beta-D-glucopyranosyl abscisate + H2O Arabidopsis thaliana librated free abscisate may induce growth inhibition in Arabidopsis hypocotyls. Exogenously applied beta-D-glucopyranosyl abscisate may be absorbed by roots and hydrolyzed by beta-D-glucosidase, with the subsequent release of abscisate, which would potentially inhibit the growth of Arabidopsis hypocotyls beta-D-glucopyranose + abscisate

Expression

Organism Comment Expression
Arabidopsis thaliana at the concentration of 100 mM beta-D-glucopyranosyl abscisate, the activity is 1.7fold greater than in controls, which suggests that beta-D-glucopyranosyl abscisate might cause enzyme induction up
