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.

There is a scarcity of detailed information regarding the ecophysiology of root systems and the way root system functioning is affected by both internal and external factors. Furthermore, global climate change is expected to increase the intensity of climate extremes, such as severe drought, heat waves and periods of heavy rainfall; in addition other stresses such as salinization of soils are increasing world-wide. Recently an increasing awareness has developed that understanding plant traits will play a major role in breeding of future crop plants. For example, there is increasing evidence that the traits of root systems are defined by the properties of individual roots. However, further knowledge on the functional importance of root segments and the molecular/physiological mechanisms underlying root system functioning and persistence is needed, and would specifically allow modifying (crop) root system functionality and efficiency in the future. Another major gap in knowledge is localized at the root-soil interface and in regard to the potential adaptive plasticity of root-rhizosphere interactions under abiotic stress and/or competition. It is currently unknown whether adaptations in microbe communities occur, for example due to modified exudation rates, and what are the subsequent influences on nutrient mobilization and uptake. Furthermore, uncovering the mechanisms by which roots perceive neighboring roots may not only contribute to our understanding of plant developmental strategies, but also has important implications on the study of competitive interactions in natural communities, and in optimizing plant performance and resource use in agricultural and silvicultural systems. In this Research Topic, we aimed to provide an on-line, open-access snapshot of the current state of the art of the field of root ecology and physiology, with special focus on the translation of root structure to function, and how root systems are influenced by interplay with internal and external factors such as abiotic stress, microbes and plant-plant interaction. We welcomed original research papers, but reviews of specific topics, articles formulating opinions or describing cutting-edge methods were also gladly accepted.

Scientists, within a wide field, ranging from applied forestry and agriculture to physiology, ecology and the environmental sciences, are today more than ever involved in root and mycorrhizal research. New problem-oriented research fields have arisen such as the effects of fertilizers and pesticides, forest management and regeneration etc. At a time when root research is expanding into different areas, it is much more difficult for the root scientist to penetrate all the new information appearing in literature. The contributors of this volume are leading scientists from different fields of root research. The ISRR-symposium in Uppsala clearly demonstrated that there are new techniques in progress, in particular with regards to video recording of plant root systems and digital image processing. The main objectives of the symposium were (i) to provide a forum for communication between scientists from different disciplines working with root research problems, (ii) to contribute to an expansion of root studies into new areas, (iii) to use current estimates of root turnover for charting the upper and lower limit of below-ground production, and (iv) to spread knowledge of new findings and techniques of the importance of root research. This book is aimed at serving as a vehicle for improving the coherence of root research, for harmonizing methods and establishing overall objectives and gaps in the knowledge of rhizosphere dynamics.

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.

Root feeders have been classified as agricultural pests but can be used as biological control agents against invasive species and can affect community dynamics of plants, soil micro-organisms and populations of above ground organisms. This book presents a review of knowledge on root herbivores and illustrates their importance within ecosystems.

The root is the organ that functions as the interface between the plant and the earth environment. Many human management practices involving crops, forests and natural vegetation also affect plant growth through the soil and roots. Understanding the morphology and function of roots from the cellular level to the level of the whole root system is required for both plant production and environmental protection. This book is at the forefront of plant root science (rhizology), catering to professional plant scientists and graduate students. It covers root development, stress physiology, ecology, and associations with microorganisms. The chapters are selected papers originally presented at the 6th Symposium of the International Society of Root Research, where plant biologists, ecologists, soil microbiologists, crop scientists, forestry scientists, and environmental scientists, among others, gathered to discuss current research results and to establish rhizology as a newly integrated research area.

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.
