NUCLEIC ACIDS CODING FOR VACUOLAR INVERTASES, VEGETAL CELLS AND PLANTS CONTAINING SAID NUCLEIC ACIDS AND THE USE THEREOF

摘要

The invention relates to a nucleic acid molecule coded for a vacuolar invertase and the use thereof for modifying the metabolism of vegetal saccharose, particularly in the vacuole of the cell of a vegetal storage organ. The invention also relates to a fragment of the nucleic acid molecule, a vector containing the nucleic acid molecule, or a fragment thereof and a host cell, particularly a vegetal cell which contains the nucleic acid molecule or a fragment thereof. The invention also relates to a transgenic plant, a method for producing a transgenic plant and a method for modifying the saccharose metabolism of a plant, particularly a section of a plant.
