Schematic summary of cell morphology and FL-V staining defects observed in mutants lacking PG hydrolases or WalRKSpn regulon members relative to the parent strain. Defects in cell shape and size are traced by peripheral lines, and hashed and solid lines near the middles of cells indicate equatorial, septal, and misplaced rings, ring segments, and puncta that were stained with FL-V. This summary is based on numerous images from independent cultures of each capsulated and unencapsulated mutant (see Fig. 2).
