Reversion of the Arabidopsis UV-B photoreceptor UVR8 to the homodimeric ground state.

Proceedings of the National Academy of Sciences of the United States of America - 15 Jan 2013

Heijde Marc, Ulm Roman

Abstract excerpt

Plants require the UV-B photoreceptor UV resistance locus 8 (UVR8) for acclimation and survival in sunlight. Upon UV-B perception, UVR8 switches instantaneously from a homodimeric to monomeric configuration, which leads to interaction with the key signaling protein constitutively photomorphogenic 1 (COP1) and induction of UV-B-protective responses. Here, we show that UVR8 monomerization is reversible in vivo,...
