摘要
ABA具有调节植物生长发育和对环境胁迫做出快速反应的重要功能,植物内源ABA水平受到ABA合成、代谢及转运等途径的复杂调控。该文综述了近年来植物ABA从头合成、羟基化代谢、可逆糖基化代谢及ABA转运等领域的最新研究进展,重点讨论ABA合成与代谢基因的表达调控机制,并展望了今后的研究方向。
Abscisic acid(ABA) plays important roles in regulating plant growth and development, and in responding rapidly to various environmental stimuli. The endogenous ABA level in plants is regulated sophisticatedly by the ABA biosynthesis, catabolism, and transportation pathways. This paper reviewed the most recent advancements in ABA de novo biosynthesis, ABA hydroxylation catabolism, reversible glycosylation metabolism, and ABA transportation pathway in plants, with emphasis on the expression regulation mechanism of the ABA biosynthetic and catabolic genes. Prospectives for research directions in the future were also suggested.
