| Summary, etc. | Water scarcity and soil carbon dioxide elevation in arid regions are considered the most serious <br/>factors affecting crop growth and productivity. This study aimed to investigate the impacts of <br/>elevated CO2 levels (eCO2 at rates of 700 and 1000 ppm) on agro-physiological attributes to <br/>induce drought tolerance in cucumbers by activating the expression of genes related to <br/>aquaporin and stress response, which improved the yield of cucumber under two levels of <br/>irrigation water conditions [75% and 100% crop evapotranspiration (ETc)]. Therefore, two field <br/>experiments were conducted in a greenhouse with controlled internal climate conditions, at the <br/>Mohamed Naguib sector of the national company for protected agriculture, during the winter <br/>seasons of 2021-2022 and 2022-2023. The treatments included eCO2 in soil under normal and <br/>partial root zoon drying (PRD, 100% ETc Full irrigations, and 75% ETc). All the applied <br/>treatments were organized as a randomized complete block design (RCBD) and each treatment <br/>was replicated six times. Untreated plants were designed as control treatment (CO2 <br/>concentration was 400 ppm). The results of this study showed: that elevating CO2 at 700 and <br/>1000 ppm in soil significantly increased plant growth parameters, photosynthesis <br/>measurements, and phytohormones [indole acetic acid (IAA) and gibberellic acid (GA3)], under <br/>partial root-zone drying (75% ETc) and full irrigation conditions (100% ETc). Under PRD <br/>condition, eCO2 at 700 ppm significantly improved plant height (13.68%), number of shoots <br/>(19.88%), Leaf greenness index (SPAD value, 16.60%), root length (24.88%), fresh weight <br/>(64.77%) and dry weight (61.25%) of cucumber plant, when compared to untreated plants. The <br/>pervious treatment also increased photosynthesis rate, stomatal conductance, and intercellular <br/>CO2 concentration by 50.65%, 15.30% and 12.18%; respectively, compared to the control <br/>treatment. Similar findings were observed in nutrient concentration, carbohydrate content, <br/>Proline, total antioxidants in the leaf, and nutrients. In contrast, eCO2 at 700 ppm in the soil <br/>reduced the values of transpiration rate (6.33%) and Abscisic acid (ABA, 34.03%) content in <br/>cucumber leaves compared to untreated plants under both water levels. Furthermore, the results <br/>revealed that the gene transcript levels of the aquaporin-related genes (CsPIP1-2 and CsTIP4) <br/>significantly increased compared with a well-watered condition. The transcript levels of CsPIP <br/>improved the contribution rate of cell water transportation (intermediated by aquaporin's genes) <br/>and root or leaf hydraulic conductivity. The quantitative real-time PCR expression results <br/>revealed the upregulation of CsAGO1 stress-response genes in plants exposed to 700 ppm CO2. <br/>In conclusion, elevating CO2 at 700 ppm in the soil might be a promising technique to enhance <br/>the growth and productivity of cucumber plants in addition to alleviating the adverse effects of <br/>drought stresses. |
