Fig. 10: Schematic model of the MFS-type sugar transporter system coordinately contributing to subcellular sugar allocation in strawberry fruit.

The MFS transporters displayed are the family members with an expression profile that is significantly correlated with the sugar content in ripe fruits across the 19 strawberry varieties (Table 2). Subcellular localization was predicted by pSORT (Table 1). Pentagons represent symporters of SUT, STP, and INT; circles describe facilitators of SFP; squares represent antiporters of VGT and TST. Suc, sucrose; Glu, glucose; Fru, fructose; Hex, hexoses; Ino, inositol. For abbreviations, please refer to the text
