The IL, MDA, H₂O₂ content and the activities of SOD and CAT in WT and transgenic lines with the same water status under drought conditions.

<p>The WT and transgenic lines were cultured in MS medium under a 16 h light/8 h dark cycle at 25°C for one week, and then the plants were transplanted to containers filled with a mixture of soil and sand (3∶1) where they were regularly watered for two weeks. Three-week-old tobacco plants were deprived of water for 16 d. Tobacco leaves were sampled from WT and transgenic lines under drought stress to detect the RWC (A). When WT with 8 d drought treatment and transgenic lines with 16 d drought treatment, they maintained same water status and then the IL (B), MDA (C), H₂O₂ (D), SOD (E) and CAT (F) were measured.
