This book was released on 1985-04-30 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the extreme diversity of aquatic and terrestrial plant genera, each has characteristic cell wall forms. A number of hypotheses have been advanced to explain differences in microfibril arrangements across anyone such wall. Of those, only the 'multinet' theory, which involves the postulation of reorientation of microfibrils caused by cell extension, now has a substantial number of ad herents. However, many scientists are sceptical of its validity; obviously it is incompatible with various observed microfibril arrangements. The tenet of this study is that any such hypothesis can be valid only if it is applicable to all plant forms and wall types. Initially, reanalyses are made of data claimed to confirm justification for multi net postulations. The results show that previous deductions from those data, in support of multinet, are subject to serious challenge. Similarly, a re-examination of the observations, which inspired the multinet theory, shows they have a more logical explanation. Herein, it is concluded that cell wall development involves biophysical factors, which neces sarily prevent multinet's postulated large reorientations of microfibrils, after their formation. Unfortunately the previously most recent published theory, which is based on the absence of reorientation during extension, fails to answer the fundamental question of how alternating orientations between lamellae are controlled, or explain variations in thickness of wall layers. Extensive published data are used to identify forces involved in cell wall development.

Download or read book Differential Growth in Plants written by Peter W. Barlow and published by Elsevier. This book was released on 2013-10-22 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Differential Growth in Plants contains the papers presented at Symposia 2.04 ""Spatial and Temporal Patterns of Development"" and 2.14 ""Movements Based on Differential Flank Growth"" at the XIV Botanical Congress held in Berlin during July 1987. Organized into 10 chapters, this book begins by explaining the differential growth in plants. Some chapters follow on the biophysics of differential growth; the phototropic behavior of hypocotyls and coleoptiles in connection with the distribution of indole-3-acetic acid and of growth-inhibiting substances within them; and the differential growth and hormone redistribution in gravireacting maize roots. Other topics explained include plant movements caused by differential growth; genetic analysis of tropic responses; growth and bending of a cylindrical structure in terms of the distribution of relative growth rates; and differential growth resulting in the specification of different types of cellular architecture in root meristems. This book also elucidates the curving and twinning of stems, as well as the spatio-temporal analysis of flower ontogenesis.

Book excerpt: This volume emphasizes the involvement of all facets of biology in the analysis of environmentally controlled movement responses. This includes biophysics, biochemistry, molecular biology and as an integral part of any approach to a closer understanding, physiology. The initial euphoria about molecular biology as the final solution for any problem has dwindled and the field agrees now that only the combined efforts of all facets of biology will at some day answer the question posed more than hundred years ago: "How can plants see?". One conclusion can be drawn from the current knowledge as summarized in this volume. The answer will most likely not be the same for all systems.

Available in PDF, EPUB and Kindle. Book excerpt: The Cytoskeleton of the Algae provides a comprehensive examination of the structural features of the cytoskeleton in phylogenetic branches of algae. The book also analyzes the possible functions of cytoskeletal components using structural, physiological, genetic, and molecular approaches. Many taxa are described in detail, mirroring the dramatic progress that has been made in recent years in this new research field. Many unique structural elements and motility phenomena are described for the first time, and other features common to all plant cells, such as cell polarity, cytoplasmic streaming, mitosis, cell wall deposition, and contractile events are analyzed using algae as experimental model systems. The Cytoskeleton of the Algae reflects the enormous impact that research on the algal cytoskeleton has on both phycology and plant cell biology, and it will serve as an excellent reference volume for researchers in this area.

Available in PDF, EPUB and Kindle. Book excerpt: Manipulation of plant architecture is regarded as a new and promising issue in plant biotechnology. Given the important role of the cytoskeleton during plant growth and development, microtubules provide an important target for biotechnological applications aiming to change plant architecture. This book introduces some microtubule-mediated key processes that are important for plant life and amenable to manipulation by either genetic, pharmacological or morphological rationales. In the first part, the role of microtubules in plant morphogenesis is reviewed. The second part covers their role in response to environmental factors. The third part deals with the tools that can be used for biotechnological manipulation.

Available in PDF, EPUB and Kindle. Book excerpt: Biochemistry is the branch of science use to study chemical reactions in organisms. Biotechnology is a branch of science which help as catalyst (device or instrument) study biochemistry and many other field of science. Examining cells at a molecular level, biochemistry develops our understanding of the chemistry of life, revealing the complex processes in operation in living systems. Biotechnology harnesses these advances of understanding for beneficial use in industry, medicine and agriculture. Amino acids can be joined covalently through peptide bonds to form peptides, which can also be formed by incomplete hydrolysis of polypeptides. The acid-base behavior and chemical reactions of a peptide are functions of its amino-terminal amino group, its carboxyl-terminal carboxyl group, and its R groups. Peptides can be hydrolyzed to yield free amino acids. Some peptides occur free in cells and tissues and have specific biological functions. These include some hormones and antibiotics, as well as other peptides with powerful biological activity. At its simplest, biotechnology is technology based on biology - biotechnology harnesses cellular and biomolecular processes to develop technologies and products that help improve our lives and the health of our planet. We have used the biological processes of microorganisms for more than 6,000 years to make useful food products, such as bread and cheese, and to preserve dairy products. This book present a succinct account of the essential features of the biochemistry and biotechnology, and is being prepared by keeping in view the requirements of the students and academic professionals.

Download or read book Plant Development written by Robert Lyndon and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of plant development in recent years has often been concerned with the effects of the environment and the possible involvement of growth substances. The prevalent belief that plant growth substances are crucial to plant development has tended to obscure rather than to clarify the underlying cellular mechanisms of development. The aim in this book is to try to focus on what is currently known, and what needs to be known, in order to explain plant development in terms that allow further experimentation at the cellular and molecular levels. We need to know where and at what level in the cell or organ the critical processes controlling development occur. Then, we will be better able to under stand how development is controlled by the genes, whether directly by the continual production of new gene transeripts or more indirectly by the genes merely defining self-regulating systems that then function autonomously. This book is not a survey of the whole of plant development but is meant to concentrate on the possible component cellular and molecular processes involved. Consequently, a basic knowledge of plant structure is assumed. The facts of plant morphogenesis can be obtained from the books listed in the General Reading seetion at the end of Chapter 1. Although references are not cited specifically in the text, the key references for each section are denoted by superscript numbers and listed in the Notes section at the end of each chapter.

Download or read book Biology of Fibrous Composites written by Anthony Charles Neville and published by Cambridge University Press. This book was released on 1993 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, by a leading thinker with 30 years experience in the field, is the first devoted to fibrous composites in biology. It tackles a major unsolved problem in developmental biology - how does chemistry create architecture outside cells? Fibrous composites occur in all skeletal systems including plant cell walls, insect cuticles, moth eggshells, bone and cornea. They function like man-made fibreglass, with fibres set in a matrix. The fibrous molecules are long, extracellular and water-insoluble and to be effective they must be orientated strategically. The underlying hypothesis of this book is that the fibres are orientated by self-assembly just outside the cells during a mobile liquid crystalline phase prior to stabilization. The commonest orientations of the fibres are plywood laminates (orthogonal and helicoidal), and as parallel fibres. These may be imitated in vitro by liquid crystalline chemicals. The book takes an interdisciplinary approach and will be relevant to biologists, biochemists, biophysicists, material scientists and to liquid crystals chemists.
