The Saccharomyces Genome Database (SGD) integrates information from diverse sources to provide up-to-date descriptions, DNA sequences, mapping data, basic biological information about yeast genes, and much more. The SGD contains all publicly-available DNA sequences for Saccharomyces cerevisiae, which now includes the entire genomic sequence. In addition, the SGD is creating a comprehensive annotated literature summary for every named yeast gene, which we call "Gene Info". The SGD also serves as the S. cerevisiae Gene Name Registry and as the depository for genetic and physical mapping data. This poster provides a brief tour of our Web site, including how to locate information by gene, ORF, DNA sequence, clone, or author name; map location, or simple text and keyword searches. We also show how the database is interconnected to other yeast information resources. Examples of BLAST searches against the complete yeast genome and the retrieval of specific regions of DNA sequence, with or without their restriction map, are highlighted. Literature is provided that describes the community guidelines on gene-naming in S. cerevisiae, and how genetic nomenclature conflicts are resolved.
