Glucosyltransferase acting on both abscisic acid (ABA) and auxin (IAA). Required for ABA-mediated fruit ripening, seed germination, and negative responses to drought. 2-cis-(+)-abscisate + UDP-alpha-D-glucose = beta-D-glucopyranosyl cis-(+)-abscisate + UDP (indol-3-yl)acetate + UDP-alpha-D-glucose = 1-O-(indol-3-ylacetyl)-beta-D-glucose + UDP Optimum pH is 3.67-8. Optimum temperature is 37 degrees Celsius. Expressed in flowers and fruits, especially in pulp, and, at lower levels, in seeds. Highly expressed during fruit ripening and flower development. In flowers, present at low levels during early developmental stages and later accumulates rapidly to reach a peak at the pre-blooming stage. Highly expressed in the sporogenous cells in the anther, pistil stigma and ovule and in basal vascular bundles. In fruits, accumulates progressively in the pulp with a maximum level at the pink stage. Highly expressed in the seeds, fruit peel and vascular tissues. Induced by abscisic acid (ABA). Increased sensitivity to exogenous abscisic acid (ABA) and increased resistance to drought stress due to smaller stomatal apertures. Acceleration of fruit ripening with abnormally long shape by enhancing ABA levels and promoting the early release of ethylene (IAA) in immature fruit, and associated with altered expression of fruit ripening genes (e.g. ethylene biosynthesis and cell wall catabolism). Up-regulation of the expression of CYP707A2, which encodes an ABA 8'-hydroxylase, thus preventing excessive ABA accumulation. Seeds exhibit delayed germination and root growth. Belongs to the UDP-glycosyltransferase family.
