To assess adaptive water-use strategies under elevated air temperature, we conducted a three-year whole-season experiment in natural light climate chambers with ambient, +1 \u00b0C, +2 \u00b0C, and +5 \u00b0C warming treatments. Stomatal conductance (gs), transpiration rate (E), net photosynthetic rate (An) and leaf developmental dynamics were continuously measured across growth stages. Above the photosynthetic optimum leaf temperature (Tleaf-opt-An = 30.8 \u00b0C), An declined while gs increased. The increase in gs accelerated beyond a critical threshold (Tleaf-crit = 34.2). This stomatal\u2013photosynthetic decoupling was associated with enhanced transpiration and evaporative cooling. During the reproductive stage, heat stress constrained grain-filling sink capacity and delayed leaf senescence, sustaining higher An, gs and E. Rice exhibits heat-induced shifts in the coordination among carbon assimilation, stomatal behaviour, and water use, while source\u2013sink dynamics under heat-stress further modulated carbon assimilation and water consumption. Incorporating these mechanisms into land surface models is essential for more reliable predictions under global warming scenarios.<\/jats:p>","DOI":"10.1093\/jxb\/erag484","type":"journal-article","created":{"date-parts":[[2026,9,26]],"date-time":"2026-09-26T12:20:32Z","timestamp":1790425232000},"source":"Crossref","is-referenced-by-count":0,"title":["Thermal regulation shapes the coordination of stomatal conductance, transpiration, and photosynthesis in rice"],"prefix":"10.1093","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5603-7409","authenticated-orcid":false,"given":"Yanchao","family":"Zhao","sequence":"first","affiliation":[{"name":"State Key Laboratory of Water Resources Engineering and Management, Wuhan University , Wuhan, 430072, Hubei ,","place":["China"]},{"name":"CREAF, E08193 Bellaterra , Catalonia ,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0714-3728","authenticated-orcid":false,"given":"Jingwei","family":"Wu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Water Resources Engineering and Management, Wuhan University , Wuhan, 430072, Hubei ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1908-4577","authenticated-orcid":false,"given":"Victor","family":"Flo","sequence":"additional","affiliation":[{"name":"CREAF, E08193 Bellaterra , Catalonia ,","place":["Spain"]},{"name":"Universitat Autonoma de Barcelona, E08193, Bellaterra (Cerdanyola del Valles) , Catalonia ,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-9168-5125","authenticated-orcid":false,"given":"Jing","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Water Resources Engineering and Management, Wuhan University , Wuhan, 430072, Hubei ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-9091-7994","authenticated-orcid":false,"given":"Qisen","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Water Resources Engineering and Management, Wuhan University , Wuhan, 430072, Hubei ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0840-1477","authenticated-orcid":false,"given":"Maurizio","family":"Mencuccini","sequence":"additional","affiliation":[{"name":"CREAF, E08193 Bellaterra , Catalonia ,","place":["Spain"]},{"name":"ICREA , Barcelona 08010, Catalonia ,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,9,28]]},"container-title":["Journal of Experimental Botany"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/jxb\/advance-article-pdf\/doi\/10.1093\/jxb\/erag484\/71431589\/erag484.pdf","content-type":"application\/pdf","content-version":"am","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/jxb\/advance-article-pdf\/doi\/10.1093\/jxb\/erag484\/71431589\/erag484.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,28]],"date-time":"2026-09-28T08:54:06Z","timestamp":1790585646000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jxb\/advance-article\/doi\/10.1093\/jxb\/erag484\/8840854"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9,28]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1093\/jxb\/erag484","relation":{},"ISSN":["0022-0957","1460-2431"],"issn-type":[{"value":"0022-0957","type":"print"},{"value":"1460-2431","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,9,28]]},"article-number":"erag484"}}
