Abstract: Abscisic acid is an important phytohormone that has many functions in higher plants, including seed germination, development and dormancy; regulating stomatal movement; and improving stress tolerance. However, two major drawbacks have restricted its application as a plant growth regulator for agrochemical use: It is easily metabolized in plants and this leads to concomitant loss of biological activity and geometry (2Z, 4E) of its 2, 4-pentadienoic acid moiety, which is crucial for its hormonal activities to be readily isomerized to biologically inactive (2E, 4E) isomers by light. Accordingly, synthesis of new abscisic acid analogues with higher activity and better photo-stability is important. This paper reviews research advances in the chemical and biological activities of antimetabolic and photostable analogs of abscisic acid.
