General Information

General Information Comment Organism
physiological function deletion of isoform HPR3 results in slightly altered leaf concentrations of the photorespiratory intermediates HP, glycerate, and glycine, indicating a disrupted photorespiratory flux, but not in visible alteration of the phenotype.The combined deletion of of isoforms HPR1, HPR2, and HPR3 causes increased growth retardation, decreased photochemical efficiency, and reduced oxygen-dependent gas exchange in comparison with the hpr1hpr2 double mutant. Isoform HPR3 could provide a compensatory bypass for the reduction of hydroxypyruvate and glyoxylate within the chloroplast Arabidopsis thaliana
