摘  要:
为进一步提高油料作物亚麻荠的含油量,克隆拟南芥胚珠组织特异型基因的启动子pINO和拟南芥细胞色素P450 KLUH基因(KLU),以植物表达载体pCAMBIA2301为基础载体,构建组织特异性启动子pINO调控KLU基因的植物表达载体pCAMBIA2301-pINO-KLU,用根癌农杆菌介导的floral dip法转化亚麻荠。结果表明,农杆菌培养至OD600值为0.8时,用等体积渗入培养基(1/2MS、5%蔗糖、200μL/L Silwet L-77)重悬菌体转化亚麻荠,50mg/L卡那霉素检测转基因种子的阳性率为15%,PCR检测初步证明,KLU基因已整合到部分抗性植株的基因组中,转化率为1.8%。

摘  要:
For further improving the oil content of an alternative oil crop species Camelina sativa(L.)Crantz,we cloned the Arabidopsis ovule organ-specific promoter(pINO)and the Arabidopsis cytochrome P450 KLUH gene(KLU).Next,the plant expression vector pCAMBIA2301 was digested and fused KLUwith pINOto construct the plant express vector pCAMBIA 2301-pINO-KLU,which was introduced into Camelina sativa(L.)Crantz with Agrobacterium-mediated floral dip transformation.The results showed that through using the Agrobacterium pellet to transformCamelina sativa(L.)Crantz,which was resuspended by the same volume of infiltration medium(1/2MS,5% sucrose,200μL/L Silwet L-77)when Agrobacteriumculture was cul tured to OD600=0.8,positive rate of screening transgenic seeds by Kan(50mg/L)was 15%.Further PCR analysis confirmed that KLUgene had been incorporated into the genome of parts of resistant plant,and the transformation efficiency was 1.8%.
