2 Figure 1 Model of sucrose transport in a leaf vein. Sucrose synthesized in mesophyll cells moves into phloem parenchyma (PP) cells through plasmodesmata. SWEET proteins localized on the plasma membrane of phloem parenchyma cells efflux sucrose into the phloem apoplast. Sucrose transporters (SUTs) on the plasma membrane of the sieve element (SE)-companion cell (CC) complex uptake sucrose from the apoplast, thereby concentrating sucrose into sieve elements.
