Introducing a new class in the archaea, Theionarchaea, and several other uncultured lineages

In addition to Theionarchaea, this new paper that appears in ISME Journal also details a variety of archaeal genomes there were obtained from the White Oak River Estuary in North Carolina.  This digram summarizes the ecological roles we have inferred from these genomes. This is important because NONE of these lineages have been grown in a laboratory, so having their genomes has significantly advanced our understanding of what they do in nature.

Genomic reconstruction of multiple lineages of uncultured benthic archaea suggests distinct biogeochemical roles and ecological niches
