Other claims from this paper (12)
- Mechanism The proton motive force acts as a central regulator of photosynthetic performance and photoprotection in plants.
- Intervention effect Bicarbonate depletion impaired the donor and acceptor sides of PSII in Limnospira maxima.
- Intervention effect After bicarbonate depletion, transport of more than two electrons from QA to QB in Limnospira maxima was not possible.
- Intervention effect Bicarbonate depletion altered Cyt b6f reoxidation kinetics in Limnospira maxima.
- Intervention effect Bicarbonate depletion delayed P700 reoxidation kinetics in Limnospira maxima.
- Mechanism Bicarbonate depletion suggests impaired carbon fixation and donor-side limitation at PSI.
- Observation Cys168 and Cys190 are crucial redox-sensitive residues of GSAAT in Arabidopsis.
- Intervention effect Oxidation-induced disulfide formation reduces GSAAT activity in Arabidopsis.
- Intervention effect Reduction of the disulfide increases GSAAT activity in Arabidopsis.
- Method / resource A/Ca values gave a superior fit to measured respiration than A/Ci in crops.
- Association The relationship between ambient CO2 and photorespiration or mitochondrial respiration is dose-dependent and non-linear in crops.
- Method / resource Model-derived photorespiration and respiration disagree with measured values, revealing limitations of current models for crops.
