摘要

摘要: 氮是植物生长过程中必需的矿质元素，对植物生长发育具有重要影响。外施氮肥可以促进植物生长，但氮肥的滥用会导致水土污染、臭氧层破坏和农业生产成本增加等问题。为提高氮素利用率，植物在演变过程中产生了一系列吸收、转运和同化氮素的分子机制。本文综述了植物对NO₃⁻-N、NH₄⁺-N和有机态氮的分子调控机制，并阐明了转录因子和miRNA在氮素响应中的作用，旨在为提高氮素利用效率和农业生产力以及培育新品种提供参考。

Abstract: Nitrogen is one of the essential elements for plant growth and development. External application of nitrogen promotes plant growth, but excessive fertilization can induce a host of problems on soil and water pollution, ozone layer depletion, and agricultural production cost escalation. In nature, to efficiently utilize the resource, plants have evolved mechanisms that regulate the absorption of the critical nutrient transported from the land. This article reviews such fundamental natural functions, in addition to the processes of NO₃⁻N, NH₄⁺-N, and organic nitrogen assimilations as well as the roles of transcription factors and miRNAs in response to nitrogen fertilization. Based on the information, improvements on the nitrogen use efficiency of plants, agriculture productivity, and breeding and cultivation of new crop varieties could be studied and realized.
