Fig. 2From: Comparative transcriptomics reveals the conserved building blocks involved in parallel evolution of diverse phenotypic traits in antsCorrelation between module eigengenes and the biological traits (caste, worker sterility, colony queen number and invasiveness). Modules were clustered based on GO term similarities obtained with GOSemSim [93], which computes semantic similarity among sets of GO terms (Additional file 8). Expression of most modules is strongly associated with caste phenotypes. In addition, expression of several of these modules was also associated with other phenotypes, such as obligate worker sterility, colony queen number, and invasiveness. This shows that modules likely play multiple roles, and that their constituent genes have many functionsBack to article page
