Roots Of A Region

The third edition of a standard resource, this book offers a state-of-the-art, multi-disciplinary presentation of plant roots. It examines structure and development, assemblage of root systems, metabolism and growth, stressful environments, and interactions at the rhizosphere. Reflecting the explosion of advances and emerging technologies in the field, the book presents developments in the study of root origin, composition, formation, and behavior for the production of novel pharmaceutical and medicinal compounds, agrochemicals, dyes, flavors, and pesticides. It details breakthroughs in genetics, molecular biology, growth substance physiology, biotechnology, and biomechanics.

This book contains the majority of the presentations of the Second International Symposium on the Biology of Root Formation and Development that was hcld in Jerusa lem, Israel, June 23---28, 1996. Following the First Symposium on the Biology of Adventi tious Root Formation, held in Dallas. USA, 1993, we perceived the need to include all kinds of roots, not only the shoot-borne ones. The endogenous signals that control root formation. and the subsequent growth and development processes, are very much alike, re gardless of the sites and sources of origin of the roots. Therefore, we included in the Sec ond Symposium contributions on both shoot-borne (i.e., adventitious) roots and root-borne (i.e., lateral) roots. Plant roots have remained an exciting and an intriguing field of sciencc. During thc years that followed the first symposium, an exceptional proliferation of interest in root biology has developed, associated with the intensive research activity in this field and the contemporary developments in the understanding of root function and development. New methods have been applied, and old ideas and interprctations werc rccxamined. Alto gether, it became necessary to update our viewpoints and to expand them.

In 1971, the late Dr. J. Kolek of the Institute of Botany, Bratislava, organized the first International Symposium devoted exclusively to plant roots. At that time, perhaps only a few of the participants, gathered together in Tatranska Lomnica, sensed that a new era of root meetings was beginning. Nevertheless, it is now clear that Dr. Kolek's action, undertaken with his characteristic enormous enthusiasm, was rather pioneering, for it started a series a similar meetings. Moreover, what was rather exceptional at the time was the fact that the meeting was devoted to the functioning of just a single organ, the root. One possible reason for the unexpected success of the original, perhaps naive, idea of a Root Symposium might lie with the fact that plant roots have always been extremely popular as experimental material for cytologists, biochemists and physiologists whishing to probe processes as diverse as cell division and solute transport. Of course, the connection of roots with the rest of the plant is not forgotten either. This wide variety of disciplines is now coupled with the development of increasingly sophisticated experimental techniques to study some of these old problems. These factors undoubtedly contribute to the necessity of continuing the tradition of the root symposia. The common theme of root function gives, in addition, a certain unity to all these diverse activities.

The decade since the publication of the third edition of this volume has been an era of great progress in biology in general and the plant sciences in particular. This is especially true with the advancements brought on by the sequencing of whole genomes of model organisms and the development of "omics" techniques. This fourth edition of Plant Root

This book seeks to find creative and transformative relationship among roots and routes and create a new dynamics of awakening so that we can overcome the problems of closed and xenopbhobic roots and rootless cosmopolitanism. The book draws upon multiple philosophical and spiritual traditions of the world such as Siva Tantra, Buddhist phenomenology and Peircean Semiotics and discusses the works of Ibn-Arabi, Thoreau, Tolstoy, Gandhi and Raimon Panikkar,among others.The book is transdiscipinary building on creative thinking from philosophy, anthropology, political studies and literature. It is a unique contribution for forging a new relationship between roots and routes in our contemporary fragile and complex world.

Following its predecessors, Plant Roots: The Hidden Half, Fifth Edition is thoroughly updated and reports the major changes that have taken place in root research since the last edition published over 10 years ago. Considered a widely acclaimed book in the field of plant sciences, this edition includes a broad array of topics reflecting progress being made in the subdomains of root biology, featuring chapters on modern topics, while retained chapters are fully updated to demonstrate significant developments made in our understanding of root biology and in fast-evolving research methodologies and techniques. It reviews all root-related processes, from the evolution of roots in past eras to single-cell genomics, allowing readers to grasp an overall view of the state-of-the-art research in this field. Among the 104 contributors to this book are seasoned experts in the field, as well as uprising specialists who have already made a distinguished mark in scientific literature. All of the chapters are extensively referenced featuring specific information on any topic related to the biology of the hidden half of plants. Featuring full color illustrations throughout, this handbook is an essential source of information for both expert and novice root scientists.

Mangrove rice farming on West Africa's Rice Coast was the mirror image of tidewater rice plantations worked by enslaved Africans in 18th-century South Carolina and Georgia. This book reconstructs the development of rice-growing technology among the Baga and Nalu of coastal Guinea, beginning more than a millennium before the transatlantic slave trade. It reveals a picture of dynamic pre-colonial coastal societies, quite unlike the static, homogenous pre-modern Africa of previous scholarship. From its examination of inheritance, innovation, and borrowing, Deep Roots fashions a theory of cultural change that encompasses the diversity of communities, cultures, and forms of expression in Africa and the African diaspora.

The main purpose of this book is to provide the reader with a better understanding of spinal nerve root injuries caused by various pathologies (e.g. disc herniation, space-occupying lesions, trauma etc.). The standard anatomical description of spinal nerve roots origin, course and arrangement (described in the first chapters of the book) is now strongly influenced by the frequent findings of their intraspinal extradural and intradural connecting branches and by other variations, which are considered to be the major cause of the surgical therapy failures. Intraspinal extradural and intradural neuroanatomical roots variations may affect in fact the clinical picture, diagnosis, and surgical treatment; their recognition can minimize the damage to neural structures in the spinal anaesthesia, in spinal operations, in spondylosurgery, in endoscopic surgery, laser discectomy, etc. Their aetiology is unknown and it has to be elucidated, and they are rarely found during the usual preoperational examinations, a reason that encouraged various anatomical dissection studies finalized to their description. The data shown in this book will be surely helpful for traumatologists, orthopaedists, spinal surgeons, neurosurgeons, plastic surgeons and for all those dealing with intraspinal variations of nerve roots.
