Potato plays a key role in global food and nutritional security. Potato is an N fertiliser-responsive crop, producing high tuber yields. However, excessive use of N can result in environmental damage and high production costs, hence improving nitrogen use efficiency (NUE) of potato plants is one of the sustainable options to address these issues and increase yield. Advanced efforts have been undertaken to improve NUE in other plants like Arabidopsis, rice, wheat and maize through molecular and physiological approaches. Conversely, in potato, NUE studies have predominantly focussed on agronomy or soil management, except for a few researchers who have measured gene expression and proteins relevant to N uptake or metabolism. The focus of this review is to adapt knowledge gained from other plants to inform investigation of N metabolism and associated traits in potato with the aim of improving potato NUE using integrated genomics, physiology and breeding methods.
马铃薯在全球粮食和营养安全中发挥着关键作用。马铃薯是一种对氮肥有反应的作物，块茎产量很高。然而，过量使用氮肥会导致环境破坏和生产成本增加，因此提高马铃薯植株的氮素利用效率（NUE）是解决这些问题并提高产量的可持续选择之一。人们已经通过分子和生理方法在拟南芥、水稻、小麦和玉米等其他植物上进行了提高氮素利用效率的深入研究。相反，在马铃薯方面，氮素利用效率的研究主要集中在农艺学或土壤管理上，只有少数研究人员测量了与氮吸收或代谢相关的基因表达和蛋白质。本综述的重点是借鉴其他植物的研究成果，为马铃薯氮代谢及相关性状的研究提供参考，以期通过整合基因组学、生理学和育种方法提高马铃薯的氮素利用效率。
