FIGURE 3.

Sporulation phenotype of mutants bearing individual exo gene deletions. Vegetative cells from WT (wt; DK1622), ΔexoC (PH1261), ΔnfsA–H (Δnfs; PH1200), ΔexoB (PH1303), ΔexoD (PH1304), ΔexoE (PH1265), ΔexoF (PH1507), ΔexoG (PH1508), ΔexoH (PH1264), ΔexoI (PH1511), and ΔMXAN_1305 (PH1509) were induced (induc) for sporulation with glycerol and examined by differential interference contrast (DIC) and phase microscopy at the indicated hours. Bar, 2 μm. The sporulation efficiency after 24 h of induction is displayed in white text (24-h phase pictures) as the average and associated standard deviation of three biological replicates.
