  • Modified gene encoding glyphosate-tolerant 5-enolpruvyl-3-phosphoshikimate synthase
    Patent number: 6225114
    Abstract: DNA encoding glyphosate-tolerant 5-enolpyruvyl-3-phosphoshikimate (EPSP) synthases, plant genes encoding the glyphosate-tolerant enzymes, and plant transformation vectors containing the genes are disclosed. The DNA encodes glyphosate-tolerant EPSP synthases modified by substitution of an alanine residue for a glycine residue in a first conserved sequence found between positions 80 and 120, and a threonine residue for an alanine residue in a second conserved sequence found between positions 170 and 210 in the mature wild type EPSP synthase.
    Type: Grant
    Filed: February 1, 1999
    Date of Patent: May 1, 2001
    Assignee: Monsanto Company
    Inventors: David Alan Eichholtz, Charles Scott Gasser, Ganesh Murthy Kishore
  • Plant promoters
    Patent number: 6204373
    Abstract: The invention provides plant cyclophilin promoters that direct efficient expression of contiguous structural coding sequences in essentially all plant cells and plant organs of transgenic plants. In addition, chimeric genes containing the plant cyclophilin promoters of the invention and vectors comprising the plant cyclophilin promoters and chimeric genes of the invention are taught herein.
    Type: Grant

  • Glyphosate-tolerant 5-enolpyruvyl-3-phosphoshikimate synthases
    Patent number: 5866775
    Abstract: Glyphosate-tolerant 5-enolpyruvyl-3-phosphoshikimate (EPSP) synthases, DNA encoding glyphsate-tolerant EPSP synthases, plant genes encoding the glyphosate-tolerant enzymes, plant transformation vectors containing the genes, transformed plant cells and differentiated transformed plants containing the plant genes are disclosed. The glyphosate-tolerant EPSP synthases are prepared by substituting an alanine residue for a glycine residue in a first conserved sequence found between positions 80 and 120, and a threonine residue for an alanine residue in a second conserved sequence found between positions 170 and 210 in the mature wild type EPSP synthase.
