Phylogenetic trees of the studied species and of plastome gene loss. Phylogenetic tree of the investigated hemiparasite plastomes, decorated with the branch of specific inactivational events for the listed genes. These inactivational events included deletions, frameshifts and/or stop codon generation. The inset tree shows the relationships between the species studied in this manuscript to three others that have been previously investigated, Pedicularis cheilanthifolia, Schwalbea americana, and Triphysaria versicolor [19, 20]. The inset tree is from McNeal et al. 2013 [32] and the other tree is from MrBayes (as described in Methods). The branch lengths of the large tree are proportional to the number of substitutions per site with the scale shown at the bottom. The number 1 at each node is the posterior probability, the likelihood that the tree is correct
