Q9SE50

abscisic acid is a phytohormone critical for plant growth. Dehydration rapidly induces polymerization of the beta-D-glucopyranosyl abscisate hydrolyzing enzyme AtBG1, resulting in a 4fold increase in enzymatic activity. Diurnal increases in abscisate levels are attributable to polymerization-mediated AtBG1 activation. Activation of inactive abscisate pools by polymerized AtBG1 is a mechanism by which plants rapidly adjust abscisate levels and respond to changing environmental cues. Assembly of AtBG1 into higher molecular weight forms upon dehydration stress occurs at a mild condition such as exposure to 30% relative humidity for 30 min, indicating that the response is very sensitive to dehydration stress

Q9SE50

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

Arabidopsis thaliana

Q9SE50

the stress hormone abscisic acid that enables plants to survive recurring stresses such as drought, cold, and high salt in soils. Abscisate concentrations can be rapidly increased in response to these osmotic stresses. The cleavage of glucose-conjugated abscisate by an abscisate-specific beta-glucosidase, AtBG1, is a way to produce bioactive abscisate in response to dehydration stress and also day/night conditions
