Book Description
International trade in high value perishables has grown enormously in the past few decades. In the developed world consumers now expect to be able to eat perishable produce from all parts of the world, and in most cases throughout the year. Perishable plant products are, however, susceptible to physical damage and often have a potential storage life of only a few days. Given their key importance in the world economy, Crop Post-Harvest Science and Technology: Perishables devotes itself to perishable produce, providing current and comprehensive knowledge on all the key factors affecting post-harvest quality of fruits and vegetables. This volume focuses explicitly on the effects and causes of deterioration, as well as the many techniques and practices implemented to maintain quality though correct handling and storage. As highlighted throughout, regular losses caused by post-harvest spoilage of perishable products can be as much as 50%. A complete understanding, as provided by this excellent volume, is therefore vital in helping to reduce these losses by a significant percentage. Compiled by members of the world-renowned Natural Resources Institute at the United Kingdom's University of Greenwich, with contributions from experts around the world, this volume is an essential reference for all those working in the area. Researchers and upper-level students in food science, food technology, post-harvest science and technology, crop protection, applied biology and plant and agricultural sciences will benefit from this landmark publication. Libraries in all research establishments and universities where these subjects are studied and taught should ensure that they have several copies for their shelves.

Book Description
Plant viruses grouped within this family have remarkable properties, prominent among which is their genomic size: Citrus tristeza virus (CTV) has the largest (19.3 kb) genome reported for a plant monopartite single-stranded RNA (+) virus. Virions are filamentous and typically flexuous particles, approximately 12 nm in diameter and 650 to 2000 nm in length, with a unique bipolar (“rattlesnake”) morphology: the major coat protein (CP) encapsidates most of the genomic RNA, with a minor CP (CPm) coating a small 5’-terminal fragment (virion tail) and other viral-encoded proteins being also incorporated to this tail. The genome is monopartite (genus Closterovirus, type member Beet yellows virus, and genus Ampelovirus, type member Grapevine leafroll-associated virus 3) or bipartite (genus Crinivirus, type member Lettuce infectious yellows virus, with at least one example of tripartite genome). The genomic RNA (or RNA1 in criniviruses) directs translation of the two 5’-proximal ORFs (via a peculiar ribosomal frameshift mechanism and proteolytic processing) that encode replication-related components, with the 3’-proximal ORFs encoding proteins expressed from 3’-coterminal subgenomic RNAs. A genomic signature of members of the family Closteroviridae is the presence of a five-gene block of proteins involved in virion assembly and movement that, in addition to the CP and CPm, includes a small transmembrane protein, a homologue of the HSP70 class of heat-shock proteins and a diverged CP. Members of this family encode suppressors of RNA silencing differing in number (up to three in CTV), and in mode of action: intracellular, intercellular, or both. In this same context Sweet potato chlorotic stunt virus codes for a singular suppressor: an RNase III that catalyzes cleavage of the small interfering RNAs mediating RNA silencing. Host range is usually narrow and, in order to expand it, some member(s) of the family, illustrated by the case of CTV, have evolved by acquiring multiple non-conserved genes. Virion accumulation is restricted to the phloem, with aphids, mealybugs and whiteflies (depending on the genus) operating as natural vectors. Disease symptoms may be expressed in leaves, fruits and trunk of the woody hosts.

Book Description
This volume offers a comprehensive coverage of the general principles and recent advances in fungicide resistance. It describes the development, mechanisms, monitoring, and management of resistance and covers the most important group of fungicides that have caused resistance on various crops. An historical review of fungicide resistance over the past 40 years sets the scene for up-to-date basic information on mode of action, as well as the genetics, mechanisms, and evolution of resistance. Monitoring for resistance, including the latest developments in molecular diagnostics, moves readers into the practical aspects of resistance management, which is dealt with through a series of case studies outlining fungicide-use strategies on several key crops. The chapters reflect the experience of authors internationally recognised for their significant contributions to fungicide resistance research. The majority of crop diseases are caused by fungal pathogens, and disease control relies heavily on chemically synthesized fungicides. However, modern fungicides often encounter the problem of resistance development in target pathogens. Thus pathogen resistance to fungicides is an important factor that causes loss of yield and quality of crops. It often threatens biosecurity through the decrease of fungicide efficacy in the fields. To manage fungicide resistance successfully will require the promotion of integrated disease management, involving not just chemical fungicides, but also host plant resistance, agronomic factors, and reliable biological control agents where these are available. Well referenced throughout, the book offers a comprehensive account of resistance, which will be useful as a source of material for lecturers and for both industrial and academic scientists involved in fungicide resistance research. It is also a valuable sourcebook for students.

Book Description
Addressing everything from the details of everyday life to recreation and warfare, this two-volume work examines the social, political, intellectual, and material culture of the American "Old West," from the California Gold Rush of 1849 to the end of the 19th century. What was life really like for ordinary people in the Old West? What did they eat, wear, and think? How did they raise their children? How did they interact with government? What did they do for fun? This encyclopedia provides readers with an engaging and detailed portrayal of the Old West through the examination of social, cultural, and material history. Supported by the most current research, the multivolume set explores various aspects of social history—family, politics, religion, economics, and recreation—to illuminate aspects of a society's emotional life, interactions, opinions, views, beliefs, intimate relationships, and connections between the individual and the greater world. Readers will be exposed to both objective reality and subjective views of a particular culture; as a result, they can create a cohesive, accurate impression of life in the Old West during the second half of the 1800s.

Book Description
Although the decades following World War II stand out as an era of rapid growth and construction in the United States, those years were equally significant for large-scale destruction. In order to clear space for new suburban tract housing, an ambitious system of interstate highways, and extensive urban renewal development, wrecking companies demolished buildings while earthmoving contractors leveled land at an unprecedented pace and scale. In this pioneering history, Francesca Russello Ammon explores how postwar America came to equate this destruction with progress. The bulldozer functioned as both the means and the metaphor for this work. As the machine transformed from a wartime weapon into an instrument of postwar planning, it helped realize a landscape-altering “culture of clearance.” In the hands of the military, planners, politicians, engineers, construction workers, and even children’s book authors, the bulldozer became an American icon. Yet social and environmental injustices emerged as clearance projects continued unabated. This awareness spurred environmental, preservationist, and citizen participation efforts that have helped to slow, though not entirely stop, the momentum of the postwar bulldozer.

Book Description
Halophytes for Food Security in Dry Lands addresses the concerns surrounding global food scarcity, especially focusing on those living in arid and dry lands The book touches on food crises in dry regions of the world and proposes halophytes as an alternate source of consumption for such areas. Halophytes, those plants that thrive in saline soil and provide either food source options themselves, or positively enhance an eco-system's ability to produce food, and are thus an important and increasingly recognized option for addressing the needs of the nearly 1/6 of the world's population that lives in these arid and semi-arid climates. Including presentations from the 2014 International Conference on Halophytes for Food Security in Dry Lands, this book features insights from the leading researchers in the subject. It is a valuable resource that includes information on the nutritional value of halophytes, their genetic basis and potential enhancement, adaption of halophytes, and lessons learned thus far. - Provides comprehensive coverage of the importance and utilization of halophytes to compensate the demand of food in whole world especially in the dry regions - Contains insights from ecological to molecular fields - Includes edible halophytes as well as those that enhance food-producing eco-systems - Presents information for improving abiotic stress tolerance in plants
