UV Lighting in Horticulture: A Sustainable Tool for Improving Production Quality and Food Safety

Horticulturae, 2021
Ultraviolet (UV) is a component of solar radiation that can be divided into three types defined by waveband: UV-A (315–400 nm), UV-B (280–315 nm), and UV-C (

Ecological Adaptation Mechanisms Underlying Successful Plant Reproduction

Advanced Science, Volume 13, Issue 38, 9 July 2026.
During floral induction, various environmental and endogenous signals converge to regulate the florigen protein, which is transported from leaves to the SAM to initiate flowering. Within the SAM, a complex network of receptor kinases and small peptides orchestrates floral development with high spatiotemporal precision.

Expression of the UVR8 photoreceptor in different tissues reveals tissue-autonomous features of UV-B signalling [PDF]

, 2017
The Arabidopsis UV-B photoreceptor UV RESISTANCE LOCUS 8 (UVR8) orchestrates the expression of hundreds of genes, many of which can be associated with UV-B tolerance.

Effects of Preharvest Calcium Chloride and Postharvest UV‐B Irradiation and Cyanocobalamin Treatments on Storage Quality and Bioactive Properties of Beet Microgreens

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
Preharvest calcium chloride application combined with postharvest UV‐B irradiation effectively enhances photosynthetic pigments, antioxidant capacity, and shelf‐life quality of beet microgreens during storage. ABSTRACT Microgreens are emerging functional foods valued for their unique color, intense flavor, and high levels of bioactive compounds, which ...

UVR8 disrupts stabilisation of PIF5 by COP1 to inhibit plant stem elongation in sunlight

Nature Communications, 2019
UV-B light suppresses the shade avoidance response in plants by reducing the abundance of PIF transcription factors by an undefined mechanism. Here the authors show that UV-B perceived by the UVR8 receptor inhibits the shade avoidance response by ...

Pangenome analysis reveals the genetic mechanism underlying high‐altitude adaptation in Qinghai–Xizang (Tibet) Plateau Rhododendron

Journal of Integrative Plant Biology, Volume 68, Issue 7, Page 2166-2188, July 2026.
Pan‐genome analysis reveals that high‐altitude Rhododendron species resist alpine cold stress by rapidly sensing and engaging the chilling response pathway and genes that directly and indirectly protect the plant from UV radiation. Heritable genomic features such as long terminal repeats contribute to the adaptive diversification of Rhododendron ...

Distinct contributions of cryptochromes and UVR8 to blue light signaling and root development in Arabidopsis

Environmental and Experimental Botany
Plants integrate spectral cues through interconnected photoreceptor networks, yet how blue light receptors interact with UV-B signaling components under mixed light environments remains unresolved.

Reversible Lichtinduzierte Oligomerisierung von Arabidopsis‑Cryptochrom 1 und Antagonismus durch BIC1: Einblicke durch Zeitaufgelöste Native Massenspektrometrie

Angewandte Chemie, Volume 138, Issue 21, 18 May 2026.
Mittels zeitaufgelöster nativer Massenspektrometrie wird der blaulichtabhängige kinetische Mechanismus der Oligomerisierung von Arabidopsis CRY1 aufgedeckt. Die Oligomerisierung verläuft sequenziell von Monomeren über Dimere zu Tetrameren. Während ATP die Assemblierung fördert, inhibiert BIC1 die Tetramerbildung und dissoziiert diese unabhängig von ...

Reversion of the Arabidopsis UV-B photoreceptor UVR8 to the homodimeric ground state

, 2013
Plants require the UV-B photoreceptor UV RESISTANCE LOCUS 8 (UVR8) for acclimation and survival in sunlight. Upon UV-B perception, UVR8 switches instantaneously from a homodimeric to monomeric configuration, which leads to interaction with the key ...
