## TL;DR

This study explores soil and plant-root microbes in Antarctica to understand how plants influence microbial communities and functions.

## Contribution

The paper provides a large dataset of metagenomes and MAGs from Antarctic rhizosphere and soil.

## Key findings

- 52 metagenomes and 1,484 MAGs were generated from soil and rhizosphere samples.
- The study focuses on microbial interactions in the extreme environment of Antarctica.

## Abstract

Rhizosphere microbes establish functional interactions with their hosts, impacting plant fitness. To further understand plant effects on microbial composition and functional diversity, we present 52 metagenomes and 1,484 metagenome-assembled genomes (MAGs) from soil and the rhizosphere of Colobanthus quitensis and Deschampsia antarctica.

## Linked entities

- **Species:** Colobanthus quitensis (taxon 552857), Deschampsia antarctica (taxon 159298)

## Full-text entities

- **Species:** Deschampsia antarctica (Antarctic hairgrass, species) [taxon 159298], Colobanthus quitensis (species) [taxon 552857]
