Korarchaeota - Wikipedia
The Korarchaeota is a proposed phylum within the Archaea. [3] The name is derived from the Greek noun koros or kore, meaning young man or young woman, and the Greek adjective archaios which means ancient. [4] They are also known as Xenarchaeota. The name is equivalent to Candidatus Korarchaeota, and they go by the name Xenarchaeota or ...

archaea, (domain Archaea), any of a group of single-celled prokaryotic organisms (that is, organisms whose cells lack a defined nucleus) that have distinct molecular characteristics separating them from bacteria (the other, more prominent group of prokaryotes) as well as from eukaryotes (organisms, including plants and animals, whose cells conta...

Sep 29, 2023 · Terrestrial Korarchaeota gained many cas and CARF genes indicating they may need to manage viral infections. Together, our study provides new insights into these early diverging Archaea and suggests that gradual gene gain and loss shaped their adaptation to different thermal environments.
