Nitrogen (N) is an essential macronutrient required for plant growth and crop production. However, N in soil is usually insufficient for plant growth. Thus, chemical N fertilizer has been extensively used to increase crop production. Due to negative effects of N rich fertilizer on the environment, improving N usage has been a major issue in the field of plant science to achieve sustainable production of crops. For that reason, many efforts have been made to elucidate how plants regulate N uptake and utilization according to their surrounding habitat over the last 30 years. Here, we provide recent advances focusing on regulation of N uptake, allocation of N by N transporting system, and signaling pathway controlling N responses in plants.

氮（N）是植物生长和作物生产所必需的大量营养素。然而，土壤中的 N 通常不足以满足植物生长的需求。因此，化学氮肥被广泛用于提高作物产量。由于富 N 肥料对环境的负面影响，提高 N 的利用率一直是植物科学领域的一个主要问题，以实现作物的可持续生产。为此，在过去的 30 年中，人们做出了许多努力来阐明植物如何根据周围环境调节 N 的吸收和利用。在这里，我们提供了最新的研究进展，重点介绍了植物中 N 吸收的调节、N 运输系统的 N 分配以及控制 N 响应的信号通路。[BMB 报告 2023;56(2):56-64]。
