Book excerpt: This book delves into the many facets of the study of plant development and demonstrates the importance of ontogenetic studies in analyzing the structure, function, and evolution of glands, structures, and organs. The nine chapters that make up this book represent the state of the art of the scientific knowledge on the subject and bring unpublished contributions and important reviews of the most diverse developmental issues of plants compiled for the first time in a single book. Chapter 1 describes an unprecedented way secretory ducts form as the result of cavity coalescence in Malvaceae. Chapter 2 describes a case of homeoheterotopic alteration between nectaries and colleters in Passifloraceae and analyzes the evolution of leaf glands in the family. Chapter 3 emphasizes the importance of anatomical, histochemical and ontogenetic studies in distinguishing colleters and nectaries in leaves of Sapium (Euphorbiaceae) and highlights the importance of ontogenetic studies for the observation of new colleters since many of them are deciduous. Chapter 4 reviews leaf development in vascular plants using traditional morphological and anatomical knowledge combined with the most recent data obtained in molecular studies. Chapter 5 reviews the morphogenesis and evolution of haustoria in mistletoes and evaluates the likely reasons that led to the change from root parasitism to aerial parasitism in Santalales. Chapter 6 demonstrates the importance of the meristematic activity and bud formation for the structure of inflorescences in Acanthaceae, revealing the causes of their architectural diversity in genera such as Lepidagathis. Chapter 7 reveals the ontogenetic causes that resulted in varying degrees of flower reduction, separation of sexes, and their relationship with pollination in urticalean rosids. Chapter 8 uses the ontogenetic study of flowers to analyze the diversity of polyads in Leguminosae and their importance in the taxonomy of the family and the dispersal mode of pollen. Chapter 9 investigates the mode of formation of the pseudomonomerous gynoecia using Anacardiaceae as a model and discusses the evolution of this morphological reduction of gynoecium in other lineages of angiosperms.
Download or read book Ontogeny Cell Differentiation and Structure of Vascular Plants written by Roger Buvat and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: With improved microscope and preparation techniques, studies of histo logical structures of plant organisms experienced a revival of interest at the end of the 19th century. From that time, histological data have sub stantially studies of the pioneers in botanical science. From the beginning of the 20th century, the microscope allowed research in cell structure, the general functional unit of living beings. Advances in cytology gradually influenced histology, at first, however, rather timidly. Only the new and spectacular progress in ultrastructural cytology and cytochemistry led to a great increase in modern work on the structures of vascular plants and the related ontogenical and physiological data, thanks to the use of the electron microscope and the contribution of molecular biology. Not only did new techniques lead to new approaches, but achieve ments in general biology shifted the orientation of research, linking in vestigation to the physiological aspects of cell and tissue differentiation. Among these, the demonstration of the general principles of develop ment, and the characterization of molecules common to plants and animals, which control and govern the main basic functions of cells and tissues, have widened the scope of modern research on plant struc tures. Present trends in biological research show that it is necessary to know the structures thoroughly, from the ultrastructural cytological scale to the scale of tissue and organ arrangement, even for physiological research on either cells, tissues, or whole organs. The study of growth factors, differ entiation, or organogenesis can be mentioned as an example.

