植物生长素反应因子研究进展

Advances in Plant Auxin Response Factors

生长素反应因子(ARFs)是植物生长和发育的重要调节因子,在生长素早期反应蛋白(Aux/IAAs)的参与下,通过和生长素反应基因启动子区AuxRE元件的TGTCTC序列结合,共同调控这些基因的表达。近年来关于生长素反应因子的分子结构和ARF与Aux/IAA的相互作用及其对植物生长和发育的影响、作用的靶基因以及分子机制受到人们的重视,并在这些方面做了大量的研究。

Auxin response factors （ARFs） are key regulator in plant growth and development. With participa- tion of primary/early auxin response proteins （Aux/IAAs）, ARFs bind specially to TGTCTC-containing auxin response elements （AuxREs） found in promotors of primary/early auxin response genes. In recent years, the molecular structure of auxin response factors, interaction of ARF and Aux/IAA, their function in plant growth and development, target genes for ARF transcription factors and molecular mechanisms involved in ARFs＇ reg- ulation ofgene expression in Arabidopsis and rice were focused on and illuminated by many research Papers.
