Physiological analysis of WT and SikCOR413PM1-overexpressing cotton plants after cold and drought stress treatments. (A) Malondialdehyde (MDA) content; (B) Relative electrolyte leakage (REL); (C) Proline content; (D) Soluble sugar content. The data shown for the WT are the means of three replicates, whereas those for the transgenic plants are means of three different lines. Bars represent standard deviations (SDs), * and ** indicate significant differences relative to WT cotton plants at P < 0.05 and P < 0.01
