Figure 1

Two-way hierarchical clustering analysis heat map and dendrogram of mrjp gene expression data over all honeybee castes, sexes and groups. Branch lengths in dendrograms produced from cluster analysis correspond to the relative degree of similarity between branches. Differential gene expression is represented for all genes as a color gradient across all samples from deep blue (lowest) to light yellow (highest). The expression values were log transformed and visualized using MultiExperiment Viewer (MeV) version 4.9. (a) Relative gene expression across all honeybee groups and body sections. The dendrogram for the clustering of the mrjps was generated using data of all three body sections and is exemplarily shown for the thorax. The complete heat map that served as base for the clustering of the genes is shown in Additional file 1: Figure S2. Relative gene expression values are shown in brackets. (b) Gene expression normalized to caged workers. The normalized gene expression values are shown in brackets.
