May act as a negative regulator of abscisic acid (ABA)-mediated osmotic stress signaling and function in cross-talk between cold and osmotic signaling. Interacts (via N-terminus) with SCRM/ICE1. Expressed in roots, hypocotyls, vasculature of cotyledons and leaves, hydathodes and guard cells. In reproductive organs, expressed in trichomes, veins of sepals, stamens and stigmata of pistils. By abscisic acid (ABA), salt, osmotic and drought stresses. Reduced apical meristem dominance and length of hypocotyl, and increased cotyledon curling. Mutant plants are hypersensitive to ABA and osmotic stress. Belongs to the ADIPOR family.
