Figure 4.
Typical arrangements of QS genes in chromosome II of the Burkholderia cepacia complex (BCC) group. (A) Arrangement of QS genes in the BCC members with cciR/I genes (for example B. cenocepacia J2315 and B. cenocepacia MC0-3); (B) Arrangement of QS genes in BCC members having just one pair of luxR/I homologs (cepR/I) (for example B. cenocepacia AU1054, B. cenocepacia HI2424, B. cepacia GG4, etc.). OriC denotes the origin of replication, solo luxR genes (i.e. those without adjacent I genes) are denoted by black and white ovals, respectively, with the latter indicating two adjacent luxR homologues.
