Determination of seed germination rates of transgenic Arabidopsis plants (a) Seeds of the wild-type (WT) and the L1 transgenic Arabidopsis plants (35S::GsoDA1-3) were germinated for five days. These seeds were treated by 0 mM, 125 mM and 175 mM NaCl, respectively. Bars = 2.5 mm. b-h Germination rates of WT and transgenic Arabidopsis seeds under salinity. The green column represents the WT, and the orange, pink and purple columns represent the transgenic lines L1, L2 and L3, respectively. Error bar: standard deviation. The red ** represent the significance at a P < 0.01 level in comparison to WT without treatment. The black * means significance at a P < 0.05 level, and the black ** represents the significance at a P < 0.01 level in comparison with WT at the same condition
