beta-d-glucopyranosyl abscisate

β-D-Glucopyranosyl abscisate (ABA-GE) is a hydrolyzable conjugate of abscisic acid (ABA), which predominantly accumulates in the vacuole and likely in the endoplasmic reticulum. The deconjugation of β-D-Glucopyranosyl abscisate enables a swift release of free ABA in response to abiotic stress factors like dehydration and salt stress. β-D-Glucopyranosyl abscisate plays a crucial role in maintaining ABA homeostasis.
