Abstract
Drought stress triggered the accumulation of malondialdehyde (MDA) and hydrogen peroxide (H2O2) both in non-Bt and Bt cotton with simultaneous production of antioxidant enzymes. And there was no significant difference between non-Bt and Bt cotton under drought stress. In contrast to this, we observed a significant reduction of Bt toxin proteins under 72 h of drought stress in Bt cotton.
