FIGURE 2

Cryo-ET of vegetative, sporulating, and germinating Streptomyces. Tomographic slices through S. albus at different growth stages corresponding to (A) vegetative hyphae, (B) aerial hyphae formation during early sporulation, (C) septa formation during early sporulation, (D) spore maturation, (E) release of mature spores, and (F) germination. Cytoplasmic membrane (CM) is shown in red. Vegetative peptidoglycan (PG) and spore wall (SW) are shown in green. Rodlet ultrastructure and spore coat are shown in pink and dark purple, respectively. Each tomographic slice is 20-nm thick. Scale bar = 200 nm.
