Antarctic Sea-Ice Diatom Genome with Viral Elements and Comparative Analyses

An Antarctic sea-ice diatom, likely Nitzschia stellata, genome assembly and predicted proteome are provided by the Australian Ocean Data Network. The dataset includes endogenous viral element sequences identified within the genome and results from comparative genomic analyses with non-polar diatoms. The genome assembly was generated through metagenomic binning of Antarctic sea-ice samples and was last updated on 2026-04-29.

Use Cases

• Study diatom adaptation to polar environments based on the genome assembly and predicted proteome.
• Investigate viral integration and evolution in microbial eukaryotes based on the endogenous viral element sequences.
• Conduct comparative genomic analyses between polar and non-polar diatoms using the provided results.

Strengths

• Includes a complete genome assembly and predicted proteome for a specific Antarctic diatom.
• Contains identified endogenous viral element sequences, adding a layer of virological data.
• Provides results from comparative genomic analyses, offering a direct research output.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
