Relationship between plastid genome size and (A) total (dispersed + tandem repeats) and (B) tandem repetitive DNA content. Species within Campanulaceae are shown in gray, while outgroups (Carpodetus serratus, Helianthus annuus, Pentaphragma spicatum, and Stylidium debile) are shown in black. The lineages of C. americana, shown in purple (Western), orange (Eastern) and green (Appalachian) show high amount of repetitive DNA
