Many readers seem to agree with us that publication of topical volumes is a worthwhile alternative to periodic compilations of rather unrelated, though up-to-date reviews. Production of topical volumes is however, plagued with one great difficulty, that of "author synchronization". This difficulty explains the lag between volumes 1 and 2 of the series. Nevertheless we hope that the present volume will be appreciated as a valuable source of information on its central topic: How do cell organelles originate, and what mechanisms assure their continuity?

Download or read book Endosymbiotic Theories of Organelles Revisited written by Naoki Sato and published by Springer Nature. This book was released on 2020-01-03 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book re-examines the endosymbiotic theory, and presents various related theories and hypotheses since the first proposal in 1905 by a Russian biologist. It also demonstrates that Lynn Margulis’s contribution to the current endosymbiotic is less than sometimes thought, and presents a plausible idea on how the organelles were formed. Explaining that Margulis’s initial work did not intend to show the endosymbiotic origin of chloroplasts and mitochondria, the book discusses their endosymbiotic origin in the light of current biology with the help of clear visual images. Further, by including numerous historical facts and details of phylogenetic analyses using recent genomic data that are largely unknown to many in the field, it offers deep insights into the history of biology, phylogenetic analysis, and the new evolutionary thinking. 2017 was the 50-year anniversary of Margulis’s first paper in the Journal of Theoretical Biology, and 2020 will mark 50 years since the publication her famous work Origin of Eukaryotic Cells, and as such this book offers a timely reconsideration ofthe works of Lynn Margulis and the endosymbiotic origin of organelles.

Download or read book The Histogenesis of the Spinal Ganglia written by Ennio Pannese and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present review is based on the data of the literature, and on the personal experience gained by the author in recent years by studying the histogenesis of spinal ganglia. Probably, the reader will find more than one gap in the biblio graphy. The author would like to point out that in no case are such gaps due to the voluntary omission of any information, interpretations, or views. The gaps are due only to the difficulties met in trying to master such a vast literature consisting of so many contributions which have appeared over more than a century. An endeavour has been made to report not only the morphological data, but also, whenever possible, information derived from histochemical and biochemical studies. 11. Origin 01 the Spinal Ganglia Before 1868 it was generally thought (see, e.g., Remak, 1851; Bidder and Küpffer, 1857) that the spinal ganglia arise from the mesoblast of the protoverte brae (old term for somites). In 1868 His showed that the nerve cells of the spinal ganglia take their origin from the ectoderm, and more precisely from a thin band of ectoderm (Zwischenstrang, neural crest) flanking each side of the neural plate (Fig. 1 a) and interposed between it and the somatic ectoderm (Hornblatt). On this subject His (1879) wrote in a later paper " ... die spinalen Ganglien ... aus einem schmalen Substanz streifen hervorgehen, welche zwischen der Medullarplatte und dem Hornblatte gelegen ist und dessen Material ich als Zwischenstrang bezeichnet habe."
Download or read book The Golgi Apparatus written by W.G. Whaley and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive review of the Golgi apparatus and its functioning would require a multi-volume publication and not a monograph and it would be so repetitious as to discourage the reader. The requirement at this stage is for a reinterpretation of the character and functioning of this organelle since the last major interpretations have concentrated on its role in secretion and it has now been shown to be a component of essentially all cells whether or not they have been traditionally emphasized as secreting cells. As a conse quence the efforts have been placed on the common characteristics of the organelle, a postulate concerning its functioning in cells generally, and the details of variations where these seem important. The major acknowledgment of assistance in compiling the material must go to the investigators whose contributions, sometimes positive and sometimes of a character to spur additional investigations, allowed the development of this postulate. The paper has been prepared with the detailed assistance of Dr. MARIANNE DAUWALDER who, by her own studies and her insight into the significance of other studies, has been a working partner of many years in the development of a general hypothesis and whose knowledge of investiga tions of the Golgi apparatus is great enough to let her call attention to instances of support and contention with the general functional hypothesis that has been involved.

