Hierarchical clustering dendrogram of all differentially expressed genes (DE) (left) in Spodoptera exigua larvae with different diet treatments clusters the 2585 DE in 6 clusters using a cut-of at 50% (red line). Expression patterns were visualized and the number of genes (N = #) per cluster is indicated (middle). Green colour coding indicates host diet treatment, larvae fed with B. oleracea, N. tabacum and Z. mays are shown with increasing darker shades of green. Each diet treatment consisted of three replicates. The heatmap (right) shows the expression pattern of the DE genes, black lines indicate the cluster devision. Each column corresponds to larvae from different diet treatments as indicated by the colour scheme
