Figure 1From: Multiple major increases and decreases in mitochondrial substitution rates in the plant family GeraniaceaeExtreme divergence of mitochondrial genes in Pelargonium hortorum. Shown are ML trees based on synonymous (dS) sites for protein genes or all sites for rRNA genes. All tree topologies were completely constrained as described in Methods. All dS trees are drawn to one scale, while all rDNA trees are drawn to a different scale (see bottom right). Abbreviations: Pe, Pelargonium; Pl, Plantago; E, Erodium. (A) Mitochondrial gene trees are based on 1,275 (atp1), 1,119 (cob), 1,413 (cox1), 723 (cox2), 690 (cox3), 805 (LSU rDNA), 1,395 (SSU rDNA), and 198 (nad1) NT. (B) Chloroplast gene trees are based on 1,497 (matK), 2,172 (ndhF), 483 (petD), 1,377 (rbcL), and 417 (rps11) NT. (C) Nuclear gene trees are based on 945 (aco, 1-aminocyclopropane-1-carboxylate oxidase), 1,245 (acs, 1-aminocyclopropane-1-carboxylate synthase), 2,226 (etr, ethylene receptor), and 1,667 (SSU rDNA) NT.Back to article page
