Figure 3. Cryo-correlative light and electron microscopy (cryo-CLEM) and high-pressure freezing and freeze substitution (HPF-FS) of 12-hour MI hyphae of S. coelicolor grown on GYM agar.

Figure 3

(ad) Cryo-CLEM. (a) Phase-contrast mode, (b,c) FM5-95 (red) staining, (d) electron microscopy. (e,f) HPF-FS electron microscopy, (e) cross-membrane without cell wall, (f) cross-membrane with a thick cell wall. Arrows indicate internal cross-membranes in the form of membrane vesicles and membrane arrays. Arrowheads indicate cross-membranes continuous with the extracellular membrane delimiting cellular segments. Scale bars: (a) 20 μm, (b) 5 μm, (c) 4 μm, (d) 500 nm, (e) and (f) 100 nm.
