N2 - We study the regulation of sucrose level by shifting the internal circadian related rates of sucrose export, and synthesis and degradation of starch in a leaf. We allow these shifts to change dynamically in order to reduce sucrose starvation in several light/dark cycle conditions. The model successfully reduces starvation in the leaf and show many features similar to observations. Finally we include the leaf model in a phloem network containing a root and a meristem, the three of them connected and exchanging sucrose by osmotic pressure driven flow. The global model allows sucrose sharing among organs and an overall lower starvation level.
