Fig. 5.—

Complex history of gene conversion in a Sorghum bicolor mtpt. The aligned characters represent all parsimony-informative sites from a 2-kb mtpt fragment found in grasses along with the corresponding plastid sequences. Shading in the S. bicolor mtpt sequence indicates regions with different phylogenetic histories resulting from different timing of gene conversion events (as shown by corresponding color coding in the species tree). Numbering corresponds to nucleotide position in the Phoenix dactylifera plastid genome.
