Abstract: Plant nitrogen metabolism in corn and tobacco has been altered by transformation with a highly active assimilatory glutamate dehydrogenase gene. Plants containing the gdhA gene are resistant to phosphinothricin herbicides (PPT) which can include glufosinate herbicides. Additionally, these transformed plants evidence higher levels of tolerance to PPT when combined with another PPT resistant gene. This invention also includes the method of improving plant growth in a field of crops encoding for GDH due to a gdhA transgene.
