Figure 3: Whole transcriptome analysis of Bombus impatiens workers’ brain in the presence of the queen and the brood.A) Heatmap representing color-coded expression levels of differentially expressed genes (DEGs) in worker’s brain in all model comparisons. Each column represents individual samples, and each row represents the expression level of selected gene. B) Venn diagram showing the number of DEGs in workers’ brain in response to treatment or to the queen presence. Data are based on 24 libraries of workers’ brain (6 replicates per treatment). Pair of newly emerged workers were assigned to four treatments and kept for three days with the queen (CQ), young brood (CB), the queen and young brood (CBQ), or alone (C).
