Summary of the effects of queen pheromone on gene expression and splicing, showing the extent of overlap between species. a, b Venn diagrams showing the number of significantly differentially expressed or differentially spliced genes per species (α = 0.05 after false discovery rate correction). Parentheses in the outermost areas show this number as a percentage of all transcripts measured in the focal species, while parentheses in the inner areas show the number of overlapping genes as a percentage of the maximum number that could have overlapped (this number depends on the number of detectable orthologs and the number of significant genes). Asterisks denote the one overlap that was significantly higher than expected by chance (hypergeometric test, p < 0.0001). B. terrestris is omitted because there was only one significantly differentially expressed gene, and no differentially spliced genes. c Graphical overview of the amount of similarity in pheromone sensitivity in the set of 3465 orthologous genes. The four inner rings show the pheromone sensitivity of each gene (redder colours indicate increased sensitivity), and the genes have been clustered according to coexpression pattern, as shown in the central dendrogram. The coloured outer ring shows the assignment of genes to modules, and the grey area marked m0 refers to genes that were not assigned to a module. d Orthologous genes tended to show a similar level of sensitivity to queen pheromones for each pair of species. The numbers give Spearman’s ρ (Benjamini-Hochberg corrected p < 10−7 in all cases)
