Patents by Inventor Jeffrey E. Brotherton

Jeffrey E. Brotherton 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).

  • Nucleotide sequences encoding anthranilate synthase
    Patent number: 6563025
    Abstract: A 5-methyltryptophan resistant Nicotiana anthranilate synthase genes are disclosed, in particular the ASA2 gene of Nicotiana tabacum. Constructs containing the genes are also disclosed. This genes are useful for transforming plant cells and producing transformed plants and progenies which, compared to untransformed plant cells and plants, are more resistant to tryptophan analogs and/or produce increased levels of tryptophan. The transformed seeds are also disclosed. The genes are also useful as selectable markers. The amino acid sequence of ASA2, purified ASA2, and recombinant ASA2 are also disclosed.
    Type: Grant
    Filed: March 8, 1999
    Date of Patent: May 13, 2003
    Assignee: Board of Trustees of the University of Illinois
    Inventors: Hee-Sook Song, Jeffrey E. Brotherton, Jack M. Widholm
  • For selectable markers and promoters for plant tissue culture transformation
    Patent number: 5965727
    Abstract: A selectable marker, the ASA2 gene of Nicotiana tabacum, is provided for transforming plant cells. The ASA2 promoter sequence is also provided which is capable of directing tissue culture specific transcription of a downstream structural gene. Also disclosed are truncated forms of the ASA2 promoter which are capable of directing high level constitutive transcription of downstream structural genes. Constructs containing the above genes and promoters are also disclosed.
