植物激素脱落酸AB A 受体得讨论摘要 脱落酸ABA(abscisic acid, ABA)就是一种重要得植物激素,参加高等植物生长发育、抗逆等诸多生理过程。近些年发现得能与ABA结合并发挥受体功能得有FCA(Flowering Control Locus A)、ABAR/CHLH(Mg离子螯合酶H亚基)、GCR2(G蛋白偶联受体)、GTG1/2(GPCR—t ype G p ro t ein 1 / 2 ) 与 PYR/PYL / R C A R ( pyr a b ac t i n resistant / PYR—l i ke / regu l ato r y p o n ent of A B A ) , 其中PYR/PYL/RCAR被普遍认为就是真正得ABA受体蛋白.目前ABA受体得讨论主要集中在拟南芥与水稻等几个模式植物中。本文概述了以上几种ABA受体得讨论进展,重点介绍以PYR/PYL/RCAR为受体在ABA信号传导途径中得作用模式,旨在为ABA受体及其信号转导通路得相关讨论提供参考.关键词 脱落酸;ABA受体;信号转导Research on Abscisic Acid(ABA)Receptor in plantsAbstract Abscisic acid (ABA) is a key plant stress hormone,which involved in many important processes of growth and development in higher plants、 Recent years, FCA(Flowering Control Locus A), ABAR/CHLH(H subunit of the chloroplast Mg2+—chelatase), GCR2( G-protein Coupled Receptor)、GTG1/2(GPCR-type G protein 1/2),PYR/PYL/RCAR(pyrabactin resistant/PYR-like/regulatory ponent of ABA) was found cound bond with ABA and function as ABA Receptor、 PYR/ PYL/ RCAR is considered to be the most widely studied ABA receptor 、 Currently, most research focuses on several model plants such as Arabidopsis and rice、 This paper describes the research progress of several kind of ABA receptor above, highlighting the PYR / PYL / RCAR as ABA receptors in the mode of action of the ABA signal transduction pathway, To research for the ABA receptor ...
