This book was released on 2013-04-17 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: Actin is an extremely abundant protein that comprises a dynamic polymeric network present in all eukaryotic cells, known as the actin cytoskeleton. The structure and function of the actin cytoskeleton, which is modulated by a plethora of actin-binding proteins, performs a diverse range of cellular roles. Well-documented functions for actin include: providing the molecular tracks for cytoplasmic streaming and organelle movements; formation of tethers that guide the cell plate to the division site during cytokinesis; creation of honeycomb-like arrays that enmesh and immobilize plastids in unique subcellular patterns; supporting the vesicle traffic and cytoplasmic organization essential for the directional secretory mechanism that underpins tip growth of certain cells; and coordinating the elaborate cytoplasmic responses to extra- and intracellular signals. The previous two decades have witnessed an immense accumulation of data relating to the cellular, biochemical, and molecular aspects of all these fundamental cellular processes. This prompted the editors to put together a diverse collection of topics, contributed by established international experts, related to the plant actin cytoskeleton. Because the actin cytoskeleton impinges on a multitude of processes critical for plant growth and development, as well as for responses to the environment, the book will be invaluable to any researcher, from the advanced undergraduate to the senior investigator, who is interested in these areas of plant cell biology.
Download or read book The Cytoskeleton written by Vaidurya Pratap Sahi and published by Springer. This book was released on 2020-12-10 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the plant cytoskeleton and its various cross-talks with other cellular components leading to its role in plant growth and development. It not only allows the geometric and signaling dimensions of cells, but is also very important in physiological processes. The book discusses the recent studies showing the role of actin and microtubule cytoskeleton interactions in cell-wall assembly and dynamics. The authors examine the role of both microtubules in the mechanics of plant cells, and actin filaments in the motility of chloroplasts. Based on recent advances in the study of the acto-myosin complex using high-resolution microscopy, they propose a new model for intracellular transport in plants. Exploring an almost-forgotten field of bioelectricity in the context of the cytoskeleton, the book highlights connections between the dynamic actin filaments and the bioelectricity of membranes and demonstrates that the plant cytoskeleton is involved in the distribution of plant hormones. Lastly, it addresses the role of endomembrane -cytoskeleton interactions to show the importance of the cytoskeleton in organelle morphogenesis and cellular functions. Studies in various plant models have shown how the actin filament and microtubules control and coordinate plant cell growth and development. This book summarizes the mechanisms underlying these functions.
Download or read book The Actin Cytoskeleton written by Brigitte M. Jockusch and published by Springer. This book was released on 2017-01-03 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Actin is one of the most abundant proteins and ubiquitously expressed in all eukaryotes. In recent years, the analysis of structure and function of such complexes has shed new light on actin's role in cellular and tissue morphogenesis, locomotion and various forms of intracellular motility, but also on its role in nuclear processes like chromatin architecture and transcription. Progress in understanding these different physiological phenomena, but also in unravelling the basis of actin-based pathophysiological processes has been made by combining video microscopy, molecular biology, genetics and biochemistry. Thus, the current research on actin, as ongoing in many international laboratories, is a "hot spot" in basic and translational research in life sciences. In this book on "The Actin Cytoskeleton", twelve internationally renowned authors present specific chapters that cover their recent work concerned with the various roles of actin mentioned above. This comprehensive volume is therefore an attractive handbook for teachers and students in many fields of medicine and pharmacology.
Download or read book The Plant Cytoskeleton written by Bo Liu and published by Springer Science & Business Media. This book was released on 2010-11-23 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant cells house highly dynamic cytoskeletal networks of microtubules and actin microfilaments. They constantly undergo remodeling to fulfill their roles in supporting cell division, enlargement, and differentiation. Following early studies on structural aspects of the networks, recent breakthroughs have connected them with more and more intracellular events essential for plant growth and development. Advanced technologies in cell biology (live-cell imaging in particular), molecular genetics, genomics, and proteomics have revolutionized this field of study. Stories summarized in this book may inspire enthusiastic scientists to pursue new directions toward understanding functions of the plant cytoskeleton. The Plant Cytoskeleton is divided into three sections: 1) Molecular Basis of the Plant Cytoskeleton; 2) Cytoskeletal Reorganization in Plant Cell Division; and 3) The Cytoskeleton in Plant Growth and Development. This book is aimed at serving as a resource for anyone who wishes to learn about the plant cytoskeleton beyond ordinary textbooks.

