Results of salinity tolerance analysis of wild-type and transgenic rice plants expressing JcHDZ16. a Wild-type and transgenic plants before and after exposure to 150 mM NaCl, and after a 12-day recovery period (representative images of plants in an experiment with three biological replicates). b Survival rates of wild-type and transgenic plants after the 12-day period. c-g Proline contents, relative electrolyte leakage (REL), MDA contents and activities of catalase (CAT) and (g) superoxide dismutase (SOD) in leaves before and after salt treatment. Data in c-g: means of n = 20 ± SD from three independent experiments, asterisks above the bars indicate significant differences from wild-type controls at p < 0.01 (c-e) or p < 0.05 (f, g). h Relative expression levels of salt stress-responsive genes, in an experiment with three biological replicates, each with two technical replicates (means of n = 6 ± SD, asterisks above the bars indicate significant differences from wild-type controls at p < 0.01)
