Ecology of Root Pathogens discusses the significance of fungi infecting the roots, and emphasizes the significant diseases of roots and their symptoms. This book also names the genera and species of fungi that cause diseases of roots, and classifies and characterizes the root and pathogen interaction in soil. The book describes the behavior of plant pathogenic bacteria, such as Agrobacterium, Corynebacterium, Xanthomonas, Pseudomonas, Erwinia, and Streptomyces. It also explores how plants and plant-produced stimuli affect the associated population of plant parasitic nematodes and how these plant parasitic nematodes affect higher plants in certain ways. In addition, this book discusses the morphology, classification, nomenclature, multiplication and translocation of viruses infecting the plants. It also describes the symptoms of the virus infection in roots. The book includes a discussion on the fundamentals of biological control, which include the pathosystem concept, the behavior of the soil microflora in the soil, the reservoirs for infection, the processes of pathogen decline, and the integrated effects on the decline of the pathogen. This discussion on biological control also presents the natural and artificially induced biological control. This book will be of great value to soil microbiologists and plant pathologists.

Root disease epidemics, because much of the activity takes place in soil and out of sight, pose special challenges to growers who seek to manage them and to scientists who study them. All relevant topics of root disease epidemics and their management are presented: The critical aspects of specific disease components including inoculum, host roots, mycorrhiza and the soil environment are explored. Challenges of disease assessment and the temporal and spatial aspects of epidemic development are considered, and approaches to root disease management including host resistance, chemical, biological and cultural management are discussed in detail. The book fulfills the needs of researchers, teachers, and practitioners of plant pathology.

In the course of evolution, a great variety of root systems have learned to overcome the many physical, biochemical and biological problems brought about by soil. This development has made them a fascinating object of scientific study. This volume gives an overview of how roots have adapted to the soil environment and which roles they play in the soil ecosystem. The text describes the form and function of roots, their temporal and spatial distribution, and their turnover rate in various ecosystems. Subsequently, a physiological background is provided for basic functions, such as carbon acquisition, water and solute movement, and for their responses to three major abiotic stresses, i.e. hard soil structure, drought and flooding. The volume concludes with the interactions of roots with other organisms of the complex soil ecosystem, including symbiosis, competition, and the function of roots as a food source.

Interactions between Non-Pathogenic Soil Microorganisms and Plants provides a comprehensive discussion of the non-pathogenic microorganisms associated with roots. It describes how a myriad of soil microorganisms affect plant growth, and how climatic and edaphic conditions contribute to the magnitude of microbial activity. The book is divided into 11 chapters that cover the plant-microorganism system; growth, structure, and physiology of roots; and nutrient uptake. It also explains the root exudates and exudation; energy flow in the plant; and rhizosphere. Legume symbiosis and root nodule symbioses in non-leguminous nitrogen fixing plants are also discussed. Moreover, the book explains the mycorrhizae and the impact of climatic and edaphic conditions on soil management and plant growth. The information that the book presents serves as a useful focal point for further studies on the interactions between plants and soil microorganisms. Thus, it provides an impetus for the development of agricultural practices that could improve food production, while mitigating anthropogenic pollution of agrosytems and waste of energy resources. Students, lecturers, and research workers in plant physiology and anatomy, microbiology, soil science, general ecology, and agronomy will find this book an invaluable reference for their learning and practice.

This book investigates soil ecology and biodiversity for its ability to maintain a balance of beneficial organisms to support plant growth. This subject is discussed by a group of international authors in natural, agricultural and urban systems. The importance of biodiversity per se and, specifically, the feedbacks between the plant and soil biota in mediating soil function are emphasized. Examples are selected from allelopathy and invasive plant species along with the, hitherto overlooked, role of viruses in soil. The book is intended to provide a framework for a holistic understanding of the essential role of soil organisms in promoting plant growth.
