Cell Size Influences the Reproductive Potential and Total Lifespan of the Saccharomyces cerevisiae Yeast as Revealed by the Analysis of Polyploid Strains

Figure 4

Changes in the size of individual yeast cells during the reproductive phase of life. Reproductive potential of the yeast strains differing in ploidy (from 1n to 4n) representing three genetic backgrounds (a) SP4, (c) BY474X, and (e) BMA64 was determined by the micromanipulation method. Changes in the cell size during the reproductive phase of yeast cell life were estimated by analysis of microscopic images recorded every fifth cell cycle during the determination of reproductive potential of (b) SP4, (d) BY474X, and (f) BMA64. Data were obtained from two independent experiments of 40 cells each.
