Fig. 1From: 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 Viscum genes are extremely divergent relative to genes of other angiosperms with sequenced mitogenomes (see Fig. 3 for comparison to two divergent angiosperms, Plantago and Pelargonium, for which only a few gene sequences are available). A constrained topology was enforced for maximum likelihood (RAxML, GTRGAMMA) branch-length estimation on the basis of a concatenated alignment of all three codon positions of the nine best-conserved protein genes in Viscum scurruloideum (atp1, atp6, atp9, ccmC, cob, cox1, cox2, cox3, rps12; see [2])Back to article page
