Qing Gu 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).

  • Method of decreasing seed size in a plant
    Patent number: 6541683
    Abstract: The present invention provides a non-naturally occurring seed plant that is characterized by producing seeds of increased size due to ectopic expression of a nucleic acid molecule encoding an AGL8-related gene product. The AGL8-related gene product can have, for example, substantially the amino acid sequence of an AGL8 ortholog such as Arabidopsis AGL8 (SEQ ID NO:2). The present invention further provides a non-naturally occurring seed plant that is characterized by producing fruit of increased size due to ectopic expression of a nucleic acid molecule encoding an AGL8-family gene product. The AGL8-family gene product can have substantially the amino acid sequence of an AGL8 ortholog, for example, the amino acid sequence of Arabidopsis AGL8 (SEQ ID NO:2). Related methods and kits also are provided.
    Type: Grant
    Filed: November 7, 2000
    Date of Patent: April 1, 2003
    Assignees: The Regents of the University of California, Cold Spring Harbor Laboratory
    Inventors: Martin F. Yanofsky, Robert Martienssen, Cristina Ferrandiz, Qing Gu

  • Oxygen regulatable gene expression
    Patent number: 4970147
    Abstract: The invention discloses that, in the presence of NifA and NtrA, the expression of a desired DNA molecule which has been operably linked to an ntrA-RNA polymerase and NifA dependent promoter can be regulated by regulating the oxygen level of the culture medium. The invention relates to vectors which may be used in accordance with this discovery, and to methods for using such vectors.
