Quinabactin(CAT: I040703) is a synthetic small molecule that functions as an abscisic acid (ABA) agonist, mimicking the plant hormone’s activity to regulate stress responses. It selectively activates ABA signaling pathways by binding to PYR/PYL/RCAR ABA receptors, leading to the inhibition of protein phosphatase 2Cs (PP2Cs) and activation of downstream stress-response genes. Quinabactin is widely used in plant biology research to study drought tolerance, seed germination, and stomatal closure. Its ability to induce ABA-like physiological effects makes it a valuable tool for exploring plant stress adaptation mechanisms and developing drought-resistant crops. For research use in plant physiology and agricultural biotechnology.
