摘要: 生长素应答因子(auxin response factor,ARF)是转录因子的一个家族,在生长素信号传导途径中起着关键的作用。通过GenBank上登录的序列设计引物,利用RT-PCR技术扩增得到了陆地棉生长素应答因子ARF3的全长序列,并构建到植物表达载体pCAMBIA1301上,借助真空渗透转化技术,在农杆菌GV3101介导下转化模式植物拟南芥,经潮霉素筛选,得到了批量的转基因植株。通过PCR技术,检测到目的基因成功整合到拟南芥基因组中,RT-PCR检测到了目的基因在转基因植株中得到表达。

Abstract: Auxin response factors (ARFs), a family of transcription factors, have been discovered recently. It plays an important roles in auxin signal transduction pathway. We have successfully got the whole sequence of cotton ARF3 through RT-PCR, and transferred it to the plant expression vector,pCAMBIA1301.By Vacuum infiltration technology ,the plant expression vector has been transmitted into Arabidoposis thaliana. We have got planty of transgentic plants. The PCR detection proves the sequnece has successfully recombined with the genome of Arabidoposis thaliana.We also prove its expression by the method of RT-PCR.
