摘要
将烟草中经修饰的Ⅰ类几了质酶和β-1,3-葡聚糖酶cDNA分别加上CaMV35S启动子和NOS终止子,依次插入到同一植物表达载体pBin19上,获得植物双价表达载体pCG-Ⅱ。然后载体pCG-Ⅱ以土壤农杆菌LBA4404介导转化番茄,再生植株的点杂交及PCR扩增证明两种cDNA已随T-DNA同时导入番茄植株中。
The modified tobacco Ⅰ-Chitinase (Chi) and b-1, 3 -Glucanase (Glu) cDNAwith CaMV 35 S promotor and NOS terminator were cloned into pBin19, and a plantbivalent expression vector pCG-Ⅱ was obtained. The pCG-Ⅱ was then transformed intotomato through mediation of Agrobacterium tunefaciens LBA4404. The dot-blot hybridization and PCR amplification analysis demonstrated that the Chi and Glu cDNA were integrated into tomato genomes.
