Figure 4. Short-term salt stress response of EcNAC1 transgenic tobacco plants.

15-day-old T₁ seedlings selected on hygromycin were inter-planted with wild-type seedlings on MS medium supplemented with 200 mM NaCl, and the observations were taken after seven days. (A) Phenotype, (B) Reduction in fresh weights over control and (C) Root elongation of transgenic tobacco plants under salt stress. Each bar value represents the mean ± sd (n = 6) of triplicate experiments (student’s t test; *P<0.05 versus wild-type).
