Impaired stomatal function in max2 mutants. Four-week old wild-type Col-0 and max2 lines were assessed for their stomatal function. A) Stomatal conductance of four-week old non-treated Col-0, max2-1 and max2-4 plants were measured with a porometer. For each line 5 plants were used in each experiment and the results are shown as means ± SE. Experiments were repeated 5 times with similar results. **P < 0.01; two-tailed t test. B) Four-week old soil-grown Col-0 and max2 plants’ fresh weight change was measured by cutting the leaves and leaving them to dry for 4 h. For each line 5 plants were used in each experiment and the results are shown as means ± SE. Experiments were repeated 5 times with similar results.
