| 摘 要： | 应用聚合酶链式反应技术（PCR）扩增水稻OsGL1-2基因反义片段及基因自身的启动子,并分别克隆到pUC19克隆载体上,得到含有OsGL1-2启动子＋OsGL1-2反义片段的中间载体.对重组子进行PCR检测和酶切分析并测序,结果表明,长度分别为417和2 199bp.将OsGL1-2启动子＋OsGL1-2反义片段克隆到植物表达载体pCambia1380多克隆位点,构建了该基因的植物反义表达栽体pCamGL1-2.

| Abstract: | OsGL1-2 antisense fragment and its promoter were amplified by PCR technique and cloned into the same pUC19 clone vector. ＇lherecombinant clones were detected by both PCR technique and restriction enzymes. The OsGL1-2 antisense fragment and promoter were se-quenced. Results showed that the lengths of the both DNA fragments were 417 bp and 2199 bp, respectively. The OsGL1-2 promoter ＋ OsGL1-2 antisense fragment fi＇om intermediate vector pUC19 was cut off and cloned into the multiple cloning sites of the plant expression vector pCam-bia1380, which can be used as antisense expression vector pCamGLl-2 for down-regulation of OsGL1-2 gene. |
