Comparison of the (a) MDA content, (b) SOD, (c) POD, and (d) CAT activities of the overexpression lines (OE1, OE2, and OE3) and controls [wild type (WT) and empty vector (EV)] exposed to cold stress. Data are mean values ± SE of three biological replicates. **and *indicate significant differences compared with the WT at P < 0.01 and P < 0.05 (Student’s t-test), respectively.
