Figure 2.

Order of arrangement of 519 orthologs on chromosomes of 5 representative Prochlorococcus strains (LL1, LL3, LL6, HL3 and HL4). The red and blue lines join the locations of pair of orthologs on the linearly depicted chromosomes. Red lines indicate presence of the orthologous pairs on the same strand (either +/+ or -/-) of the two chromosomes they join, while the blue colour indicates the presence of the orthologs on different strands (+/- or -/+). Chromosomal scales are shown in megabase pairs (MB) and 0 MB represents the predicted origins of replication for the 5 strains.
