Title

Other claims from this paper (8)
- Intervention effect Aluminum stress elevated malondialdehyde, electrolyte leakage, and superoxide anion in tomato roots and leaves.
- Intervention effect Aluminum stress elevated hydrogen peroxide and aluminum concentration in tomato roots and leaves.
- Intervention effect Melatonin increased antioxidant enzyme activity in aluminum-stressed tomato.
- Mechanism Melatonin lowered internal ROS and protected tomato cell membranes and photosynthetic pigments from aluminum toxicity.
- Intervention effect Melatonin increased phytochelatins, glutathione, and nitric oxide in leaves and roots under aluminum contamination.
- Mechanism Increased thiols and nitric oxide reduced aluminum translocation to leaves through immobilization in roots.
- Intervention effect The nitric oxide scavenger carboxy-PTIO suppressed melatonin protection in tomato.
- Mechanism The authors concluded that melatonin facilitates tomato adaptation to aluminum stress by regulating internal nitric oxide.
