Intracellular redox status, antioxidant enzyme activity and proline content of the wild-type (WT, cv. Dongjin) and osnadk1 mutant under normal growth and drought stress conditions. Four-week-old plants were used for the drought treatment, and after 10 days of treatment, the leaves were used for the analysis. a-d The contents of NAD, NADH, NADP and NADPH. i-k The contents of GSH, GSSG and total glutathione (GSSG+GSH). m-o The contents of ASA, DHA and total ascorbic acid (ASA + DHA). e-h, j, p The ratios of NADH/NAD, NADPH/NADP, NADP(H)/NAD(H), NAD(P)H/NAD(P), GSH/GSSG, and ASA/DHA, respectively. q-w The enzyme activities of DHAR, MDHAR, GR, CAT, APX, POD and SOD, respectively. x The content of proline. All data are means ± SD and are representative of similar results from three independent experiments. Different letters above the bars represent significant differences by the Tukey method (P ≤ 0.05)
