The hormone abscisic acid (ABA) regulates a variety of developmental and physiological processes in higher plants. Liu et al. (see the Perspective by Grill and Christmann) have now identified a membrane-bound protein that functions as an ABA receptor. The protein, GCR2, has features of a G protein-coupled receptor, which has thousands of variants in animal cells but very few known variants in plant cells.
