Title: A multi-omic future for microbiome studies

Microbes constitute about a third of the Earth’s biomass and play critical roles in sustaining life. While results from multiple sequence-based studies have illustrated the importance of microbial communities for human health and the environment, additional technological developments are still needed to gain more insight into their functions [1]. To date, the majority of sequencing studies have focused on the 16S rRNA gene as a phylogenetic marker. This approach has enabled exploration of microbial compositions in a range of sample types, while bypassing the need for cultivation. 16S rRNA gene sequencing has also enabled a vast majority of microorganisms never previously isolated in culture to be identified and placed into a phylogenetic context [2]. These technologies have been utilized to map the locations of microbes inhabiting various locations of the body [3]. Similarly, sequencing has been used to determine the identities and distributions of microorganisms inhabiting different ecosystems [4, 5], and efforts in single cell sequencing of the microbiome have helped fill in missing branches of the phylogenetic tree [6].
