宏基因组方法揭示草地土壤微生物群落响应全球变化

Metagenomics reveal responses of soil microbial community in grassland to global changes

草地在生物圈中发挥着重要的生态服务功能,而草地土壤微生物又是维持生态系统功能和稳定的关键要素之一。过去十几年间,宏基因组方法的进步为微生物群落分析提供了有力的工具。本文综述了宏基因组方法应用于草地土壤微生物群落响应全球变化的最新研究进展,特别是针对气候变化、大气组成变化、土地利用方式改变和外来物种入侵等条件下微生物群落的响应规律和反馈机制的研究。这些研究对于我们认识和了解微生物群落的生态功能十分重要,同时也对维持地球生态系统平衡具有积极的意义。最后,我们对未来应用宏基因组方法研究草地微生物群落进行了展望。

Grasslands play significant ecological roles in the biosphere.Soil microorganisms are a key factor in maintaining the function and stability of grasslands.Over the past decade,metagenomic technologies have provided new tools for analyzing microbial communities in various ecosystems.Here,we summarized the applications of metagenomics in grasslands.The latest progresses in the responses of soil microbial community to global change,especially climate change,atmospheric composition change,land use change,and exotic species invasion,are included.These studies are of great importance for fully improving our understanding of the ecological functions of soil microbial community in grasslands,and their significance in maintaining the balance of biosphere.Finally,we provide some prospective on the application of metagenomic tools in studying soil microbial communities in grasslands.
