RNHL1 phase separation coordinates ethylene and gibberellin signaling to regulate wheat plant height.

Summary
PubMedScientists discovered a protein in wheat that physically clusters together to coordinate two key growth hormones, helping control how tall the plant grows. This finding could lead to better-engineered wheat varieties with optimized plant height for improved crop yields and resilience.

Key Findings
The protein RNHL1 undergoes phase separation (forms liquid-like droplets) to coordinate ethylene and gibberellin hormone signaling pathways simultaneously
RNHL1 acts as a molecular hub regulating plant height in wheat by integrating two distinct hormonal signals at the same physical location
Disruption or manipulation of RNHL1 phase separation alters wheat plant height, demonstrating its causal role in growth regulation

Species Mentioned
Wheat is a group of wild and domesticated grasses of the genus Triticum. As cereals, they are cultivated for their grains, which are staple foods around the world. Well-known wheat species and hybrids include the most widely grown common wheat, spelt, durum, emmer, einkorn, and Khorasan or Kamut....
