Overexpression of the McWRKY57-like gene improved osmolyte accumulation and antioxidant enzyme activities in transgenic Arabidopsis plants. A-C Proline, soluble sugar and soluble protein contents of WT and McWRKY57-like OE lines (OE-8 and OE-10) under normal and natural drought conditions. D MDA content of WT and McWRKY57-like OE lines (OE-8 and OE-10) under normal and natural drought conditions. E-G CAT, SOD and POD activities in leaves of WT and McWRKY57-like OE lines (OE-8 and OE-10) under normal and natural drought conditions. Data are means of the 3 replicates with SE. Different letters indicate significant differences at P < 0.05, as determined by one-way analysis of variance (ANOVA) with Tukey’s post-test
