Phenotypic analysis of 70-day-old WT and SikCOR413PM1-overexpressing cotton Seedlings under cold and drought stress. (A) Phenotype of WT and OE-4, OE-5, and OE-7 transgenic plants after exposure to 4 °C for 24 h and 48 h; (B) Phenotype of WT and OE-4, OE-5, and OE-7 transgenic plants after exposure to drought for 14 and 21 days; (C) Fresh weight and (D) dry weight of the plants under stress. The data shown are the average of three independent biological replicates. Bars represent standard deviations (SDs). * and ** indicate significant differences relative to WT cotton plants at P < 0.05 and P < 0.01, respectively (In the phenotypic analysis figure of cotton cold stress, the cotton seedlings in each figure are wild type, OE-4, OE-5, and OE-7 transgenic plants from left to right)
