Figure 4. Relationship of Hodgkinia to other α-Proteobacteria based on small subunit ribosomal DNA sequences.

Figure 4

By itself, this maximum likelihood tree gives moderate support (81/100 bootstrap trees) for the grouping of Hodgkinia with the Rhizobiales. The twenty highest scoring positions for the Hodgkinia clade under a non-homogenous GC content model are indicated with black circles, and provide additional support for Hodgkinia's grouping in the Rhizobiales. Abbreviations are Mcas, Magicicada cassini; Dswa, Diceroprocta swalei; and Dsem, Diceroprocta semicincta. Asterisks indicate 100% bootstrap support; values less than 70% are not shown. Scale bar denotes substitutions per site.
