Strains for which the genome sequence has been determined are boldfaced. Species and strains examined in this study for the presence or absence of individual genes from the SHP operon (CytB/mDHC-SHP-sDHC) are indicated by a (+) or (-). A question mark indicates that they were not found with our probes, but could still be present. The numbers of base differences in the 16S rRNA of each strain and species is relative to Rb. sphaeroides 2.4.1. Strains and species are arranged in order of increasing divergence.
