Biotechnology for inducing the overproduction of phytohormones such as gibberellins (GAs) is a powerful tool for improving tree yield and wood properties. Augumentation of GAs in trees in temperate and boreal regions, however, prevents the induction of vegetative dormancy, which results in reduced yield and tree loss over time. Hybrid Populus trees (Populus tremula \u00d7 P. tremuloides; Ptt) use an internal circadian clock to synchronise their daily metabolism and seasonal growth with predictable light and temperature changes in their local environment. This study focused on modulating GA production in Populus to demonstrate the importance of seasonal growth adaptation. Levels of bioactive GAs were modulated in transgenic trees using the endogenous D-TYPE CYCLIN 3;1 promoter (pPttCYCD3), which is regulated by the circadian clock component LATE ELONGATED HYPOCOTYL 2 (PttLHY2). This modulation resulted in both high yield and seasonal growth adaptation. Such work paves the way for the precision breeding of trees with increased yield that are adapted to local climate conditions.<\/jats:p>","DOI":"10.1093\/jxb\/erag483","type":"journal-article","created":{"date-parts":[[2026,9,25]],"date-time":"2026-09-25T07:55:11Z","timestamp":1790322911000},"source":"Crossref","is-referenced-by-count":0,"title":["Biotechnological adaptation of high-yielding, gibberellin-overproducing\n                    <i>Populus<\/i>\n                    trees to seasonal growth patterns"],"prefix":"10.1093","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3259-8671","authenticated-orcid":false,"given":"Manuela","family":"Jurca","sequence":"first","affiliation":[{"name":"Department of Plant Physiology, Ume\u00e5 Plant Science Centre, Ume\u00e5 University , SE-901 87 Ume\u00e5 ,","place":["Sweden"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4448-5858","authenticated-orcid":false,"given":"Johan","family":"Sj\u00f6lander","sequence":"additional","affiliation":[{"name":"Department of Plant Physiology, Ume\u00e5 Plant Science Centre, Ume\u00e5 University , SE-901 87 Ume\u00e5 ,","place":["Sweden"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1136-2480","authenticated-orcid":false,"given":"Bertold","family":"Mari\u00ebn","sequence":"additional","affiliation":[{"name":"Department of Plant Physiology, Ume\u00e5 Plant Science Centre, Ume\u00e5 University , SE-901 87 Ume\u00e5 ,","place":["Sweden"]},{"name":"Department of Mathematics and Mathematical Statistics, IceLab, Ume\u00e5 University , SE-901 87 Ume\u00e5 ,","place":["Sweden"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7831-7946","authenticated-orcid":false,"given":"Rajesh Kumar","family":"Singh","sequence":"additional","affiliation":[{"name":"Department of Plant Physiology, Ume\u00e5 Plant Science Centre, Ume\u00e5 University , SE-901 87 Ume\u00e5 ,","place":["Sweden"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6535-9282","authenticated-orcid":false,"given":"Alexander","family":"Vergara","sequence":"additional","affiliation":[{"name":"Instituto de Ciencias de la Ingenier\u00eda, Universidad de O'Higgins , Avenida Libertador Bernardo O'Higgins 611, 2820000 Rancagua, O'Higgins ,","place":["Chile"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5673-620X","authenticated-orcid":false,"given":"Jun","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Mathematics and Mathematical Statistics, IceLab, Ume\u00e5 University , SE-901 87 Ume\u00e5 ,","place":["Sweden"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4258-3190","authenticated-orcid":false,"given":"Thomas","family":"Moritz","sequence":"additional","affiliation":[{"name":"Department of Forest Genetics and Plant Physiology, Ume\u00e5 Plant Science Centre, Ume\u00e5 University , SE-901 83 Ume\u00e5 ,","place":["Sweden"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2038-4892","authenticated-orcid":false,"given":"Maria E","family":"Eriksson","sequence":"additional","affiliation":[{"name":"Department of Plant Physiology, Ume\u00e5 Plant Science Centre, Ume\u00e5 University , SE-901 87 Ume\u00e5 ,","place":["Sweden"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,9,25]]},"container-title":["Journal of Experimental Botany"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/jxb\/advance-article-pdf\/doi\/10.1093\/jxb\/erag483\/71393262\/erag483.pdf","content-type":"application\/pdf","content-version":"am","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/jxb\/advance-article-pdf\/doi\/10.1093\/jxb\/erag483\/71393262\/erag483.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,25]],"date-time":"2026-09-25T07:55:11Z","timestamp":1790322911000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jxb\/advance-article\/doi\/10.1093\/jxb\/erag483\/8835442"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9,25]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1093\/jxb\/erag483","relation":{},"ISSN":["0022-0957","1460-2431"],"issn-type":[{"value":"0022-0957","type":"print"},{"value":"1460-2431","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,9,25]]},"article-number":"erag483"}}
