Responses of transgenic Arabidopsis and WT plants grown in pots under drought and salt stresses. (a) Phenotypes of transgenic lines and WT grown for 4 weeks under normal condition, 2 weeks under normal condition, and 2 weeks under 300 mM NaCl treatment or 2 weeks under normal conditions and 2 weeks under drought stress followed by 2 days of re-watering; (b) ABA content in transgenic lines and WT under the normal or stress condition shown in (a); (c) proline content in transgenic lines and WT under the normal or stress condition shown in (a); (d) SOD activity in transgenic lines and WT under the normal or stress condition shown in (a); (e) MDA content in transgenic lines and WT under the normal or stress condition shown in (a); and (f) H₂O₂ content indicated by DAB staining in transgenic lines and WT under the normal or stress condition. Data are presented as means ± SE (n = 3); ** indicate a significant difference at p < 0.01.
