IMAS Metadata Catalogue
Antarctic sea ice diatom Nitzschia sp.
This dataset includes the genome assembly and predicted proteome of an Antarctic sea-ice diatom, Nitzschia sp. (most likely Nitzschia stellata). It also contains the endogenous viral element (EVE) sequences identified within this diatom genome, as well as the results of comparative genomic analyses between Antarctic sea-ice diatoms and non-polar diatoms. The Nitzschia sp. genome assembly was obtained through metagenomic binning of Antarctic sea-ice samples.

- Statement
- The Nitzschia sp. genome assembly was obtained from metagenomic data through binning. Assembly completeness was assessed with BUSCO, and the genome was further refined using BlobToolKit. Genome annotation was performed with MAKER2, and the quality of the annotated genes was evaluated again with BUSCO. Endogenous viral elements (EVEs) in the diatom genome were identified using geNomad. Comparative genomic analyses between Antarctic sea-ice diatoms and non-polar diatoms were conducted using OrthoVenn3.
