ENAPortal Search Studies

Search the European Nucleotide Archive (ENA) for sequencing studies using text queries or taxonomy filters. Returns study accessions, titles, submitting centers, and publication dates. ENA is the world's largest repository of nucleotide sequences (>3 billion records). Supports powerful query syntax: use 'description="keyword"' for text search, 'tax_tree(TAXID)' for taxonomy-based queries, or combine with AND/OR. Example: searching 'description="SARS-CoV-2"' returns COVID-19 sequencing studies.
