Patents by Inventor Heiko Oltmanns

Heiko Oltmanns 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).

  • Backbone-free low transgene copy transgenic plants
    Patent number: 8334428
    Abstract: Methods and compositions reduce copy number of transgenes and minimizing vector backbone sequences in plant transformation. Agrobacterium strains with T-DNA integrated into the chromosomal DNA of the Agrobacterium reduce the copy number and vector backbone sequences. Chromosomal integration vectors to integrate T-DNA into a specific locus of Agrobacterium chromosome are disclosed.
    Type: Grant
    Filed: November 14, 2007
    Date of Patent: December 18, 2012
    Assignees: Purdue Research Foundation, Iowa State University Research Foundation, Inc.
    Inventors: Stanton B. Gelvin, Heiko Oltmanns, Lan Ying Lee, Bronwyn Frame, Kan Wang
  • Root-specific and xylem parenchyma-specific promoter
    Patent number: 7763774
    Abstract: The invention relates to a promoter that is provided with tissue-specific activity and is more active in xylem parenchyma cells of plant roots than it is in other cells of said plant. The inventive promoter allows transgenic plants to be produced with particular characteristics: (a) improved xylem charging and discharging processes in the root; (b) improved nitrogen supply; (c) reduced accumulation of harmful nitrogen in the root; (d) improved resistance to salt; (e) improved resistance to stress due to dry conditions; (f) improved tolerance to frost; (g) modified Na+/K+ concentration in the root; (h) greater resistance/tolerance to pathogens.
