Calcium is thought to be involved in regulating mitotic transitions. The basis for this view is set out. Recent data from experiments on sea urchin embryos is discussed. The relative simplicity of the embryonic cell cycle and the relative ease with which cell physiology can be done in sea urchin embryos has allowed the clear demonstration that the ...

Publisher Summary This chapter discusses the ultrastructure of vegetative nuclear division, that is, mitosis in fungi and closely related groups. Mitotic divisions occurring in the vegetative phase of the fungi are essentially the same as in higher organisms, although the details are frequently obscured by the small size of the nuclei.

IN the ascus of Neurospora, meiosis and mitosis appear to resemble those in higher plants1–4. However, within the mycelium of Neurospora and of a number of other fungi, some observers report that the conventional stages of nuclear division are lacking, that the spindle is absent, and that the nuclei divide by becoming constricted and pulling in two5–8.

Mitosis controls the Golgi and the Golgi controls mitosis
Current Opinion in Cell Biology, 2007In mammals, the Golgi complex is structured in the form of a continuous membranous system composed of up to 100 stacks connected by tubular bridges, the 'Golgi ribbon'. During mitosis, the Golgi undergoes extensive fragmentation through a multistage process that allows its correct partitioning and inheritance by daughter cells.

Although normal mitosis is characterized by the regular alternation of chromosome reproduction and segregation of daughter chromosomes, the two processes are not necessarily correlated, and their relationship can be changed in different ways (cf. Oksala, 1954).

The mitotic spindle is a fascinating protein machine that uses bipolar arrays of dynamic microtubules and many mitotic motors to coordinate the accurate segregation of sister chromatids. Here we discuss recent mathematical models and computer simulations that, in concert with experimental studies, help explain the molecular mechanisms by which the ...

Publisher Summary This chapter discusses the structure and composition of the mitotic apparatus in relation to Ca regulation and describes the existence, timing, and location of endogenous Ca transients. The evidence for the role of Ca gathered from the experimental modulation of the extracellular and intracellular environments is also presented in ...

The mitotic chromosome movements are discussed in relation with recent studies on tubulins, their assembly and disassembly, and the associated proteins. The role of contractile proteins in the mitotic spindle is considered, and also that of the calcium regulating protein (CDR) which has been demonstrated recently in the mitotic spindle.

Publisher Summary The term ‘biomorph” is a name given to a computer graphic representation that resembles a biological morphology.Biomorphs look like simple lifeforms, and the natural extension of the biomorph would obviously be their reproduction and cell division. This chapter presents an informal computer graphics investigation of biomorphs.
