Morphogenesis of the Fission Yeast Cell through Cell Wall Expansion
The shape of walled cells such as fungi, bacteria, and plants are determined by the cell wall. Models for cell morphogenesis postulate that the effects of turgor pressure and mechanical properties of the cell wall can explain the shapes of these diverse cell types. However, in general, these models await validation through quantitative experiments. Fission yeast Schizosaccharomyces pombe are ro...
متن کاملRegulation of Fission Yeast Morphogenesis by PP2A Activator pta2
Cell polarization is key for the function of most eukaryotic cells, and regulates cell shape, migration and tissue architecture. Fission yeast, Schizosaccharomyces pombe cells are cylindrical and polarize cell growth to one or both cell tips dependent on the cell cycle stage. Whereas microtubule cytoskeleton contributes to the positioning of the growth sites by delivering polarity factors to th...
متن کاملHow Fission Yeast Fission in the Middle
In fission yeast, we propose that the division plane may be positioned by the position of the premitotic nucleus, perhaps by a signal emanating from the nucleus. Gene products involved in the assembly of the ring and its temporal and spatial controls are beginning to be characterized. Some of these, such as mid1p, may be involved in signals that position the division site. In animal cells, the ...
متن کاملActin cables and the exocyst form two independent morphogenesis pathways in the fission yeast
Cell morphogenesis depends on polarized exocytosis. One widely held model posits that long-range transport and exocyst-dependent tethering of exocytic vesicles at the plasma membrane sequentially drive this process. Here, we describe that disruption of either actin-based long-range transport and microtubules or the exocyst did not abolish polarized growth in rod-shaped fission yeast cells. Howe...
متن کاملThe fission yeast microtubule cytoskeleton.
The Schizosaccharomyces pombe genome sequencing project (http://www. sanger.ac.uk/Projects/S_pombe/) is nearly complete, and this is likely to generate interest in fission yeast as a model system beyond its traditional strongholds in the study of the cell cycle and sexual differentiation. In many fields S. pombe will offer a useful complement to the more widely studied Saccharomyces cerevisiae,...
