Fig. 6. The trade-off between being virulent in insecta and resistant to the phage(-related) particles of non-kin strains, or being resistant to the phage(-related) particles of kin strains.
The cartoons explain the results obtained following the various competition assays from this study on the different Pf-5 LPS mutant derivatives (a, Pf-5 wild-type; b, Δobc4; c, Δobc5; d, Δobc4Δobc5; e, ΔwbpL; f, ΔPFL_0524). g Model demonstrating the trade-off that Pf-5 faces when confronted with different environments and their inhabitants. Lipid A: dark blue, inner core: dark grey, outer core: light grey, O-PS: purple (OBC4) and pink (OBC5). To represent the immune defense of the insect, the structure of cecropin A, an antimicrobial peptide (AMP, [11]), is shown. Phylogenetically closely related bacteria and phage(-related) particles produced by these kin strains are shown in light blue. Phylogenetically distantly related bacteria and phage(-related) particles produced by these non-kin strains are shown in yellow/orange.
