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.

Root research under natural field conditions is still a step-child of science. The reason for this is primarily methodological. The known methods are tedious, time consuming, and the accuracy of their results is often not very great. Many research workers have been discouraged by doing such root studies. The need for more information on the development and distribution of plant roots in different soils under various ecological conditions is, however, obvious in many ecological disciplines. Especially the applied botanical sciences such as agriculture, horticulture, and forestry are interested in obtaining more data on plant roots in the soil. This book will give a survey of existing methods in ecological root research. Primarily field methods are presented; techniques for pot experiments are described only so far as they are important for solving ecological problems. Laboratory methods for studying root physiology are not covered in this book. Scientific publications on roots are scattered in many different journals published all over the world. By working through the international root literature I found that about ten thousand papers on root ecology have been published at the present. This is not very much compared with the immense literature on the aboveground parts of the plants, but is, however, too much to cite in this book.

Temperate forests cover large areas of Europe and perform a number of important functions such as the regulation of energy and matter, production of wood and other resources, and conservation of biodiversity and habitats; they also have special signi?cance in social and cultural contexts. Initiated in 1960s, the ?rst International Biological Program (IBP) focused on ‘‘the biological basis of productivity and human welfare. ’’ As the German contribution to the IBP, ecosystem research has been carried out since 1966 in the Solling area (Ellenberg H. , Ecological Studies 2, 1971), an upland region in Northwest Germany. This study provided clear evidence that the stability of forest ecosystems was threatened by the high inputs of at- spheric pollutants. This promoted many interdisciplinary research programs which were coordinated by Prof. Dr. Bernhard Ulrich and the Forest Ecosystems Research Center of the University of Go ̈ttingen. This involved, in addition to the Solling site, the establishment of two other sites for long-term monitoring of ecosystem pro- ̈ cesses. The two contrasting sites were established in 1980 at Gottinger Wald on base-rich calcareous soil and in 1989 at Zierenberg on volcanic soil. These projects were funded initially by the Federal Ministry of Research and Technology (BMBF) as interdisciplinary projects under the titles: ‘‘Conditions of Stability of Forest Ecosystems’’ (1989–1993), and ‘‘Dynamics of Forest Ecos- tems’’ (1993–1998). The primary goal of these studies was to quantify the ecolo- cal condition of forests in a changing environment and element ?uxes.

Ecology is the centerpiece of many of the most important decisions that face humanity. Roots of Ecology documents the deep ancestry of this now enormously important science from the early ideas of Herodotos, Plato, and Pliny, up through those of Linnaeus and Darwin, to those that inspired Ernst Haeckel's mid-nineteenth-century neologism ecology. Based on a long-running series of regularly published columns, this important work gathers a vast literature illustrating the development of ecological and environmental concepts, ideas, and creative thought that has led to our modern view of ecology. Roots of Ecology should be on every ecologist's shelf.

This volume illustrates the complex root system, including the various essential roles of roots as well as their interaction with diverse microorganisms localized in or near the root system. Following initial chapters describing the anatomy and architecture as well as the growth and development of root systems, subsequent chapters focus on the various types of root symbiosis with bacteria and fungi in the rhizosphere. A third section covers the physiological strategies of roots, such as nitrate assimilation, aquaporins, the role of roots in plant defense responses and in response to droughts and salinity changes. The book’s final chapters discuss the prospects of applied engineering of roots, i.e., inventing new root structures or functions through genetic modification, but also with conventional breeding and manipulation of root symbionts. The budding field of root engineering is expected to promote a second green revolution.

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.

Plant microbe interaction is a complex relationship that can have various beneficial impacts on both the communities. An urgent need of today’s world is to get high crop yields in an ecofriendly manner. Utilization of beneficial and multifaceted plant growth promoting (PGP) microorganisms can solve the problem of getting enhanced yields without disturbing the ecosystem thus leading to sustainability. For this to achieve understanding of the intricate details of how the beneficial microbes form associations with the host plant and sustain that for millions of years must be known. A holistic approach is required wherein the diversity of microbes associated with plant and the network of mechanisms by which they benefit the host must be studied and utilized. ‘Plant Microbe Symbiosis – Fundamentals and Advances’ provides a comprehensive understanding of positive interactions that occur between plant and microorganisms and their utilization in the fields. The book reviews the enormous diversity of plant associated microbes, the dialog between plant-microbes-microbes and mechanisms of action of PGP microbes. Utilization of PGPRs as nutrient providers, in combating phytopathogens and ameliorating the stressed and polluted soils is also explained. Importantly, the book also throws light on the unanswered questions and future direction of research in the field. It illustrates how the basic knowledge can be amalgamated with advanced technology to design the future bioformulations.

Some pioneers in soil research such as Müller and Kubiëna were as much biologists as they were soil scientists and the legendary biologist Charles Darwin was foresighted in recognizing the earthworms as instrumental in reworking the soil, thereby forming what he called "vegetable mould". Still, soil science has largely been the realm of physicists and chemists over the past decades. Whatever the reason, this picture is rapidly changing. Until recently, research on the transport and transformation of elements in soil was often concerned with either soil biota/plant relationships or with soil structure/plant relationships, if the biota were considered at all, but very few studies explicitly took the interrelationships between soil structure and soil biota into account. The conference on Soil Structure/Soil Biota Interrelationships, held at Wageningen, The Netherlands, 24-28 November 1991, was meant to bridge that gap, focussing on methods of research, organized in three levels: features, processes and effects. The proceedings of the conference are testimony of the need to intertwine the biological, morphological, physical and chemical disciplines in soil research to understand better and forecast soil properties and processes as related to land use for agricultural and other purposes. This book should be of particular interest to soil scientists and ecologists who feel the need for a cross-disciplinary approach in soils research. It should also be a rich source of teaching material for courses in soil science and soil ecology at graduate level and above, with ample reference to studies on land use as related to agriculture and the environment.

Roots represent half of the plant body – and arguably the more interesting half. Despite its obvious importance for the whole plant, until recently our knowledge of the root apparatus was very limited, mostly due to the inadequacy of the techniques available. Recent advances in the visualization and measurement of roots have resulted in significant progress in our understanding of root architecture, growth and behaviour. In this book international experts highlight the most advanced techniques, both lab and field methods, and discuss them in detail. Measuring Roots combines academic and practical aspects of this topic, making it a universal handbook for all researchers and others interested in root-measuring methods.
