In this tutorial, we briefly illustrate how to search for related genes based on transcriptional expression data (Hirai et al. 2004[PubMed] ) using BL-SOM. Hirai et al. analyzed gene expression and metabolite accumulation profiles of leaves and roots under sulfur- and nitrogen-deficiency conditions using cDNA macroarrays and FT/MS, respectively. In this tutorial, we show how to find genes related to glucosinolate metabolism using only the gene-expression profile.
