A SRL10-AHP2 signaling module coordinates ROS homeostasis and ion balance for salt stress adaptation in rice.

OsSRL10 and AHP2 form a cooperative signaling module that enhances salt stress tolerance in rice by regulating ROS and ion balance, with OsSRL10 overexpression increasing seedling resilience.

• Why it matters: Soil salinity poses a major threat to crop productivity, and understanding the molecular mechanisms of salt tolerance is essential for developing resilient rice varieties to ensure food security.
• What they did: Researchers investigated the OsSRL10-AHP2 interaction through genetic and molecular analyses, demonstrating that OsSRL10 overexpression improves salt tolerance by promoting ROS scavenging and reducing Na+ accumulation, and that these proteins function as a complex.
• The result: This work identifies the SRL10-AHP2 module as a critical regulatory node in rice salt stress adaptation, providing a valuable target for breeding salt-tolerant rice cultivars and advancing stress resilience research.
