CmNAC1-EE lines have enhanced drought stress tolerance. Four-week-old seedlings of WT and EE plants were grown in substrate for treatment. (A) Phenotypes of WT and EE plants during drought stress. (B) Quantitative analysis of survival rate after drought stress. (C) Fully expanded leaves of Arabidopsis plants (5 weeks old) were excised and exposed to dehydration stress for 3 h on dry filter paper at room temperature. Pictures were taken at 0 and 3 h after treatment. (D) Water loss assay from detached leaves of 5-week-old seedlings. (E) CmNAC1 expression levels in transgenic Arabidopsis EE19, EE26 lines and WT plants. (F) Key ABA biosynthesis gene AtNCED3 expression levels in transgenic Arabidopsis EE19, EE26 lines and WT plants. (G) Concentration of ABA in transgenic Arabidopsis EE19, EE26 lines and WT plants. Three independent experiments were performed. Asterisks indicate statistically significant differences compared with WT plants (∗∗P < 0.01).
