Improving nitrogen use efficiency (NUE) in rice is crucial for sustainable agriculture, yet remains a significant challenge due to its complex polygenic and environmental regulation. Although multiple NUE-associated genes have been identified, their intricate regulatory networks are poorly understood, especially under abiotic stresses such as drought, salinity, and extreme temperatures. This review systematically summarizes the genetic basis of NUE in rice, covering key genes involved in nitrogen uptake, translocation, assimilation, and remobilization. It further explores the crosstalk between nitrogen utilization and abiotic stress tolerance, highlighting integrative signaling nodes such as the dual nitrate/ABA receptor OsNRT1.1B. Finally, a comprehensive strategy is proposed to develop elite rice varieties with high NUE and multi-stress resilience, supporting the advancement of resource-efficient and climate-smart agriculture.
