Occurrence statistic of secondary metabolite pathways in 24 KEGG species. For each secondary metabolic pathway of the KEGG database, the number of plant species containing it out of all 24 plant species used in this study are displayed. A pathway was considered present in a given species if at least one enzyme gene from this species was assigned to this pathway.
