Evaluation of physiological indices responsive to cold stress. (A) Proline content (Pro); (B) electrolyte leakage (EL); (C) malondialdehyde content (MDA); (D) chlorophyll content; (E) peroxidase activity (POD); (F) catalase activity (CAT); (G) superoxide dismutase activity (SOD); (H) O2⁻ content; (I) H₂O₂ content in WT, VL (vector line), and overexpression-MbICE1 under Cold 0 h and Cold 12 h. The value is the average of three repeats, and the standard deviation is represented by the error bar. The asterisk indicates difference among WT, VL, and overexpression-MbICE1 (** p ≤ 0.01). Each index of WT in each treatment was used as the control group.
