Other claims from this paper (11)
- Intervention effect Photoinhibition was faster in Cu-treated bean leaves than controls.
- Observation Thylakoids from Cu-treated plants did not show high photoinhibition sensitivity.
- Observation Chloroplast Cu concentration was lower than leaf Cu concentration in treated plants.
- Intervention effect Excess Cu caused no severe oxidative stress, antioxidant collapse or photoprotection loss.
- Intervention effect Cu treatment lowered leaf chlorophyll concentration.
- Intervention effect Adding excess Fe with Cu overcame chlorophyll loss and photoinhibition sensitivity.
- Intervention effect Fe addition lowered leaf Cu concentration.
- Mechanism The authors propose Cu competition with Fe uptake as a cause of iron deficiency and photosensitivity.
- Association Susceptibility to photoinhibition was causally related to leaf optical density across plant species.
- Association Photoinhibition rate was directly proportional to light intensity.
- Observation Photosynthesis saturated at moderate light.
