摘 要: 生物固氮在自然界生态系统氮循环中发挥重要作用,也在农林业生产中具有重大的潜在应用价值。固氮是一个多基因调节,多种相关分子参与的过程。为了阐明固氮中各基因的作用以及相关分子过程,科学家进行了长期深入的研究,以期最终能够使现有不能固氮的作物获得固氮能力。对近几年固氮中相关分子研究进行总结,希望获得对固氮分子机理的及固氮基因转移研究进展的总体认识。

Abstract: Biological nitrogen fixation not only plays an important role in the nitrogen cycle, but also has significant potential value in agroforestry production. Nitrogen fixation is a process of multiple-gene regulation and involves a variety of related molecules. In order to clarify the role of each gene and related molecular processes in nitrogen fixation, make non-nitrogen fixing crops getting the ability of nitrogen fixation, scientists had many long-term studies. This review is intended to summarize the molecular mechanism of nitrogen fixation, to help obtaining the overall understanding in the molecular mechanism of nitrogen fixation and nitrogen fixation gene transformation.
Key words: nitrogen fixation; molecular mechanism; nitrogen fixation transformation
