The BASC system, provides tools for integrated mining and browsing of genetic, genomic and phenotypic data. The BASC demonstration server provides access to raw and analysed information for Brassica species and comparative information with Arabidopsis. We can use the tools within the Brassica BASC server to identify candidate genes for traits, conduct genome comparisons with Arabidopsis, identify syntonic regions and view gene expression profiles. The integration of BASC modules allows researchers to gain a comprehensive view of diverse Brassica genetic, genomic and phenotypic information. This chapter demonstrates the application of this resource, through the identification of candidate genes for an observed seed oil quality trait in Brassica napus.
