- Intervention effect Silicon improved morpho-physiological features, total protein and membrane stability under cadmium stress.
- Intervention effect Silicon reduced cadmium concentration in roots and shoots under cadmium stress.
- Intervention effect Silicon reduced iron concentration in roots and shoots under cadmium stress.
- Intervention effect Silicon did not significantly change MsPCS1 and MsMT2 expression under cadmium stress.
- Intervention effect Silicon did not significantly change phytochelatin accumulation under cadmium stress.
- Intervention effect Silicon reduced iron reductase activity in roots under cadmium stress.

- Mechanism Authors infer that limiting iron uptake via down-regulated iron acquisition alleviates cadmium toxicity.
- Intervention effect Silicon increased catalase, ascorbate peroxidase and superoxide dismutase activities.
- Intervention effect Silicon elevated methionine and proline under cadmium stress.
- Mechanism Authors suggest antioxidant changes may reduce H2O2 and defend against cadmium stress.
