Evolutionary history of chloroplast genome structure in the genus Passiflora. The structure of the chloroplast genomes was plotted on a tree representing the evolution of the Passiflora genus. In the tree, each subgenus was differentiated by colors: blue for Astrophea, green for Decaloba, red for Deidamioides, orange for Passiflora, and violet for Tetrapathea. In the comparison of the cp genomes, the boxes and dotted lines indicate the direction of the structural inversions, and the red arrows indicate the direction of IR expansions/contractions. *Mitostemma brevifilis shares the same structure with Dilkea retusa, and the species of the Passiflora subgenus obtained in this study share the same structure with Passiflora alata. ^¥cp genomes obtained from the GenBank database.
