Sucrose storage in sugarcane stem parenchyma is an example of a highly regulated process, where anatomical features, metabolic reactions
Fig.8: Scheme of sucrose compartmentation between cytosol and vacuole in suspension cells (top) and internode parenchyma cells (bottom). When the intravacuolar degradation by SAI has become low, sucrose will be safe in the vacuole if the permeation rate through the tonoplast is low (as is the case in storage cells), whereas in suspension cells the rapid equilibration through the tonoplast will subject vacuolar sucrose indirectly to the action of cytosolic neutral invertase.
