Research progress of PRE transcription factor genes in plants
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.