Download or read book The Plant Cytoskeleton a Key Tool for Agro Biotechnology written by Yaroslav B. Blume and published by Springer Science & Business Media. This book was released on 2008-10-23 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essential processes in biology such as cell and nuclear division, development, intracellular transport and physiological response, rely on the perception of environmental and intracellular signals and their transduction to subcellular targets. The mechanisms by which these signals are received by cells and transduced towards the proper targets by cytoskeletal components constitute one of the most important and rapidly developing areas in modern plant biology. In addition, fundamentally important responses of plants to biotic and abiotic factors also involve signalling to and through the cytoskeleton, which helps explain the current interest of biotechnology in this field of fundamental research. Manipulation of cytoskeletal components, the microtubules and microfilaments, had, until recently, not been a priority issue for plant biotechnology. However, given the fundamental role of the cytoskeleton during plant growth and development, the potential for biotechnological applications is immense. The NATO Advanced Research Workshop, “The Plant Cytoskeleton: Genomic and Bioinformatic Tools for Biotechnology and Agriculture” was held in Yalta, Ukraine, from September 19 to 23, 2006 – which continued the tradition of the first two International Symposia “Plant Cytoskeleton: Molecular Keys for Biotechnology” (Yalta, Ukraine, 1998) and “The Plant Cytoskeleton: functional diversity and biotechnological implications” (Kiev, Ukraine, 2002).
Download or read book Integrated G Proteins Signaling in Plants written by Shaul Yalovsky and published by Springer Science & Business Media. This book was released on 2009-11-25 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on the structure, function and regulation of plant signaling G proteins and their function in hormonal pathways, polarity, differentiation, morphogenesis and responses to biotic and abiotic stresses. Plants are sessile organisms that need to continuously coordinate between external and internal cues. This coordination requires the existence of hubs to allow cross-talk between different signaling pathways. A single family of Rho GTPases, termed either ROPS or RACs, and heterotrimeric G proteins have emerged as the major molecular switches in a multitude of signal transduction pathway in plants.
Download or read book The Actin Cytoskeleton and the Regulation of Cell Migration written by Jonathan M. Lee and published by Biota Publishing. This book was released on 2013-06-01 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mammalian cytoskeleton is an internal framework of actin, tubulin, and intermediate filament proteins. Proteins of these three classes assemble non-covalently into filamentous polymers that support the structural integrity of the relatively fragile lipid plasma membrane. In addition, cytoskeletal polymers provide the mechanical strength that hold a cell together and anchor it to its growth substrate. The cytoskeleton must also have the capacity for rapid and substantial remodeling and provide the motive and tractor force necessary to drive motility. As such, the cytoskeleton has a functional duality: sufficiently rigid to prevent plasma membrane deformation but pliable enough to allow for cytokinesis; sufficiently adhesive to allow for traction but dynamic enough to allow movement from one place to another. A major research challenge in cytoskeleton biology is to understand how cytoskeletal proteins assemble and dissemble in support of physiological processes. This chapter will focus on the role of the actin cytoskeleton in cell migration. More specifically, we will focus on the actin cytoskeleton of vertebrate cells.

Download or read book Annual Plant Reviews The Plant Cytoskeleton in Cell Differentiation and Development written by Patrick J. Hussey and published by John Wiley & Sons. This book was released on 2009-02-12 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annual Plant Reviews, Volume 10 The cytoskeleton is a dynamic filamentous structure composed of at least actin and microtubule networks. Actin and microtubules are no different structurally from their animal and fungal counterparts. However, the strategies of cell differentiation and development in plants require this network to respond appropriately to plant-specific developmental cues and to environmental factors. This book views the cytoskeleton from different perspectives but, on the whole, as a network composed of structural and regulatory proteins controlled by internal and external stimuli that result in different aspects of cell differentiation. This is a volume for researchers and professionals in plant biochemistry, cell biology and genetics.

Download or read book Roots written by Jun J. Abe and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: The root is the organ that functions as the interface between the plant and the earth environment. Many human management practices involving crops, forests and natural vegetation also affect plant growth through the soil and roots. Understanding the morphology and function of roots from the cellular level to the level of the whole root system is required for both plant production and environmental protection. This book is at the forefront of plant root science (rhizology), catering to professional plant scientists and graduate students. It covers root development, stress physiology, ecology, and associations with microorganisms. The chapters are selected papers originally presented at the 6th Symposium of the International Society of Root Research, where plant biologists, ecologists, soil microbiologists, crop scientists, forestry scientists, and environmental scientists, among others, gathered to discuss current research results and to establish rhizology as a newly integrated research area.
