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.

Key words: abscisic acid, ABA biosynthesis, ABA metabolism, ABA transportation
