Patents by Inventor Wolfgang Schuch

Wolfgang Schuch has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Recombinant DNA containing pectin esterase gene segements
    Patent number: 5447867
    Abstract: Recombinant DNA comprises promoter and terminator base sequences respectively upstream and downstream of a base sequence corresponding to a substantial sequence of bases in pectin esterase mRNA. The mRNA produced thereby delays softening of fruit, in particular tomatoes.
    Type: Grant
    Filed: February 26, 1993
    Date of Patent: September 5, 1995
    Assignee: Imperial Chemical Industries PLC
    Inventors: Ian Bridges, Wolfgang Schuch, Donald Grierson
  • DNA constructs containing segments from tomato polygalacturonase and pectin esterase genes
    Patent number: 5413937
    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.
