Figure 4 From: Inter-genomic displacement via lateral gene transfer of bacterial trp operons in an overall context of vertical genealogy Phylogenetic tree (radial view) showing that free-standing TrpAa domains, TrpAa components of TrpAa•TrpAb fusions, and TrpAa components of TrpAa•TrpAb_phz fusions are all distinct from one another. The position of some TCG groups are marked at the top. TrpA• fusion domains are color-coded to indicate their expected TCG placements if convergent evolution were not a factor. The TCG-1 grouping is distinctly divergent from all of the other free-standing TrpAa sequences.Back to article page
