Endogenous ABA level and carotenoids (lutein, β-carotene) content in WT and transgenic A. thaliana plants under normal condition and drought stress. a Endogenous ABA level in WT and transgenic A. thaliana (OE-3, OE-10, OE-13) plants under normal condition and after 15 d of drought treatment. b-c Lutein (b) and β-carotene (c) content in WT and transgenic A. thaliana (OE-3, OE-10, OE-13) plants under normal condition and after 15 d of drought treatment. Bars represent mean standard deviation (SD). Asterisks (*) indicate significant differences between transgenic plants (OE-3, OE-10, OE-13) and the WT plants (* P < 0.05; ** P < 0.01; *** P < 0.001). The letters above the bars indicate significant differences between the plant lines (P < 0.05, according to Tukey’s multiple range test)
