Vacuoles of Saccharomyces cerevisiae were visualized by phase-contrast microscopy. Visualization was enhanced by adding polyvinylpyrrolidone. Vacuolar segregation during the cell cycle was analysed in 42 individual cells of strain X2180 by time-lapse photomicrography. Within 15 min of bud emergence, more than 80% of the cells contained a vacuolar segregation structure in the form of either a tubule or an alignment of vesicles. The structure emerged from one point of the mother vacuole, then elongated and moved into the bud in a few minutes. The vacuolar segregation structure disappeared, usually within 20 min, before nuclear migration, leaving a separate vacuole in the bud. To test the generality of this observation several strains were grown in the presence of the vacuolar vital dye fluorescein isothiocyanate. The bud size was used to measure progress in the cell cycle. All strains formed vacuolar segregation structures in cells with small buds, although with variations in duration and timing in the cell cycle. In the presence of nocodazole vacuolar segregation occurred normally, thus, microtubules seem not to be essential in this process.
