Fungi are important plant pathogens which can be responsible for significant yield losses and in some cases, even complete losses in the infected fields or crops. In many cases, fungi coexist in symbiotic association with plant roots and provide benefits to the plants. Therefore, understanding the diversity of the fungi that interact with plants both in symbiotic and pathogenic interaction is critical to harness the beneficial species and strains and control the pathogenic species and strains. Developments in the field of molecular biology move very fast comparatively, books covering the various aspects of molecular biology of fungi are always welcomed by scientists. Features recent trends in phytomycology and fungal biology studies using modern molecular tools. Contains information on improved methods in genetics, genomics and metabolomics.

"Plant Breeding Reviews" presents state-of-the-art reviews on plant genetics and the breeding of all types of crops by both traditional means and molecular methods. Many of the crops widely grown today stem from a very narrow genetic base; understanding and preserving crop genetic resources is vital to the security of food systems worldwide. The emphasis of the series is on methodology, a fundamental understanding of crop genetics, and applications to major crops. It is a serial title that appears in the form of one volume per year. Articles perform the function of collecting, comparing, and contrasting the primary journal literature in order to form an overview of the topic. This detailed analysis aims to bridge the gap between the specialized researcher and the broader community of plant scientists. The series is particularly important at this time when the methods of molecular biology are leading to genetically-engineered crops, and when the supply of wild varieties of many crops are threatened.

In recent decades, the governance of the environment in agri-food systems has emerged as a crucial challenge. A multiplicity of actors have been enrolled in this process, with the private sector and civil society progressively becoming key components in a global context often described as neoliberalization. Agri-environmental governance (AEG) thus gathers a highly complex assemblage of actors and instruments, with multiple interrelations. This book addresses this complexity, challenging traditional modes of research and explanation in social science and agri-food studies. To do so, it draws on multiple theoretical and methodological insights, applied to case studies from Asia, Europe, Africa, and the Americas. It elaborates an emergent approach to AEG practices as assemblages, looking at the coming-together of multiple actors with diverse trajectories and objectives. The book lays the foundations for an encompassing theoretical framework that transcends pre-existing categories, as well as promoting innovative methodologies, which integrate the role of social actors - including scientists - in the construction of new assemblages. The chapters define, first, the multiplicities and agencies inherent to AEG assemblages. A second set tackles the question of the politics in AEG assemblages, where political hierarchies interweave with economic power and the search for more democratic and participative approaches. Finally, these insights are developed in the form of assemblage practice and methodology. The book challenges social scientists to confront the shortcomings of existing approaches and consider alternative answers to questions about environmental governance of agri-food systems.

Plants are frequently exposed to unfavorable and adverse environmental conditions known as abiotic stressors. These factors can include salinity, drought, heat, cold, flooding, heavy metals, and UV radiation which pose serious threats to the sustainability of crop yields. Since abiotic stresses are major constraints for crop production, finding the approaches to enhance stress tolerance is crucial to increase crop production and increase food security. This book discusses approaches to enhance abiotic stress tolerance in crop plants on a global scale. Plants scientists and breeders will learn how to further mitigate plant responses and develop new crop varieties for the changing climate.

Global climate change affects crop production through altered weather patterns and increased environmental stresses. Such stresses include soil salinity, drought, flooding, metal/metalloid toxicity, pollution, and extreme temperatures. The variability of these environmental conditions pared with the sessile lifestyle of plants contribute to high exposure to these stress factors. Increasing tolerance of crop plants to abiotic stresses is needed to fulfill increased food needs of the population. This book focuses on methods of improving plants tolerance to abiotic stresses. It provides information on how protective agents, including exogenous phytoprotectants, can mitigate abiotic stressors affecting plants. The application of various phytoprotectants has become one of the most effective approaches in enhancing the tolerance of plants to these stresses. Phytoprotectants are discussed in detail including information on osmoprotectants, antioxidants, phytohormones, nitric oxide, polyamines, amino acids, and nutrient elements of plants. Providing a valuable resource of information on phytoprotectants, this book is useful in diverse areas of life sciences including agronomy, plant physiology, cell biology, environmental sciences, and biotechnology.

Volatile (essential) oil crops yield a wide range of products - fresh and dried herbs, oils and oil components and various oleoresins. Changing lifestyles in developed countries have led to dramatic increases in demand for these products, particularly over the last decade. More varied use has been made of oils and herbs in cooking, and oil components are now being regarded as safe alternatives to synthetic food additives and crop protection substances.

The surge in demand for these produces has encouraged a number of temperate and mediterranean countries to evaluate a range of volatile oil-bearing species as alternative crops. This has resulted in a rapid expansion in the scientific and technical literature on culinary and medicinal herbs.

"Volatile Oil Crops" draws much of this literature together for the first time. It reviews the basic botany, physiology and biochemistry of the major species and then analyses the genetics of oil composition. The effects of oils on a wide range of organisms are discussed and the book surveys the biotechnological methods which can be employed in the laboratory production of oils. It concludes with a full analysis of the world trade in the products of volatile oils.
