Density fluctuation during the cell cycle in the defective vacuolar morphology mutants of Saccharomyces cerevisiae.

Abstract excerpt

The buoyant densities of the yeast cells of defective vacuolar morphology mutants were examined by equilibrium sedimentation centrifugation in a Percoll density gradient. These vacuoleless mutants also show density fluctuation as wild-type cells during the cell cycle. This suggests that morphological changes of the vacuole are not related to cyclic density fluctuation in Saccharomyces cerevisiae.
