Analysis of the enhanced drought tolerance in transgenic tobacco lines.

<p>(A) Phenotype of WT and TG tobacco lines after 3 weeks of drought treatment. (B) Rate of leaf yellowing. (C) Survival rate. (D) RWC content. (E) Proline content. (F) Soluble sugar content. (G) MDA content. (H) Tissue localization of O₂⁻ generation by NBT staining and tissue localization of H₂O₂ generation by DAB staining. The data present means ± SD of three experiments performed. Significant differences between the TG and control lines are indicated as *<i>p</i><0.05; **<i>p</i><0.01.
