Zusammenfassung:	This invention relates to glyphosate-resistant transgenic plants and methods of making the same. In a preferred embodiment, a DNA fragment which comprises an EPSPS 5' regulatory sequence and a glyphosate-resistant EPSPS coding sequence is introduced into regenerable plant cells. The encoded EPSPS has a chloroplast transit peptide. The DNA fragment does not contain a non-EPSPS enhancer. Cells are selected for stable transformation, and the selected cells can be used to regenerate glyphosate-resistant transgenic plants. The DNA fragment used for transformation preferably comprises a modified plant genomic sequence, such as SEQ ID NO: 2, SEQ ID NO:4 or SEQ ID NO: 6. In one embodiment, two DNA fragments of this invention are stably transformed into a plant to confer glyphosate-resistance.
