Epidemiologia e controle. Estimativa de perdas causadas por bacteria, melhoramento para resistencia. Bioquimica e relacionamento de parasitas danosos.
This comprehensive manual of phytobacteriology is heavily illustrated with over 200 colour photographs and line illustrations. It begins by outlining the history and science of bacteriology and gives an overview of the diversity and versatility of complex bacteria. It then explains the characterization, identification and naming of complex bacteria, and explores how bacteria can cause disease and how plants react to such disease. The book also discusses the economic importance of bacterial diseases as well as strategies for their control and the reduction of crop losses. It concludes with fifty examples of plant pathogenic bacteria and the diseases that they cause.
This book is a comprehensive manual of phytobacteriology and is rich in illustrations with over 200 colour photographs and line illustrations. It starts by briefly outlining the history and science of bacteriology and gives an overview of the diversity and versatility of bacteria. It goes on to explain diagnosis of bacterial plant diseases, including detection, characterization and identification of plant-pathogenic bacteria using conventional and molecular methods, and furthermore, how bacteria can cause disease and plants' reaction to this. It also discusses the epidemiology and economic importance of bacterial diseases and strategies for their prevention and control in order to reduce crop losses. This book concludes with some 50 examples of well and lesser known plant-pathogenic bacteria and the diseases that they cause.
Fire Blight: The Foundation of Phytobacteriology tells the story of the exciting first decades of fire blight research. This fascinating collection of papers from the early 19th and 20th centuries highlights work from three notable scientists who pioneered work on the disease ? Thomas Jonathan Burrill, Joseph Charles Arthur, and Merton Benway Waite.These papers establish the fundamental concept that bacteria could cause plant disease and provide the first proof that insects acted as vectors of plant pathogens. The discoveries recorded here belong to the same class of scientific breakthroughs as the work on rust and smut disease in the 1850?s, which revealed the fact of fungal pathogenicity. The importance of the early studies on fire blight also relate to the development of biology and bacteriology because the revelation that bacteria could cause plant disease came at virtually the same time as the similar discovery with human and animal diseases. And the research in the role of insects in the spread of disease appeared contemporaneously with reports of insect vectors in animal disease.Plant pathologists, horticulturists, and historians of science will treasure this collection of papers that expose not only the early details on fire blight but also the identification of the need for research and the authors? experimental techniques. Carefully selected by the editors, the papers clearly reveal the developing nature of plant pathology and lead the reader through the captivating ? and sometimes lesser known ? research of times gone by.
This book is based mainly on invited and offered papers presented at the Second International Symposium on Bacterial and Bacteria-like Contaminants of Plant Tissue Cultures held at University College, Cork, Ireland in September 1996, with additional invited papers. The First International Symposium on Bacterial and Bacteria-like Contaminants of Plant Tissue Cultures was held at the same venue in 1987 and was published as Acta Horticulturae volume 225, 1988. In the intervening years there have been considerable advances in both plant disease diagnostics and in the development of structured approaches to the management of disease and microbial contamination in micropropagation. These approaches have centred on attempts to separate, spatially, the problems of disease transmission and laboratory contamination. Disease-control is best achieved by establishing pathogen-free cultures while laboratory contamination is based on subsequent good working practice. Control of losses due to pathogens and microbial contamination in vitro addresses, arguably, the most importance causes of losses in the industry; nevertheless, losses at and post establishment can also be considerable due to poor quality microplants or micro-shoots. In this symposium, a holistic approach to pathogen and microbial contamination control is evident with the recognition that micropropagators must address pathogen and microbial contamination in vitro, and diseases and microplant failure at establishment. There is increasing interest in establishing beneficial bacterial and mycorrhizal association with microplants in vitro and in vivo.
Provides fundamental knowledge every plant scientist and student of plant pathology should know, including important historical events that gave birth to the field as well as its recent advances. Illustrates the symptoms caused by bacteria in a way that facilitates comprehension of the many different types of plant diseases that they cause. Each symptom type is presented with a detailed example of a causal agent and its characteristics, diagnostics, and mechanisms of virulence and pathogenicity. Also includes an extended discussion on the molecular mechanisms of virulence and a chapter on epidemiology and disease control.
