Antarctic Sea-Ice Diatom Genome Assembly and Comparative Analysis

Antarctic sea-ice ecosystems are the focus of this high-quality draft genome assembly for the diatom Nitzschia sp. The dataset includes comparative genomic analyses with another Antarctic diatom, Fragilariopsis cylindrus, and temperate species. Author Chuan Zhai published the data on figshare in April 2026.

Use Cases

• Identify orthologous genes associated with polar stress response based on comparative analyses mentioned in the description
• Study genome structure and transposable element content based on the reported 27.25% TE composition
• Analyze gene family contractions in pathways like solute transport and endocytosis as described
• Investigate endogenous viral elements (EVEs) related to Metaviridae found in the assembly

Strengths

• High-quality draft genome assembly for a key Antarctic primary producer
• Includes comparative analyses with other diatom species, highlighting shared and unique genomic features
• Reports specific genomic metrics, such as transposable elements accounting for 27.25% of the assembly

Limitations

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