Fig. 5

Gene expression modules were obtained from co-expression analysis using WGCNA. Each colour represents an expression module. The figure of the organ near the module indicates that the genes within the module are specific to the expression of that organ. The squares and circles next to the modules indicate that the genes within the module are significantly enriched in shell genes or softcore genes. In addition, the functional descriptions next to the module represent the GO terms for the gene enrichment within the module
