Three-Dimensional View as a stereo pair Scale Bar 2.0 microns

3D imaging reveals that the mitochondrion of yeast forms a connected, reticular structure associated with the cell cortex



Time-Lapse View of glancing section illustrating mitochondrial fusion and fission.

time-resolved imaging reveals that the mitochondrial network is constantly undergoing breakage and fusion. This is likely to play a role in mitochondrial inheritance.
