These Away Teams Are Building The Largest Knowledge Graph Of Life On Earth
Editor’s note: As we search for life on other worlds via orbital and surface surveys, it is useful to use Earth and its diverse biota on land, sea, and air, […]
![Maximum likelihood phylogenetic tree of [NiFe]-hydrogenase gene sequences obtained from our MAGs (n = 2433), with reference sequences obtained from the HydB and previous phylogenetic analysis. Branches and reference gene labels are colored according to the group of [NiFe]-hydrogenase. Bootstrap values >90% are depicted as filled circles on branches, with size reflecting value, and 1000 ultrafast bootstrap iterations applied. The phyla of the originating MAGs assembled in this study are displayed in a color-coded outer ring. In cases where RuBisCO large subunit gene/s co-occurred within these genomes, the proportion of forms present is indicated by external pie charts. -- biorxiv.org](https://i0.wp.com/astrobiology.com/wp-content/uploads/2023/08/metagenomics1.png?resize=1200%2C718&ssl=1)

Using Metagenomics To Better Understand Hydrothermal Communities
Researchers supported in part by the NASA Astrobiology Program have used genome-resolved metagenotics and metatranscriptomics to better understand microbial communities in the subseafloor near hydrothermal vents. These techniques provide details […]
