Fig. 6

Biosynthetic gene clusters predicted using antiSMASH from genome sequences of 45 pig tonsil isolates that were selected by different colony morphologies and antagonistic activity in bioassays. Different classes of secondary metabolites are represented with different colors. The x-axis shows how many of the different biosynthetic gene clusters (BCGs) are present in the genomes of each strain listed on the y-axis (extended table provided in Additional Table 4). Gene clusters of the same type are represented by the same color and sometimes appear two or more times in the same genome when the sequences of the genes within the BGC are not identical (e.g., there may be two different BGCs producing a siderophore ion chelating molecule)
