The Arabidopsis Information Resource (TAIR; www.arabidopsis.org) is a comprehensive resource of Arabidopsis biology for plant scientists. TAIR integrates information about genes, proteins, gene expression, mutant phenotypes, biological materials such as DNA and seed stocks, genetic markers, genetic and physical maps, biochemical pathways, genome organization, publications and the research community. The first part of this hands-on workshop will focus on accessing, downloading an analyzing expression Arabidopsis microarray data stored in TAIR. Specifically, we will cover the following tasks: Finding and understanding expression data for gene(s) of interest; Classifying clustered expression data based on functional categorization using the Gene Ontology assignments; Finding over-represented oligomers within a given set of genes using MotifFinder; Finding microarray experimental datasets using the Microarray Experiment Search; Investigating the behavi or of sets of genes in a variety of experiments using the Microarray Expression Search; and Mining for similarly expressed genes across a variety of experiments using VxInsight and Java TreeView. In the second part of the workshop we will explore the uses of the Arabidopsis metabolism database, AraCyc, for investigating plant biochemical pathways. Using the Omics Viewer tool in AraCyc, we will analyze sample microarray data to identify changes in the expression of genes involved in metabolic pathways. The viewer can be used to overlay other large-scale data such as those resulting from proteomics and metabolomics experiments. Finally, we will demonstrate how MetaCyc (www.metacyc.org) can be used to predict metabolic pathways in other annotated genomes.
