Assessment of relative H2O2 levels in tobacco plants under salinity stress. (A) Constitutive and salinity stress (200 mM NaCl) induced levels of H2O2 in leaves of WT as well as OsMT1e-P ectopically expressing lines (T1 - 15-D-old plants) were visualized by DAB staining. (B) Histograms depicting relative quantity of H2O2 in these leaves in terms of their colouration intensity. The data represents the means ± SE of three biological replicates (n = 3). Bars with different letters are statistically significant and those with same letter are not significantly different (p < 0.05).
