The phenotype of CdWRKY2 overexpression transgenic bermudagrass grown in hydroponic culture. A single branch of the CdWRKY2 overexpression lines (CdOE13 and CdOE12) and the transgenic negative control line (WT) was planted in soil for approximately 7 days. The roots of each plant were washed clean and then supplied with 0 mM NaCl (CK) or 200 mM NaCl (Salt) for 20 days in hydroponic culture. (A) Images of the overexpression lines and control line grown under CK and salt conditions. Bar = 10 cm. (B) Images of roots of plants under CK and salt conditions. (C) Relative increment of biomass before and after treatment. (D) Withering rate. (E) Relative increase of total PR length before and after treatment. (F) Relative increase of total roots length before and after treatment. (G) Relative increase of total roots number before and after treatment. Data are the means ± SD of three biological replicates. Two-way ANOVA test was used and the data were further compared by Tukey’s post‐hoc test. Significant differences at p < 0.05 were shown by different letters above the columns.
