Popis:	Deciding whether to grow or to divert energy to stress responses is a major physiological trade-off for plants surviving in fluctuating environments. We show that three leucine-rich repeat receptor kinases (LRR-RKs) act as direct ligand-perceiving receptors for PLANT PEPTIDE CONTAINING SULFATED TYROSINE (PSY)-family peptides and mediate switching between two opposing pathways. By contrast to known LRR-RKs, which activate signaling upon ligand binding, PSY receptors (PSYRs) activate the expression of various genes encoding stress response transcription factors upon depletion of the ligands. Loss of PSYRs results in defects in plant tolerance to both biotic and abiotic stresses. This ligand-deprivation–dependent activation system potentially enables plants to exert tuned regulation of stress responses in the tissues proximal to metabolically dysfunctional damaged sites where ligand production is impaired.
