摘要
利用RT-PCR技术从紫花苜蓿中克隆出过氧化物酶基因,命名为MsPOD,并通过DNA重组技术将其连接到载体pBI121上,成功构建植物表达载体pBI-MsPOD;将表达载体转化到感受态农杆菌株GV3101中,利用花序浸泡法获得具有卡纳抗性的转基因拟南芥植株。对其中3个再生植株进行PCR检测表明,目的基因已经成功整合到拟南芥基因组中,通过RT-PCR和GUS染色检测分析,初步证明目的基因在拟南芥中成功表达。
A peroxidase gene was cloned from alfalfa, which was named as MsPOD. By DNA recombi- nation technology, MsPOD gene was inserted into plasmid pBIl21, and a plant expressing vector pBI-POD was constructed. Transgenic Arabidopsis thaliana plants were obtained by floral dip method with Agrobacterium tumefaciens GV3101 harboring pBI-POD plasmid and seeds of transgeinc Arabidopsis thaliana were selected on MS plates containing 50mg/L Kanamycin. PCR analysis of 3 kanamycin resistant plants showed that the target gene was integrated into the genomes of the Arabidopsis thaliana. RT-PCR and GUS staining analysis showed that MsPOD gene expressed in Arabidopsis thaliana.
