Branching order of bacterial phyla (Ciccarelli et al., 2006)

Source: Wikipedia, the free encyclopedia.

There are several models of the Branching order of bacterial phyla, one of these was proposed in 2006 by Ciccarelli et al. for their iTOL project.[1]

This tree is based on a concatenated set of conserved protein and not 16S rRNA (cf. Branching order of bacterial phyla (Woese, 1987)).

Deltaproteobacteria

Acidobacteria

The arrangement of the various phyla differs from that of 16S, but may be due to

Firmicutes
. Nevertheless, the last common ancestor was between Bacteria and Archaea+Eukarya.
