Thaumarchaeota Genomes from Multiple Trench Sediments

Diamantina, Kermadec, and Mariana-Yap trench sediments provided 25 high-quality metagenome-assembled genomes (MAGs) of Thaumarchaeota. The dataset includes 18 ammonia-oxidizing archaea (AOA) and 7 non-ammonia-oxidizing archaea (non-AOA) representatives. It was authored by Yue Zhang and last updated on 2026-04-19.

Use Cases

• Comparative genomics of Thaumarchaeota lineages based on the 25 MAGs.
• Analysis of niche differentiation between AOA and non-AOA groups across trenches.
• Study of functional specialization in nitrogen cycling pathways within deep-ocean ecosystems.
• Phylogenetic analysis of Nitrosopumilales order members, including CSP1-1, DRGT01, and Nitrosopumilus.

Strengths

• Includes 25 high-quality metagenome-assembled genomes (MAGs).
• Specifically contains 18 AOA and 7 non-AOA representatives.
• Data sourced from three distinct hadal trench systems: Diamantina, Kermadec, and Mariana-Yap.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the sampled trenches.
