| 摘 要： | 氮素吸收代谢是所有生物生命活动的核心部分，因此，各种生物对氮的吸收与同化过程都有精细的调节。这种调节依赖于生物对体内氮素状况信号及体外（生长介质中）氮素信号的感受。过去几十年中，在细菌、真菌中已经对氮素营养信号有了较好的研究，而植物中则相对缓慢，但也有了一定的认识。本文重点比较细菌、真菌及植物中氮信号系统的组成，以期为进一步认识植物中的氮信号接受与转导系统提供启示。

| Abstract: | Due to its essential role in life process, nitrogen (N) uptake and metabolism is precisely regulated in all kinds of life organisms. The regulation of N uptake and metabolism depends on the sensing of internal and external N signals. In the past decades, much knowledge has been acquired in this aspect in bacteria and fungi. In plants, however, the progress is relatively slow and the knowledge about N signals is scare. In this review, the major component in N signal systems in bacteria, fungi and plants were compared so as to provide new insight for N signal research in pant systems. |
