Figure 1From: Phylogenomic inference of functional divergenceBacterial lineages enriched for functional divergence in GroEL. The thermosome-related sequences are found in certain extremophilic bacteria, perhaps as a result of horizontal gene transfer from archaea. The other highlighted lineages are intracellular pathogens, with the exception of Chloroflexi. The tree was produced by RAxML [6].Back to article page
