The UV-B photoreceptor UV RESISTANCE LOCUS 8 (UVR8) plays a central role in perceiving and transducing these signals. In the absence of UV-B, UVR8 exists predominantly as a homodimer in the cytoplasm. Upon UV-B absorption, UVR8 dissociates into active monomers that translocate to the nucleus, where they initiate downstream signaling via interactions with core regulatory components. In this review, we systematically elaborate on the UVR8-mediated UV-B signal transduction cascade and the origin and diversification of UVR8, with a focus on the regulatory effects of UV-B on the nutritional quality, stress resilience, and reproductive traits of horticultural plants. We further propose future directions for the genetic improvement of horticultural crops and the development of light-environment manipulation technologies based on the UVR8 signaling network. This review aims to provide a theoretical reference for enhancing the economic value of horticultural products and advancing green, efficient horticultural production.<\/jats:p>","DOI":"10.1093\/hr\/uhag180","type":"journal-article","created":{"date-parts":[[2026,5,6]],"date-time":"2026-05-06T10:25:26Z","timestamp":1778063126000},"source":"Crossref","is-referenced-by-count":1,"title":["UVR8-mediated
