One of the main uses of the GO/KEGG is to perform enrichment analysis on gene sets. For example, given a set of genes that are up-regulated under certain conditions, an enrichment analysis will find which GO/KEGG terms are over-represented (or under-represented) using annotations for that gene set. BnPIR collected gene GO and KEGG annotaion of eight rape genomes and you can upload "Interest gene List" to perform enrichment analysis based on hypergenometric test.
