Tomato PYR/PYL/RCAR abscisic acid receptors show high expression in root, differential sensitivity to the abscisic acid agonist quinabactin, and the capability to enhance plant drought resistance

Chemical and transgenic approaches can activate ABA signalling via crop PYR/PYL ABA receptors; quinabactin can selectively activate tomato ABA receptors, and overexpression of monomeric-type receptors confers enhanced plant drought resistance.
