Cell wall growth during the cell cycle of Schizosaccharomyces pombe

Cell wall growth of an asynchronous culture of Schizosaccharomyces pombe was studied by fluorescence microscopy and time‐lapse cinematography. The cell wall growth of individual cells is a time‐ordered process which can be divided into 4 stages: post‐division stage, stage of growth initiation, stage of extension growth, and constant length stage. Different aspects of these stages are discussed. During the exponential phase of growth the population has a rather stable structure from the point of view of division scar numbers. The significance of the division scars for the study of cell wall growth and multiplication is discussed.
