| Research Abstract |
Using Ananas comosus and Dendrobium phalaenopisis, involvements of glycolysis and mitochondrial respiration to CAM photosynthesis were studied. It was appeared that the distribution of pyruvate Pi dikinase (PPDK) in the cell regulated the electron flow in the mitochondrial respiration to cytochrome C oxidase. In addition, diurnal changes of glycolysis gene expression were classified to three groups, relating to CO2 fixation in night and decarboxylation of malate in day, and not showing the diurnal changes of CAM. Especially, it was suggested that the diurnal change of glyceraldehyde 3-phosphate (GAPDH) dehydrogenase gene expression related to the diurnal gas exchange of CAM photosynthesis.
