Salt tolerance analysis of three-week-old Arabidopsis seedlings grown in soil. (A) Phenotypes of three-week-old MtEF1A1-overexpression (OE) and wild-type (WT) Arabidopsis plants after salt treatment for 21 days. Scale bar = 1 cm. CK, control (0 mM NaCl). (B-D) Levels of H2O2, MDA, and proline in leaves. Plant height (E), rosette leaf weight (F), and stem weight (G) of WT and OE plants treated with 0 or 200 mM NaCl. Values are means ± SD of three biological replicates. Different lowercase letters between different OE lines of one treatment indicate significant differences (p < 0.05)
