Under the background of Cd (50 μmol·L) stress, we added ethylene precursor ACC (100 μmol·L), ACC + nitric oxide synthase (NOS) inhibitor L-NNA (200 μmol·L), ACC + nitrate reductase (NR) inhibitor Tu (1 mmol·L), ACC + nitric oxide (NO) scavenger PTIO (200 μmol·L), NO donor SNP (500 μmol·L), SNP + ethylene signal inhibitor STS (100 μmol·L) to examine their effects on the damage degree of leaves and response mechanisms of AsA-GSH cycle in lotus 'Weishanhuhonglian'. Results showed toxic symptom of lotus leaves under Cd stress. The relative conductivity, malondialdehyde (MDA), as well as ascorbic acid (AsA) and glutathione (GSH) contents were significantly increased, but the activities of ascorbate peroxidase (APX), glutathione reductase (GR), monodehydroascorbate reductase (MDHAR) and dehydroascorbate reductase (DHAR) were obviously decreased.

- Heme oxygenase-1 (HO1) found in animals and plants protects against cell damage from oxidants, and this study focused on the wheat HO1 gene, TaHO1.
- TaHO1 encodes a protein similar to maize HO1 and clusters with other plant HO1-like sequences, showing significant activity in converting heme to biliverdin IXa under optimal conditions.
- The expression of TaHO1 can be triggered by various stress-related compounds, indicating its potential role in helping plants respond to abiotic stresses.
