Yeast Mitochondria Visualized in vivo using Green Fluorescent Protein. Brought to you by Wallace Marshall and Jodi Nunnari. 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. See also time-Lapse View of glancing section illustrating mitochondrial fusion and fission and time-resolved imaging reveals that the mitochondrial network is constantly undergoing breakage and fusion. This is likely to play a role in mitochondrial inheritance. From here, nice animations.
