Direct receptor competition gates RGL2 proteolysis for seed germination timing in Arabidopsis

Abstract Seed germination is orchestrated by antagonistic gibberellin (GA) and abscisic acid (ABA) signals converging on the master germination repressor RGL2. Here, we unveil a receptor-competition paradigm where ABA receptors (PYLs) stabilize RGL2, both through direct physical interaction and thro...
