Cell Shape and Cell Division in Fission Yeast
The fission yeast Schizosaccharomyces pombe has served as an important model organism for investigating cellular morphogenesis. This unicellular rod-shaped fission yeast grows by tip extension and divides by medial fission. In particular, microtubules appear to define sites of polarized cell growth by delivering cell polarity factors to the cell tips. Microtubules also position the cell nucleus...
متن کاملDynamic positioning of the fission yeast cell division plane.
A key question in cytokinesis is how the cell division plane is positioned. Whereas microtubules of the mitotic apparatus specify the division site in animal cells, we show here that the nucleus plays this role in the fission yeast Schizosaccharomyces pombe. By centrifuging cells to move the nucleus, we find that the nucleus (or a nuclear-associated structure) actively influences the position o...
متن کاملMathematical model of the cell division cycle of fission yeast.
Much is known about the genes and proteins controlling the cell cycle of fission yeast. Can these molecular components be spun together into a consistent mechanism that accounts for the observed behavior of growth and division in fission yeast cells? To answer this question, we propose a mechanism for the control system, convert it into a set of 14 differential and algebraic equations, study th...
متن کاملDikaryotic cell division of the fission yeast Schizosaccharomyces pombe.
Dikaryons, cells with two haploid nuclei contributed by the members of a mating pair, are part of the life cycle of many filamentous fungi, but the molecular mechanisms underlying the division of dikaryons are largely unknown. We found that the fission yeast Schizosaccharomyces pombe has a latent ability to divide as a dikaryon. Cells capable of restarting the mitotic cycle with two nuclei were...
متن کاملCell migration and division in amoeboid-like fission yeast
Yeast cells are non-motile and are encased in a cell wall that supports high internal turgor pressure. The cell wall is also essential for cellular morphogenesis and cell division. Here, we report unexpected morphogenetic changes in a Schizosaccharomyces pombe mutant defective in cell wall biogenesis. These cells form dynamic cytoplasmic protrusions caused by internal turgor pressure and also e...
