Signaling by a tyrosine-sulfated peptide balances growth and osmotic stress response in rice.

OsPSY8 peptide signaling regulates the switch between growth and osmotic stress responses in rice, with mutants showing increased stress tolerance.

• Why it matters: Understanding how plants balance growth and stress responses is crucial for improving crop resilience, as the transition mechanisms are not well characterized.
• What they did: Researchers examined OsPSY8 expression and function using mutants and overexpression lines, analyzing root growth, stress tolerance, and transcriptomic changes under osmotic stress.
• The result: Disruption of OsPSY8 enhanced stress tolerance and activated adaptive pathways, indicating OsPSY8's role in suppressing stress responses during growth, which could inform crop stress management strategies.
