The effects of the different enzyme inducers on the gene expression profile of the metabolic pathways. a The ten sugars were clustered based on the fraction of the total genes (that each pathway consists of) that was found significantly different in expression compared to glucose for 66 metabolic pathways. The green font indicates down-regulation; the red font indicates up-regulation; the values range from 0 (no gene in the pathway found significantly different in expression) to 1 (all the genes in the pathway were found significantly different in expression). The description of the abbreviated pathway names is given in Additional file 3. The clustering tree or the dendogram displayed was based on the heat map of the hierarchical clustering. b For each enzyme inducer are given the metabolic pathways that their expression was highly affected (the expression of at least 50 % of the genes involved in the pathway was significantly different compared to glucose). The size of the node indicates the fraction of the pathway up- (red font) or down- (green font) regulated
