SlGRF1 mediates gibberellin signaling to control cut‐budding in tomato Upon wounding, cytokinin increases to initiate callus formation. Gibberellin enhances this, but later blocks bud formation by suppressing SlGRF1. Wounding-induced protein SlGRF1 triggers buds via NAM...

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...
