Fig. 2.

Response of different Arabidopsis mutants to salt stress. Seeds of the indicated genotypes were incubated at 4 °C for 1 d on one-half MS solid medium with different concentrations of NaCl, then placed at 23 °C for 5 d, after which germination was scored. As shown, (A) med25, (B) dreb2a, (C) zfhd1, and (D) myb-like. Each genotype was treated independently. The experiments were performed using four plates of 49 seedlings for each treatment and genotype. Data represent mean ± standard deviation of at least three individual experiments.
