Abscisic acid (ABA) is a key plant hormone produced in response to abiotic stress such as drought and salt. It is mainly synthesized in roots and vascular tissues and transported to specific sites to exert physiological functions. Several ABA transporters have been identified; however, the molecular mechanism underlying specific binding and cross-membrane transport of ABA remains unknown.
