Methane is one of the most important greenhouse gases on Earth and holds an important
place in the global carbon cycle. Archaea are the only organisms that use methanogenesis …

Methyl-based methanogenesis is one of three broad categories of archaeal anaerobic
methanogenesis, including both the methyl dismutation (methylotrophic) pathway and the …

Recent discoveries of methyl-coenzyme M reductase–encoding genes (mcr) in uncultured
archaea beyond traditional euryarchaeotal methanogens have reshaped our view of …

Alkanes are saturated apolar hydrocarbons that range from their simplest form, methane, to
high-molecular-weight compounds. Although alkanes were once considered biologically …

Bathyarchaeia, as one of the most abundant microorganisms on Earth, play vital roles in the
global carbon cycle. However, our understanding of their origin, evolution, and ecological …

Anaerobic methane metabolism is among the hallmarks of Archaea, originating very early in
their evolution. Here, we show that the ancestor of methane metabolizers was an autotrophic …

Methanogenic and methanotrophic archaea produce and consume the greenhouse gas
methane, respectively, using the reversible enzyme methyl-coenzyme M reductase (Mcr) …

Methane produced by methanogenic archaea has an important influence on Earth's
changing climate. Methanogenic archaea are phylogenetically diverse and widespread in …

Tibetan pigs (TPs) can adapt to the extreme environments in the Tibetan plateau implicated
by their self-genome signals, but little is known about roles of the gut microbiota in the host …

Hadarchaeota inhabit subsurface and hydrothermally heated environments, but previous to
this study, they had not been cultured. Based on metagenome-assembled genomes, most …
