Lipid peroxidation under salt and heavy metal stress (Cu): (a) Both TMT transplastomic and wild-type tobacco plants were grown on the MS medium supplemented with 0, 200, 300, 400 mM of NaCl. Lipid peroxidation was assayed in leaf samples after 4 weeks of stress by determining the amount of malondialdehyde (MDA). (b) TMT and wild-type tobacco plants were irrigated with standard nutrient solution containing 25 mM CuSO4. Control plants were grown similarly, but without CuSO4. Lipid peroxidation was assayed from leaf samples every 3 days by determining the amount of MDA. Data shown here is the mean and SD from five independent measurements. *, P<0.05, **,P <0.01
