(A) Clones aligned to the corresponding fragment of genomic DNA on the cosmid map of pCosBG. (B) Cosmid map. Sites on the map are as follows: B, BamHI; E, EcoRI; H, HindIII; S, SalI. (C) Arrangement of gsp gene cluster in B. cepacia strain KFI, which has 83 to 98% sequence similarity with BG164R gsp genes. The arrows indicate the positions of insertions of the transposon into the GSP operon.
