硝酸盐（NO3–）不仅是植物生长必需的营养素，也是植物生长的重要信号分子。农作物氮素利用效率（NUE）低下正在造成日益严重的环境和生态问题。了解作物中 NO3- 调节的分子机制对于改善农业 NUE 至关重要。在过去的几年中，人们在了解作物中 NO3- 信号传导的调控方面取得了重大进展，并且一些关键的 NO3- 信号因子已被证明在 NO3- 利用中发挥着重要作用。然而，尚未有详细的评论总结这些进展。在这里，我们主要关注作物NO3-信号传导的最新进展，包括短期信号传导、长期信号传导以及环境因素的影响。我们还回顾了参与 NO3- 信号传导的关键基因对作物 NUE 的调节。该综述为进一步研究作物中NO3-信号传导提供了有用的信息，并为选育高NUE作物新品种提供了理论依据，对可持续农业具有重要意义。阐明作物硝酸盐信号的调控机制对于提高NUE非常重要。该综述总结了调节作物硝酸盐信号传导和影响NUE的关键基因的研究进展，为作物硝酸盐调控研究提供重要信息，并为提高NUE提供理论基础。
Nitrate (NO3–) is not only an essential nutrient but also an important signaling molecule for plant growth. Low nitrogen use efficiency (NUE) of crops is causing increasingly serious environmental and ecological problems. Understanding the molecular mechanisms of NO3– regulation in crops is crucial for NUE improvement in agriculture. During the last several years, significant progress has been made in understanding the regulation of NO3– signaling in crops, and some key NO3– signaling factors have been shown to play important roles in NO3– utilization. However, no detailed reviews have yet summarized these advances. Here, we focus mainly on recent advances in crop NO3– signaling, including short-term signaling, long-term signaling, and the impact of environmental factors. We also review the regulation of crop NUE by crucial genes involved in NO3– signaling. This review provides useful information for further research on NO3– signaling in crops and a theoretical basis for breeding new crop varieties with high NUE, which has great significance for sustainable agriculture. Elucidating the regulatory mechanisms of crop nitrate signaling is very important for improving NUE. This review summarizes advances in characterizing the crucial genes that modulate crop nitrate signaling and affect NUE, providing important information for research on crop nitrate regulation and a theoretical basis for improving NUE.
