Overzealous and indiscriminate use of many synthetic pesticides during recent decades in the control of plant pests has resulted in a number of environmental and toxicological problems. Reducing the release of synthetic chemicals into the environment requires that alternative sources of chemicals are developed that can be used safely in the management of plant pests. Botanical antimicrobials derived from plants are currently recognised as biodegradable, systemic, eco-friendly and non-toxic to mammals and are thus considered safe. Their modes of action against pests are diverse. Natural compounds are well suited to organic food production in industrialised countries and can play greater roles in the protection of food crops in developing countries Some plant based antimicrobials (e.g. neem products, pyrethoids and essential oils) are already used to manage pest populations on a large scale. Plant scientists and agriculturists now devote significant attention to discovery and further development and formulation of novel plant products with antimicrobial activity.This book is the first to bring together relevant aspects of the basic and applied sciences of natural pesticides and discussed modern trends in the use of natural products in pest management.

This volume sits at the cross-roads of a number of areas of scientific interest that, in the past, have largely kept themselves separate - agriculture, forestry, population genetics, ecology, conservation biology, genomics and the protection of plant genetic resources. Yet these areas also have a lot of common interests and increasingly these independent lines of inquiry are tending to coalesce into a more comprehensive view of the complexity of plant-pathogen associations and their ecological and evolutionary dynamics. This interdisciplinary source provides a comprehensive overview of this changing situation by identifying the role of pathogens in shaping plant populations, species and communities, tackling the issue of the increasing importance of invasive and newly emerging diseases and giving broader recognition to the fundamental importance of the influence of space and time (as manifest in the metapopulation concept) in driving epidemiological and co-evolutionary trajectories.

Plasticity in Plant-Growth-Promoting and Phytopathogenic Bacteria brings together the expertise of a panel of researchers from around the world to provide comprehensive up-to-date reviews on the most interesting aspects of genomic and phenotypic plasticity in plant-beneficial and phytopathogenic bacteria.

Plasticity in Plant-Growth-Promoting and Phytopathogenic Bacteria is recommended for all microbiology and plant biology laboratories.

Plant diseases, extreme weather caused by climate change, drought and an increase in metals in soil are amongst the major limiting factors of crop production worldwide. They devastate not only food supply but also the economy of a nation. Keeping in view of the global food scarcity, there is, an urgent need to develop crop plants with increased stress tolerance so as to meet the global food demands and to preserve the quality of our planet. In order to do this, it is necessary to understand how plants react and adapt to stress from the genomic and proteomic perspective. Plants adapt to stress conditions by activation of cascades of molecular mechanisms, which result in alterations in gene expression and synthesis of protective proteins/compounds. From the perception of the stimulus to transduction of the signal, followed by an appropriate response, the plants employ a complex network of primary and secondary messenger molecules. Cell signaling is the component of a complex system of communication that directs basic cellular activities and synchronizes cell actions. Cells exercise a large number of noticeably distinct signaling pathways to regulate their activity. In order to contend with different environmental adversities plants have developed a series of mechanisms at the physiological, cellular and molecular level. This two volume set takes an in-depth look at the Stress Signaling in Plants from a uniquely genomic and proteomics perspective. Stress Signaling in Plants offers a comprehensive treatise on the Chapter, covering all of the signaling pathways and mechanisms that have been researched so far. Each chapter provides in-depth explanation of what we currently know of a particular aspect of stress signaling and where we are headed. All authors have currently agreed and abstracts have been complied for the first volume, due out midway through 2012. We aim to have the second volume out at the beginning of 2013.

Isoprenoids are important in primary and secondary metabolism. They have implications in a myriad of physiological processes notably in plants, microorganisms and parasites, and biological activities at the cellular, organism, and ecosystem levels. The importance of isoprenoids in various areas of the scientific world has spurred intense research worldwide. Also their role in "nutraceuticals" has stimulated scientific curiosity. Literature on isoprenoids is widely scattered in journals with quite differing readerships and geographic distribution. A comprehensive book on isoprenoids does not exist. Isoprenoid Synthesis in Plants and Microorganisms: New Concepts and Experimental Approaches fills this gap by presenting the latest and the most applicable information on isoprenoids. The most recent TERPNET conference serves as the backdrop and provides much of the inspiration for the topics covered in the book. Additional topics of interest are covered as well, making Isoprenoid Synthesis in Plants and Microorganisms: New Concepts and Experimental Approaches the most comprehensive review of isoprenoid synthesis to date.

A comprehensive manual of phytobacteriology, this work is heavily illustrated with over 200 colour photographs and line illustrations. It begins by outlining the history and science of bacteriology and gives an overview of the diversity and versatility of complex bacteria. It then explains the characterization, identification and naming of complex bacteria, and explores how bacteria can cause disease and how plants react to such disease. The book also discusses the economic importance of bacterial diseases as well as strategies for their control and the reduction of crop losses. It concludes with 50 examples of plant pathogenic bacteria and the diseases that they cause.

This volume contains a series of contributions from established European researchers which consider aspects of molecular variability in fungal pathogens. Chapters are derived from a workshop held in Evian, France, in September 1997, supported by the EU Concerted Action Air 3-CT94-2448. The volume is divided into three sections. The first includes contributions which consider and review the major mechanisms involved, the second details specific studies on variability in populations of different fungal pathogens, and the third includes contributions on methods for interpreting such variability. The workshop was intended to bring together methods and understanding from a wide range of fungal pathogens, and this is reflected in the volume where individual contributions include case studies and reviews of populations of fungi pathogenic on insects and nematodes as well as plant and human pathogens. The combination of mechanisms, characterization and interpretation across a wide range of applied mycology makes this a significant general text for those working on molecular characterization. The broad spectrum of topics provides a multidisciplinary reference source within mycology and the book will be suitable for postgraduate students and research scientists in applied mycology, including plant pathology, medical mycology and biological control.

Plant-parasitic nematodes devastate crops worldwide, in turn impacting international trade, social and economic development. Effective control of nematodes is essential for crop protection, and requires an understanding of nematode biology, taxonomy, population dynamics and sampling methods. Providing a broad introduction to nematodes as plant parasites, this book begins by describing nematodes by genera, and builds on this foundation to detail nematode biology and pest management, including biological and chemical control. Chapters are authored by international experts and enhanced by extensive illustrations and focus boxes. Fully updated throughout, this new edition is an essential resource for postgraduate students, extension officers, researchers and crop protection scientists.
