Antarctic endolithic bacterial metagenome-assembled genomes

Bacterial assembled genomes and annotation data from the Antarctic cryptoendolithic communities collected during the XXXI (2015-16) Italian Antarctic Expedition.

The dataset consists of 4 zip archives and 3 files (comma-separated values). Here is a brief summary of their contents:

MAGs: high quality (HQ) and medium quality (MQ) bacterial metagenome assembled genomes.

MAGs_metadata: completeness, contamination, length, N50, GTDB classification for each MAG.

MAGs_HQ_CDS:  translated coding sequences for each high quality MAG.

MAGs_HQ_Annotation: EggNOG annotation files. For each high quality MAG, the following files are included:

eggnog.emapper.annotations: the final EggNOG annotation;

eggnog.emapper.hmm_hits: list of significant hits to eggNOG Orthologous Groups

eggnog.emapper.seed_orthologs: best match of each query within the best Orthologous Group (OG) reported in the eggnog.emapper.hmm_hits file.

Jiangella_Antarctica: Candidatus Jiangella antarctica representative genome (UniValnordMG_2_bin.36.fa) and the extracted ribosomal RNA genes (rRNA.fasta).

Order_MSA: protein multiple sequence alignments using the 120 GTDB bacterial marker genes. These alignments were used to estimate divergence times on orders containing at least 4 CBS, for a total of 19 orders.

Samples_accession: table that relates to the NCBI deposition of the shotgun metagenomes, the following info are included:

NCBI Sequence Read Archive (SRA)

BioProject accession numbers

JGI Integrated Microbial Genomes & Microbiomes site IDs

N50 values

Metadata

Samples_metadata: geographic coordinates, temperature, relative humidity and sampling date are reported.
