Kind: research · Impact: low

## In brief

- A study published in Cell reports that COP1, a central integrator of light signaling in Arabidopsis, senses temperature.
- COP1 does this through an intrinsically disordered region.
- The authors suggest this mechanism may explain how thermomorphogenesis can be modulated across different climates.

## Why it matters

It identifies a molecular mechanism by which a plant light-signaling regulator responds to temperature, which may help explain how plants adjust their growth to different climates.
