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.
