Relationship between CO2 Assimilation, Photosynthetic Electron Transport, and Active O2 Metabolism in Leaves of Maize in the Field during Periods of Low Temperature
TL;DR: Measurements of the quantum efficiencies of photosynthetic electron transport through photosystem II (phiPSII) and CO2 assimilation (phiCO2) were made simultaneously on leaves of maize crops in the United Kingdom during the early growing season, when chilling conditions were experienced, supporting the hypothesis that the relative flux of photosynthesis reducing equivalents to O2 via the Mehler reaction is higher when leaves develop under chilling conditions.

Consequences of LHC II deficiency for photosynthetic regulation in chlorina mutants of barley.
TL;DR: It is concluded that LHC II is important to balance the distribution of excitation energy between PS I and PS II populations over a wide range of photon flux densities and may also be important in determining the quantum efficiency of PS II photochemistry by reducing the rate of quenching ofexcitation energy in the PS II primary antennae.

Evaluation of the role of State transitions in determining the efficiency of light utilisation for CO2 assimilation in leaves.
TL;DR: It is concluded that State transitions in C3 leaves are associated with phosphorylation-induced modifications of the PS II antennae, but these changes do not serve to optimise the use of light absorbed by the leaf for CO2 assimilation.

TL;DR: Photorespiration appears to buffer the quantum efficiency of CO2 assimilation from changes associated with decreases in the rate ofCO2 fixation resulting from imbalances in PPFD absorption by PSI and PSII.
