NCBI Taxonomy - TSV
NCBI Taxonomy (National Center for Biotechnology Information Taxonomy) is a database that systematically organizes the classification and nomenclature of all organisms registered in public sequence databases, maintained by the National Center for Biotechnology Information in the United States. It currently covers approximately 10% of described species on Earth and plays a crucial role in linking genetic sequence data with biological classification. The database hierarchically organizes major organism groups including Archaea, Bacteria, Eukaryota, and Viruses, and is widely used worldwide as a foundation for biomedical research and bioinformatics analysis.
