Abstract
Abstract
Cells organize themselves to maintain proper shape, structure, and size during growth and division for their cellular functions. However, how these cellular organizations coordinate with the cell cycle is not well understood. This review focuses on cell morphogenesis and size of the membrane-bound nucleus in the fission yeast Schizosaccharomyces pombe. Growth polarity, an important factor for cell morphogenesis, in rod-shaped fission yeast is restricted to the cell tips and dynamically changes depending on the cell cycle stage. Furthermore, nuclear size in fission yeast is proportional to the cell size, resulting in a constant ratio between nuclear volume and cellular volume (N/C ratio). This review summarizes the signaling pathway(s) involved in growth polarity control and key factors involved in N/C ratio control and provides their roles in coordination between cell organization and the cell cycle.
