WebbThis source‐to﹕ink carbon allocation occurs in the phloem and requires the loading of sucrose into the leaf phloem and, at the sink end, its import into the growing embryo. Both tasks are achieved through the function of SUT sucrose transporters.

This translocation occurs via the plasma membrane of the sieve tubes, which are composed of a series of connected sieve elements. The mechanism of the longitudinal assimilate movement in sieve tubes has been explained by two different models of phloem loading: 1. Symplastic loading, 2. Apoplastic loading.
