additional information | insertional mutants of PMG1 and duble mutants of PMG1 and PMG2 are generated. While single mutants are indistinguishable from wild-type in all plant phenotypes assayed, double mutants have no detectable iPGAM activity and show defects in blue light-, abscisic acid-, and low CO2-regulated stomatal movements | Arabidopsis thaliana |

malfunction | PMG1/PMG2 double mutants have no detectable iPGAM activity and show defects in blue light-, abscisic acid-, and low CO2-regulated stomatal movements. Vegetative plant growth is severely impaired in the double mutants and pollen is not produced, phenotypes, overview | Arabidopsis thaliana |
physiological function | 2,3-biphosphoglycerate-independent phosphoglycerate mutase is a key enzymatic activity in glycolysis and catalyses the reversible interconversion of 3-phosphoglycerate to 2-phosphoglycerate, functions of iPGAMs and glycolysis in stomatal function and plant growth, overview. Both isozymes PMG1 and PMG2 and glycolytic activity are critical for guard cell function and fertility | Arabidopsis thaliana |
