Abstract:
1. A method for increasing or decreasing nitrogen metabolism in plant cells, said method comprising the steps of transforming a plant cell with a recombinant polynucleotide comprising a polynucleotide sequence encoding a polypeptide having glutamate dehydrogenase activity, and culturing said cell whereby descendant cells are produced which comprise said polynucleotide sequence and express said polynucleotide sequence, whereby nitrogen metabolism is increased or decreased as compared to nitrogen metabolism of untransformed plant cells; wherein said polynucleotide sequence is operably linked to a polynucleotide encoding a chloroplast transit peptide, and wherein the chloroplast transit peptide comprises SEQ ID NO: 5 or SEQ ID NO: 6, or a fragment thereof of sufficient length to exhibit chloroplast transit activity.
