Induced resistance offers the prospect of broad spectrum, long-lasting and potentially environmentally-benign disease and pest control in plants. Induced Resistance for Plant Defense 2e provides a comprehensive account of the subject, encompassing the underlying science and methodology, as well as research on application of the phenomenon in practice. The second edition of this important book includes updated coverage of cellular aspects of induced resistance, including signalling and defenses, costs and trade-offs associated with the expression of induced resistance, research aimed at integrating induced resistance into crop protection practice, and induced resistance from a commercial perspective. Current thinking on how beneficial microbes induce resistance in plants has been included in the second edition. The 14 chapters in this book have been written by internationally-respected researchers and edited by three editors with considerable experience of working on induced resistance. Like its predecessor, the second edition of Induced Resistance for Plant Defense will be of great interest to plant pathologists, plant cell and molecular biologists, agricultural scientists, crop protection specialists, and personnel in the agrochemical industry. All libraries in universities and research establishments where biological, agricultural, horticultural and forest sciences are studied and taught should have copies of this book on their shelves.

Plant diseases worldwide are responsible for billions of dollars worth of crop losses every year. With less agrochemicals being used and less new fungicides coming on the market due to environmental concerns, more effort is now being put into the use of genetic potential of plants for pathogen resistance and the development of induced or acquired resistance as an environmentally safe means of disease control. This comprehensive book examines in depth the development and exploitation of induced resistance. Chapters review current knowledge of the agents that can elicit induced resistance, genomics, signalling cascades, mechanisms of defence to pests and pathogens and molecular tools. Further chapters consider the topical application of inducers for disease control, microbial induction of pathogen resistance, transgenic approaches, pathogen population biology, trade offs associated with induced resistance and integration of induced resistance in crop protection. The book concludes with a consideration of socio-economic drivers determining the use of induced resistance, and the future of induced resistance in crop protection.

Plant Defense provides an overview of all major aspects of plant defence, including defence against pathogens, parasites, and invertebrate and vertebrate herbivores. The book looks at defense mechanisms including structural and chemical defences, and constitutive and inducible defences. Including details of how plants 'sense' attack and how this is communicated within the plant and also to neighbouring plants, how plants coordinate defence responses to simultaneous multiple attacks, and the energy and resources expended by a plant in maintaining and implementing its defence systems.

This book investigates the induced responses of plants to herbivores and to diseases. Plant pathologists and entomologists will find that their disciplines have a lot in common when it comes to the interest in the transduction signals of plants that mediate induced responses. Induced Plant Defenses Against Pathogens and Herbivores will allow these two disciplines to converse and learn from their similarities and differences.

Plants have developed very sophisticated mechanisms to combat pathogens and pestsusingtheleastamountofreservedorgeneratedenergypossible. Theydothis by activating major defense mechanisms after recognition of the organisms that are considered to be detrimental to their survival; therefore they have been able to exist on Earth longer than any other higher organisms. It has been known for the past century that plants carry genetic information for inherited resistance against many pathogenic organisms including fungi, bacteria, and viruses, and that the relationship between pathogenic organisms and hosts plants are rather complex and in some cases time dependent. This genetic information has been the basis for breeding for resistance that has been employed by plant breeders to develop better-yielding disease resistant varieties, some of which are still being cultivated. Single gene resistance is one type of resistance which has been extensively studied by many research groups all around the world using biotechnological methodologies that have been the subject of many books and journal articles; therefore, it is beyond the scope of this book. This type of resistance is very effective, although it can be overcome by the pressure of pathogenic organisms since it depends on interaction of a single elicitor molecule from the pathogen with a single receptor site in the host.

