Expression of salt tolerance-related genes in wild-type and transgenic Arabidopsis.
a–e The expression variation of SOS2 (a), SOS3 (b), ADH (c), P5CS1 (d) and FRY1 (e) in the indicated transgenic Arabidopsis lines in comparison with wild-type Arabidopsis (WT). f The 35::GsoDA1-8 transgenic Arabidopsis seedlings were also treated by 250 mM NaCl. Expressions of each gene in wild-type Arabidopsis (dark blue and light blue columns) were set as controls (CK). The ACTIN gene was used as an internal control. The experiments were performed using three independent biological samples. Error bar: standard deviation. The * means significance at a P < 0.05 level, and the ** represent the significance at a P < 0.01 level
