From: Complete plastid genomes from Ophioglossum californicum, Psilotum nudum, and Equisetum hyemale reveal an ancestral land plant genome structure and resolve the position of Equisetales among monilophytes

Figure 6

Phylogenetic history of genomic changes during monilophyte evolution. The most parsimonious reconstruction of genomic changes was plotted onto the ML topology from Figure 5. Homoplasious changes are boxed. All genomic changes involve the plastid genome, except for the gain of the mitochondrial atp1i361 intron. Genomic changes listed for Polypodiopsida indicate that they are synapomorphic for the four complete cpDNA sequences (Alsophila spinulosa, Adiantum capillus-veneris, Pteridium aquilinum and Cheilanthes lindheimeri), but many of them will not necessarily be synapomorphic for all Polypodiopsida.
