Fig. 4.

Number shared orthologous and unique genes identified between compared plant species. Each concentric circle corresponds to one species [(1) ArTh, Arabidopsis thaliana; (2) HeBr, Hevea brasiliensis; (3) JaCr, Jatropha curcas; (4) MaEs, Manihot esculenta; (5) PoTr, Populus trichocarpa; (6) RiCo, Ricinus communis; and (7) CrDr, Croton draco]. Blue blocks mark the intersection by pairs (orthologs between two species), yellow blocks reference unique genes for each species (species-specific genes). The number of shared orthologs is shown next to the last concentric circle. C. draco shares the largest number of orthologs with P. trichocarpa (box highlighted with dark blue dotted line) and the least with R. communis (box highlighted pink dotted line). To generate this figure and visualize the multi-species intersections, we used the R package SuperExactTest [42]
