Video 1. Tomographic reconstruction of Golgi cisternae in an untreated cell. .
Yeast cells were analyzed by STEM tomography as described in Figure 8. The first third of the movie shows every tenth tomographic slice. The second third of the movie shows the same tomographic slices after contours were traced to label early Golgi membranes green and late Golgi membranes red. The final third of the movie shows a rotation of the tomographic model. See also Figure 8A.
