Photorespiration: metabolic pathways and their role in stress protection. [PDF]
, 2000 Photorespiration results from the oxygenase reaction catalysed by ribulose-1,5-bisphosphate carboxylase/oxygenase. In this reaction glycollate-2-phosphate is produced and subsequently metabolized in the photorespiratory pathway to form the Calvin cycle ...

Photorespiration in C4 grasses remains slow under drought conditions [PDF]
, 2008 The CO(2)-concentrating mechanism present in C(4) plants decreases the oxygenase activity of ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco) and, consequently, photorespiratory rates in air.

Frontiers in Bioengineering and Biotechnology, 2021 Synthetically designed alternative photorespiratory pathways increase the biomass of tobacco and rice plants. Likewise, some in planta–tested synthetic carbon-concentrating cycles (CCCs) hold promise to increase plant biomass while diminishing ...

Intraspecific Measurements of Photorespiration [PDF]
Plant Physiology, 1972 The relative magnitudes of (a) CO(2) compensation concentration, (b) zero CO(2) intercept of the CO(2) response curve, (c) O(2) suppression of net photosynthesis, (d) differential (12)CO(2) and (14)CO(2) uptake, and (e) (14)CO(2) efflux into CO(2)-free air were determined in the dry bean (Phaseolus vulgaris L.) varieties Michelite-62 (M-62) and Red ...

Transport Proteins Enabling Plant Photorespiratory Metabolism
Plants, 2021 Photorespiration (PR) is a metabolic repair pathway that acts in oxygenic photosynthetic organisms to degrade a toxic product of oxygen fixation generated by the enzyme ribulose 1,5-bisphosphate carboxylase/oxygenase. Within the metabolic pathway, energy

Measurement of Photorespiration in Algae [PDF]
Plant Physiology, 1982 The rates of true and apparent photosynthesis of two unicellular green algae, one diatom and four blue-green algae were measured in buffer at pH 8.0 at subsaturating concentrations of dissolved inorganic carbon (13-27 micromolar). Initial rates of depletion from the medium of inorganic carbon and (14)C activity caused by the algae in a closed system ...

Plants, 2020 The oxidation of P700 in photosystem I (PSI) is a robust mechanism that suppresses the production of reactive oxygen species. We researched the contribution of photorespiration to the oxidation of P700 in wheat leaves.

13C Isotope Labelling to Follow the Flux of Photorespiratory Intermediates
Plants, 2021 Measuring the carbon flux through metabolic pathways in intact illuminated leaves remains challenging because of, e.g., isotopic dilution by endogenous metabolites, the impossibility to reach isotopic steady state, and the occurrence of multiple pools ...
