  • Methods and a maize acetyl CoA carboxylase gene for altering the oil content of plants
    Patent number: 6268550
    Abstract: The present invention provides the complete cDNA sequence of maize acetyl CoA carboxylase and methods for altering the oil content of plants by introducing and expressing a plant acetyl CoA carboxylase gene in plant cells. The method of altering the oil content in a plant includes the steps of introducing an expression cassette into plant cells and expressing the acetyl CoA carboxylase gene in an amount effective to alter the oil content of the cells.
    Type: Grant
    Filed: August 12, 1996
    Date of Patent: July 31, 2001
    Assignees: Regents of the University of Minnesota, The United States of America
    Inventors: Burle G. Gengenbach, David A. Somers, Donald L. Wyse, John W. Gronwald, Margaret A. Egli, Sheila M. Lutz
  • Transgenic plants expressing maize acetyl COA carboxylase gene and method of altering oil content
    Patent number: 6222099
    Abstract: The present invention provides a complete cDNA sequence and partial DNA sequences encoding maize acetyl CoA carboxylase and methods for altering the oil content of plants by introducing and expressing a maize acetyl CoA carboxylase gene in plant cells.
    Type: Grant
    Filed: April 13, 1998
    Date of Patent: April 24, 2001
    Assignees: Regents of the University of Minnesota, The United States of America
    Inventors: Burle G. Gengenbach, David A. Somers, Donald L. Wyse, John W. Gronwald, Margaret A. Egli, Sheila M. Lutz
  • Methods for expressing a maize acetyl CoA carboxylase gene in host cells and encoded protein produced thereby
    Patent number: 6146867
    Abstract: The present invention provides the complete cDNA sequence of maize acetyl CoA carboxylase and a method introducing and expressing a plant acetyl CoA carboxylase gene in plant cells. The method includes the steps of introducing an expression cassette encoding a plant acetyl CoA carboxylase or an antisense DNA sequence complementary to the sequence for a plant acetyl CoA carboxylase gene operably linked to a promoter functional in plant cells, into the cells of a plant tissue and expressing the plant acetyl CoA carboxylase gene. The expression cassette can also be introduced into other host cells to increase yield of a plant acetyl CoA carboxylase crystallized enzyme.

  • Methods and an acetyl CoA carboxylase gene for conferring herbicide tolerance and an alteration in oil content of plants
    Patent number: 6069298
    Abstract: The present invention provides the complete cDNA sequence of maize acetyl CoA carboxylase and methods for conferring herbicide tolerance and/or altering the oil content of plants by introducing and expressing a plant acetyl CoA carboxylase gene in plant cells. The method of imparting herbicide tolerance to a plant includes the steps of introducing an expression cassette encoding a plant acetyl CoA carboxylase or an antisense DNA sequence complementary to the sequence for a plant acetyl CoA carboxylase gene operably linked to a promoter functional in plant cells, into the cells of a plant tissue and expressing the plant acetyl CoA carboxylase gene in an amount effective to render the acetyl CoA carboxylase and/or plant cell substantially tolerant to the herbicides. The method of altering the oil content in a plant includes the steps of introducing an expression cassette into plant cells and expressing the acetyl CoA carboxylase gene in an amount effective to alter the oil content of the cells.
    Type: Grant
    Filed: April 5, 1995
    Date of Patent: May 30, 2000

    Inventors: Burle G. Gengenbach, David A. Somers, Donald L. Wyse, John W. Gronwald, Margaret A. Egli, Sheila M. Lutz
  • Method and an acetyl CoA carboxylase gene for conferring herbicide tolerance
    Patent number: 5498544
    Abstract: The present invention provides an expression cassette encoding a plant acetyl CoA carboxylase gene and methods for conferring herbicide tolerance and/or altering the oil content of plants by introducing and expressing a plant acetyl CoA carboxylase gene in plant cells. An expression cassette of the invention can comprise a gene coding a plant acetyl CoA carboxylase or a functional mutant thereof or an antisense DNA sequence complementary to the sequence for a plant acetyl CoA carboxylase gene combined with a promoter functional in a plant cell. The method of imparting herbicide tolerance to a plant includes the steps of introducing the expression cassette into the cells of a plant tissue and expressing the plant acetyl CoA carboxylase gene in an amount effective to render the acetyl CoA carboxylase and/or plant cell substantially tolerant to the herbicides.
