How do plants fine-tune their responses to light and warmth?

In PNAS, Wang and colleagues identified a direct connection between the receptor kinase FERONIA and phytochrome B (phyB), a major plant light and temperature sensor.

The researchers showed that FERONIA phosphorylates Ser24 and Ser25 in phyB’s N-terminal extension. Phosphorylation at these sites accelerates conversion from the active Pfr state toward the inactive Pr state, reduces photobody persistence, and attenuates phyB signaling.

PhytoAB’s mouse monoclonal anti-phyB antibody (PHY1733) was used at a 1:1,000 dilution for Western blot detection of endogenous phyB in Arabidopsis seedlings.
