Figure 5. Learned phyloblocks identify a new island and the highly variable capsular polysaccharide and lipopolysaccharide synthesis gene cluster (cps-lps).

Nonubiquity phyloblocks: those missing in at least one of the 11 reference chromosomes. Complex phyloblocks: those requiring more than one gain/loss event to reconcile the phylotype with the genome tree of Fig. 1. As a percentage of their combined 411 kbp, the learned phyloblocks mapped either to the training islands (81.9%), the two newly indicated regions (12.0%), insertion sequences (2.1%), or to small scattered regions that did not show hallmarks of islands (4.0%). Red segments: the 11 final islands (including a tandem array of Kpn21L and Kpn11L). Circles, the two newly indicated regions.
