Improved drought resistance of DcBCH1-overexpression transgenic A. thaliana plants. a Appearance of the WT and transgenic A. thaliana before and after 15 d of drought treatment. Scale bars = 2 cm. b MDA content of WT and transgenic A. thaliana (OE-3, OE-10, OE-13) after 15 d of drought treatment. c SOD activity of WT and transgenic A. thaliana (OE-3, OE-10, OE-13) before and after 15 d of drought treatment. d NBT staining for detection the accumulation of O2 in WT and transgenic A. thaliana (OE-3, OE-10, OE-13) leaves after 15d of drought treatment. Scale bars = 0.5 cm. e Survival rate of WT and transgenic A. thaliana (OE-3, OE-10, OE-13) after continuous drought and rewatering. Bars represent mean standard deviation (SD). Asterisks (*) indicate significant differences between transgenic plants (OE-3, OE-10, OE-13) and the WT plants (* P < 0.05; ** P < 0.01; *** P < 0.001). The letters above the bars indicate significant differences between the plant lines (P < 0.05, according to Tukey’s multiple range test)
