Fig. 6.

Evolutionary history of the bmp gene cluster in Pseudoalteromonas.

A. Inferred ancestral gene clusters are mapped onto a condensed species phylogeny (animated from Fig. 2). The distribution of each gene (coloured lines) is indicated based on presence or absence in that lineage (truncated or missing lines = absence).

B. Versions of the gene cluster (A, C, D or E) observed in relation to the tree with evolutionary events indicated as maintenance, loss or modification. Losses include complete or partial deletion of the gene cluster. An insertion in bmp1 is the only modification observed (indicated with a star). Percent sequence identities between homologues indicated.
