Deyu Xie 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).

  • Patent number: 7622638
    Abstract: The invention provides method and compositions for the modulation of condensed tannin production in plants. The methods of the invention allow creation of plants having novel phenotypes. Increased expression of condensed tannins in plants may be used to increase the nutritional value of food plants for both human and animal consumption. Increased condensed tannin content also reduces the potential for bloat in animals fed certain forage plants low in condensed tannin content. The invention may also be used to modify plant pigmentation.
    Type: Grant

    Date of Patent: November 24, 2009

  • Patent number: 7368631
    Abstract: The present invention is directed to a method of Acacia mangium regeneration through organogenesis and a method of genetic transformation of Acacia mangium. The method of regeneration comprises inducing callus from different parts of seedlings and vegetatively micropropagated plantlets as explants; adventitious bud induction followed by pinnate leaf and bud elongation and eventually, elongated shoots were induced to root. Based on the regeneration system, a marker gene GUS under cauliflower mosaic virus promoter was introduced to Acacia mangium via Agrobacterium infection. GUS staining in the regenerated plants and Southern blot hybridization prove the incorporation of the foreign gene into the host genome and expression of the foreign gene.
