- 低氮素利用效率对农田生态系统所造成的污染日益加重，如何提高作物的氮素利用效率已成为目前的一个研究热点。文章分析了植物体内硝酸盐转运体（Nitrate transporters,NRT）的分类、存在部位、生物学功能及调控机制，旨在阐明植物吸收、转运NO3-的生理机制，指出了利用分子生物学的手段是提高作物氮素利用效率的一个重要方向，这为今后通过基因工程的手段来提高氮素利用效率，减少环境污染提供了一定的理论依据。
- Abstract:
- Lower nitrogen use efficiency（NUE）caused the aggravation of the ecosystem pollution.How to improve the NUE has become a hot research goal.To clarify the physiological characteristics of absorption and transportation of NO3- by plants，the classification of the NRT and its presence organ，biology functions and regulatory mechanisms in plant was summarized in this paper and pointed out.There was an important way to improve the NUE of plant by the means of molecular biology.A theoretical basis for the future to improve NUE and reduce environmental pollution by methods of genetic engineering were provided.
