参与土壤氮素循环的微生物功能基因多样性研究进展

土壤氮素循环是生物地球化学循环的重要组成部分, 不但影响着土壤生产力和可持续发展, 还影响着全球环境变化.土壤微生物在土壤氮循环中发挥着不可替代的作用, 参与了包括固氮作用、氨化作用、硝化作用和反硝化作用等重要生态过程.近十年中, 分子生物学技术的发展为从功能基因角度研究与土壤氮循环密切相关的微生物功能群结构、组成和丰度的变化提供了新的契机.本文综述了参与土壤氮循环的微生物功能基因多样性研究进展, 并展望了未来发展方向.

Advances in functional gene diversity of microorganism in relation to soil nitrogen cycling

Soil nitrogen cycling is an important part of biogeochemical cycling. Not only does it influence soil productivity and durative development, but also influences global environmental changes. Terrestrial microorganisms play a vital role in soil nitrogen cycling. They participate in important ecological processes such as nitrogen fixation, ammonification, nitrification and denitrification. With the development of molecular biological technology in recent decades, it is possible to study microbial functional community composition, structure and abundance in relation to soil nitrogen cycling from the point of functional gene. In this paper, advances in functional gene diversity in relation to soil nitrogen cycling are reviewed and future areas of improvement identified.
