The phylogeny of cpDNAs. (A) The cpDNA phylogeny based on analysis of 50 concatenated proteins. The phylogeny includes major green plant and algal lineages and the outgroup Cyanophora. The bootstrap support values from maximum parsimony/neighbor joining/maximum likelihood analyses are labeled near each node. (B) Estimated inversion distances considering 85 common genes on the cpDNA phylogeny. There is an increase of rearrangements on branches leading to C. reinhardtii. and C. vulgaris, from a common ancestor indicated by an arrow.
