Web interface. Panel A shows the starting page for PlantTFDB. The tree menu in the center of the page allows browsing by species or by TF families. Panel B shows part of a typical page for a TF family; a short description and the domains that are important for the definition of the family are shown. Panel C shows part of the page for gene details, which is typical for each member of the DB. Alternative gene names are listed. Links to the genome databases and to the sister TFDBs where orthologs were found are provided.
