FlbZIP12 overexpression enhances drought tolerance. (A) Transformation of Tartary buckwheat hairy roots. (B) Relative FlbZIP12 expression in 28-d-old hairy root lines (#2, #5, and #9) and control plants (transformed with the empty vector). (C-E) Oxidative response after 25% PEG6000 treatment. (C) SOD activity; (D) CAT activity; (E) MDA content. (F, G) Relative expression levels of stress-related genes in hairy root lines treated with 25% PEG6000 for 5 d The expression level of FlbZIP12 in the empty vector control was set to 1 (B, F, G). FlH3 was used as an internal control (B, F, G). Values are means ± SD (n = 3, BG). Significant differences between the empty vector (EV) control and FlbZIP12-overexpressing hairy root lines are shown (*P < 0.05; **P < 0.01; one-way ANOVA with Tukey’s post-test).
