Responses of the wild-type and transgenic plants to salt treatment.

<p>(A) Phenotypes of wild-type, W69 and W106 seedlings under NaCl treatment. Three-day-old seedlings of four transgenic lines and wild-type <i>Arabidopsis</i> were planted on MS media with added NaCl (150 mM) for 15 d. (B) Comparative root lengths of wild-type, W69 and W106 seedlings grown on MS agar plates containing different concentrations of NaCl for 15 d after germination. Data are means ±SD of three independent experiments. Asterisks indicate a significant difference (*P<0.05; Student's t-test) relative to wild-type control.