Available in PDF, EPUB and Kindle. Book excerpt: This collection of short stories focuses on the Scottish civil war of 1644-45, in which the Marquis of Montrose led his royalist forces in a series of stunning victories against the odds before his final defeat at Philiphaugh. Each of Hogg's five tales centres on one of the five major battles of Montrose's brilliant but ultimately futile campaign. Each tale is utterly different from the others in genre and tone, but taken together they build up a composite picture of what it was like to experience the 'anarchy and confusion' of the time at first hand.
Download or read book Mechanisms in Plant Development written by Ottoline Leyser and published by John Wiley & Sons. This book was released on 2009-04-01 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intended for undergraduate and graduate courses in plant development, this book explains how the cells of a plant acquire and maintain their specific fates. Plant development is a continuous process occurring throughout the life cycle, with similar regulatory mechanisms acting at different stages and in different parts of the plant. Rather than focussing on the life cycle, the book is structured around these underlying mechanisms, using case studies to provide students with a framework to understand the many factors, both environmental and endogenous, that combine to regulate development and generate the enormous diversity of plant forms. New approach to the study of plant development and a refreshing look at this fast-moving area. Authors focus their discussion on the basic mechanisms which underpin plant development, tackling the fundamental question of how a single cell becomes a complex flowering plant from a cellular perspective. An up-to-date, modern text in plant development for advanced level undergraduates and postgraduates in plant science. Thought-provoking treatment of a difficult subject, the text will satisfy the needs of advanced level undergraduates and postgraduates in plant science. Experimental case studies throughout.

Download or read book Size and Age Related Changes in Tree Structure and Function written by Frederick C. Meinzer and published by Springer Science & Business Media. This book was released on 2011-06-29 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of trees live and grow all around us, and we all recognize the vital role they play in the world’s ecosystems. Publicity campaigns exhort us to plant yet more. Yet until recently comparatively little was known about the root causes of the physical changes that attend their growth. Since trees typically increase in size by three to four orders of magnitude in their journey to maturity, this gap in our knowledge has been a crucial issue to address. Here at last is a synthesis of the current state of our knowledge about both the causes and consequences of ontogenetic changes in key features of tree structure and function. During their ontogeny, trees undergo numerous changes in their physiological function, the structure and mechanical properties of their wood, and overall architecture and allometry. This book examines the central interplay between these changes and tree size and age. It also explores the impact these changes can have, at the level of the individual tree, on the emerging characteristics of forest ecosystems at various stages of their development. The analysis offers an explanation for the importance of discriminating between the varied physical properties arising from the nexus of size and age, as well as highlighting the implications these ontogenetic changes have for commercial forestry and climate change. This important and timely summation of our knowledge base in this area, written by highly respected researchers, will be of huge interest, not only to researchers, but also to forest managers and silviculturists.

Download or read book Epigenetic Principles of Evolution written by Nelson R Cabej and published by Elsevier. This book was released on 2011-11-22 with total page 847 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first and only book, so far, to deal with the causal basis of evolution from an epigenetic view. By revealing the epigenetic "user" of the "genetic toolkit", this book demonstrates the primacy of epigenetic mechanisms and epigenetic information in generating evolutionary novelties. The author convincingly supports his theory with a host of examples from the most varied fields of biology, by emphasizing changes in developmental pathways as the basic source of evolutionary change in metazoans. - Original and thought provoking--a radically new theory that overcomes the present difficulties of the theory of evolution - Is the first and only theory that uses epigenetic mechanisms and principles for explaining evolution of metazoans - Takes an integrative approach and shows a wide range of learning
Download or read book Induced Responses to Herbivory written by Richard Karban and published by University of Chicago Press. This book was released on 2007-12-01 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants face a daunting array of creatures that eat them, bore into them, and otherwise use virtually every plant part for food, shelter, or both. But although plants cannot flee from their attackers, they are far from defenseless. In addition to adaptations like thorns, which may be produced in response to attack, plants actively alter their chemistry and physiology in response to damage. For instance, young potato plant leaves being eaten by potato beetles respond by producing chemicals that inhibit beetle digestive enzymes. Over the past fifteen years, research on these induced responses to herbivory has flourished, and here Richard Karban and Ian T. Baldwin present the first comprehensive evaluation and synthesis of this rapidly developing field. They provide state-of-the-discipline reviews and highlight areas where new research will be most productive. Their comprehensive overview will be welcomed by a wide variety of theoretical and applied researchers in ecology, evolutionary biology, plant biology, entomology, and agriculture.

