The shift of a synchronous culture of the fission yeast, Schizosaccharomyces pombe, from a poor to a rich medium resulted in division delay. The mean time period from the shift till division was nearly constant, regardless of the time of shift in the cell cycle.
The time period from the shift till division of the individual cells was negatively proportional to cell size at the shift. The division size of the shifted cells was larger than that of exponentially proliferating cells. From these results, the dependence of the timing of division on cell size at the shift, not at division, is discussed.
