ENERGY BALANCE. “Sugar sensing and signaling is an important part of mechanisms orchestrating carbon assimilation, assimilate storage and consumption based on precise sensing and integration of signals on energy balance at different levels. Arabidopsis plants not only tune sugar utilization and growth according to assimilate supply, but they also modulate the deposition of storage carbon (starch) according to “expected” need during the night.”
