  • 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
  • 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.
