摘　　要：多效唑是一种赤霉素合成抑制剂,抗多效唑(paclobutrazol-resistance,PRE)基因家族编码的蛋白质可与多效唑发生拮抗作用,这些蛋白质具有螺旋-环-螺旋(basic Helix-Loop-Helix,bHLH)结构,在高等植物中参与转录调控从而在植物发育的许多方面发挥关键作用.PRE基因通过参与各种激素(如赤霉素,油菜素内酯,生长素等)、温度和光响应信号通路来调节植物的生长和发育,对植物生长发育具有重要意义.综述PRE基因在植物中的研究进展,主要包括PRE基因的基本性质、分类、功能以及所参与的植物生理过程等方面,为进一步研究植物PRE类转录因子基因提供理论基础.Paclobutrazolis an inhibitor of gibberellin synthesis,paclobutrazol-resistance(PRE)is a class of genes that encode proteins antagonistic to the paclobutrazol,the proteins contain basic Helix-Loop-Helix(bHLH)structure that participating transcription regulation,in order to plays important roles in various aspects of plants′development.PRE genes regulate plant growth and development by participating in various hormone,temperature and light response signaling pathways,such as gibberellin(GA),brassinolide(BR),auxin(IAA),so that have great significance for the growth and development of plants.The research progresses of PRE transcription factor in plants were summarized,including the basic properties,classification,function of PRE genes and the physiological processes participated in plants,in order to provide a theoretical basis for further studies of PRE.
