摘要

Microorganisms play crucial roles in maintaining ecosystem stability. The last two decades have witnessed an upsurge instudies on marine microbial community composition using high-throughput sequencing methods. Extensive mining ofthe compositional data has provided exciting new insights into marine microbial ecology from a number of perspectives.Both deterministic and stochastic processes contribute to microbial community assembly but their relative importance instructuring subcommunities, that are categorized by traits such as abundance, functional type and activity, differs. Throughcorrelation-based network analysis, significant progress has been made in unraveling microbial co-occurrence patterns anddynamics in response to environmental changes. Prediction of ecosystem functioning, based on microbial data, is receivingincreasing attention, as closely related microbes often share similar ecological traits and microbial diversity often exhibitssignificant correlations to ecosystem functioning. The ecosystem functioning is likely executed not by the whole community,but rather by an active fraction of a community, which can be inferred from the marker gene transcription level of communitymembers. Furthermore, the huge amount of microbial community data has significantly expanded the tree of lifeand illuminated microbial phylogenetic divergence and evolutionary history. This review summarizes important findingsin microbial assembly, interaction, functioning, activity and diversification, highlighting the interacting roles of differentaspects, derived from community compositional data.
