Xiaodan Yu 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).

  • Root-specific, stimulant inducible promoter and its use
    Patent number: 7560615
    Abstract: This invention relates to an isolated isoflavone synthase 1 (IFS1) promoter nucleic acid fragment. The invention also relates to the construction of chimeric genes comprising all or a portion of the IFS1 promoter directing the expression of transgenes, in sense or antisense orientation.
    Type: Grant
    Filed: November 1, 2005
    Date of Patent: July 14, 2009
    Assignees: EI, Pioneer Hi-Bred International
    Inventors: Joan T. Odell, Xiaodan Yu, Xu Hu, Ghihua Lu

  • Nucleic acid fragments encoding isoflavone synthase
    Publication number: 20060242735
    Abstract: This invention relates to an isolated nucleic acid sequence encoding isoflavone synthase. The invention also relates to the construction of chimeric sequences encoding all or a substantial portion of the enzymes, in sense or antisense orientation, wherein expression of the chimeric sequence results in production of altered levels of the enzyme in a transformed host cell.
    Type: Application

  • Method for altering the isoflavonoid profile in the plant parts of an isoflavonoid-producing plant
    Publication number: 20060218672
    Abstract: A method for altering the ratio of total daidzein to total genistein in isoflavonoid-producing plants by using a C1 myb transcription factor and an R-type myc transcription factor is described. Also described are plant comprising these transcription factors in their genome as well as isoflavonoid-containing products made from seeds of these plants. Such products have an increased ratio of total daidzein to total genistein when compared to the total daidzein to total genistein ratio of a control.
