CnidBase: The Cnidarian Evolutionary Genomics Database

CnidBase, the Cnidarian Evolutionary Genomics Database, is a tool for investigating the evolutionary, developmental and ecological factors that affect gene expression and gene function in cnidarians. In turn, CnidBase will help to illuminate the role of specific genes in shaping cnidarian biodiversity in the present day and in the distant past. CnidBase highlights evolutionary changes between species within the phylum Cnidaria and structures genomic and expression data to facilitate comparisons to non-cnidarian metazoans. CnidBase aims to further the progress that has already been made in the realm of cnidarian evolutionary genomics by creating a central community resource which will help drive future research and facilitate more accurate classification and comparison of new experimental data with existing data. CnidBase is available at

CnidBase Gene Expression Query. The left screen depicts the CnidBase query form. Search fields include gene symbol, organism, expression level, life history stage, body region, layers, assay types and cell types. The polyp image changes depending on which body region is chosen from the scroll box. The upper right screen shows the result of a query. Assay accessions are linked to the observations of that particular assay (lower right). Sequence accessions are linked to information about a gene including its known homologues and other expression assays.
