A Beginner’s Guide on Integrating *Omics Approaches to Study Marine Microbial Communities: Details and Discussions From Sample Collection to Bioinformatics Analysis

The variety of Earth’s organisms is manifold. However, it the small-scale marine community that makes world goes round. Microbial pro- and eukaryotic origin drive carbon supply nutrient cycling, thus are mediating primary productivity within largest ecosystem called ocean. But due to ocean’s great size large number biogeographically habitats, total microbial species can hardly be grabbed therefore their functional roles not fully described. recent advances in high-throughput sequencing technologies revolutionizing our understanding diversity, ecology evolution. Nowadays, research questions on differentiation solved with genomic approaches such as metabarcoding, while transcriptomics offers possibility assign gene functions even a single cell, e.g., single-cell transcriptomics. On other hand, diversified amount data, certainty data crisis currently evolving. Scientists forced broaden view bioinformatics resources for analysis storage from of, cloud services, ensure data’s exchangeability. Which why time now shifting toward solving problems rather than answering eco-evolutionary stated first place. This review intended provide exchange * omics key points discussions handling used decipher relevant diversity ecosystem.
