Description

<jats:p> Unlike all other archaeal lineages, ammonia-oxidizing archaea (AOA) of the phylum <jats:named-content content-type="genus-species">Thaumarchaeota</jats:named-content> are widespread and abundant in all moderate and oxic environments on Earth. The evolutionary adaptations that led to such unprecedented ecological success of a microbial clade characterized by highly conserved energy and carbon metabolisms have, however, remained underexplored. Here, we reconstructed the genomic content and growth temperature of the ancestor of all AOA, as well as the ancestors of the marine and soil lineages, based on 39 available complete or nearly complete genomes of AOA. </jats:p>
