  • Method for modifying production of fruit ripening enzyme
    Patent number: 6271033
    Abstract: Process for the inhibition of the production of a gene product in a plant cell which comprises generating in the cell while the gene product is being expressed mRNA from recombinant DNA coding for part only of the gene product: also constructs for use in the process, and cells and plants that carry out the process. Specifically applicable to control of fruit ripening, in particular in tomatoes.
    Type: Grant
    Filed: December 7, 1993
    Date of Patent: August 7, 2001
    Assignee: Zeneca Limited
    Inventors: Ian G. Bridges, Donald Grierson, Wolfgang W. Schuch
  • Plant-derived glutathione-S-transferase isoform II promoter
    Patent number: 5589614
    Abstract: The chemically-inducible 27 kD subunit of the enzyme glutathione-S-transferase, isoform II (GST-II-27) and sequences encoding it are provided. In particular, a genomic DNA sequence encoding the gene promoter for the GST-II-27 subunit is provided. When linked to an exogenous gene and introduced into a plant by transformation, the GST-II-27 promoter provides a means for the external regulation of expression of that exogenous gene. Transformation with DNA encoding glutathione-S-transferase polypeptides produces herbicide resistance transgenic plants.
    Type: Grant
    Filed: May 23, 1994
    Date of Patent: December 31, 1996
    Assignee: Zeneca Limited
    Inventors: Ian G. Bridges, Simon W. J. Bright, Andrew J. Greenland, David C. Holt, Ian Jepson, Wolfgang W. Schuch
  • Male flower specific gene sequences
    Patent number: 5571904
    Abstract: Three similar gene sequences are provided, the sequences being shown in the drawings, which are recovered from male flower parts of maize, specifically anther tissue. When one or more of these sequences are included in a gene construct, expression of an encoded protein is restricted to male parts of the plant. The sequences have utility in any application where expression in male flower parts is indicated, a specific application is in the control of expression of a disrupter protein which imparts male sterility when incorporated in a plant genome.
    Type: Grant
    Filed: June 27, 1994
    Date of Patent: November 5, 1996
    Assignee: Zeneca Limited
    Inventors: Ian G. Bridges, Simon W. J. Bright, Andrew J. Greenland, Wolfgang W. Schuch
  • Dicot plants containing an antisense polygalacturonase gene segment
    Patent number: 5457281
    Abstract: Recombinant DNA comprises promoter and terminator base sequences respectively upstream and downstream of an inverted base sequence complementary to a substantial sequence of bases in polygalacturonase mRNA. The antisense mRNA produced thereby delays softening of fruit, in particular tomatoes.
    Type: Grant
    Filed: September 29, 1989
    Date of Patent: October 10, 1995
    Assignee: Zeneca Limited
    Inventors: Ian G. Bridges, Wolfgang W. Schuch, Donald Grierson
  • DNA constructs containing segments from tomato polygalacturonase and pectin esterase genes
    Patent number: 5413937

Specifically applicable to control of fruit ripening, in particular in tomatoes.

  • Tomatoes with reduced expression of polygalacturonase
    Patent number: 5387757
    Abstract: Fruit, especially tomatoes, having lowered expression of fruit-softening enzymes caused by antisense gene expression, and seeds therefrom.
    Type: Grant
    Filed: April 1, 1993
    Date of Patent: February 7, 1995
    Assignee: Zeneca Limited
    Inventors: Ian G. Bridges, Wolfgang W. Schuch, Donald Grierson
  • DNA, constructs, cells and plants derived therefrom
    Patent number: 5296376
