Abstract: Abscisic acid (ABA) is an important plant stress-resistant hormone. The screening and identification of ABA receptors lay an important foundation for elucidating ABA signal transduction pathways in plants. Several kinds of ABA receptors have been found, most of which are questioned, but PYR/PYL/RCAR is generally considered to be the true ABA receptor protein. The research progress of ABA receptors before the discovery of PYR/PYL/RCAR was briefly introduced,and the research progress of PYR/PYL/RCAR protein at home and abroad were detailed introduced.

Key words: abscisic acid receptors, PYR/PYL/RCAR, signal transduction, physiological function
