Research Abstract	We found that the activity of sedoheptulose-1,7-bisphosphatase (SBPase) was regulated by not only ferredoxin/thioredoxin system, but also by protein modification such as phosphorylation. On the other hand, we found that CP12, regulator of GAPDH and PRK in the Calvin cycle, functioned to protect photosynthetic apparatus under photooxidative stress.
