From: A novel type bacterial flagellar motor that can use divalent cations as a coupling ion

Phylogenetic tree of the stator subunits MotB and MotS of the flagellar motor from Paenibacillus, Oceanobacillus and Bacillus sp. using the neighbor-joining method.
The MotB sequence of E. coli was used as an outgroup. Bar, 0.1 substitutions per amino acid position. The phylogenetic tree was constructed with ClustalW (http://clustalw.ddbj.nig.ac.jp) with 1,000 bootstrap samplings. Paenibacillus sp. TCA20 is shown in red text.
