Compared to bacteria, our knowledge of archaeal biology is limited. Historically,
microbiologists have mostly relied on culturing and single-gene diversity surveys to …

Despite the relevance of submarine groundwater discharge (SGD) for ocean
biogeochemistry, the microbial dimension of SGD remains poorly understood. SGD can …

CRISPR–Cas systems defend prokaryotic cells from invasive DNA of viruses, plasmids and
other mobile genetic elements. Here, we show using metagenomics, metatranscriptomics …

The recently discovered DPANN archaea are a potentially deep-branching, monophyletic
radiation of organisms with small cells and genomes. However, the monophyly and early …

In hypersaline environments, Nanohaloarchaeota (Diapherotrites, Parvarchaeota,
Aenigmarchaeota, Nanoarchaeota, Nanohaloarchaeota [DPANN] superphylum) are thought …

DPANN is a widespread and diverse group of archaea characterized by their small size,
reduced genome, limited metabolic pathways, and symbiotic existence. Known DPANN …

Recent discoveries suggest that the candidate superphyla Patescibacteria and DPANN
constitute a large fraction of the phylogenetic diversity of Bacteria and Archaea. Their small …

We here present annotated lists of names of Candidatus taxa of prokaryotes with ranks
between subspecies and class, proposed between the mid-1990s, when the provisional …

The terrestrial subsurface hosts microbial communities that, collectively, are predicted to
comprise as many microbial cells as global surface soils. Although initially thought to be …

Hydrothermally active submarine volcanoes are mineral-rich biological oases contributing
significantly to chemical fluxes in the deep sea, yet little is known about the microbial …