Plants are members of complex communities and interact both with antagonists and beneficial organisms. An important question in plant defense-signaling research is how plants integrate signals induced by pathogens, insect herbivores and beneficial microbes into the most appropriate adaptive response. Molecular and genomic tools are now being used to uncover the complexity of the induced defense signaling networks that have evolved during the arms races between plants and the other organisms with which they intimately interact. To understand the functioning of the complex defense signaling network in nature, molecular biologists and ecologists have joined forces to place molecular mechanisms of induced plant defenses in an ecological perspective. In this Research Topic, we aim to provide an on-line, open-access snapshot of the current state of the art of the field of induced plant responses to microbes and insects, with a special focus on the translation of molecular mechanisms to ecology and vice versa.

Development of disease management approaches based on environmental stewardship is a growing trend in turfgrass industry. Integration of host defense response elicitors into disease management program is one of the most innovative potential approaches to turf disease management. In order to support the wide-adoption of this approach to manage turfgrass disease, key questions, such as how exogenous application of plant resistance activators induce defense response in perennial ryegrass and whether such induced resistance is effective against fungal infections is warranted. However, how systemic defense response operates in perennial ryegrass is virtually unexplored, and only recently several pathogenesis-related (PR) genes have been identified and sequenced. Regardless of plant-pathogen interaction type, compatible or incompatible, products of several of these genes are known to accumulate to a higher degree and play a pivotal role in plant defense against pathogen infection. Incompatible interactions are typically characterized by more rapid and higher accumulation of defense-related metabolites/products compared to compatible interactions. The primary objective of this thesis research was to identify different components of induced resistance (IR) elicited by plant defense activators in perennial ryegrass, including pre-invasive defense reactions such as, papillae development, and post-invasive host responses including hypersensitive-like cell death and patterns of PR-gene expression following infection by Magnaporthe oryzae, a fungal pathogen causing gray leaf spot disease. Investigation on the systemic acquired resistance (SAR) in perennial ryegrass revealed that M. oryzae infection causes accumulation of endogenous free salicylic acid (SA) in the leaf blades. Application of known SAR activators such as SA and BTH (benzothiadiazole) suppressed gray leaf spot disease with concomitant enhancement of expression levels of PR-3.1 and PR-5. Additionally, investigation on induced systemic resistance (ISR) with the biological control agent Bacillus amyloliquefaciens FZB42, a plant beneficial rhizobacterium, and its metabolite surfactin, a cyclic lipopeptide with plant defense stimulatory activity, revealed that H2O2 generating cell components play a key role in suppressing gray leaf spot on perennial ryegrass through activation of both pre- and post-invasive defense responses. Additionally, soil amendment with silicon formulation resulted in papillae-associated penetration resistance as well as enhanced defense-related gene expression in perennial ryegrass, thereby, suppressing gray leaf spot disease. The findings from these research projects contributed to enhancing our understanding of the multifaceted systemic defense responses in perennial ryegrass, which share similarities with other well-studied members of Gramineae family such as, barley, rice and wheat. Application of well known SAR, ISR and CIR (chemically induced resistance) activators against M. oryzae holds the potential to be an important component in the gray leaf spot disease management strategy.

Induced or acquired resistance to disease in plants has been known for many years, but the phenomenon was studied in only a few laboratories until about a decade ago. Since then, there has been an increasing interest in induced resistance as a new, environmentally safe means of disease control, as well as a model for the study of the genes involved in host defence and the signals that control them. This increased interest led the editors of Induced Resistance to Disease in Plants to collect and summarise much of the current and older literature on the topic in a single volume. Each chapter covers its topic as comprehensively as possible, thus serving as a solid introduction to the literature, as well as expressing its writer's own views on the state of research in the area and giving an indication of where future research may lead. Induced Resistance to Disease in Plants addresses the biology of induced resistance in legumes, solanaceae, cucurbits and monocots, since these are the families that have received the most attention, followed by a discussion of the molecular basis of induced resistance, its genetic and evolutionary significance, and practical applications in disease control. The book will provide a background for those commencing work in the area, as well as a source of information for established workers who wish to learn about other areas of induced resistance.
