Revisiting chromatin binding of the Arabidopsis UV-B photoreceptor UVR8 [PDF]

BMC Plant Biology, 2016
Plants perceive UV-B through the UV RESISTANCE LOCUS 8 (UVR8) photoreceptor and UVR8 activation leads to changes in gene expression such as those associated with UV-B acclimation and stress tolerance.

A comprehensive phylogeny reveals functional conservation of the UV-B photoreceptor UVR8 from green algae to higher plants [PDF]

Frontiers in Plant Science, 2016
UV-B is present in sunlight (280- 315 nm) and has diverse effects on living organisms. Low fluence rate of exposure induces a specific photomorphogenic response regulated by the UV-B response locus 8 UVR8 receptor. UVR8 was first described in Arabidopsis

Physiological and multi-omics insights into ultraviolet B-induced stress adaptation in Fritillaria cirrhosa native to the Qinghai-Tibet Plateau [PDF]

Journal of Advanced Research
Introduction: Fritillaria cirrhosa (Liliaceae), an endangered medicinal plant of the Qinghai-Tibet Plateau, exhibits strong adaptability to ultraviolet B (UV-B) radiation during the transition from wild to artificial habitats.

Effects of Continuous Low-Level UV-B, Alone or in Combination with Blue Light, on Photosynthetic and Antioxidant Responses of Morphologically Distinct Red-Leaf Lettuce Cultivars [PDF]

Plants
The physiological, biochemical, and morphometric responses of two lettuce cultivars (Lactuca sativa L.), Gypsy and Pomegranate Lace, which differ in terms of leaf morphology and anthocyanin pigmentation, were examined under moderate light (290 µmol m−2 s−

Photoinduced transformation of UVR8 monitored by vibrational and fluorescence spectroscopy

Photochemical & Photobiological Sciences, 2015
Tryptophan residues at the dimer interface of the plant photoreceptor UVR8 promote monomerisation after UV-B absorption via a so far unknown mechanism.

Interaction of the Arabidopsis UV-B-specific signaling component UVR8 with chromatin [PDF]

Molecular Plant, 2008
Arabidopsis UV RESISTANCE LOCUS8 (UVR8) is a UV-B-specific signaling component that regulates expression of a range of genes concerned with UV protection. Here, we investigate the interaction of UVR8 with chromatin.

Structure and function of the UV-B photoreceptor UVR8

Current Opinion in Structural Biology, 2014
UVR8 is a UV-B photoreceptor that employs specific tryptophans in its primary sequence as chromophores in photoreception. UV-B absorption causes dissociation of the dimeric photoreceptor by neutralizing interactions between monomers.

A FRET method for investigating dimer/monomer status and conformation of the UVR8 photoreceptor [PDF]

Photochemical & Photobiological Sciences, 2019
The photoreceptor UVR8 has a pivotal role in mediating plant responses to UV-B wavelengths. Dimeric UVR8 dissociates into monomers following UV-B photoreception, and there is evidence that this process is accompanied by conformational changes that may ...

A leap in quantum efficiency through light harvesting in photoreceptor UVR8 [PDF]

Nature Communications, 2020
Photoreceptor UVR8 in plants senses environmental UV levels through 26 structural tryptophan residues, but the role of 18 of them was unknown. The authors show, by experiments and computations, how these form a light-harvesting network that funnels the ...

Beyond Arabidopsis: Differential UV-B Response Mediated by UVR8 in Diverse Species

Frontiers in Plant Science, 2019
Ultraviolet-B radiation (UV-B, 280–315 nm) is an important environmental signal that regulates growth and development in plants. Two dose-dependent UV-B response pathways were described in plants: a specific one, mediated by UVR8 (the specific UV-B ...
