MANIPULATION OF GLUTAMINE SYNTHETASES (GS) TO IMPROVE NITROGEN USE EFFICIENCY AND GRAIN YIELD IN HIGHER PLANTS

摘要

The present invention provides polynucleotides and related polypeptides of the protein GS. The invention provides genomic sequence for the GS gene. GS is responsible for controlling nitrogen utilization efficiency in plants. Glutamine synthase sequences are provided for improving grain yield and plant growth. The invention further provides recombinant expression cassettes, host cells and transgenic plants.
