Abstract

The kinetics of cell proliferation of a population of a small-size mutant of were compared with those of a wild-type cell population, using time-lapse cinephotomicrography. The mean size of small-size mutant cells was approximately half that of wild-type cells at corresponding points in the cell cycle. The cycle times of small-size mutant cells were much more variable, especially for daughter cells, than those of wild-type cells. The difference in the variability of cycle times of the two strains was mainly due to the different degree of variability of their respective unbudded periods. Like wild-type cells, daughter cells of the small-size mutant were smaller and had a longer cycle time than parent cells. The small-size mutant retains a single size control over the cell cycle.
