Key Points

Detection of the PrPfr state suggests a role for allostery in phytochromes during dark reversion.
The study highlights findings related to thermal reversion in the context of photosensor proteins.
Allostery at the dimer level could impact how phytochromes function and respond to light.
This research opens avenues for understanding protein interactions in plant signaling mechanisms.

Implication

Observation reveals inter-dimer allostery in the PrPfr state of phytochrome, indicating thermal reversion effects.

Abstract

Phytochromes are photosensor proteins which detect light in plants, fungi, and bacteria. They photoswitch between red light absorbing (Pr) and far-red light absorbing (Pfr) states, however, thermal reversion in the...
