    Peroxisomal hydroxypyruvate reductase is not essential for photorespiration in Arabidopsis but its absence causes an increase in the stoichiometry of photorespiratory CO2 release (2011), Photosynth. Res., 108, 91-100.

General Information

General Information Comment Organism
physiological function rates of photosynthesis under photorespiratory conditions are slightly reduced in mutant plants lacking isoform hpr1 expression or additionally lacking both of the peroxisomal malate dehydrogenase genes, mutant pmdh1pmdh2hpr1. The CO2 compensation points increase under photorespiratory conditions in both mutants. The increase in CO2 compensation points in the hpr1 and pmdh1pmdh2hpr1 plants is not associated with changes in mitochondrial respiration but with an increase in the non-respiratory CO2 released per Rubisco oxygenation reaction Arabidopsis thaliana
