Clustering analysis of transcript expression profiles. The hierarchical clustering is divided into 20 groups, which was further subdivided into 81 subgroups (colored lines in each cluster). Only the cluster groups containing the biosynthetic genes (CYP79A1, CYP71E1 and UGT85B1) is displayed on the figure. The complete overview of all cluster groups can be found in Additional file 3. The number of genes in each cluster is listed in parenthesis next the cluster number. The grey field represents the span of all the expression profiles in a single cluster. The dashed line represents the concentration of dhurrin pr. mg tissue through the grain development in relation to the expression profiles
