Performance of transgenic plants and wild-types under normal and Cu stress conditions. (A) Left panel, seedlings reared under normal conditions (0 μM CuCl₂) for 30 days; right panel, seedlings exposed to 50 μM CuCl₂ for 30 days. WT, wild-type Arabidopsis thaliana; L-5 and L-7, transgenic lines 5 and 7. (B) Survival rates of plants after growth under Cu stress for 30 days. Each column represents an average of three replicates, and bars indicate ± standard deviation (SD); and ** p < 0.01 indicate significant differences compared to wild-type T plants under the same conditions determined using Student’s t-tests.
