  • Publication number: 20060195940
    Abstract: The present invention provides plants with a modified taste, solids content and/or texture. The invention also provides methods of obtaining such plants via transformation with DNA constructs containing genes encoding enzymes capable of degrading plant polysaccharides and optionally additional genes encoding enzymes which are capable of further modifying the degradation products resulting from the first degradation step.

  • Patent number: 7033627
    Abstract: A method of catalyzing in vitro reactions using seeds containing enhanced amounts of enzymes is disclosed. The method involves adding transgenic, non-wild type seeds, preferably in a ground form, to a reaction mixture, especially a bakery process and allowing the enzymes in the seeds to increase the rate of reaction. By directly adding the seeds to the reaction mixture the method provides a solution to the expensive and problematic process of extracting and purifying the enzyme. Methods of treatment are also provided whereby a subject lacking a sufficient supply of an enzyme is administered the enzyme in the form of seeds containing enhanced amounts of the enzyme.

  • Patent number: 6022846
    Abstract: The present invention provides for the expression of phytase in transgenic plants or plant organs and methods for the production of such plants. DNA expression constructs are provided for the transformation of plants with a gene encoding phytase under the control of regulatory sequences which are capable of directing the expression of phytase. These regulatory sequences include sequences capable of directing transcription in plants, either constitutively, or stage and/or tissue specific, depending on the use of the plant or parts thereof. The transgenic plants and plant organs provided by the present invention may be applied to a variety of industrial processes either directly, e.g. in animal feeds or alternatively, the expressed phytase may be extracted and if desired, purified before application.

  • Patent number: 5925804
    Abstract: A nucleic acid having (i) a DNA molecule which, when expressed in a plant or plant cell, increases the trehalose content of the plant or plant cell, the DNA molecule encoding an E. coli trehalose phosphate synthase, and (ii) a plant expressible promoter operatively coupled to the DNA molecule. Also, a method for obtaining a plant with increased trehalose production by introducing into a recipient cell of a plant, a plant expressible gene which, when expressed in a plant or plant cell increases the trehalose content of the plant or plant cell. The plant expressible gene is an E. coli trehalose phosphate synthase gene which is operably linked to: a) a transcriptional initiation region that is functional in the plant, and b) a DNA molecule encoding a selectable marker gene that is functional in the plant. The method includes a step of regenerating a plant from the recipient cell under conditions that allow for selection for the presence of the selectable marker gene.

  • Patent number: 5763748
    Abstract: This invention provides for a method to produce excreted and correctly processed heterologous protein-material in a plant host. The method comprises the step of transforming a plant host using a recombinant polynucleotide, which comprises the DNA sequences encoding the fully processed heterologous protein material, directly preceded by a DNA sequence coding for a plant signal peptide, and regulatory sequences necessary for the plant host to express the heterologous gene construct, resulting in excretion of the heterologous protein from the cell and correct cleavage of the N-terminal signal peptide, so that the mature heterologous protein produced by the plant host is identical to the corresponding protein produced in its authentic host.
