|产品介绍||(+)-cis,trans-Abscisic acid is a natural and active isomer of the abscission accelerating plant hormone. The compound is a plant growth regulator which has high-affinity binding sites for abscisic acid on the plasmalemma of Vicia faba guard cells. (+)-cis,trans-Abscisic acid has been involved in several physiological mechanisms including seed dormancy, leaf abscission, stomatal movement, and plant stress responses. Through complex interactions with several intracellular signaling systems, the Abscisic isomer can regulate the expression of hundreds of plant genes.|
