Identification of new abscisic acid receptor agonists using a wheat cell-free based drug screening system

Abscisic acid (ABA) is the main phytohormone involved in abiotic stress response and its adaptation, and is a candidate agrichemical. Consequently, several agonists of ABA have been developed using the yeast two-hybrid system. Here, we describe a novel cell-free-based drug screening approach for the development and validation of ABA receptor agonists. Biochemical validation of this approach between 14 ABA receptors (PYR/PYL/RCARs) and 7 type...
