New isolates from eukaryote's closest archaeal relative: ‘Hodarchaeales’!! Syntrophic microaerotolerant peptide-degrading anaerobic archaea w/ simple cell structure & protrusions. Features conserved across the phylum provide new insight into our ancestor’s biology!

Eukaryotes' closest relatives are internally simple syntrophic archaea

Eukaryotes are theorized to have originated from an archaeal phylum Promethearchaeota (formerly 'Asgard' archaea)1,2. The first cultured representatives revealed valuable insight3,4 but are distantly ...

Underground happy hour?
Excited to share our discovery of a new symbiosis between subsurface bacteria and archaea bridged by syntrophic transfer of the smallest alcohol—methanol! @nature.com

Work led by a former student Huang Yan, congratulations!

Methanol transfer supports metabolic syntrophy between bacteria and archaea

Nature - Zhaonella formicivorans produces methanol, for a novel syntrophic interaction, without requiring methylated compounds as an input.
