Different plant expression vectors had been respectively transferred into upland cotton cultivars Jinman12, Jinmian7, Xinluzao1 and Jihe321 via Agrobacterium tumfaciens transformation. These vectors carried cryIAc3 gene, which encodes Bacillus thuringiensis δ-endotoxin, under the control of chimeric OM promoter, CaMV 35S promoter, and cotton leaf curl virus RP promoter respectively; snowdrop lectin gene (Galanthus nivals agglutinin, gna) trans-regulated by rolC promoter controlled TGAla factor; and multivalent expression construct of both cryIAc3-cpti fusion gene and gna gene. A large number of transgenic plants and their progenies had been obtained.

为了提高外源基因的表达量,延缓害虫产生耐受性,本文通过将携带有分别在高效复合OM启动子,CaMV35S启动子及棉花曲叶病毒RP启动子控制下的苏云金杆菌杀虫毒蛋白基因cryIAc3;反式调节因子增强韧皮部表达的雪花莲外源凝集素(Galanthus nivals agglutinin,GNA)基因;以及同时含有cryIAc3、豇豆胰蛋白酶抑制剂基因和gna三价抗虫基因的植物表达载体,以根农杆菌介导法分别将这些表达载体导入了陆地棉新陆早1号、晋棉7号、晋棉12号和冀合321等我国西北棉花主要栽培品种,经体细胞胚再生获得了大批转基因再生植株。

The open reading frame of Spinacia oleracea Betaine Aldehyde Dehydrogenase was retrieved from Spinacia oleracea and inserted into the Agrobacterium tumefaciens binary vector pBin438, which was driven by CaMV35S promoter, and produced the new binary vector pBSB. A. tumefaciens LBA4404 carrying this plasmid was used in genetic transformation of plants. Forty-five primary transgenic plants were detected by PCR and verified by the Southern blotting from 65 regenerated plants, of which 27 transgenic plants had only one copy of T-DNA.

摘 要:分离出菠菜甜菜碱醛脱氢酶基因构建成由CaMV35S驱动的双元植物表达载体pBSB,农杆菌菌株LBA4404携带该载体转化棉花,获得转基因棉花植株。65株转基因植株经过PCR筛选、Southern blotting分析证明有45株为成功的转化株,外源基因已经被整合到棉花的染色体组中,并以单拷贝插入居多。
