Abstract Genetics Comprehensive Review: WormBook WormBase: An Information Resource for Research of Caenorhabditis elegans and related nematodes. Raymond Lee and WormBase Consortium. Division of Biology, California Institute of Technology, Pasadena, CA 91125 and www.wormbase.org. The goal of WormBase is to provide a knowledge environment to facilitate further research with C. elegans and related nematodes. We maintain a database, extract information from the literature, and disseminate integrated knowledge via the WWW. Information includes complete genome sequences, developmental cell lineages, neural circuit maps, and extensive genetic analyses that make functional connections between the genome, development, anatomy, and physiology. To allow rapid and easy access of available content, WormBase provides Web pages that focus on special topics, e.g. Gene page, which contains summaries of everything that is known about a gene. Also, users can synthesize complex queries using tools such as WormMart, an interface based on BioMart. For power users, we offer FTP downloads of all of our data and software, and we provide directions for building local mirrors. To keep up with the rapid growth of research literature, we update our database every three weeks. But to ensure comparability between large-scale analyses, we maintain a stable version every ten releases. Sequence Homology Literature Query Tool: Textpresso Completing its functionality as a knowledge portal, WormBase integrates with related services: Textpresso, a primary literature search engine, and WormBook, a collection of expert-written chapters about C. elegans biology. Since its inception in 2000, WormBase has become an indispensable resource for C. elegans researchers. Going forward, a new focus will be on comparative genomics as several other nematode genomes are being sequenced.
