Light is important for plants as an energy source and a developmental signal, but it can also
cause stress to plants and modulates responses to stress. Excess and fluctuating light result …

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 …

Abstract Ultraviolet-B radiation (280–315 nm), perceived by the plant photoreceptor UVR8,
is a key environmental signal that influences plant growth and development and can reduce …

Increased UV-B radiation on the earth's surface due to depletion of stratospheric ozone layer
is one of the changes of current climate-change pattern. The deleterious effects of UV-B …

Low doses of UV-B light (280 to 315 nm) elicit photomorphogenic responses in plants that
modify biochemical composition, photosynthetic competence, morphogenesis, and defense …

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 …

Exposure to ultraviolet B (UV‐B) light regulates numerous aspects of plant metabolism,
morphology and physiology through the differential expression of hundreds of genes …

Plastid genes are transcribed by two types of RNA polymerase in angiosperms: the bacterial
type plastid-encoded RNA polymerase (PEP) and one (RPOTp in monocots) or two (RPOTp …

Abstract Ultraviolet-B (UV-B) light is an intrinsic part of sunlight that reaches the earth's
surface, and affects plant survival and adaptation. How plants respond to UV-B light is …

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 …
