Photoactivated UVR8-COP1 module determines photomorphogenic UV-B signaling output in Arabidopsis.

PLoS genetics - 1 Mar 2014

Abstract excerpt

In Arabidopsis, ultraviolet (UV)-B-induced photomorphogenesis is initiated by a unique photoreceptor UV resistance locus 8 (UVR8) which utilizes its tryptophan residues as internal chromophore to sense UV-B. As a result of UV-B light perception, the UVR8 homodimer shaped by its arginine residues undergoes a conformational switch of monomerization. Then UVR8 associates with the constitutively photomorphogenic...
