Other claims from this paper (10)
- Observation CMSII steady state photosynthesis was 20% to 30% lower at atmospheric CO2.
- Intervention effect High CO2 alleviated photosynthesis inhibition in CMSII.
- Intervention effect Low O2 alleviated photosynthesis inhibition in CMSII.
- Observation CMSII had prolonged photosynthesis induction, especially under photorespiratory conditions.
- Observation CMSII had increased extractable NADP-malate dehydrogenase activity.
- Observation CMSII had less capacity than wild type for dark glycine oxidation.
- Observation Gly decarboxylase capacity was not insufficient to explain reduced Gly oxidation.
- Association Light Gly to Ser ratio depended on photosynthesis similarly in CMSII and wild type.
- Mechanism The authors conclude that mitochondrial complex I is needed for optimal photosynthetic performance.
- Mechanism The authors conclude complex I prevents redox disruption when mitochondria oxidize respiratory and photorespiratory substrates simultaneously.
