Light Compensation Points and Photorespiration
Nature, 1970SOME results of an investigation into light compensation points of photosynthesizing leaves are relevant to arguments about the occurrence or absence of photorespiration in illuminated leaves of species which do not release carbon dioxide into carbon dioxide-free air, and which have a carbon dioxide compensation point (Γ) close to zero1–3.

Protein phosphorylation and photorespiration
Plant Biology, 2013AbstractPhotorespiration allows the recycling of carbon atoms of 2‐phosphoglycolate produced by ribulose‐1,5‐bisphosphate carboxylase/oxygenase (Rubisco) oxygenase activity, as well as the removal of potentially toxic metabolites. The photorespiratory pathway takes place in the light, encompasses four cellular compartments and interacts with several ...

Biochemical dissection of photorespiration
Current Opinion in Plant Biology, 1999Progress has been made in the understanding of photorespiration and related proteins (Rubisco, glycolate oxidase and glycine decarboxylase) in the context of recent structural information. Numerous shuttles exist to support transamination, ammonia refixation and the supply or export of reductants generated or consumed (via malate-oxaloacetate shuttles)

Kinetic Modeling of Photorespiration
2017Dynamic systems modeling is a method to study systematic properties of a complex system. The basic principles, procedures, and tools available to develop a dynamic systems model of complex metabolic processes are detailed. Here, a photosynthetic carbon metabolism model, which includes the Calvin Benson cycle, photorespiration, and starch and sucrose ...

Photorespiration during C4 photosynthesis
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1971Abstract 1. This paper describes aspects of the synthesis and metabolism of glycolate as factors controlling the apparent absence of CO2 evolution in the light (photorespiration) in the leaves of plants which photosynthesise via the C4 dicarboxylic acid pathway (C4 plants).

Metabolic Engineering of Photorespiration
2017The introduction of two alternative glycolate catabolic pathways in the chloroplasts of Arabidopsis thaliana rendered plants with increased biomass. To introduce these synthetic pathways, the selected genes were stepwise integrated in the nuclear genome of wild-type plants.

Glyoxylate decarboxylation during photorespiration
Planta, 1978At 25° C under aerobic conditions with or without gluamate 10% of the [1-(14)C]glycollate oxidised in spinach leaf peroxisomes was released as (14)CO2. Without glutamate only 5% of the glycollate was converted to glycine, but with it over 80% of the glycollate was metabolised to glycine.

Barley Photorespiration Mutants
1987Photorespiration, the light- and O2_dependent release of CO2 from the leaves of certain species, is regarded as the inevitable consequence of the oxygenase activity of ribulose bisphosphate carboxylase/oxygenase, Rubisco [1]. Some authors have suggested that, inevitable or not, the process may have a useful function [2].
