摘要:

ABP9参与ABA信号传导及ROS代谢调节,增强植物抵抗非生物逆境胁迫的能力,因此该基因在作物抗逆性改良上有潜在应用价值。为了获得转ABP9基因的玉米植株,向玉米抗逆育种提供新材料,构建了由组成型启动子Ubi驱动抗逆转录因子ABP9基因的植物表达载体,并通过农杆菌介导对玉米自交系齐319进行了遗传转化。经草铵膦抗性筛选和用两对不同的基因特异引物进行PCR扩增检测,证明已将ABP9基因导入玉米齐319基因组中,获得转基因植株。

Abstract:

ABP9 is involved in ABA signal transduction, control of ROS and enhancement of plant tolerance to abiotic stress.  In order to obtain ABP9 transgenic maize plants to provide new material for stress-resistant breeding, a plant vector overexpressing transcription factor ABP9 driven by constitutive promoter Ubi was constructed and transformed into maize inbred Qi319 through Agrobacterium mediated transformation system. Transgenic maize plants were obtained by screening with herbicide glufosinate and PCR amplification of ABP9 with two different pairs of gene-specific primers.

Key words: maize, transgenic, stress resistance, ABP9
