A thermoregulatory module for timekeeping in Arabidopsis.
PRR9 acts as a key thermoregulatory hub in Arabidopsis, enabling temperature adaptation by promoting liquid-liquid phase separation and modulating circadian gene expression at high temperatures.
- Why it matters: Understanding how plants sense and respond to temperature changes is crucial for improving crop resilience amid climate warming, yet the underlying mechanisms remain largely unknown.
- What they did: The study investigated PRR9’s role in temperature response using molecular and cellular approaches, revealing its accumulation, phase separation, and interaction with other factors under high-temperature conditions.
- The result: Findings demonstrate that PRR9 mediates temperature sensing and circadian regulation, providing insights for engineering crops with enhanced thermo-resilience in warming environments.
