FIG 4.

Visualization of interactions in the GS₄₈ and FSS₂₃ populations using PCA (A and B) and schematic models (C, D, and E). The GS₄₈ and FSS₂₃ majority rule consensus interaction matrices were used as input for the PCA using default settings. (A) First and second component of the PCA analysis of the GS₄₈ interaction matrix. All variation falls within the 95% CI of Bacillus (red line). (B) First and second components of the PCA analysis of the FSS₂₃ interaction matrix. All variation falls within the 95% CI of Bacillus (red line). (C) Explanatory diagram of the meaning of the interactions between different genera in panels D and E. (D) Interaction diagram of the GS₄₈ population. (E) Interaction diagram of the FSS₂₃ population. A, amensal interactions; R, reciprocal interactions. In black are all interactions, and in purple are all exDNase-associated interactions.
