18S rRNA TAREuk Protist Database Optimized for the Baltic Sea

A cleaned 18S rRNA PR² database with WoRMS taxonomy and NCBI reference sequences, optimized for the Baltic Sea. The subset represents the in silico PCR product of the larger database, restricted to the amplicon region targeted by the TAREuk primer pair. The dataset was last updated on 2026-05-12 by Juliane Romahn.

Use Cases

• Classifying protist sequences from Baltic Sea samples based on the optimized reference database.
• Benchmarking metabarcoding pipelines using the TAREuk primer pair amplicon region.
• Studying protist diversity and taxonomy in the Baltic Sea marine environment.

Strengths

• Dataset is optimized for a specific region (Baltic Sea) and primer pair (TAREuk).
• Includes WoRMS taxonomy and NCBI reference sequences for improved classification.
• Released under a permissive CC-BY-4.0 license for open use.

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 its focus on the Baltic Sea.
