Physiological and transport data are presented in support of a symplastic pathway of phloem unloading in importing leaves of Beta vulgaris L. ('Klein E multigerm'). The sulfhydryl reagent ...
High levels of mRNA for the sucrose-H + symporter PmSUC2 have been found in the vascular bundles of petioles from Plantago major. The possible role of PmSUC2 in phloem loading was studied with ...
