petal co-expression network analysis. Co-expression network model of a subnetwork of 23 genes hypothesized or confirmed to be involved in pheromone biosynthesis. Within the subnetwork, very densely connected groups, vicinity networks (VNs), are identified for (a) exo-brevicomin, highlighted purple, and (b) frontalin, highlighted light blue and orange (showing only the genes of interest.) The gene expression profiles of the intersections of VNs associated to the three colored gene groups are shown in (c) with a total of 31 genes in purple, 38 genes in blue and 84 genes in orange (see Additional file 3)
