Colcemid-resistant mutants of fission yeast have an altered cell cycle.
Cell-cycle progression is altered in some colcemid-resistant mutants of fission yeast. The duration of particular stages of the cell cycle is different but total doubling time is unchanged from that of wild type. Cell-plate formation is prolonged relative to wild type but concomitant DNA synthesis is not affected. Separation of daughter cells is inhibited in some strains, giving rise to unusual cell morphologies. Control of cell division is altered in two ways: Critical size for division is increased. The probability of division a function of size is decreased.
