Abstract: Nitrogen use efficiency (NUE) is a pivotal indicator for achieving high wheat yields and sustainable resource utilization. This paper reviews recent research advances in the NUE of wheat, emphasizing genotypic variations, physiological mechanisms, molecular regulation, and agronomic management practices. Furthermore, this paper analyzes the critical regulatory nodes in nitrogen uptake, transport, assimilation, and redistribution, summarizes the current research bottlenecks, and makes an outlook on the future research directions. We then propose a strategy integrating emerging biotechnologies with precision agronomic management to enhance both wheat yields and NUE. This review aims to offer a theoretical framework for breeding nitrogen-efficient wheat cultivars and promoting the eco-friendly production of wheat.
