AtNCED3及AtAAO3基因启动子功能分析及其驱动CHS基因表达

Analysis of AtNCED3 and AtAAO3 Promoters Function and the Promoter-driven Tobacco(Nicotiana tabacum) CHS Gene Expression

NCED3及AAO3系ABA信号积累的关键基因,其转录调控研究是细胞ABA信号精细调节及植物抗逆分子机制阐明的关键.通过NCED3及AAO3启动子结构与功能的分析,建立了NCED3及AAO3启动子驱动CHS基因表达受干旱诱导致烟草花色变化的体系.

NCED3 and AAO3 are key genes to the ABA signaling accumulation, research of their transcriptional regulation is the premise of the molecular mechanism elucidation in cell ABA signal fine - tune and plant stress resistance. Because of the hmitations of yeast hybrid system in the identification of transcription factors, analysis of AtNCED3 and AtAAO3 promoters function and the promoter - driven CHS gene expression, provide a new system for isolation and identification of transcription factors, as well as a new idea. for flower color genetic modification.
