Antarctic Sea-Ice Diatom Nitzschia sp. Genome Assembly and Comparative Analysis

A high-quality draft genome assembly of an Antarctic sea-ice diatom, Nitzschia sp., published by Chuan Zhai on figshare in April 2026. The 11.8 MB FASTA file includes genomic data used for comparative analysis with another Antarctic diatom, Fragilariopsis cylindrus. The analysis identified shared stress-response genes and specific genomic features like transposable elements accounting for 27.25% of the assembly.

Use Cases

• Comparative genomics analysis based on shared orthologous genes for stress response.
• Studying genome evolution and adaptation based on contracted gene families like solute carrier transporters.
• Investigating viral and mobile genetic elements based on the identified endogenous viral element (EVE) and transposable elements.

Strengths

• High-quality draft genome assembly specifically for an Antarctic sea-ice diatom.
• Includes a quantified proportion of transposable elements (27.25% of the genome).
• Comparative analysis performed against another key Antarctic diatom species.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Data scale is small (11.8 MB), which may limit the scope of certain analyses.
