Our findings indicated that increased pH mitigated Cu toxicity-induced alterations of HRMs, and Cu toxicity increased low-pH-induced alterations of HRMs. Increased pH-mediated decreases in ABA, jasmonates, gibberellins, and cytokinins, increases in (\u00b1)strigol and 1-aminocyclopropanecarboxylic acid, and efficient maintenance of salicylates and auxins homeostasis in 300 \u03bcM Cu-treated roots (RCu300); as well as efficient maintenance of hormone homeostasis in 300 \u03bcM Cu-treated leaves (LCu300) might contribute to improved leaf and root growth. The upregulation of auxins (IAA), cytokinins, gibberellins, ABA, and salicylates in pH 3.0 + 300 \u03bcM Cu-treated leaves (P3CL) vs. pH 3.0 + 0.5 \u03bcM Cu-treated leaves (P3L) and pH 3.0 + 300 \u03bcM Cu-treated roots (P3CR) vs. pH 3.0 + 0.5 \u03bcM Cu-treated roots (P3R) might be an adaptive response to Cu toxicity, so as to cope with the increased need for reactive oxygen species and Cu detoxification in LCu300 and RCu300. Increased accumulation of stress-related hormones (jasmonates and ABA) in P3CL vs. P3L and P3CR vs. P3R might reduce photosynthesis and accumulation of dry matter, and trigger leaf and root senescence, thereby inhibiting their growth.<\/jats:p>","DOI":"10.3390\/plants12112144","type":"journal-article","created":{"date-parts":[[2023,5,29]],"date-time":"2023-05-29T07:49:23Z","timestamp":1685346563000},"page":"2144","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Roles of Hormones in Elevated pH-Mediated Mitigation of Copper Toxicity in Citrus sinensis Revealed by Targeted Metabolome"],"prefix":"10.3390","volume":"12","author":[{"given":"Jiang","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Resources and Environment, College of Resources and Environment, Fujian Agriculture and Forestry University, Fuzhou 350002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei-Lin","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Resources and Environment, College of Resources and Environment, Fujian Agriculture and Forestry University, Fuzhou 350002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei-Tao","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Resources and Environment, College of Resources and Environment, Fujian Agriculture and Forestry University, Fuzhou 350002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xu-Feng","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Resources and Environment, College of Resources and Environment, Fujian Agriculture and Forestry University, Fuzhou 350002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huan-Huan","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Resources and Environment, College of Resources and Environment, Fujian Agriculture and Forestry University, Fuzhou 350002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin","family":"Ye","sequence":"additional","affiliation":[{"name":"Department of Resources and Environment, College of Resources and Environment, Fujian Agriculture and Forestry University, Fuzhou 350002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1876-4127","authenticated-orcid":false,"given":"Lin-Tong","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Resources and Environment, College of Resources and Environment, Fujian Agriculture and Forestry University, Fuzhou 350002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8425-1306","authenticated-orcid":false,"given":"Li-Song","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Resources and Environment, College of Resources and Environment, Fujian Agriculture and Forestry University, Fuzhou 350002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"127810","DOI":"10.1016\/j.chemosphere.2020.127810","article-title":"Copper bioavailability, uptake, toxicity and tolerance in plants: A comprehensive review","volume":"262","author":"Kumar","year":"2021","journal-title":"Chemosphere"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"110310","DOI":"10.1016\/j.scienta.2021.110310","article-title":"Increased pH-mediated alleviation of copper-toxicity and growth response function in Citrus sinensis seedlings","volume":"288","author":"Cai","year":"2021","journal-title":"Sci.
