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.

提高作物的氮素利用效率（NUE）是实现可持续植物农业实践的必要条件，可最大限度地提高生产力，同时最大限度地减少氮肥依赖性污染。目前高投入的单一栽培植物生产系统的NUE很差，可能导致当地和全球的氮污染结果。 改善植物如何管理氮的吸收将提高NUE，并有助于支持澳大利亚的植物农业。该项目将研究重新设计硝酸盐运输活动的新技术。该项目还将研究氮吸收与改善植物生长所需的根系发育之间的生物化学和分子联系。
