Vacuolar membrane proton / sugar antiporter protein and its use to increase sucrose concentration in plant saccharose storage organs

摘要

The present invention is for producing a vacuolar membrane proton / sugar antiporter protein, particularly a vacuolar membrane proton / saccharose antiporter protein, a nucleotide sequence encoding the protein, and a transgenic plant exhibiting an increase in saccharose concentration. Relating to its use. The present invention further identifies a method for producing a transgenic plant exhibiting an increase in sucrose concentration, a method for increasing the saccharose concentration in the plant, and a plant suitable for producing an increase in saccharose concentration. Including methods for:
