Evolution of cnidarian mt organization. A. Summary of relationships of higher cnidarian taxa according to nc Small and Large Subunit rRNA data [37], and the organization of mt genomes. Note that in [15] only the size of mt chromosome carrying rnl was examined. B. Summary of relationships within the genus Hydra based upon our ML and Bayesian analyses of partial cox1 data, rooted with other hydrozoan sequences from GenBank (accession numbers are given after each species name). Support values >50 are shown above branches (ML bootstraps/Bayesian posterior probability, * = 100 in both analyses). Sequences from this study are bold. Expected mt genome organization is shown in grey.
