Jointly published with INRA, Paris. Bacterial wilt, caused by Ralstonia solanacearum, is a very destructive plant disease that attacks over 450 different species, including many of the most important economic crop plants. Often endemic, the bacterium transmits through the soil, penetrates the plant root system and eventually causes irreversible wilting and death. This book summarizes the current information on bacterial wilt for both the basic research community and for concerned professionals who are faced with the disease in the field, offering the latest approaches to diagnosis and control of the disease. Emphasis is placed on integrated and biologically sustainable control methods. Also presented is the most recent genetic/biochemical research exploring the interaction between the bacterium and its plant host at the molecular level.
Pasteurization, penicillin, Koch's postulates, and gene coding. These discoveries and inventions are vital yet commonplace in modern life, but were radical when first introduced to the public and academia. In this book, the life and times of leading pioneers in microbiology are discussed in vivid detail, focusing on the background of each discovery and the process in which they were developed — sometimes by accident or sheer providence.
This anthology traces the fascinating progress from plant pathology to biotechnology through 38 scientific papers on Agrobacterium, published over the past century. Included are the seminal scientific papers on the biology and application of Agrobacterium with introductory commentaries mostly by those involved in the original work. The commentaries give background to the papers and explain the problems faced and the techniques used, providing insight into the way fundamental research progresses.Agrobacterium tumefaciens has played a major role in the astounding advances that have been made over the past several decades in the areas of plant genetics, plant molecular biology, and plant genetic engineering. The papers included in this book were integral to the current understanding of the interaction of Agrobacterium with its hosts, its development into a major player in the genetic engineering of plants, and the biological control of crown gall.Agrobacterium tumefaciens: From Plant Pathology to Biotechnology is divided into five sections. The first section begins with 1904 when Erwin F. Smith began detailed work on crown gall and considered it to be a plant pathological problem. It explores many of the biological discoveries made over the past century, including the pivotal moment when Armin C. Braun discovered that crown gall was a plant cancer. Other papers cover the beginnings of T-DNA research and the development of vectors to improve the process of transferring T-DNA from bacterium to plant cell. The second section delves further into vector systems and genetic coding for disease and insect resistance, exploring the evolution of genetic engineering in crops.The final three sections deal with themes developed from crown gall studies, including ?quorum sensing? or population density, the DNA sequencing of one strain of A. tumefaciens, and the first genetically engineered organism, strain K1026, released for commercial use.According to Editor, Eugene Nester, ?This book should serve as a testimony to the 100 years of research on this remarkable organism, as well as to an international group of investigators who helped reveal secrets of this natural genetic engineer.? Students, professors, plant pathologists, microbiologists, or anyone interested in research and/or the history of plant pathology and biotechnology, will find this collection of papers an intriguing read.From the Preface: ??the journey is not over. As the commentary by Paul Hooykaas indicates, it looks as though T-DNA will insert into any cell, be it plant, fungal or even mammalian. Is there a possibility of using Agro?bacterium in gene therapy? Will Agrobacterium prove to be as useful a tool in fungal genetics as it has been in plant genetics? Its potential is mind-boggling.?
This volume reviews all aspects of Mars atmospheric science from the surface to space, and from now and into the past.
Based on a 15-year successful approach to teaching aircraft flight mechanics at the US Air Force Academy, this text explains the concepts and derivations of equations for aircraft flight mechanics. It covers aircraft performance, static stability, aircraft dynamics stability and feedback control.
Fungal Wilt Diseases of Plants focuses on wilt diseases caused by the fungal genera Verticillium, Fusarium, and Ceratocystis. Special attention is given to the interactions of physiological, biochemical, and anatomical factors, as these relate to pathogenesis and mechanisms of disease resistance. Organized into 16 chapters, this book begins with a description, in a historical perspective, of the major research themes in fungal wilt diseases. It then looks into the worldwide status of this plant disease. The three subsequent chapters describe the epidemiology and life cycle of the major fungal wilt pathogens in Fusarium, Verticillium, and Ceratocystis. This book also provides an in-depth view of the genetics and biochemistry of these pathogens; the nature of pathogenesis and the effects of wilt pathogens on host-water relations; and the sources and genetics of host resistance in field and fruit crops, vegetable crops, and shade trees. Other chapters are dedicated to the biochemistry, physiology, and the anatomical aspects of resistance and to the progress in the biological and chemical control of these pathogens. This text will be of great value to graduate students and senior research scientists in plant pathology, physiology, and biochemistry, who are specifically involved in studying wilt diseases and host-parasite interactions. It will provide them the detailed background information needed to supplement their specialized research interests.
Every year we see a remarkable increase in scientific knowledge. We are learning more each day about the world around us, about the numerous biological organisms of the biosphere, about the physical and chemical processes that shaped and continue to change our planet. The cataloging, retrieval, dissemination, and use of this new information along with the continued development of new computer technology provide some of the most challenging problems in science as we enter the Information Age. With the explosion of knowledge in science, it is especially important that students in introductory courses learn not only the basic material of a subject, but also about the newest developments in that subject. With this goal in mind, we have prepared a second edition of Introduction to Plant Diseases: Identification and Management. We prepared this edition with the same general purpose that we had for the first edition - to provide practical, up-to-date information that helps in the successful management of diseases on food, fiber, and landscape plants for students who do not have a strong background in the biological sciences. We included new information on (1) the precise identification of diseases and the pathogens that cause them, (2) the development of epidemics of plant diseases, (3) the application of biotechnology in plant pathology, (4) the use of alternative methods of crop production and disease management that help protect the environment, and (5) diseases that have become more important since the first edition was published.
