The invention relates to tonoplastoid proton / sugar antiporter proteins, in particular to tonoplastic proton / sucrose antiporter proteins, to the nucleotide sequences encoding them and their uses for producing transgenic plants having an increased sucrose concentration. The invention also includes methods for producing transgenic plants having an increased sucrose concentration, methods for increasing the sucrose concentration in plants, and for identifying plants which are capable of producing a higher sucrose concentration. |
