PLANTS CONTAINING THE GDHA GENE AND METHODS OF USE THEREOF

摘要

Plants transformed with a gdhA gene and also with a gene used as a selectable marker provide a dual gene herbicide resistant and tolerance package. The transgenic plants and their progeny exhibit an expression cassette having transcription initiation and transcription termination regions functional in the plant cells, and a DNA sequence encoding the GDH enzyme. The expression cassette imparts a detectable level of herbicide resistance to the phosphinothricin class of herbicides. Transformed cells may further include a marker gene, such as the phosphinothricin acetyl transferase gene and/or the Bar gene. Plants having this expression cassette can be grown in an environment including a phosphinothricin class herbicide to control undesirable vegetation without significantly affecting crop growth.
