Estimation of H₂O₂, proline and MDA in transgenic tobacco lines under different stress condition.

<p>Comparison of (a) H₂O₂, (b) Proline and (c) MDA content of wild type (WT) and T₁ transgenic lines (L2, L4, L6 and L13) grown in hydroponic (control) and treated with salt (200 mM NaCl), osmotic (10% PEG), Zn (1 mM), Cu (0.5 mM) and Cd (0.5 mM) stress. Graph represents the mean ± SD (of three replicates; n = 3) followed by similar letters are significantly different according to Tukey HSD at <i>P<0.05</i>.
