Download or read book Gravity and the Behavior of Unicellular Organisms written by Donat-Peter Häder and published by Cambridge University Press. This book was released on 2005-01-17 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unicellular organisms use gravity as an environmental guide to reach and stay in regions optimal for their growth and reproduction. These single cells play a significant role in food webs and these factors together make the effects of gravity on unicellular organisms a fascinating and important subject for scientific study. In addition, they present valuable model systems for studying the mechanisms of gravity perception, a topic of increasing interest in these days of experimentation in space. This book reveals how single cells achieve the same sensoric capacity as multicellular organisms like plants or animals. It reviews the field, discussing the historical background, ecological significance and related physiology of unicellular organisms, as well as various experimental techniques and models with which to study them. Those working on the biology of unicellular organisms, as well as in related areas of gravitational and space science will find this book of value.

Available in PDF, EPUB and Kindle. Book excerpt: Commentaries in Plant Science, Volume 2 is a collection of papers that reviews developments in the pure and applied science of plants. One paper discusses the role of supercooling in the winter survival mechanism of and ecological distribution of many plant communities. Another paper evaluates the Cholodny-Went theory of shoot geotropism that there is strong evidence in auxin redistribution occurring in a rapid manner to cause geotropic curvature. The magnitude of auxin redistribution is too rare to cause differential growth. Some insect pests have specific nutritional requirements and well-developed mechanisms for selecting their plant host. One paper enumerates the benefits of using insect-resistant host plant varieties, such as the non-incurrence of extra costs, these are environmentally safe, and are compatible with most other methods of pest control. Another paper discusses the nature and possible genetic manipulation of a complex bacteria, the actinomycetes, as well as its role as antibiotic producer. Another paper examines the nature of seed storage proteins and of the cellular processes that are related in their synthesis and deposition especially in cereals and legume. This collection is suitable for botanists, genecologists, taxonomists, biologists, and investigators whose works involve cell membrane research.

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: Volume 72 is wholly dedicated to the topic of plant hormones. Although Vitamins and Hormones is normally dedicated to mammalian hormone action, this volume is unique to plants and their actions through receptors. The genetic aspects and the receptorology are reminiscent of the mammlian systems. The well-known hormones are reviewed including cytokinins, abscicic acid, gibberellin and auxin. In addition there are reviews on nitric oxide, brassinosteroids, jasmonate, ethylene, and pheromones. Other topics included are genes that are regulated by abscicic acid and gibberellin, functional differentiation and transition of peroxisomes, plant antioxidants, gravitropic bending and the actions of plant hormones on glutathione transferase. *Includes color illustrations *Available on ScienceDirect *Longest running series published by Academic Press *Contributions by leading international authorities
Download or read book Gravitational Biology I written by Markus Braun and published by Springer. This book was released on 2018-07-20 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes what is currently known about gravity sensing and response mechanisms in microorganisms, fungi, lower and higher plants; starting from the historical eye-opening experiments from the 19th century up to today’s extremely rapid advancing cellular, molecular and biotechnological research. All forms of life are constantly exposed to gravity and it can be assumed that almost all organisms have developed sensors and respond in one way or the other to the unidirectional acceleration force,this books shows us some of these different ways. The book is written for plant biologists and microbiologists as well as scientists interested in space and gravitational biology.

Download or read book Polar Auxin Transport written by Rujin Chen and published by Springer Science & Business Media. This book was released on 2013-04-03 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of the plant growth regulator auxin for plant growth has long been recognized, even before the discovery of its chemical structures in the early 20th century. Physiological studies in the decades since have demonstrated that auxin is unidirectionally transported in plants, a process dubbed polar auxin transport. It is the polar auxin transport process that generates a local auxin concentration gradient and regulates a broad array of physiological and developmental processes. The discoveries of auxin transport carrier proteins that mediate auxin influx into and efflux out of transport-competent cells and auxin receptor proteins for auxin signaling in the last few decades represent significant milestones in auxin research and open up opportunities to probe the cellular and molecular processes that regulate auxin transport and integrate environmental cues with signaling processes. Remarkably, components of the polar auxin transport machinery are present in both lower plants such as mosses and higher plants including monocots and eudicots, illustrating the key role of polar auxin transport in plant evolution. This book highlights topics ranging from physiological and genetic studies of polar auxin transport in plant development, to growth responses to the environment and plant-microbe interactions, to hormonal cross-talks with various cellular and molecular regulatory processes essential for polar auxin transport.

Download or read book Plant Tropisms written by Simon Gilroy and published by John Wiley & Sons. This book was released on 2008-06-02 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropisms, the defined vectorial stimuli, such as gravity, light, touch, humidity gradients, ions, oxygen, and temperature, which provide guidance for plant organ growth, is a rapidly growing and changing field. The last few years have witnessed a true renaissance in the analysis of tropisms. As such the conception of tropisms has changed from being seen as a group of simple laboratory curiosities to their recognition as important tools/phenotypes with which to decipher basic cell biological processes that are essential to plant growth and development. Plant Tropisms will provide a comprehensive, yet integrated volume of the current state of knowledge on the molecular and cell biological processes that govern plant tropisms.
