Other claims from this paper (10)
- Intervention effect Arabidopsis thaliana downregulated Cu/ZnSOD under copper limitation.
- Intervention effect Brassica juncea downregulated Cu/ZnSOD under copper limitation.
- Intervention effect Lycopersicum lycopersicum downregulated Cu/ZnSOD under copper limitation.
- Intervention effect Zea mays downregulated Cu/ZnSOD under copper limitation.
- Intervention effect FeSOD expression rose under copper limitation in all tested species except Zea mays.
- Observation FeSOD was undetectable in Zea mays under copper limitation.
- Intervention effect Copper limitation did not affect plastocyanin accumulation in most tested species.
- Observation Zea mays was the exception to unchanged plastocyanin accumulation under copper limitation.
- Method / resource Cu/ZnSOD and FeSOD expression were suggested as indicators of impending copper deficiency.
- Mechanism The authors infer that switching from Cu/ZnSOD to FeSOD can maintain superoxide scavenging while saving copper for plastocyanin.
