摘      要：The majority of higher plants use sucrose as their main mobile carbohydrate. Proton-driven sucrose trans- porters play a crucial role in cell-to-cell and long-distance distribution of sucrose throughout the plant. A very negative plant membrane potential and the ability of sucrose transporters to accumulate sucrose concentrations of more than 1 M indicate that plants evolved transporters with unique structural and functional features. The knowledge about the trans- port mechanism and structural/functional domains of these the current knowledge about the biophysical properties of nano-machines is, however, still fragmentary. In this review, plant sucrose transporters is summarized and discussed.
