Systems Microbiology aims to serve as a platform for the exchange of ideas between microbiologists with expertise in Metagenomics, Metatranscriptomics, Metaproteomics, Metametabolomics, Single Cell Genomics, Functional Genomics, Synthetic Microbiology, Bioinformatics and Computational Microbiology. Microorganisms are ideal for systems biology studies because they are easy to manipulate and have crucial roles in the biosphere and human health. This series examines some of the latest developments in this fast-moving field. It focuses on Bacteria and Archaea; eukaryotic microorganisms will only be considered in rare cases. The journal perceives a broad understanding of microbial diversity and encourages.
