Other claims from this paper (8)
- Intervention effect At 900 mg kg⁻¹ lead, the plant developed structurally better than at lower concentrations.
- Observation The plant transferred lead into its structures and retained it mainly in roots.
- Intervention effect ATP levels increased 62% at Pb150 relative to control.
- Intervention effect ATP levels increased 77% at Pb900 relative to control.
- Intervention effect Catalase activity was elevated in all plant parts at Pb900.
- Intervention effect Ascorbate peroxidase activity was elevated in all plant parts at Pb900.
- Mechanism Guaiacol peroxidase was highly active and was linked to barriers reducing metal translocation.
- Observation The authors concluded BRS323 can thrive under lead stress.
