Direct receptor competition gates RGL2 proteolysis for seed germination timing in Arabidopsis - The EMBO Journal 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 w...

Yuan Zheng and coworkers identify receptor competition as a mechanism underlying stabilization of the #Arabidopis master germination repressor RGL2, integrating abscisic acid and #gibberellin signaling during seed germination
