Download or read book Diatom Gliding Motility written by Stanley A. Cohn and published by John Wiley & Sons. This book was released on 2021-09-08 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: DIATOM GLIDING MOTILITY Moving photosynthetic organisms are still a great mystery for biologists and this book summarizes what is known and reports the current understanding and modeling of those complex processes. The book covers a broad range of work describing our current state of understanding on the topic, including: historic knowledge and misconceptions of motility; evolution of diatom motility; diatom ecology & physiology; cell biology and biochemistry of diatom motility, anatomy of motile diatoms; observations of diatom motile behavior; diatom competitive ability, unique forms of diatom motility as found in the genus Eunotia; and models of motility. This is the first book attempting to gather such information surrounding diatom motility into one volume focusing on this single topic. Readers will be able to gather both the current state of understanding on the potential mechanisms and ecological regulators of motility, as well as possible models and approaches used to help determine how diatoms accomplish such varied behaviors as diurnal movements, accumulation into areas of light, niche partitioning to increase species success. Given the fact that diatoms remain one of the most ecologically crucial cells in aquatic ecosystems, we hope that this volume will act as a springboard towards future research into diatom motility and even better resolution of some of the issues in motility. Audience Diatomists, phycologists, aquatic ecologists, cellular physiologists, environmental biologists, biophysicists, diatom nanotechnologists, algal ecologists, taxonomists.

Download or read book Actin A Dynamic Framework for Multiple Plant Cell Functions written by Christopher J. Staiger and published by Springer Science & Business Media. 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book describes the unique characean experimental system, which provides a simplified model for many aspects of the physiology, transport and electrophysiology of higher plants. The first chapter offers a thorough grounding in the morphology, taxonomy and ecology of Characeae plants. Research on characean detached cells in steady state is summarised in Chapter 2, and Chapter 3 covers characean detached cells subjected to calibrated and mostly abiotic types of stress: touch, wounding, voltage clamp to depolarised and hyperpolarised potential difference levels, osmotic and saline stress. Chapter 4 highlights cytoplasmic streaming, cell-to-cell transport, gravitropism, cell walls and the role of Characeae in phytoremediation. The book is intended for researchers and students using the characean system and will also serve as an invaluable reference resource for electrophysiologists working on higher plants.
Download or read book Communication in Plants written by František Baluška and published by Springer Science & Business Media. This book was released on 2007-02-15 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant neurobiology is a newly emerging field of plant sciences. It covers signalling and communication at all levels of biological organization – from molecules up to ecological communities. In this book, plants are presented as intelligent and social organisms with complex forms of communication and information processing. Authors from diverse backgrounds such as molecular and cellular biology, electrophysiology, as well as ecology treat the most important aspects of plant communication, including the plant immune system, abilities of plants to recognize self, signal transduction, receptors, plant neurotransmitters and plant neurophysiology. Further, plants are able to recognize the identity of herbivores and organize the defence responses accordingly. The similarities in animal and plant neuronal/immune systems are discussed too. All these hidden aspects of plant life and behaviour will stimulate further intense investigations in order to understand the communicative plants in their whole complexity.

Download or read book Solute Transport in Plants written by T.J. Flowers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of solute transport in plants dates back to the beginnings of experimental plant physiology, but has its origins in the much earlier interests of humankind in agriculture. Given this lineage, it is not surprising that there have been many books on the transport of solutes in plants; texts on the closely related subject of mineral nutrition also commonly address the topic of ion transport. Why another book? Well, physiologists continue to make new discoveries. Particularly pertinent is the characterisation of enzymes that are able to transport protons across membranes during the hydrolysis of energy-rich bonds. These enzymes, which include the H + -A TPases, are now known to be crucial for solute transport in plants and we have given them due emphasis. From an academic point of view, the transport systems in plants are now appreciated as worthy of study in their own right-not just as an extension of those systems already much more widely investigated in animals. From a wider perspective, understanding solute transport in plants is fundamental to understanding plants and the extent to which they can be manipulated for agricultural purposes. As physiologists interested in the mechanisms of transport, we first set out in this book to examine the solutes in plants and where are they located. Our next consideration was to provide the tools by which solute movement can be understood: a vital part of this was to describe membranes and those enzymes catalysing transport.
