Plant Innate Immunity

The volume III of the book presents the ways and means to manipulate the signals and signaling system to enhance the expression of plant innate immunity for crop disease management. It also describes bioengineering approaches to develop transgenic plants expressing enhanced disease resistance using plant immunity signaling genes. It also discusses recent commercial development of biotechnological products to manipulate plant innate immunity for crop disease management. Engineering durable nonspecific resistance to phytopathogens is one of the ultimate goals of plant breeding. However, most of the attempts to reach this goal fail as a result of rapid changes in pathogen populations and the sheer diversity of pathogen infection mechanisms. Recently several bioengineering and molecular manipulation technologies have been developed to activate the ‘sleeping’ plant innate immune system, which has potential to detect and suppress the development of a wide range of plant pathogens in economically important crop plants. Enhancing disease resistance through altered regulation of plant immunity signaling systems would be durable and publicly acceptable. Strategies for activation and improvement of plant immunity aim at enhancing host’s capability of recognizing invading pathogens, boosting the executive arsenal of plant immunity, and interfering with virulence strategies employed by microbial pathogens. Major advances in our understanding of the molecular basis of plant immunity and of microbial infection strategies have opened new ways for engineering durable resistance in crop plants.

This book presents the ways and means to switch on plant immune signaling systems using PAMP-PIMP-PRR signaling complex for crop disease management. It also describes bioengineering approaches to develop transgenic plants expressing enhanced disease resistance using genes encoding PAMPs, PRRs and transcription factors and genes involved in generation of PIMPs/HAMPs. It also discusses recent commercial development of PAMP products to switch on plant innate immunity for crop disease management. These unique approaches have been described with more than 100 figures and illustrations and these would make this book attractive for researchers and students to buy this book.

Plant innate immunity is a potential surveillance system of plants and is the first line of defense against invading pathogens. The immune system is a sleeping system in unstressed healthy plants and is activated on perception of the pathogen-associated molecular patterns (PAMP; the pathogen’s signature) of invading pathogens. The PAMP alarm/danger signals are perceived by plant pattern-recognition receptors (PRRs). The plant immune system uses several second messengers to encode information generated by the PAMPs and deliver the information downstream of PRRs to proteins which decode/interpret signals and initiate defense gene expression. This book describes the most fascinating PAMP-PRR signaling complex and signal transduction systems. It also discusses the highly complex networks of signaling pathways involved in transmission of the signals to induce distinctly different defense-related genes to mount offence against pathogens.

Plant innate immunity is a collective term to describe a complex of interconnected mechanisms that plants use to withstand potential pathogens and herbivores. The last decade has seen a rapid advance in our understanding of the induction, signal transduction and expression of resistance responses to oomycetes, fungi, bacteria, viruses, nematodes and insects. This volume aims at providing an overview of these processes and mechanisms.Edited by Jean-Claude Kader and Michel Delseny and supported by an international Editorial Board, Advances in Botanical Research publishes in-depth and up-to-date reviews on a wide range of topics in plant sciences. Multidisciplinary reviews written from a broad range of scientific perspectives For over 40 years, series has enjoyed a reputation for excellence Contributors internationally recognized authorities in their respective fields

Plants constantly face many kinds of abiotic and biotic stresses. One of the major threats is from many plant fungal, oomycete, viral, bacterial and nematode pathogens. Plant diseases caused by these pathogens reduce crop yield by 10-15% worldwide every year. Throughout the human history, plant diseases are responsible for many famines including the infamous Irish Potato Famine. Besides the negative impact on the yield, the quality of the infected crop will be adversely affected and the toxins produced by plant pathogens pose threat to human health. During the co-evolution between plants and pathogens, plants developed elegant defense system against pathogen infection and plant pathogens deploy a variety of strategies to suppress plant innate immunity. A deeper understanding the molecular mechanisms on the activation of plant defense in plants and suppression of plant defense by plant pathogens will be crucial to develop effective ways to minimize the detrimental effects from plant diseases on human beings. This Research Topic aims to increase our understanding on the molecular interactions between plants and pathogens.

This book has been cunningly designed to provide an overview of our current knowledge about the innate immune systems of these three types of organisms. It not only covers the innate immune mechanisms and responses of such diverse organisms as plants, Cnidaria, Drosophila, urochordates and zebrafish, but also the major receptor systems in mammalians and humans. It delves too into the central defense mechanisms, antimicrobial peptides and the complement system.
