Differential analysis of wild-type (WT) and transgenic plants under cold treatment. A Phenotypic changes of WT and transgenic plants under cold treatment. Nine-leaf-stage plants were placed in a light incubator with a 12-h photoperiod, and cultured at 25 °C for 48 h as a control group (CK). Then, the culture temperature was lowered to 20 °C, 15 °C, 10 °C, 5 °C, 0 °C for 48 h. B Relative electrolyte leakage (REL) changes in WT and transgenic plants under cold treatments. C Peroxidase (POD) changes in WT and transgenic plants under cold treatments. Nine-leaf-stage plants were cultured at each temperature for 48 h. Columns denote the average under each temperature, and the standard errors are marked
