Implication

Database report demonstrates expansion to over 55,000 organisms with enhanced functional annotation, highlighting improved resources for comparative genomics and clinical testing.

Key Points

  • To describe the expansion, data access improvements, and functional annotation initiatives across viral, prokaryotic, and eukaryotic branches in NCBI's Reference Sequence (RefSeq) database.
  • Curated non-redundant reference genomes, transcripts, and proteins by combining primary sequence submissions from INSDC with computational pipelines and expert manual curation.
  • Integrated high-throughput experimental evidence, including RNA-Seq data, to refine gene models and functional features in vertebrates, plants, and other taxa.
  • Established updated management workflows for prokaryotic genome sequences and standardized protein nomenclature.
  • RefSeq release 71 expanded to encompass sequences from over 55,000 organisms, spanning more than 4,800 viruses, 40,000 prokaryotes, and 10,000 eukaryotes.
  • Implemented comprehensive functional curation frameworks to provide standardized data for comparative genomics, taxonomic validation, and clinical sequence interpretation.
