Rhizosphere microbes establish functional interactions with their hosts, impacting plant fitness. To further understand plant effects on microbial composition and functional diversity, this study presents 52 metagenomes and 1,484 metagenome-assembled genomes (MAGs) from soil and the rhizosphere of Antarctic vascular plants. The samples were collected from the Byers Peninsula, Livingston Island (62°S), Antarctica. Analysis of these metagenomes revealed distinct microbial community compositions between rhizosphere and bulk soil samples, with significant differences in functional potential and metabolic pathways. The recovered MAGs represent diverse bacterial and archaeal lineages adapted to extreme Antarctic conditions, providing valuable genomic resources for understanding microbial adaptation to polar environments.
