Figure 4

Enhanced resistance to drastic dehydration and oxidative stress conditions in the 35S:A9/A4a seedlings. Leaf-survival and whole seedling survival was evaluated. (A) Tolerance to severe dehydration. Data correspond to 17 independent experiments (n = 162) performed with the four sibling 35S:A9/A4a and 35S:A9 line pairs. (B) Tolerance to drastic oxidative stress conditions (treatments with 300 mM H2O2 for 24 h). Data correspond to 10 independent experiments (n = 100) performed with the same sibling line pairs. The dashed line in (A) and (B) separates the data that are described by the y-axis labels placed respectively to right or left in these panels. Data are mean values ± SE. Asterisks denote statistically significant differences (P ≤ 0.01). (C) Representative results shown for survival of leaves and whole seedlings after the H2O2 treatments. Scale bars, 1 cm.
