Signature sequences in diverse proteins provide evidence for the late divergence of the Order Aquificales.

International microbiology : the official journal of the Spanish Society for Microbiology - 1 Mar 2004

Griffiths Emma, Gupta Radhey S

Abstract excerpt

The Aquificales species are presently believed to be the earliest branching lineage within Bacteria. However, the branching order of this group in different phylogenetic trees is highly variable and not resolved. In the present work, the phylogenetic placement of Aquificales was examined by means of a cladistic approach based on the shared presence or absence of definite signature sequences (consisting of...
