Figure 2

Extensive rate variation in Geraniaceae mitochondrial genes. Shown are ML trees based on synonymous (dS) or nonsynonymous (dN) sites for protein genes or all sites for rRNA genes. All tree topologies were completely constrained as described in Methods. To emphasize branch length disparities, taxon names were moved to the right of each tree. Unlabeled branches in the cox1 trees are the same species shown for rbcL. The top three trees are drawn to the same scale, while the bottom three trees are drawn at five times that scale (see scale bars). Abbreviations: Pe, Pelargonium; Pl, Plantago; E, Erodium; G, Geranium. Gene trees are based on 1,413 (cox1), 1,377 (rbcL), 1,471 (mitochondrial SSU rDNA), and 1,667 (nuclear SSU rDNA) NT.
