Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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).

Book Description
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.

Book Description
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.

Book Description
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.
