Schematic representation of the four strains used in this study. (a) PS533 (wild-type), (b) Coat-less PS4150 (ΔcotE::tet ΔgerE::spc), (c). DPA-less FB122 (ΔspoVF::tet ΔsleB::spc). The brown layer represents the inner and outer coat, the orange layer the outer membrane, the green layer the cortex, the second orange layer the cell membrane and inner membrane. The core contains DPA, if not deleted. Strain FB113 (ΔcwlJ::tet ΔsleB::spc) in the dormant form has similar structure organization as PS533 (a), and when germinated might be structurally comparable to FB122 (c).
