Cysteines have a role in conformation of the UVR8 photoreceptor [PDF]
The Plant Journal, 2022 The UVR8 photoreceptor mediates plant responses to UV-B wavelengths. The UVR8 dimer dissociates into monomers following UV-B photoreception, a process accompanied by conformational changes that facilitate interaction of UVR8 with proteins that initiate ...

Role of tryptophans in UVR8 photoreceptor function in arabidopsis [PDF]
The Plant Cell, 2019 Plants are exposed to a variety of environmental cues that can affect their development. Of these, light is the most important as apart from being their energy source, it also serves as an informational cue that will allow them to control a range of ...

The UVR8 UV-B photoreceptor : perception, signaling and response [PDF]
The Arabidopsis Book, 2013 Ultraviolet-B radiation (UV-B) is an intrinsic part of sunlight that is accompanied by significant biological effects. Plants are able to perceive UV-B using the UV-B photoreceptor UVR8 which is linked to a specific molecular signaling pathway and leads ...

A constitutively monomeric UVR8 photoreceptor confers enhanced UV-B photomorphogenesis [PDF]
Proceedings of the National Academy of Sciences, 2021 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 ...

Photoactivated UVR8-COP1 module determines photomorphogenic UV-B signaling output in Arabidopsis. [PDF]
PLoS Genetics, 2014 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

The UV-B photoreceptor UVR8: from structure to physiology [PDF]
The Plant Cell, 2014 Low doses of UV-B light (280 to 315 nm) elicit photomorphogenic responses in plants that modify biochemical composition, photosynthetic competence, morphogenesis, and defense.

Recent advances in UV-B signalling: interaction of proteins with the UVR8 photoreceptor [PDF]
Journal of Experimental BotanyThe UV RESISTANCE LOCUS 8 (UVR8) photoreceptor mediates many plant responses to UV-B and short wavelength UV-A light. UVR8 functions through interactions with other proteins which lead to extensive changes in gene expression. Interactions with particular

Reaction dynamics of the UV-B photosensor UVR8
Photochemical & Photobiological Sciences, 2015 UVR8 is a recently discovered ultraviolet-B (UV-B) photoreceptor protein identified in plants and algae. In the dark state, UVR8 exists as a homodimer, whereas UV-B irradiation induces UVR8 monomerization and initiation of signaling.
