RUP2 facilitates UVR8 redimerization via two interfaces

Plant Communications, 2023
The plant UV-B photoreceptor UV RESISTANCE LOCUS 8 (UVR8) exists as a homodimer in its inactive ground state. Upon UV-B exposure, UVR8 monomerizes and interacts with a downstream key regulator, the CONSTITUTIVE PHOTOMORPHOGENIC 1/SUPPRESSOR OF PHYA (COP1/

Transcription factors interact with Arabidopsis UVR8 photoreceptor at distinct sites to COP1 and RUP proteins. [PDF]

Plant J
SUMMARY Many responses of plants to UV‐B radiation are mediated by the UVR8 photoreceptor. UVR8 functions by interacting directly with various proteins. In particular, binding of transcription factors to UVR8 modifies their ability to regulate sets of genes involved in specific responses to UV‐B.

Functional evolution and rewiring of the UVR8–BES1/BIM1 module underpin the refinement of UV-B responses during plant terrestrialization [PDF]

Plant Communications
The UVR8–BES1/BIM1-mediated crosstalk between UV-B and brassinosteroid (BR) signaling orchestrates transcriptional reprogramming and thereby coordinates BR-mediated growth and UV-B responses in flowering plants.

Flavonoid pathway intermediates implicate UVR8 in functions beyond canonical UV-B signaling [PDF]

Nature Communications
Plants integrate light signals to regulate development and produce protective compounds such as flavonoids under excessive light stress. While these metabolites protect against light damage, their roles in modulating photoreceptor responses remain ...

Integration of light quality signals regulates ABA abundance and stomatal movements during seedling establishment. [PDF]

New Phytol
Summary Obtaining sufficient light for photosynthesis and avoiding desiccation are two key challenges faced by seedlings during early establishment. Perception of light quality via specialised photoreceptors signals the availability of sunlight for photosynthesis.

UV‐B Irradiation Does Not Promote Flowering in Arabidopsis Despite Increased FT Expression [PDF]

Plant Direct
Various environmental factors control the plant flowering time. However, the specific effects of ultraviolet (UV)‐B radiation on flowering remain unclear. UV‐B irradiation delays flowering in Arabidopsis during short‐day (SD) photoperiods.

Effects of blue light and UV-B radiation during growth on photochemical yields during exposure to bright sunlight [PDF]

BMC Plant Biology
Background Many plant responses important for photoprotection in high light environments are mediated by photoreceptors for blue and UV radiation. Perception and response to these shortwave regions at relatively low irradiances may function as a means of

The Biosynthesis and Functions of Flavonoids: Recent Advances From Studies Across Land Plant Diversity. [PDF]

J R Soc N Z
Over the last decade there have been significant advances in genome sequencing and model species development for ferns, lycophytes, and the bryophyte lineages—mosses, liverworts, and hornworts. This has facilitated research on the biosynthesis and function of flavonoids in these non‐seed land‐plant lineages.
