Undinarchaeota Genomes and Phylogenies for DPANN Archaea Evolution

12 metagenome-assembled genomes of the Undinarchaeota phylum provide insights into the debated evolution of DPANN archaea. The repository includes original contigs, protein annotations, and files for phylogenetic analyses involving 364 archaeal reference genomes. This dataset was produced by researchers including Nina Dombrowski and is associated with an open-access publication.

Use Cases

• Reconstructing archaeal phylogeny based on concatenated protein sequences from 364 genomes.
• Analyzing genome size and metabolic capabilities of Undinarchaeota based on annotated protein files.
• Investigating horizontal gene transfer events between DPANN archaea and their hosts using provided genomic data.
• Testing phylogenetic placement hypotheses for the DPANN superphylum using the supplied alignment and tree files.

Strengths

• Includes 12 distinct metagenome-assembled genomes (MAGs) of a novel archaeal phylum.
• Phylogenomic analyses are based on a broad set of 364 archaeal reference genomes.
• Repository provides raw contigs, annotated proteins, and multiple processed files for phylogenetic reconstruction.

Limitations

• Row count and exact file sizes are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
