  • Modified ppase expression in sugar beet
    Publication number: 20070067873
    Abstract: The present invention relates to a process and means for producing an improved sugar beet, in particular a sugar beet which exhibits an increased content of sucrose, a reduced rate of sucrose breakdown during storage and an improved growth. The invention also relates to the use of at least two gene constructs for generating such a plant and to nucleotide sequences which are employed in this connection.

  • Nucleic acids coding for vacuolar invertases, vegetal cells and plants containing said nucleic acids and the use thereof
    Patent number: 7157280
    Abstract: The present invention relates to a nucleic acid molecule encoding a vacuolar invertase and its use for modifying the plant saccharose metabolism, in particular in the vacuole of the cell of a plant storage organ. The present invention also relates to a fragment of the nucleic acid molecule, a vector containing the nucleic acid molecule or a fragment thereof, as well as a host cell, in particular a plant cell that contains the nucleic acid molecule or a fragment thereof. The present invention also comprises a transgenic plant, methods for producing a transgenic plant, as well as methods for modifying the saccharose metabolism of a plant, in particular of a plant part.

  • Invertase inhibitor
    Patent number: 6384300
    Abstract: This invention relates to a nucleic acid that contains at least one nucleic acid sequence coding for a polypeptide, polypeptide being capable of reducing the enzymatic activity of an invertase; the polypeptide itself; and transgenic plants that contain this nucleic acid sequence. The invention further relates to methods of preparing such transgenic plants having reduced storage sucrose loss.
