Structural organization of the phaseolotoxin biosynthetic gene cluster (pht cluster). The different CDs are represented by arrows indicating the direction of transcription. The grey arrows indicate the principal genes identified and characterized by researchers. The different loci and operons are indicated by black bands. The pht cluster is located in the tox island corresponding to the phaseolotoxin genomic island. The genomic map of the tox island and the regions bordering it are shown.
