入农杆菌LBA0中,经PCR鉴定表明,P5CS基因植物表达双元载体构建成功。

关键词: 抗旱、耐盐基因, P5CS基因, 克隆, 植物表达载体

Abstract: The gene P5CS (1905 bp) was amplified via PCR using pBI P5CS-F129A plasmid as template and cloned into pBST vector. The Bam HⅠ/ SalⅠfragment from the recombinant plasmid pBST/P5CS was ligated directively between CaMV35S promotor and NOS terminater of the expression vector pCHF3 without GUS gene. The plant expression vector pCHF3/ P5CS was transfered into Agrobacterium tumefaciems strain LBA4404 by freeze-thaw method,and the expression binary plasmid was further identified by PCR. The results showed that pCHF3/P5CS vector was constructed successfully.

Key words: Drought,salt resistance gene, P5CSgene, Plant expression vector
