摘　　要：脱落酸(ABA)在种子的发育、休眠、萌发以及植物的营养生长、环境胁迫响应等过程中具有重要作用,植物体具有控制ABA的合成、降解、信号感知及其信号转导的调节机制。目前对高等植物ABA的合成途径及其调节机制的研究已比较深入,合成途径中的所有关键酶基因都已鉴定出,但对ABA分解代谢的研究则相对滞后。概述了ABA的生物合成、分解代谢途径及其调节机制。ABA plays important roles in ninny cellular processes including seed development, dormancy, germination, vegetative growth and environmental stress responses. These diverse functions of ABA involve complex regulatory mechanisrms controling its production, degradation, signal perception, and transduction. The pathway for ABA biosynthesis in higher plants is now understood in great detail through genetic and biochemical studies, and all the major genes for the enzymes in the biosynthesis pathway have been identified. However, much remains to be learned about ABA catabolism pathway and its regulation mechanism. In this review, the pathways of ABA biosynthesis, catabolism and their regulation mechanisms were present.