Available in PDF, EPUB and Kindle. Book excerpt: Plant Growth and Development: A Molecular Approach presents the field of plant development from both molecular and genetic perspectives. This field has evolved at a rapid rate over the past five years through the increasing exploitation of the remarkable plant Arabidopsis. The small genome, rapid life cycle, and ease of transformation of Arabidopsis, as well as the relatively large number of laboratories that are using this plant for their research, have lead to an exponential increase in information about plant development mechanisms.In Plant Growth and Development: A Molecular Approach Professor Fosket synthesizes this flood of new information in a way that conveys to students the excitement of this still growing field. His textbook is based on notes developed over more than ten years of teaching a course on the molecular analysis of plant growth and development and assumes no special knowledge of plant biology. It is intended for advanced undergraduates in plant development, as well as those in plant molecular biology. Graduate students and researchers who are just beginning to work in the field will also find much valuable information in this book. Each chapter concludes with questions for study and review as well as suggestions for further reading.

Download or read book Microspores written by Stephen Blackmore and published by Academic Press. This book was released on 1990 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: An understanding of the processes of plant reproduction is increasingly important in the exploitation of plant resources. Microspore formation is a major event in the life cycles of land plants, allowing the transition from diploid sporophyte generation to the haploid gametophyte generation, and varies greatly between taxa in the diversity of processes involved. Despite the wealth of information available, there are very few sources which bring together the results of research work on the reproduction in all the major plant groups.**Microspores fills this gap by reviewing microsporogenesis from a systematic and evolutionary perspective in groups ranging from algae to angiosperms. Special chapters focus on structure, function, cell and molecular processes, and potential biotechnological applications of plant spores and pollen. The result is an up-to-date guide to the applications of modern techniques in the classic area of botany.**This work bridges several disciplines to provide a coherent and authoritative account which will be essential reading for research scientists and lecturers in botany, evolution, ultrastructure, reproductive and developmental biology, and palynology.

Download or read book Plant Hormones written by P.J. Davies and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 843 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant hormones play a crucial role in controlling the way in which plants growand develop. Whilemetabolism providesthepowerand buildingblocks for plant life, it is the hormones that regulate the speed of growth of the individual parts and integrate these parts to produce the form that we recognize as a plant. In addition, theyplayacontrolling role inthe processes of reproduction. This book is a description ofthese natural chemicals: how they are synthesizedand metabolized; howthey work; whatwe knowoftheir molecular biology; how we measure them; and a description ofsome ofthe roles they play in regulating plant growth and development. Emphasis has also been placed on the new findings on plant hormones deriving from the expanding use ofmolecular biology as a tool to understand these fascinating regulatory molecules. Even at the present time, when the role of genes in regulating all aspects of growth and development is considered of prime importance, it is still clear that the path of development is nonetheless very much under hormonal control, either via changes in hormone levels in response to changes in gene transcription, or with the hormones themselves as regulators ofgene transcription. This is not a conference proceedings, but a selected collection ofnewly written, integrated, illustrated reviews describing our knowledge of plant hormones, and the experimental work that is the foundation of this knowledge.

Download or read book Essentials of Developmental Plant Anatomy written by Taylor A. Steeves and published by Oxford University Press. This book was released on 2017 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main aim of this book is to provide a developmental perspective to plant anatomy. Authors Steeves and Sawhney provide fundamental information on plant structure and development to students at the introductory level, and as a resource material to researchers working in nearly all areas of plant biology i.e., plant physiology, systematics, ecology, developmental genetics and molecular biology. The book is focused on angiosperm species with some examples from different groups of plants. "Essentials of Developmental Plant Anatomy" starts with an introductory chapter and a brief introduction to plant cell structure, which is followed by the structure of the flower, plant reproduction (vegetative and sexual) and the development and structure of embryo - the precursor to the plant body. Each chapter then deals with essential information on the shoot system, diversity of plant cells and tissues, the structure and development of the stem, leaf, root, and the secondary body.
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.
