## TL;DR

Scientists sequenced the genome of an archaeon found in Antarctic rocks, revealing details about its genetic makeup and survival in extreme conditions.

## Contribution

The study presents a new draft genome of an uncultured archaeon from Antarctic endolithic communities.

## Key findings

- The archaeon's genome is 1.99 megabases in size.
- It encodes 2,405 predicted protein-coding genes.
- The genome offers insights into extremophile microbial diversity and function in Antarctic environments.

## Abstract

A draft genome sequence was assembled and annotated for an uncultured archaeon reconstructed from shotgun metagenomes obtained from Antarctic endoliths. The assembled genome is 1.99 megabases and encodes 2,405 predicted protein-coding genes. This genome sequence provides insights into the microbial diversity and functional potential of extremophiles inhabiting Antarctic rock environments.
