Glycolate stimulation of oxygen evolution during photosynthesis.
Glycolate and glyoxylate stimulated 100% to 300% the rate of oxygen evolution by Scenedesmus in the light in the absence of added carbon dioxide. This stimulation occurred either aerobically or anaerobically, and was sensitive to CMU. Aerobic dark respiration was stimulated 25% to 100% by glycolate. This phenomenon was best demonstrated with synchronized Scenedesmus at the stage of cell divisio...
متن کاملGlycolate, glycine, serine, and glycerate formation during photosynthesis by tobacco leaves.
Formation of d-phosphoglycerate, glycolate, glycerate, and serine by tobacco leaves was analyzed between 4 and 60 set of 14C02 fixation during photosynthesis. With decreasing time, the percentage of the total 14C incorporated into 3phosphoglycerate increased; the percentage into the other compounds, including glycolate, decreased to nearly zero. At 4 or 11 set 3-phosphoglycerate and glycerate w...
متن کاملOverexpression of Glycolate Oxidase Confers Improved Photosynthesis under High Light and High Temperature in Rice
While glycolate oxidase (GLO) is well known as a key enzyme for the photorespiratory metabolism in plants, its physiological function and mechanism remains to be further clarified. Our previous studies have shown that suppression of GLO in rice leads to stunted growth and inhibited photosynthesis (Pn) which is positively and linearly correlated with decreased GLO activities. It is, therefore, o...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Effect of glycidate on glycolate formation and photosynthesis in isolated spinach chloroplasts.
Glycidate (2,3-epoxypropionate) increased CO(2) photoassimilation in intact spinach (Spinacia oleracea L.) chloroplasts in the presence of various inhibitors of photosynthesis, including O(2), arsenite, azide, iodo-acetamide, and carbonylcyanide 3-chlorophenylhydrazone. Although the mechanism by which glycidate enhances photosynthesis is obscure, the stimulatory effect cannot be ascribed to eit...
