ENGINEERING PLANTS FOR EFFICIENT UPTAKE AND UTILIZATION OF UREA TO IMPROVE CROP PRODUCTION

摘要

The present disclosure provides polynucleotides and related polypeptides related to urea uptake. The disclosure provides genomic sequences for urea transporter, urease and glutamine synthetase genes. Urea transporters, urease and glutamine synthetase are responsible for controlling nitrogen utilization efficiency in plants. Urea transporter, urease or glutamine synthetase sequences are provided for improving grain yield and plant growth. The disclosure further provides recombinant expression cassettes, host cells and transgenic plants.
