Heatmap for the hierarchical clustering of the differentially expressed brain gene profiles of nurse and forager honey bees.
Rows correspond to 50 clusters obtained from 1,058 DEGs by the k-means algorithm. Columns represent samples. The scale bar indicates z-scores of gene expression values, with highly expressed genes depicted in dark red low-expressed genes depicted in dark blue. The heatmap that shows the hierarchical clustering of all 1,058 DEGs without clustering is provided in (Supplementary Fig. S3).
