Relative expression of stress-related genes in WT and SikCOR413PM1-overexpressing cotton lines under cold and drought stress. Expression levels of (A) GhDREB1A; (B) GhDREB1B; (C) GhDREB1C; (D) GhRD22; (E) GhERF2; (F) GhNAC3, data shown are means ± SD of three replicates * and ** indicate significant differences relative to WT cotton plants at P < 0.05 and P < 0.01. The expression leve at 0h (control time point) was defined as 1.0
