# Metagenome-assembled genomes from mineral tundra soils in Rásttigáisá, northern Norway

## TL;DR

This paper presents 59 new microbial genomes from tundra soils in northern Norway, revealing insights into the diversity of these under-studied ecosystems.

## Contribution

The study provides novel metagenome-assembled genomes from mineral tundra soils, expanding our understanding of tundra microbial diversity.

## Key findings

- 59 non-redundant MAGs were recovered from Rásttigáisá tundra soils.
- MAGs were primarily from bacterial phyla Candidatus Dormibacterota, Verrucomicrobiota, and Acidobacteriota.
- Four archaeal MAGs were identified, all belonging to the genus Candidatus Nitrosopolaris.

## Abstract

Microbial communities in tundra soils remain largely unknown despite their important roles in the cycling of greenhouse gases. Here, we report 59 non-redundant metagenome-assembled genomes (MAGs) recovered from mineral tundra soils in Rásttigáisá, northern Norway. The MAGs were obtained by clustering contigs according to tetranucleotide frequency and differential coverage and were manually curated to remove contigs with outlying GC content and/or mean coverage. Most MAGs were assigned to the bacterial phyla Candidatus Dormibacterota (n=12), Verrucomicrobiota (n=10), and Acidobacteriota (n=9). All archaeal MAGs (n=4) belong to the genus Candidatus Nitrosopolaris (phylum Thermoproteota). The 59 Rásttigáisá MAGs expand our knowledge of the diversity and ecological roles of tundra microbiomes.
