The evolution of the cytoskeleton [PDF]
The cytoskeleton is a system of intracellular filaments crucial for cell shape, division, and function in all three domains of life. The simple cytoskeletons of prokaryotes show surprising plasticity in composition, with none of the core filament-forming proteins conserved in all lineages.

The Bacterial Cytoskeleton [PDF]
One of the pleasures of teaching introductory biology courses is learning new things about old, familiar subjects … such as the differences between eukaryotes and prokaryotes. For a eukaryotic cell biologist, such learning usually entails examining how bacteria function, in ways other than how they replicate and transcribe DNA and how they synthesize ...

The cytoskeleton in spermatogenesis [PDF]
As germ cells progress through spermatogenesis, they undergo a dramatic transformation, wherein a single, diploid spermatogonial stem cell ultimately produces thousands of highly specialised, haploid spermatozoa. The cytoskeleton is an integral aspect of all eukaryotic cells.

The cytoskeleton and disease [PDF]
AbstractCytoskeletal research in recent years has revolutionized cell biology and biomedicine. The cytoskeleton spans the cytoplasm and interconnects the cell nucleus with the extracellular matrix, thereby forming a structural link between molecules involved in cell communication on the one hand, and gene expression on the other. Since the cytoskeleton

Evolution of the cytoskeleton [PDF]
AbstractThe eukaryotic cytoskeleton appears to have evolved from ancestral precursors related to prokaryotic FtsZ and MreB. FtsZ and MreB show 40–50% sequence identity across different bacterial and archaeal species. Here I suggest that this represents the limit of divergence that is consistent with maintaining their functions for cytokinesis and cell ...

AbstractNot only eukaryotes, but also prokaryotes possess a cytoskeleton. Tubulin‐related bacterial protein FtsZ, and actin‐related bacterial proteins MreB/Mbl have recently been described as constituents of bacterial cytoskeletons. Genes coding for MreB/Mbl could only be found in elongated bacteria, not in coccoid forms.

ON THE ROLE OF THE CYTOSKELETON IN COCCOLITH MORPHOGENESIS: THE EFFECT OF CYTOSKELETON INHIBITORS1 [PDF]
The coccolithophore Emiliania huxleyi (Lohmann) W. W. Hay et H. Mohler was cultured in natural seawater with the addition of either the microtubule‐inhibitor colchicine, the actin‐inhibitor cytochalasin B, or the photosynthesis inhibitor 3‐(3,4 dichlorophenyl)‐1,1‐dimethyl‐urea (DCMU). Additionally, E.

Cytoskeleton: Centrosom-in absentia [PDF]
Recent results challenge long-held assumptions that centrosomes are essential organizers of mitotic spindles, but suggest that they couple spindle behavior with developmental and cellular events, perhaps by nucleating astral microtubules which mediate interactions with other cytoskeletal components.

Hormones and the Cytoskeleton [PDF]
THE object of this communication is to present the hypothesis that hormones modify the ‘cytoskeleton’ of the cell. Though I have held this view for some time, and have discussed it with others, I have not advanced it formally, because until now it did not appear to be useful.
