Saccharomyces Genome Database provides tools to survey gene expression andfunctional analysis data

Upon the completion of the Saccharomyces cerevisiae genomic sequence in 199 6 [Goffeau,A, et al, (1997) Nature, 387, 5], several creative and ambitious projects have been initiated to explore the functions of gene products or gene expression on a genome-wide scale. To help researchers take advantage of these projects, the Saccharomyces Genome Database (SGD) has created two new tools, Function Junction and Expression Connection. Together, the tools form a central resource for querying multiple large-scale analysis project s for data about individual genes. Function Junction provides information f rom diverse projects that shed tight on the role a gene product plays in th e cell, while Expression Connection delivers information produced by the ev er-increasing number of microarray projects. WWW access to SGD is available at genome-www.stanford.edu/Saccharomyces/.
