Overexpression of HbDHN1 and HbDHN2 enhances osmotic tolerance in Arabidopsis. (A) Expression levels of HbDHN-overexpressing A. thaliana. (B) The seedlings were transferred onto 1/2 MS medium containing 200 or 300 mM mannitol. Phenotypes were observed; (C) The root lengths were measured at 7 days after transferring. Data represent mean values ± SE obtained from three independent experiments. Different letters indicate a significant difference at the level of p < 0.05. Four columns in a block (WT and three transgenic lines) were analyzed for significant differences.
