生物活性

β-D-Glucopyranosyl abscisate (ABA-GE) 是一种可水解的脱落酸 (ABA) 结合物，在液泡和内质网中积累。β-D-Glucopyranosyl abscisate的解聚使自由ABA在非生物胁迫条件下迅速形成，如脱水和盐胁迫。β-D-Glucopyranosyl abscisate 有助于维持ABA稳态。

体外研究

Deconjugation of β-D-Glucopyranosyl abscisate (ABA-GE) by the endoplasmic reticulum and vacuolar β-glucosidases allows the rapid formation of free ABA in response to abiotic stress conditions such as dehydration and salt stress. β-D-Glucopyranosyl abscisate further contributes to the maintenance of ABA homeostasis, as it is the major ABA catabolite exported from the cytosol. Vacuolar transport ofβ-D-Glucopyranosyl abscisate is mediated by ATP-binding cassette and proton-antiport mechanisms in arabidopsis.
