Figure 9
(a) Region (B): the image shows a phase reconstruction using the CTF-based reconstruction of the B. thuringiensis sample. The scale bar denotes 2 µm. (b) Region (C) of (a) but at higher magnification. Note that the density of the core of the endospore (3) appears slightly higher than the outer part. The electron-dense feature (black arrow head) on the right-hand side of the spore (3) is probably a BT crystal, as the cell already includes one endospore. The scale bar denotes 1 µm. In both images the labelling is the same as in Fig. 7 ![]() |
