Abstract
With low-P treatment of maize, the level of sucrose phosphate synthase (SPS) protein decreased to 15% of the control, while the “Vmax” activity stayed relatively high (100–80% of the control) and the substrate limiting activity increased about 2 fold in the leaves. These results suggest that leaf phosphate status has dual effects on the amount of SPS protein and the activation state of SPS.
