Series of Functional and Physical Losses of Plastid Genes.

Graphical summary of the number of gene losses (A) and the losses of functional classes of genes (B) based on the reconstruction of plastid gene contents at ancestral nodes in Orobanchaceae. Pseudogenization is illustrated above the branches, whereas gene deletion is shown below the branches. In (A), an arrow indicates the correct placement of a value, and in (B), dots mark loss-of-function deletions (i.e., those without pseudogenization at any of the parent nodes).
