  • Process for obtaining transgenic plants which have improved capacity for the uptake of nutrients and tolerance to toxic compounds which are present in the soil
    Publication number: 20050137386
    Abstract: The invention refers to a method for obtaining plants by genetic engineering techniques, with improved capacity to synthesize, to accumulate and to exude organic acids. More specifically it refers to the production of transgenic plants having an improved capacity to take up and excrete organic acids, providing them with a better uptake capacity of nutrients naturally present in the soil or added as fertilizers to the soil. These plants also have an increased capacity to tolerate the presence i the soil of certain toxic compounds such as aluminum.

  • Chimaeric gene coding for a transit peptide and a heterologous polypeptide
    Patent number: 6130366
    Abstract: Chimaeric DNA sequence which encodes: 1) a transmit peptide of a cytoplasmic precursor of a chloroplast protein or polypeptide of a plant and 2) a protein or polypeptide that is heterologous to the transit peptide. The chimaeric DNA sequence can be used as a vector for transforming a plant cell so that a chimaeric precursor of the heterologous protein or polypeptide is produced in the cytoplasm of the cell and the chimaeric precursor then transports the heterologous protein or polypeptide in vivo into a chloroplast of the cell.

  • Chimaeric gene coding for a transit peptide and a heterologous peptide
    Patent number: 5717084
    Abstract: A chimaeric DNA sequence comprising:a) a nucleic acid sequence coding for a chimaeric protein or polypeptide comprising in sequence:1) a transit peptide of a cytoplasmatic precursor of a chloroplast protein or polypeptide of a plant species, and,2) a protein or polypeptide of interest which is different from a mature chloroplast protein or polypeptide contained in a natural cytoplasmatic precursor thereof, and,b) a promoter upstream of the nucleic acid sequence recognized by polymerases endogenous to a plant, whereby the chimaeric DNA sequence can be expressed in cells of the plant under the control of the promoter and the protein or polypeptide of interest can be translocated in the chloroplasts of the cells of the plant.
