Fluorescence staining of mitochondria for morphology analysis in Saccharomyces cerevisiae.
Mitochondria are highly dynamic organelles in all eukaryotic cells. Most of our insights regarding the mechanisms that determine the morphogenesis and motility of mitochondria have been identified and analyzed first in the model organism Saccharomyces cerevisiae. To this end high-resolution microscopic methods were applied that rely on fluorescence labeling of the organelle. A comprehensive overview of fluorescence staining approaches that were successfully applied to study the behavior of mitochondria in vivo but also in fixed cells is provided. Slightly modified versions of the methods described here can also be used to analyze other compartments of the yeast cell. Microscopic setups and imaging methods will only be shortly discussed since these are highly dependent on each laboratory's basic infrastructure.
