Figure 5.

Phylogenetic analysis of the 59-be sites found in Vibrio chromosomal integrons. Each terminal branch is colour-coded according to the organism hosting the particular 59-be site it represents (see legend). The tree displayed in the best distance neighbor-joining tree obtained using PAUP*. Percent bootstrap support values represent the consensus of distance neighbor-joining trees obtained from 100 pseudo-replicates of the dataset. They are only displayed for important backbone nodes when the value exceeds 50%. 85 internal nodes are supported with >80% bootstrap value, 20 of which represent mixed species clades.
