Rice (Oryza sativa) seeds were imbibed for 3 days and the seedlings were further incubated for 8 days in the presence of either air or nitrogen. In aerobiosis, the specific activity of pyrophosphate:fructose 6-phosphate 1-phosphotransferase and that of the ATP-dependent phosphofructokinase increased about fourfold. In anaerobiosis, the specific activity of ATP-dependent phosphofructokinase remained stable, whereas that of pyrophosphate:fructose 6-phosphate 1-phosphotransferase increased as much as in the presence of oxygen and there was also a fourfold increase in the concentration of fructose 2,6-bisphosphate, a potent stimulator of that enzyme. These data suggest a preferential involvement of pyrophosphate:fructose 6-phosphate 1-phosphotransferase rather than of ATP-dependent phosphofructokinase in glycolysis during anaerobiosis.