Download or read book Germ Line Soma Differentiation written by W. Hennig and published by Springer Science & Business Media. This book was released on 2013-06-05 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the oldest problems in developmental biology is the differentiation between germ line and somatic cells. The continuity of germ line cells between subsequent generations of multicellular organisms was first suggested by Owen, and later elaborated by A. Weismann to his famous germ line theory. His additional assumption that cellular differentiation was based on a differential representation of the genetic material in somatic cells was soon disproved. In some, apparently exceptional, cases, however, such differences in the genetic material between germ line and somatic cells were discovered. The best-known example is the nematod Ascaris. Boveri discovered and studied the fundamental differences in the karyotypes of germ line and soma of Parascaris equorum. Later, similar situations were found in some other organisms. However, in particular the work ofSpemann demonstrated that cellular differentiation in general is not accompanied by fundamental changes of the genetic material. Subsequently, the relatively few examples of germ line-soma differences achieved by chromatin elimination processes have been considered as a curiosity. Experimental studies have been essentially restricted to Ascaris species and to the pioneering cytological studies of chromatin elimination by S. Beermann. Despite the large proportions of the genome involved in chromatin elimina tion, our knowledge of this process is still very restricted. In particular the biological meaning of this differentiation process is entirely obscure. In this context one must, however, consider that also for the majority of DNA sequences in eukaryotic genomes the biological relevance is unclear.
Download or read book Centrosomes in Development and Disease written by Erich A. Nigg and published by John Wiley & Sons. This book was released on 2006-01-24 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discovered over a century ago, the centrosome is the major microtubule organizing center of the animal cell. It is a tiny organelle of surprising structural complexity. Over the last few years our understanding of the structure and composition of centrosomes has greatly advanced, and the demonstration of frequent centrosome anomalies in most common human tumors has sparked additional interest in the role of this organelle in a broader scientific community. The centrosome controls the number and distribution of microtubules - a major element of the cell cytoskeleton - and hence influences many important cellular functions and properties. These include cell shape, polarity, and motility, as well as the intracellular transport and positioning of various organelles. Of particular interest, centrosome function is critical for chromosome segregation and cell division. This book is meant to summarize our current knowledge of the structure, function and evolution of microtubule organizing centers, primarily centrosomes. Emphasis is on the role of these organelles in development and disease (particularly cancer).

This book was released on 2013-11-11 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thus far in the history of biology, two, and only two, fundamental principles have come to light that pervade and unify the entire science-the cell theory and the concept of evolution. While it is true that recently opened fields of inves tigation have given rise to several generalizations of wide impact, such as the universality of DNA and the energetic dynamics of ecology, closer inspection reveals them to be part and parcel of either of the first two mentioned. Because in the final analysis energy can act upon an organism solely at the cellular level, its effects may be perceived basically to represent one facet of cell me tabolism. Similarly, because the DNA theory centers upon the means by which cells build proteins and reproduce themselves, it too proves to be only one more, even though an exciting, aspect of the cell theory. In fact, if the matter is given closer scrutiny, evolution itself can be viewed as being a fundamental portion of the cell concept, for its effects arise only as a consequence of changes in the cell's genetic apparatus accumulating over geological time. Or, if one wishes, the diametrically opposite standpoint may be taken. For, if current concepts of the origin of life hold any validity, the evolution of precellular organisms from the primordial biochemicals must have proceeded over many eons of time prior to the advent of even the most primitive cell.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Comparative Physiology and Biochemistry, Volume 6, presents three papers linked by their relevance to comparative neurophysiology. The first paper on high-frequency hearing in mammals examines the sensitivity to, production, and behavioral utilization of high-frequency sound for a wide range of mammals from bats, rodents, whales, dolphins, and seals to the insectivores, primates, edentates, and carnivores. The second paper examines axonal flow and fast transport in nerves. Special attention is given to the differences in substrate and mechanism in slow and fast transport. The neuron is presented as a suitable cell type for the investigation of intracellular transport in general. The third paper on the secretory activity of neurons and related electrical activity presents a comparative assessment of all ""neurocrine"" activities, including those in the service of neuroendocrine coordination or of synaptic transmission of information. Special attention is given to the nature of vesicles containing the neurosecretions and transmitter substances and to the mechanisms of release. The electrical events accompanying such neurocrine activities are discussed.
