The conversion plant of plant gene, the plant conversion carrier that contains these genes, the transformed plant cells that contains these plant genes and differentiation of DNA, the coding glyphosate-tolerant enzyme of glyphosate-tolerant 5-enol pyruvoyl-3-phosphoric acid shikimic acid (EPSP) synthase, coding glyphosate-tolerant EPSP synthase is disclosed.Glyphosate-tolerant EPSP synthase is by being prepared by alanine residue displacement glycine residue in the conservative order between 80 and 120 on being present in sophisticated wild-type EPSP synthase.
