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p I NO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(1/2 MS、5%蔗糖、200μL/L Silwet L 77)重悬菌体转化亚麻荠,50 mg/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%。
為進一步提高油料作物亞痳薺的含油量,剋隆擬南芥胚珠組織特異型基因的啟動子p I NO和擬南芥細胞色素P450 KLUH基因(KLU),以植物錶達載體pCAMBIA2301為基礎載體,構建組織特異性啟動子pINO調控 KLU基因的植物錶達載體pCAMBIA2301 pINO KLU ,用根癌農桿菌介導的floral dip法轉化亞痳薺。結果錶明,農桿菌培養至OD600值為0.8時,用等體積滲入培養基(1/2 MS、5%蔗糖、200μL/L Silwet L 77)重懸菌體轉化亞痳薺,50 mg/L卡那黴素檢測轉基因種子的暘性率為15%,PCR檢測初步證明,KLU基因已整閤到部分抗性植株的基因組中,轉化率為1.8%。

For further improving the oil content of an alternative oil crop species Camelina sativ a (L .) Crantz ,we cloned the Arabidopsis ovule organ-specific promoter (pINO) and the Arabi-dopsis cytochrome P450 KLUH gene (KLU) .Next ,the plant expression vector pCAMBIA2301 was digested and fused KLU with pINO to construct the plant express vector pCAMBIA 2301-pI-NO-KLU ,which was introduced into Camelinasativa (L .) Crantz with Agrobacterium-mediated floral dip transformation .The results showed that through using the Agrobacterium pellet to transform Camelina sativa (L .) Crantz ,which was resuspended by the same volume of infiltra-tion medium (1/2MS ,5% sucrose ,200 μL/L Silwet L-77) when Agrobacterium culture was cul tured to OD600 =0 .8 ,positive rate of screening transgenic seeds by Kan (50 mg/L) was 15% .Fur-ther PCR analysis confirmed that KLU gene had been incorporated into the genome of parts of re-sistant plant ,and the transformation efficiency was 1 .8% .
