Book excerpt: Shedding of Plant Parts focuses on the anatomical, physiological, and ecological features of shedding of vegetative and reproductive parts of plants. This book encompasses both natural and induced shedding. Organized into 12 chapters, this book first outlines the extent of shedding of plant cells, tissues, and organs and summarizes the biological and economic implications of such shedding. Separate chapters follow that discuss anatomical and histochemical changes in leaf abscission; the physiological ecology and internal regulation of abscission; and the shedding of shoots, branches, bark, roots, pollen, seeds, and reproductive structures of forest trees. This book also explains the anatomical changes in abscission of reproductive structures, chemical thinning of flowers and fruits, and chemical control of fruit abscission. This book will be valuable to plant anatomists, pathologists, and physiologists, and to agronomists, arborists, biochemists, ecologists, entomologists, foresters, horticulturists, landscape architects, meteorologists, and soil scientists.

Available in PDF, EPUB and Kindle. Book excerpt: Plant organ abscission is a developmental process regulated by the environment, stress, pathogens and the physiological status of the plant. In particular, seed and fruit abscission play an important role in seed dispersion and plant reproductive success and are common domestication traits with important agronomic consequences for many crop species. Indeed, in natural populations, shedding of the seed or fruit at the correct time is essential for reproductive success, while for crop species the premature or lack of abscission may be either beneficial or detrimental to crop productivity. The use of model plants, in particular Arabidopsis and tomato, have led to major advances in our understanding of the molecular and cellular mechanisms underlying organ abscission, and now many workers pursue the translation of these advances to crop species. Organ abscission involves specialized cell layers called the abscission zone (AZ), where abscission signals are perceived and cell separation takes place for the organ to be shed. A general model for plant organ abscission includes (1) the differentiation of the AZ, (2) the acquisition of AZ cells to become competent to respond to various abscission signals, (3) response to signals and the activation of the molecular and cellular processes that lead to cell separation in the AZ and (4) the post-abscission events related to protection of exposed cells after the organ has been shed. While this simple four-phase framework is helpful to describe the abscission process, the exact mechanisms of each stage, the differences between organ types and amongst diverse species, and in response to different abscission inducing signals are far from elucidated. For an organ to be shed, AZ cells must transduce a multitude of both endogenous and exogenous signals that lead to transcriptional and cellular and ultimately cell wall modifications necessary for adjacent cells to separate. How these key processes have been adapted during evolution to allow for organ abscission to take place in different locations and under different conditions is unknown. The aim of the current proposal is to present and be able to compare recent results on our understanding of organ abscission from model and crop species, and to provide a basis to understand both the evolution of abscission in plants and the translation of advances with model plants for applications in crop species.

Available in PDF, EPUB and Kindle. Book excerpt: Woody plants such as trees have a significant economic and climatic influence on global economies and ecologies. This completely revised classic book is an up-to-date synthesis of the intensive research devoted to woody plants published in the second edition, with additional important aspects from the authors' previous book, Growth Control in Woody Plants. Intended primarily as a reference for researchers, the interdisciplinary nature of the book makes it useful to a broad range of scientists and researchers from agroforesters, agronomists, and arborists to plant pathologists and soil scientists. This third edition provides crutial updates to many chapters, including: responses of plants to elevated CO2; the process and regulation of cambial growth; photoinhibition and photoprotection of photosynthesis; nitrogen metabolism and internal recycling, and more. Revised chapters focus on emerging discoveries of the patterns and processes of woody plant physiology. * The only book to provide recommendations for the use of specific management practices and experimental procedures and equipment*Updated coverage of nearly all topics of interest to woody plant physiologists* Extensive revisions of chapters relating to key processes in growth, photosynthesis, and water relations* More than 500 new references * Examples of molecular-level evidence incorporated in discussion of the role of expansion proteins in plant growth; mechanism of ATP production by coupling factor in photosynthesis; the role of cellulose synthase in cell wall construction; structure-function relationships for aquaporin proteins

The process has often been described asv ke of self-pruning by which the plant rids itself of useless portions of its body. Since abscission is somctimes confused with exfoliation, it seems desirable here to distinguish definitely between thme two phenomena. It can BC said that, in general, exfoliation is preccded by drying and death of the part to be cast off and that actual separa- tion of the organ is accomplished by a mechanical break through dry, dead tissues. Abscission, on the other hand, is usually not preceded by drying and death of the organ concerned and its detachment is accomplished by a separation along thc plane of the middle lamellae of active living cells. Abscission may he either axial or lateral. Axial abscission includes the abscission of portions of stems, shook, entire flowem or fruits. Lateral abscission includes the abskssion of lcavcs, petioks, sepals, pctah or styles..

This book was released on 2008-04-15 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cell separation is an important process that occurs throughout the life cycle of a plant. It enables the radicle to emerge from the germinating seed, vascular tissue to differentiate, sculpturing of leaves and flowers to take place, pollen to be shed from the mature anther, fruit to soften, senescent and non-functional organs to be lost, and seeds to be shed. In addition to its intrinsic scientific interest, many of the developmental processes to which it contributes have importance for agriculture and horticulture. This is the first volume to focus exclusively on these processes and to link improvements in our scientific understanding with methods that may allow us to manipulate cell separation and adhesion to the benefit of the agricultural and horticultural industries. It will therefore be of interest to the experimental scientist and to those who wish to apply these techniques commercially.

Available in PDF, EPUB and Kindle. Book excerpt: As the oldest and largest human intervention in nature, the science of agriculture is one of the most intensely studied practices. From manipulation of plant gene structure to the use of plants for bioenergy, biotechnology interventions in plant and agricultural science have been rapidly developing over the past ten years with immense forward leaps on an annual basis. This book begins by laying the foundations for plant biotechnology by outlining the biological aspects including gene structure and expression, and the basic procedures in plant biotechnology of genomics, metabolomics, transcriptomics and proteomics. It then focuses on a discussion of the impacts of biotechnology on plant breeding technologies and germplasm sustainability. The role of biotechnology in the improvement of agricultural traits, production of industrial products and pharmaceuticals as well as biomaterials and biomass provide a historical perspective and a look to the future. Sections addressing intellectual property rights and sociological and food safety issues round out the holistic discussion of this important topic. Includes specific emphasis on the inter-relationships between basic plant biotechnologies and applied agricultural applications, and the way they contribute to each other Provides an updated review of the major plant biotechnology procedures and techniques, their impact on novel agricultural development and crop plant improvement Takes a broad view of the topic with discussions of practices in many countries
