Functional characterization of GhSWEET42 using yeast sugar transport-defective strains SUSY7/ura3 and EBY.VW4000. (A) Complementation of sucrose transport deficiency in the SUSY7/ura3 yeast mutant by GhSWEET42 (positive control: AtSUT4; negative control: empty vector). (B) Complementation of hexose transport deficiency in the EBY.VW4000 yeast mutant by GhSWEET42 (positive control: yeast HXT7; negative control: empty vector).
