FIGURE 7.

Reduced NaCl and PEG tolerance in sapk2 mutant plants. (A) Phenotype before 25% PEG stress, after 25% PEG stress and recovery for 7 days of sapk2 mutants and wild-type plants. (B) Survival rates corresponding to (A). (C) Phenotype before 175 mM NaCl stress, after 175 mM NaCl stress and recovery for 7 days of sapk2 mutants and wild-type plants. (D) Survival rates corresponding to (C). Analysis for PEG and NaCl stress was repeated three times. In each repeated experiment, at least 40 plants were used for each individual line. One representative picture was shown here. Error bars indicate SD from three independent RNA extracts. ^∗∗indicate statistically significant differences between mutant lines and wild type plants (P < 0.01).
