Download or read book Understanding Symmetry Breaking in Biology written by Roman Florence and published by Hayle Medical. This book was released on 2023-09-19 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In biology, symmetry breaking refers to the process of breaking of uniformity or reducing the number of points to view invariance in order to produce a more improbable and structured state. It occurs when symmetry with a specific axis is lost in order to create polarity. This polarity helps the biological system in differentiating between different poles along an axis. Cells must first establish polarity by a symmetry-breaking event, before organs and tissues become polar. The fact that symmetry breaking occurs at all scales reflects its importance in biology. It can be found at the subcellular level, macromolecular level, and even at the organ and tissue levels. This book provides significant information to help develop a good understanding of symmetry breaking in biology. It presents researches and studies performed by experts across the globe. Those in search of information to further their knowledge will be greatly assisted by this book.
Download or read book Symmetry In Plants written by Denis Barabe and published by World Scientific. This book was released on 1998-03-26 with total page 888 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with biological, mathematical, descriptive, causal and systemic phyllotaxis. It aims at reflecting the widest possible range of ideas and research closely related to phyllotaxis and contains 30 well illustrated chapters.The book has three parts of equal importance. The first two parts concern data collecting, pattern recognition and pattern generation to which students of phyllotaxis are well accustomed. The third part is devoted to the problem of origins of phyllotactic patterns, giving the field of phyllotaxis the universality it requires to be fully understood.Phyllotaxis-like patterns are found in places where genes are not necessarily present. Part III concerns general comparative morphology, homologies with phyllotactic patterns, and recent trends on evolution that can help to understand phyllotaxis.The distinguished researchers who accepted to participate in the production of this book, strongly contributed to the field of phyllotaxis in the past and have devoted a lot of their time to the fascinating subject coming up with most valuable findings, or are newcomers with original ideas that may be very relevant for the future of the field. The book summarizes and updates their contributions, and promotes new avenues in the treatment of phyllotaxis.This book on mathematical and biological phyllotaxis is the first collective book ever. A landmark in the history of phyllotaxis.
Download or read book An E cadherin and PAR 3 based Symmetry Breaking Mechanism Translates Stable Cell cell Contacts Into Coordinate Tissue Polarity in C Elegans Intestinal Epithelial Cells written by Victor Frank Naturale and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tissue-wide patterning is essential to multicellular development, requiring cells to individually generate polarity axes and coordinate them in space and time with neighbors. One of the most prevalent animal tissues are epithelia, which polarize along a characteristic apico-basolateral axis and are critical for protecting internal organs from the external environment. The mechanisms which 'break symmetry' and inform the orientation and execution of apico-basolateral polarity axes across diverse epithelia remain poorly understood. To address these questions, I explored symmetry breaking in the developing Caenorhabditis elegans intestine, a simple epithelial tube which gains its polarity as a sixteen-celled primordium when apical proteins polarize along a central embryonic midline. After introducing general principles of epithelial polarity (Chapter 1) and development of the worm intestine (Chapter 2), I describe essential roles I found for the polarity scaffold PAR-3 and the transmembrane adhesion protein HMR-1/E-cadherin in epithelial symmetry breaking (Chapter 3). C. elegans intestinal cells break their symmetry as an 8-celled primordium when they localize PAR-3 and HMR-1 into large puncta I term Local Polarity Complexes (LPCs). By pairing detailed imaging approaches with powerful genetic tools to remove LPC components specifically in the intestine, I discovered that PAR-3 and HMR-1 function as an interdependent module to build LPCs during, but that these factors diverge in function to elaborate tissue polarity. In Chapter 4, I describe how asymmetric information is transmitted to intestinal cells to mark the first meaningful polarity cue within the tissue. I found that LPCs mature exclusively at homotypic (intestine/intestine) contacts and are largely absent from heterotypic (intestine/neighbor) contacts. Through careful analysis of high temporal resolution developmental movies and acute perturbations with chemical inhibitors, I showed that symmetry breaking is mediated by inherent differences in contact stability: LPCs can form at all intestinal surfaces but are systematically removed from heterotypic contacts via neighbor rearrangements and oriented cell division. This work reveals a novel 'molecule-agnostic' symmetry breaking paradigm for an internally developing epithelium. Finally, I demonstrate the existence of backup mechanisms which eventually polarize intestinal primordia which lack HMR-1 (Chapter 5), and describe a proof-of-concept forward genetic screening approach to reveal interactors working in concert with or parallel to HMR-1.

