Improved nitrogen use efficiency (NUE) in crop plants is required to achieve sustainable plant agriculture practices that maximise productivity while minimising nitrogen fertiliser-dependent pollution. Current high-input monoculture plant production systems suffer from poor NUE and can contribute to local and global nitrogen pollution outcomes. Improving how plants manage their nitrogen uptake will improve NUE and help support Australian plant agriculture. This project will investigate novel technologies that re-engineer nitrate transport activity. The project will also investigate the biochemical and molecular links between nitrogen uptake on root development required for improved plant growth.

需要提高农作物植物中的氮利用效率（NUE），以实现可持续的植物农业实践，从而最大程度地提高生产力，同时最大程度地减少氮肥依赖性污染。当前的高输入单栽培植物生产系统遭受较差的状态，可以促进局部和全球氮污染结果。 改善植物如何管理氮的摄取将改善nue并帮助支持澳大利亚植物农业。该项目将研究重新设计硝酸盐运输活性的新技术。该项目还将研究氮对改善植物生长所需的根源发育的氮摄取之间的生化和分子联系。
