From: Comparative mitogenomics indicates respiratory competence in parasitic Viscum despite loss of complex I and extreme sequence divergence, and reveals horizontal gene transfer and remarkable variation in genome size

Fig. 3

The high divergence of Cob and Cox1 in Viscum relative to other angiosperms pales in comparison to the extreme divergence of these proteins in many diverse lineages of eukaryotes. A constrained topology was enforced for protein maximum likelihood (RAxML, mtRev + G + I) branch-length estimation. Note that angiosperm sampling was deliberately chosen to include representatives of the three most divergent lineages of angiosperm mitogenomes besides Viscum. The three representatives are Pelargonium x hortorum [44], Silene conica [17], and Plantago rugelii [45]. See also Fig. 1 and Additional file 1: Figure S2 for angiosperm-only phylogenetic trees that include both Viscum and S. conica (and the high-rate S. noctiflora, too). Tetrahymena pyriformis and Kudoa hexapunctata branch lengths are shown reduced by a factor of 2