Download or read book Salinity Tolerance in Plants Mechanisms and Regulation of Ion Transport written by Vadim Volkov and published by Frontiers Media SA. This book was released on 2018-01-12 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life presumably arose in the primeval oceans with similar or even greater salinity than the present ocean, so the ancient cells were designed to withstand salinity. However, the immediate ancestors of land plants most likely lived in fresh, or slightly brackish, water. The fresh/brackish water origins might explain why many land plants, including some cereals, can withstand moderate salinity, but only 1 – 2 % of all the higher plant species were able to re-discover their saline origins again and survive at increased salinities close to that of seawater. From a practical side, salinity is among the major threats to agriculture, having been one of the reasons for the demise of the ancient Mesopotamian Sumer civilisation and in the present time causing huge annual economic losses of over 10 billion USD. The effects of salinity on plants include osmotic stress, disruption of membrane ion transport, direct toxicity of high cytoplasmic concentrations of sodium and chloride on cellular processes and induced oxidative stress. Ion transport is the crucial starting point that determines salinity tolerance in plants. Transport via membranes is mediated mostly by the ion channels and transporters, which ensure selective passage of specific ions. The molecular and structural diversity of these ion channels and transporters is amazing. Obtaining the detailed descriptions of distinct ion channels and transporters present in halophytes, marine algae and salt-tolerant fungi and then progressing to the cellular and the whole organism mechanisms, is one of the logical ways to understand high salinity tolerance. Transfer of the genes from halophytes to agricultural crops is a means to increase salt tolerance of the crops. The theoretical scientific approaches involve protein chemistry, structure-function relations of membrane proteins, synthetic biology, systems biology and physiology of stress and ion homeostasis. At the time of compiling this e-book many aspects of ion transport under salinity stress are not yet well understood. The e-book has attracted researchers in ion transport and salinity tolerance. We have combined our efforts to achieve a wider, more detailed understanding of salt tolerance in plants mediated by ion transport, to understand present and future ways to modify and manipulate ion transport and salinity tolerance and also to find natural limits for the modifications.
Download or read book Algal Cell Motility written by Michael Melkonian and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algae exhibit the greatest variety of cell motility phenomena in the living world. These range from the peculiar gliding motility of filamentous blue green algae or cyanobacteria to chloroplast movements and cytoplasmic streaming which are most common in higher plants. In addition, cell motility by eukaryotic flagella is the characteristic mode of cell locomotion in algal flagellates and most reproductive cells of algae. Algae use these cell motility systems mainly to orient themselves or their photosynthetic organelles in a suitable light gradient to optimize growth and reproduction. In consequence most of the motility systems are coupled to photoreceptors and are regulated by signal transduction cascades. Algal cell motility has thus attracted consid erable interest also from non-phycologists and some algal motility systems have become models of research in cell and molecular biology. This book summarizes some of the progress that has been made in recent years in the analysis of cell motility phenomena in the algae. Although complete coverage of the subject was not attempted, the six chapters cover all the major types of cell motility systems and the authors provide in depth reviews of gliding motility, chloroplast movements, cytoplasmic streaming, flagellar beat pat terns, mechanisms of flagellar movement and centrin-mediated cell motility.
Download or read book Molecular Biology of Plant Tumors written by Günter Kahl and published by Academic Press. This book was released on 2014-06-28 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular Biology of Plant Tumors provides an opportunity to learn in detail about the latest insights into the mechanism of transformation of plant cells by Agrobacterium tumefaciens. The study of the molecular mechanism responsible for the crown gall phenomenon (induced by Agrobacterium tumefaciens) illustrates the point that the fundamental study of the cause(s) and mechanism(s) of abnormal growth might be one of the most efficient ways to understand cellular differentiation and the molecular basis of gene expression. The book is organized into three parts that contain research on abnormal plant growth, crown gall tumors, and potential vectors for genetic engineering in agriculture. The genetic structure responsible for the neoplasmic transformation of plant cells in crown galls is a bacterial plasmid (called Ti for tumor-inducing). Research described in this volume demonstrates that these Ti plasmids were designed by evolution as natural gene vectors with which some bacteria can introduce active genes into plants. These transferred genes are maintained by integration in the plant genome and their expression is directly or indirectly responsible for the tumorous growth pattern.
