Figure 1.

The ML tree of the MP clade reconstructed based on the CP and the variation of IR/SC junctions. Numbers at nodes correspond to ML bootstrap percentages (only values <100% are shown) and Bayesian inference (BI) posterior probabilities (only probabilities <1.0 are shown). Genes loss, pseudogenes, inversions (IV), exon and intron loss, in the plastome, are indicated on the branches using coloured squares, rectangles, triangles, stars and oval shapes, respectively. The IR expansion and contraction are shown by blue and red arrow, respectively.
