Edgar Benjamin Cahoon 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).

  • Phospholipid:diacylglycerol acyltransferases
    Publication number: 20030200563
    Abstract: This invention relates to an isolated nucleic acid fragment encoding an acyltransferase, more specifically a phospholipid:diacylglycerol acyltransferase. The invention also relates to the construction of a recombinant DNA construct encoding all or a portion of the phospholipid:diacylglycerol acyltransferase, in sense or antisense orientation, wherein expression of the recombinant DNA construct results in production of altered levels of the phospholipid:diacylglycerol acyltransferase in a transformed host cell.

  • Method for the production of calendic acid, a fatty acid containing delta-8,10,12 conjugated double bonds and related fatty acids having a modification at the delta-9 position
    Patent number: 6593514
    Abstract: The preparation and use of nucleic acid fragments encoding plant fatty acid modifying enzymes associated with modification of the delta-9 position of fatty acids, in particular, formation of conjugated double bonds are disclosed. Chimeric genes incorporating such nucleic acid fragments and suitable regulatory sequences can be used to create transgenic plants having altered lipid profiles. The preparation and use of nucleic acid fragments encoding plant fatty acid modifying enzymes associated with formation of a trans delta-12 double bond also are disclosed. Chimeric genes incorporating such nucleic acid fragments and suitable regulatory sequences can be used to create transgenic plants having altered lipid profiles.

    Assignee: E. I. du Pont de Nemours and Company
    Inventors: Edgar Benjamin Cahoon, William Dean Hitz, Kevin G. Ripp
  • Genes for plant fatty acid modifying enzymes associated with conjugated double bond formation
    Publication number: 20030126640
    Abstract: The preparation and use of nucleic acid fragments encoding plant fatty acid modifying enzymes associated with conjugated double bond formation or functionally equivalent subfragments thereof are disclosed. Chimeric genes incorporating such nucleic acid fragments or functionally equivalent subfragments thereof or complement thereof and suitable regulatory sequences can be used to create transgenic plants having altered lipid profiles.
