Offers public access to a wide variety of plant, fungal and animal genomes. ORCAE is a wikistyle annotation portal. The basic setup of this tool is highly comparable to wiki systems such as MediaWiki, and the information page for each gene can be seen as a ‘topic’ page of a traditional text wiki. It offers functionality to browse, annotate and manage eukaryotic genome annotation projects. Finally, ORCAE is highly dynamic: upon modification of a gene model, all the available information is immediately updated and presented on the gene page.
