FIGURE 4.
The pan-genome of streptomycetes. (A) Flower plots showing the core gene number (in the center) and strain-specific gene number (in the petals) in 31 streptomycete strains. (B) Flower plots showing the core gene number (in the center) and strain-specific gene number (in the petals) in the marine-derived subgroup. (C) Flower plots showing the core gene number (in the center) and strain-specific gene number (in the petals) in the multiple sources subgroup. The numbers under the strain name represent the total number of coding proteins. Blue indicates the marine-derived subgroup and orange indicates the multiple sources subgroup.
