Here, C\n 4<\/jats:sub>\n maize plants were grown in two [CO\n 2<\/jats:sub>\n ] concentrations (ambient CO\n 2<\/jats:sub>\n (\n a<\/jats:italic>\n [CO\n 2<\/jats:sub>\n ], 400\u2009ppm) and\n d<\/jats:italic>\n [CO\n 2<\/jats:sub>\n ], 800\u2009ppm) and subjected to two salt stress levels (0 and 100\u2009mM NaCl pot\n \u22121<\/jats:sup>\n ) during progressive soil drought. The results indicated that maize leaf ABA concentration (ABA\n leaf<\/jats:sub>\n ) was increased and stomatal conductance (\n g<\/jats:italic>\n s<\/jats:sub>\n ) and leaf hydraulic conductivity (\n K<\/jats:italic>\n leaf<\/jats:sub>\n ) were decreased under salt stress, while\n d<\/jats:italic>\n [CO\n 2<\/jats:sub>\n ] maintained photosynthetic rate (\n A<\/jats:italic>\n n<\/jats:sub>\n ) and leaf water potential (\n \u03a8<\/jats:italic>\n 1<\/jats:sub>\n ), but enhanced leaf WUE. Salt stress advanced the decline in\n A<\/jats:italic>\n n<\/jats:sub>\n , but retarded\n g<\/jats:italic>\n s<\/jats:sub>\n ,\n \u03a8<\/jats:italic>\n 1<\/jats:sub>\n and\n K<\/jats:italic>\n leaf<\/jats:sub>\n , whereas\n d<\/jats:italic>\n [CO\n 2<\/jats:sub>\n ] advanced leaf WUE decline during progressive drought. The\n g<\/jats:italic>\n s<\/jats:sub>\n decline at\n d<\/jats:italic>\n [CO\n 2<\/jats:sub>\n ] was less sensitive to the enhanced ABA\n leaf<\/jats:sub>\n and declined\n \u03a8<\/jats:italic>\n 1<\/jats:sub>\n related to\n a<\/jats:italic>\n [CO\n 2<\/jats:sub>\n ] under salt stress. Hydraulic (\n \u03a8<\/jats:italic>\n 1<\/jats:sub>\n and\n K<\/jats:italic>\n leaf<\/jats:sub>\n ) signals were more crucial than chemical (ABA\n leaf<\/jats:sub>\n ) signals to mediate leaf\n g<\/jats:italic>\n s<\/jats:sub>\n and WUE upon both soil salinity and\n d<\/jats:italic>\n [CO\n 2<\/jats:sub>\n ] in response to progressive drought. Moreover,\n d<\/jats:italic>\n [CO\n 2<\/jats:sub>\n ] mitigated the adverse effects of drought and salt stress on maize plant growth and WUE. The beneficial modulation of\n d<\/jats:italic>\n [CO\n 2<\/jats:sub>\n ] on maize stomata under salt stress in response to progressive soil drought provides some novel insights on improving C\n 4<\/jats:sub>\n crop WUE in a future drier and saltier soil in a CO\n 2<\/jats:sub>\n \u2010enriched scenario.\n <\/jats:p>","DOI":"10.1111\/ppl.70656","type":"journal-article","created":{"date-parts":[[2025,12,1]],"date-time":"2025-12-01T08:18:55Z","timestamp":1764577135000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Doubled\n \n CO\n 2<\/sub>\n <\/scp>\n Mediated Stomatal Behaviour and Water Use Efficiency in Saline Maize Plants Responding to\u00a0Progressive Drought"],"prefix":"10.1111","volume":"177","author":[{"given":"Changtong","family":"Xu","sequence":"first","affiliation":[{"name":"Key Laboratory of Agricultural Soil and Water Engineering in Arid and Semiarid Areas of Ministry of Education Northwest A&F University Yangling Shaanxi China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chunshuo","family":"Liu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Agricultural Soil and Water Engineering in Arid and Semiarid Areas of Ministry of Education Northwest A&F University Yangling Shaanxi China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manyi","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Agricultural Soil and Water Engineering in Arid and Semiarid Areas of Ministry of Education Northwest A&F University Yangling Shaanxi China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wentong","family":"Zhao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Agricultural Soil and Water Engineering in Arid and Semiarid Areas of Ministry of Education Northwest A&F University Yangling Shaanxi China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haoran","family":"Tong","sequence":"additional","affiliation":[{"name":"Key Laboratory of Agricultural Soil and Water Engineering in Arid and Semiarid Areas of Ministry of Education Northwest A&F University Yangling Shaanxi China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingxiang","family":"Hou","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Efficient Utilization of Agricultural Water Resources China Agricultural University Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heng","family":"Wan","sequence":"additional","affiliation":[{"name":"Inner Mongolia Key Laboratory of Soil Quality and Nutrient Resources Inner Mongolia Agricultural University Hohhot China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yiting","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Plant and Environment Sciences, Faculty of Science University of Copenhagen Taastrup Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6672-9708","authenticated-orcid":false,"given":"Zhenhua","family":"Wei","sequence":"additional","affiliation":[{"name":"Key Laboratory of Agricultural Soil and Water Engineering in Arid and Semiarid Areas of Ministry of Education Northwest A&F University Yangling Shaanxi China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,11,30]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.indcrop.2018.12.070"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/agronomy7010018"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2018.09.332"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.plaphy.2020.08.042"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jafc.1c01412"},{"key":"e_1_2_11_7_1","unstructured":"Asch F.2000.\u201cDetermination of Abscisic Acid by Indirect Enzyme Linked Immuno Sorbent Assay (ELISA).\u201d Technical Report.
