在农杆菌中Ti质粒上的若干重要区域共同作用下 ,将经改造的含有目的基因的T -DNA片断导入植物基因组中 ,并得以表达。采用农杆菌介导法 ,山西省农业科学院棉花研究所已将多个外源基因导入棉花中 ,获得转化品种与品系。
Under the action of several important regions on the Ti plasmid in Agrobacterium, the modified T-DNA fragment containing the target gene is introduced into the plant genome and expressed. Using Agrobacterium-mediated method, the Cotton Institute of Shanxi Academy of Agricultural Sciences has introduced a number of foreign genes into cotton to obtain transformed varieties and lines.
