Comparison of plastomic structures in Ranunculeae. a Scenarios of gene losses, additions, pseudogenizations, and relocations along the phylogenomic tree of Ranunculeae. The tree was generated based on the 78 protein-coding plastid genes (see Fig. S4 for the whole tree). b Variations of the LSC, IRs, and SSC region boundaries (see details in Fig. S5). The ψ-symbol shows putative pseudogenes. IR, inverted repeats; SSC, small single-copy; LSC, large single-copy
