A. Variation among Penstemon taxa: the ycf1 fragment at the SSC-IRb junction (JSB) in P . dissectus , P . palmeri , and P . cyaneus . B. Successive expansions of the IR regions into the SSC region observed in the genus Plantago . C. Total inversion of the IRa-SSC-IRb plastome segment in the Orobanchaceae genera C . paramensis and P . hallaisanensis . D. A reduction in IR length associated with an expansion of the LSC region in H . rhodopensis compared to our basal lineage, Olea europaea .
