text: In plants like Arabidopsis, where sucrose represents the main transport sugar and is loaded into the phloem via an apoplastic route (Gamalei, 1989; Haritatos et al., 2000), sugar transporters are involved in at least four steps of carbon distribution: (i) release of sucrose from the mesophyll cells to the apoplast, (ii) uptake of sucrose from the apoplast into the sieve element-companion cell complex, (iii) release of sucrose into the apoplast towards symplastically isolated sink-tissues like for example pollen or embryos, and (iv) re-uptake of sucrose into these tissues (Lemoine, 2000).
