Analysis of ROS levels, MDA contents, electrolyte leakage, and CAT activity in the roots of both OsERF106MZ-overexpressing transgenic rice seedlings and TNG67 seedlings. a NBT staining. b MDA content. c Electrolyte leakage. d CAT activity. These physiological assays were carried out as previously described [31]. The values are the mean ± SE of five biological replicates, each with two technical replicates. The asterisks indicate significant differences (*, P < 0.05 and **, P < 0.01) in comparison to the corresponding WT based on Student’s t test. For these assays, seedlings were grown on basal medium for 7 days and then transferred to basal medium containing 0 or 150 mM NaCl for an additional day
