Ultraviolet-B (UV-B) radiation is an intrinsic fraction of sunlight that plants perceive through
the UVR8 photoreceptor. UVR8 is a homodimer in its ground state that monomerizes upon …

Highlights•The COP1/SPA E3 ubiquitin ligase is a repressor of photomorphogenesis.•The
COP1/SPA complex targets photomorphogenesis-promoting factors for proteolysis.•Active …

Phosphorylation modification is required for the modulation of phytochrome B (phyB)
thermal reversion, but the kinase (s) that phosphorylate (s) phyB and the biological …

Summary UV-B light (UV-B radiation) is known to inhibit plant growth, but the mechanism is
not well understood. UVR8 (UV RESISTANCE LOCUS 8) is a UV-B light photoreceptor that …

UV-B light is a potential stress factor in plants, but how plants coordinate growth and UV-B
stress responses is not well understood. Here, we report that brassinosteroid (BR) signaling …

Abstract UV RESISTANCE LOCUS 8 (UVR8) is an ultraviolet-B (UVB) radiation
photoreceptor that mediates light responses in plants. How plant UVR8 acts in response to …

Abstract The UV‐B photoreceptor UVR8 mediates multiple UV‐B responses in plants, but
the function of UVR8 in regulating root development has not previously been investigated …

Highlights•The homodimeric UV-B photoreceptor UVR8 monomerizes in response to UV-B
reception.•Monomeric UVR8 interacts with the E3 ubiquitin ligase COP1 via two distinct …

Abstract Ultraviolet-B (UV-B) radiation from the past few decades has been widely studied
due to the substantial depletion of the stratospheric ozone (O 3) layer, causing …

Light regulates the subcellular localization of plant photoreceptors, a key step in light
signaling. Ultraviolet‐B radiation (UV‐B) induces the plant photoreceptor UV RESISTANCE …
