Distribution of Asgardarchaeota based on the recovery of MAGs from a wide variety of habitats. The ecological distribution of the Asgardarchaeota genomes across 12 environments, including genomes added by this study (purple star) and the total number of MAGs (yellow circle). The bar chart shows the number of MAGs from each lineage by environment, indicating lineages found only in a single environment (Atabeyarchaeia; teal triangle), circular complete genomes (black circle), and MAGs with known associated viruses or proviruses (blue phage). We note the novel class, Ranarchaeia, and recently described Asgardarchaeia in the legend with asterisks. Guaymas Basin is shown separately from the other bathypelagic-associated MAGs to showcase the increased genomic diversity from this site. -- biorxiv.org

Oxygen Metabolism In Descendants Of The Archaeal-Eukaryotic Ancestor

by Keith CowingJuly 8, 2024July 7, 2024

Asgard archaea were pivotal in the origin of complex cellular life. Hodarchaeales (Asgardarchaeota class Heimdallarchaeia) were recently shown to be the closest relatives of eukaryotes. However, limited sampling of these […]
