A constitutively monomeric UVR8 photoreceptor confers enhanced UV-B photomorphogenesis.

Proceedings of the National Academy of Sciences of the United States of America - 9 Feb 2021

Abstract excerpt

The plant ultraviolet-B (UV-B) photoreceptor UVR8 plays an important role in UV-B acclimation and survival. UV-B absorption by homodimeric UVR8 induces its monomerization and interaction with the E3 ubiquitin ligase COP1, leading ultimately to gene expression changes. UVR8 is inactivated through redimerization, facilitated by RUP1 and RUP2. Here, we describe a semidominant, hyperactive allele, namely uvr8-17D,...
