A research study has revealed the central signal sorting hub that plants use
to coordinate biological processes. Dr. Vinod Kumar of the John Innes Centre
(JIC) said that their research has revealed the existence of a central
signal sorting hub, which fine tunes plant growth and immunity in line with
key seasonal cues.

Using Arabidopsis, the JIC research team found two key proteins, DET1 and
COP1, at the center of this signaling hub. The proteins are known for their
role in light signalling and growth control. This study has shown a new role
of these proteins in plant defense. DET1 and COP1 along with the
transcription factor PIF4 control the coordination of growth and immunity in
response to day length and temperature.
