The European Nucleotide Archive (ENA) taxonomy

The classification system for source biological organisms for all INSDC records is the NCBI Taxonomy. The ENA team work alongside taxonomists at the NCBI to ensure that all ENA records display the accepted organism name and classification hierarchy. NCBI Taxonomy covers the complete tree of life and also includes other types, such as synthetic constructs and environmental samples. However, it is an incomplete classification system in that it only considers taxa for data that are represented in INSDC records. Users should note that taxa are only displayed if at least one associated ENA record is available.
