ENHANCED NITRATE UPTAKE AND NITRATE TRANSLOCATION BY OVER- EXPRESSING MAIZE FUNCTIONAL LOW-AFFINITY NITRATE TRANSPORTERS IN TRANSGENIC MAIZE

摘要

Methods for modulating plants using optimized nitrate transporter constructs are disclosed. Also disclosed are nucleotide sequences, constructs, vectors, and modified plant cells, as well as transgenic plants displaying increased seed and/or biomass yield, improved tolerance to abiotic stress such as drought or high plant density, improved nitrogen utilization efficiency, increased ear tissue growth or kernel number.
