Ectopic expression of AmDHNs in Arabidopsis affects salt tolerance; (a) seed germination rates of the wild type and AmDHN transgenic plants under different concentrations of NaCl; (b) growth performance of the wild type and AmDHN transformants grown under normal and salt treatment conditions; (c) survival rate of salt-treated plants. AmDHN154 transformed lines: 2-10-2, 2-10-39, 2-11-2. AmDHN132 transformed lines: 4-10-19, 4-10-30, 4-8-18. AmDHN200 transformed lines: 7-4-29, 7-5-47, 7-6-59. Each column is the mean of three independent experiments and bars represent the standard error of the mean. The different letters denote significant differences (p < 0.05) according to ANOVA results.
