EUKARYOME is a community-curated research database for nuclear ribosomal 18S rRNA (SSU), internal transcribed spacer (ITS), and 28S rRNA (LSU) markers for all eukaryotes. It compiles well-annotated, non-redundant, high-quality reads for the SSU, ITS, and LSU subsets – separately and combined – for high-accuracy taxonomic reference and chimera recognition. It also offers a number of reference long read sequences that are derived from (meta)genomic, long-read (meta)barcoding and concatenated short Sanger reads – a unique feature that can be used for taxonomic identification and chimera control of third-generation, long-read, high-throughput sequencing data. EUKARYOME relies only on the Linnaean ranks including species, genus, family, order, class, phylum, and kingdom. The EUKARYOME reference database covers all terrestrial and aquatic eukaryotic groups based on nuclear rRNA SSU, ITS, and LSU markers taken separately and combined). A total of nearly 1.8 million entries are contained in the current version of the database.
