Phylogenetic relationships between individual proteins encoded in ETP gene clusters. (a) Two module non-ribosomal peptide synthetase P; (b) cytochrome P450 monooxygenase C; (c) glutathione S-transferase G; (d) ACCS I; (e), dipeptidase J; (f) O-methyl transferase M. Numbers at nodes are bootstrap support values from (left to right or top to bottom) PhyML and WEIGHBOR. Proteins encoded within clusters are on coloured branches, and non-cluster paralogues are on black branches. Consistent cluster relationships across the six proteins are indicated by orange (subclade I), pink (subclade II) and light and dark green (subclades IIIA and IIIB, respectively). Proteins encoded in clusters outside of the main cluster clade are on blue branches. '#2' after taxon name indicates that this is the second cluster found in that species, as per Figure 2.
