To clarify the mechanism of sugar accumulation in fruits, we chose tomato as a model plant and analyzed its sugar transporters comprehensively. We found 20 sugar transporters in tomato and the most of them expressed in fruit. We determined that AZT, SFP and VGT localize in vacuolar membrane. Although we succeeded to produce their transgenic yeasts and tomato plants, we could not see sugar transport activity in the yeasts and change in sugar content in their fruits.
