ABA perception recruits an ABA-binding regulatory component [regulatory component of ABA receptor (RCAR)\/PYR1\/PYL] and an associated protein phosphatase 2C (PP2C). Phytohormone binding to the RCAR inactivates the phosphatase activity of the coreceptor, permitting phosphorelay of the ABA signal via downstream protein kinases. The amino acid residues of the ABA-binding pocket are conserved among RCAR members; however, RCAR7 has several changes in these residues, and its function as an ABA receptor has remained elusive. Here we show a bona fide ABA receptor function for RCAR7 and identify structural constraints that contribute to specific pairing of RCAR7 with PP2Cs.<\/jats:p>","DOI":"10.1073\/pnas.1322085111","type":"journal-article","created":{"date-parts":[[2014,4,1]],"date-time":"2014-04-01T22:46:43Z","timestamp":1396392403000},"page":"5741-5746","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":88,"title":["Abscisic
