Strengthening future food security through the application of unsustainable levels of inorganic nitrogen (N) fertilizers to crop fields may exacerbate environmental damage. Coordination of N-use efficiency (NUE) and plant growth is, therefore, crucial for sustainable agriculture. Auxin plays pivotal roles in developmental and signaling responses that affect NUE. Hence, a better understanding of these processes provides great potential to improve crop NUE. This review summarizes the effects of auxin on N-related and root developmental processes that either directly or indirectly affect NUE in the model plant Arabidopsis and major crop species to highlight the potential of fostering sustainable agricultural development in the future through modulating auxin-related processes.
通过在农田中应用不可持续水平的无机氮 (N) 肥料来加强未来的粮食安全，可能会加剧环境破坏。因此，协调氮利用效率 (NUE) 和植物生长对于可持续农业至关重要。生长素在影响 NUE 的发育和信号响应中发挥关键作用。因此，更好地理解这些过程为提高作物 NUE 提供了巨大的潜力。本综述总结了生长素对 N 相关和根系发育过程的影响，这些过程直接或间接地影响拟南芥和主要作物物种中的 NUE，突出了通过调节与生长素相关的过程来促进未来可持续农业发展的潜力。
