Abstract

The invention relates to tonoplast proton/sugar antiporter proteins, more particularly tonoplast proton/saccharose antiporter proteins, the nucleotide sequences which encode them and uses thereof for producing transgenic plants with an increased saccharose concentration. The invention also includes methods for producing transgenic plants with an increased saccharose concentration, methods for increasing the saccharose concentration in plants, and for identifying plants which are suitable for creating a higher saccharose concentration.
