The constitutive expression of ThbZIP1 decreases cell death and water loss rate under stress conditions. A: Cell death staining with Evans blue before (Control) and after the treatment of NaCl, mannitol, or ABA. B: Comparison of electrolyte leakage between Col-0 and ThbZIP1 transformed plants. C: Assay of cell death between transgenic and Col-0 plants using propidium iodide (PI) fluorescence staining. D: Transpirational water loss rate analyses in Col-0 and ThbZIP1 transformed plants. All experiments were repeated three times. Data are means ± SD from three independent experiments. * Significant (t test, P < 0.05) difference compared with Col-0 plants.
