FIG 2 .

Abnormal forespore morphology in ΔcwlD and ΔpdaA sporulating cells. (A) TEM analyses of sporulating cells of the wild-type, ΔgerS, ΔcwlD and complement, and ΔpdaA and complement strains at 23 h. Pink arrowheads mark circular forespores, and the green arrowhead marks an instance of bearding. Bars, 500 nm (B) Percentages of sporulating cells that displayed circular forespore morphology or bearding are shown based on analyses of 50 cells, except for the ΔcwlD cwlD mutant, for which the data represent analysis of 25 cells.
