Fig. 5. Phylogenomic analysis of plastid genomes.
Best maximum-likelihood Brachypodium phylogenomic tree based on plastomes. Most branches of main clades show strong support (see Supplementary Fig. 2a). B. stacei and B. hybridum-S plastotypes (red); B. hybridum D plastotypes (olive); B. distachyon EDF + clade (blue); B. distachyon S + group (green); B. distachyon T + clade (yellow). Stars highlight plastid capture events between the B. distachyon groups (see also Supplementary Fig. 2b).
