Fig. 1: A sample of 22 luxIR-like containing genomic islands from our dataset.

The direction of each arrow indicates whether that feature is annotated on the forward strand (pointing right) or reverse strand (pointing left). Marked by an asterisk are those that have at least another LuxIR couple elsewhere on the native genome. The fourth and fifth GIs from the top are the same species yet come from two distinct assemblies (GCF_003443555.1 and GCF_000154745.2, respectively). LuxIs are shown in purple and LuxRs in red, whereas protein-coding genes involved in genetic mobilization are displayed in shades of orange and green. The native luxIR counterpart is not represented in this figure. The representation of the entire set of 259 GIs identified in this study are available as Dataset S1.
