Plant photoreceptor UV RESISTANCE LOCUS 8 (UVR8) homodimers perceive UV-B and dissociate into active monomers to initiate signaling, yet how UVR8 dimer stability and monomer activity are post-translationally regulated remains unclear. We identify UV-B-enhanced phosphorylation at threonine 356 of UVR8, which promotes UV-B-induced UVR8 dimer dissociation and delays redimerization, shifting dimer\/monomer equilibrium towards active monomer in Arabidopsis. Importantly, the same regulatory mechanism is conserved in tomato, demonstrating that phosphorylation at this site represents a broadly applicable molecular switch across species. Moreover, this modification enhances the binding of UVR8 to CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1), prolongs UVR8 nuclear residence, and amplifies UV-B signaling outputs. Together, these findings uncover phosphorylation at T356 as an evolutionarily conserved molecular switch that fine-tunes photoreceptor conformational change and signaling, highlighting phosphorylation as a critical posttranslational control of light perception in plants.<\/jats:p>","DOI":"10.1093\/plcell\/koag285","type":"journal-article","created":{"date-parts":[[2026,9,17]],"date-time":"2026-09-17T19:14:29Z","timestamp":1789672469000},"source":"Crossref","is-referenced-by-count":0,"title":["Phosphorylation of the plant photoreceptor UVR8 regulates its dimer\/monomer status and enhances UV-B signaling across species"],"prefix":"10.1093","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8046-4654","authenticated-orcid":false,"given":"Boqin","family":"Tong","sequence":"first","affiliation":[{"name":"School of Agriculture and Biology, Shanghai Jiao Tong University , 800 Dongchuan Road, Minhang District, Shanghai 200240 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-6490-1551","authenticated-orcid":false,"given":"MeLongying","family":"Wangzha","sequence":"additional","affiliation":[{"name":"School of Agriculture and Biology, Shanghai Jiao Tong University , 800 Dongchuan Road, Minhang District, Shanghai 200240 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Agriculture and Biology, Shanghai Jiao Tong University , 800 Dongchuan Road, Minhang District, Shanghai 200240 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-8316-9494","authenticated-orcid":false,"given":"Baoguo","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Agriculture and Biology, Shanghai Jiao Tong University , 800 Dongchuan Road, Minhang District, Shanghai 200240 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2431-607X","authenticated-orcid":false,"given":"Chunli","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Agriculture and Biology, Shanghai Jiao Tong University , 800 Dongchuan Road, Minhang District, Shanghai 200240 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2055-3430","authenticated-orcid":false,"given":"Andr\u00e1s","family":"Viczi\u00e1n","sequence":"additional","affiliation":[{"name":"Laboratory of Photo and Chronobiology, Institute of Plant Biology, Biological Research Centre, Hungarian Research Network (HUN-REN) , Temesv\u00e1ri krt. 62, Szeged H-6726 ,","place":["Hungary"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0467-9287","authenticated-orcid":false,"given":"Assaf","family":"Mosquna","sequence":"additional","affiliation":[{"name":"The Robert H.
