The mechanisms that regulate the loading of sucrose from the apoplast to the sieve elements by the sucrose–H+ symporter await characterization. Possible regulatory factors include the following:
a) The solute potential or, more likely, the turgor pressure of the sieve elements
b) Sucrose concentration in the apoplast
c) The available number of symporter protein molecules
