Abstract

The invention is drawn to plant cell transformation with a nucleic acid construct comprising a prokaryotic ammonium-specific asparagine synthetase, type A, coding sequence, operably linked to a chloroplast transit peptide-encoding sequence, wherein said plant cells also contain a nucleic acid construct comprising a chloroplastic glutamine synthetase coding sequence in antisense orientation. Plant cells containing both nucleic acid constructs, and plants regenerated therefrom, exhibit improved growth characteristics.