Download or read book Mechanical Integration of Plant Cells and Plants written by Przemyslaw Wojtaszek and published by Springer Science & Business Media. This book was released on 2011-06-28 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical reactions and interactions between molecules are commonly considered the basis of life, and thus the biochemical nature of cells and organisms is relatively well recognized. Research conducted in recent years, however, increasingly indicates that physical forces profoundly affect the functioning of life at all levels of its organization. To detect and to respond to such forces, plant cells and plants need to be structured mechanically. This volume focuses on mechanical aspects of plant life. It starts with a consideration of the mechanical integration of supracellular structures and mechanical properties of cellular building blocks to show how the structural integrity of plant cells is achieved and maintained during growth and development. The following chapters reveal how the functioning of integrated plant cells contributes to the mechanical integration of plants, and how the latter are able to detect physical stimuli and to reorganize their own cells in response to them. The mechanical aspects of plant responses to stresses are also presented. Finally, all these aspects are placed in an evolutionary context.

Available in PDF, EPUB and Kindle. Book excerpt: This book discusses central concepts and theories in cell biology from the ancient past to the 21st century, based on the premise that understanding the works of scientists like Hooke, Hofmeister, Caspary, Strasburger, Sachs, Schleiden, Schwann, Mendel, Nemec, McClintock, etc. in the context of the latest advances in plant cell biology will help provide valuable new insights. Plants have been an object of study since the roots of the Greek, Chinese and Indian cultures. Since the term “cell” was first coined by Robert Hooke, 350 years ago in Micrographia, the study of plant cell biology has moved ahead at a tremendous pace. The field of cell biology owes its genesis to physics, which through microscopy has been a vital source for piquing scientists’ interest in the biology of the cell. Today, with the technical advances we have made in the field of optics, it is even possible to observe life on a nanoscale. From Hooke’s observations of cells and his inadvertent discovery of the cell wall, we have since moved forward to engineering plants with modified cell walls. Studies on the chloroplast have also gone from Julius von Sachs’ experiments with chloroplast, to using chloroplast engineering to deliver higher crop yields. Similarly, advances in fluorescent microscopy have made it far easier to observe organelles like chloroplast (once studied by Sachs) or actin (observed by Bohumil Nemec). If physics in the form of cell biology has been responsible for one half of this historical development, biochemistry has surely been the other.
Download or read book Cell Biology of Plant and Fungal Tip Growth written by Anja Geitmann and published by IOS Press. This book was released on 2001 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tip growth is a type of cellular growth that is represented in many and diverse cell types, which are important to plant breeding (pollen tubes), agriculture (root hairs) and plant and animal pathology (fungal hyphae). Also moss and fern protonemata as well as algal zygotes and yeasts exhibit the features unique for tip growth: directable apical linear growth which renders the cell able to penetrate its growth environment. In this volume various cell biological aspects of this particular growth phenomenon are discussed, such as the initiation and maintenance of an anisotropically growing cell, the function of cytoskeletal elements, extracellular matrix and turgor, the regulation of ion homeostasis, the mechanism of signalling events, and the interaction of the cell with the environment.
Download or read book Endocytosis in Plants written by Jozef Šamaj and published by Springer Science & Business Media. This book was released on 2012-10-02 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Endocytosis is a fundamental cellular process by means of which cells internalize extracellular and plasma membrane cargos for recycling or degradation. It is important for the establishment and maintenance of cell polarity, subcellular signaling and uptake of nutrients into specialized cells, but also for plant cell interactions with pathogenic and symbiotic microbes. Endocytosis starts by vesicle formation at the plasma membrane and progresses through early and late endosomal compartments. In these endosomes cargo is sorted and it is either recycled back to the plasma membrane, or degraded in the lytic vacuole. This book presents an overview of our current knowledge of endocytosis in plants with a main focus on the key molecules undergoing and regulating endocytosis. It also provides up to date methodological approaches as well as principles of protein, structural lipid, sugar and microbe internalization in plant cells. The individual chapters describe clathrin-mediated and fluid-phase endocytosis, as well as flotillin-mediated endocytosis and internalization of microbes. The book was written for a broad spectrum of readers including students, teachers and researchers.
