Abstract: The global nitrogen cycle is one of the most important biogeochemical cycles on earth,which is predominantly driven by a large number of microorganisms in various ecosystems. The application of metagenomics to reveal the total amount and diversity of functional microbial communities involved in nitrogen cycle,is one of the hotspots of environmental microbiology in recent years. In this paper,we briefly summarized the recent discovery on the functional microorganisms involved in nitrogen cycle. In addition,we focused on the selection of functional genes that could indicate certain nitrogen biological processes(including nitrogen fixation,nitrification,denitrification,anammox,assimilatory/dissimilatory nitrogen reduction,ammonification and assimilation),and also highlighted the applications of these functional genes to detect the distribution of functional microbial communities in natural environments. Finally,we pointed out the importance of molecular detection techniques and data analysis platforms for future functional microbiological studies.

Key words: metagenomics, functional genes, nitrogen cycle, molecular detection techniques, functional microbes