Download or read book Cytokinesis in Animal Cells written by R. Rappaport and published by Cambridge University Press. This book was released on 2005-09-08 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book traces the history of some of the major ideas in the field and gives an account of our current knowledge of animal cytokinesis. It contains descriptions of division in different kinds of cells and the proposed explanations of the mechanisms underlying the visible events. The author also describes and explains experiments devised to test cell division theories. The forces necessary for cytokinesis now appear to originate from the interaction of linear polymers and motor molecules that have roles in force production, motion and shape change that occur in other phases of the biology of the cell. The localization of the force-producing mechanism to a restricted linear part of the subsurface is caused by the mitotic apparatus, the same cytoskeletal structure that insures orderly mitosis.

Download or read book Introductory Biomechanics written by C. Ross Ethier and published by Cambridge University Press. This book was released on 2007-03-12 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introductory Biomechanics is a new, integrated text written specifically for engineering students. It provides a broad overview of this important branch of the rapidly growing field of bioengineering. A wide selection of topics is presented, ranging from the mechanics of single cells to the dynamics of human movement. No prior biological knowledge is assumed and in each chapter, the relevant anatomy and physiology are first described. The biological system is then analyzed from a mechanical viewpoint by reducing it to its essential elements, using the laws of mechanics and then tying mechanical insights back to biological function. This integrated approach provides students with a deeper understanding of both the mechanics and the biology than from qualitative study alone. The text is supported by a wealth of illustrations, tables and examples, a large selection of suitable problems and hundreds of current references, making it an essential textbook for any biomechanics course.

Download or read book Asymmetry in Plants written by Bir Bahadur and published by CRC Press. This book was released on 2019-03-25 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants exhibit forms of asymmetry analogous to "handedness" in bilaterally symmetrical animals. This book explores the evolutionary significance and development of asymmetry. Examples of genetic control include the direction of tendril or stem coiling of many climbing plants; the so-called spiral phyllotaxy and floral taxy; and contorted petal arrangement is another kind of left- right symmetry in plants; the direction of contortion is fixed in some but not in other plants. The book will underscore tha all phenomena related to handedness start during embryogenesis itself, with the occurrence of embryo rotation. Key selling features: First consolidated book on Plant Handedness Relates handedness, asymmetry and chirality to the evolution of different organizational levels in plant biology Emphasizes handedness as a vital governing force in plant functional evolution Provides a new perspective, hitherto ignored, into plant developemtn and evolution Describes how an age-old phenomenon can give scope for investigation from a very modern interdisciplinary approach
Download or read book Perspectives on Organisms written by Giuseppe Longo and published by Springer Science & Business Media. This book was released on 2013-12-13 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: This authored monograph introduces a genuinely theoretical approach to biology. Starting point is the investigation of empirical biological scaling including their variability, which is found in the literature, e.g. allometric relationships, fractals, etc. The book then analyzes two different aspects of biological time: first, a supplementary temporal dimension to accommodate proper biological rhythms; secondly, the concepts of protension and retention as a means of local organization of time in living organisms. Moreover, the book investigates the role of symmetry in biology, in view of its ubiquitous importance in physics. In relation with the notion of extended critical transitions, the book proposes that organisms and their evolution can be characterized by continued symmetry changes, which accounts for the irreducibility of their historicity and variability. The authors also introduce the concept of anti-entropy as a measure for the potential of variability, being equally understood as alterations in symmetry. By this, the book provides a mathematical account of Gould's analysis of phenotypic complexity with respect to biological evolution. The target audience primarily comprises researchers interested in new theoretical approaches to biology, from physical, biological or philosophical backgrounds, but the book may also be beneficial for graduate students who want to enter this field.
