Metagenomics unravel distinct taxonomic and functional diversities between terrestrial and aquatic biomes.

ABSTRACT: Microbes in terrestrial and aquatic ecosystems play crucial roles in driving ecosystem functions, but currently, there is a lack of comparison regarding their taxonomic and functional diversities. Here, we conducted a global analysis to investigate the disparities in microbial taxonomy and microbial-mediated biogeochemical cycles between terrestrial and aquatic ecosystems. Results showed a higher relative abundance of bacteria, especially Actinobacteria and Acidobacteria, in soil than water metagenomes, leading to a greater proportion of genes related to membrane transport, regulatory, and cellular signaling. Moreover, there was a higher abundance of genes associated with carbohydrate, sulfur, and potassium metabolisms in the soil, while those involved in nitrogen and iron metabolisms were
