Maximal activities of MnSOD (A), FeSOD1 (B), and CuZnSOD1 (C) in wild-type N. tabacum and three transgenic lines with altered AOX amount, in both well-watered and moderate drought-stressed plants. Data are the mean ± se of six independent experiments. Activities are relative to that of the well-watered wild-type activity, which was set to 1. Within each treatment, plant lines not sharing a common letter above the data bar are significantly different from one another (P < 0.05). WT, Wild type.
