April 2021RNAi for Plant Improvement and Protection
by Bruno Mezzetti, Jeremy Sweet, Lorenzo Burgos
RNA interference (RNAi) has the potential to make major contributions towards sustainable crop production and protection with minimal environmental impacts compared to other technologies. RNAi is being developed and exploited both within plants (i.e. host-induced gene silencing, HIGS) and/or as topical applications (e.g. spray-induced gene silencing, SIGS) for targeting pest and pathogen genes and for manipulating endogenous gene expression in plants. Chapters by international experts review current knowledge on RNAi, methods for developing RNAi systems in GM plants and applications for crop improvement, crop production and crop protection. Chapters examine both endogenous systems in GM plants and exogenous systems where interfering RNAs are applied to target plants, pests and pathogens. The biosafety of these different systems is examined and methods for risk assessment for food, feed and environmental safety are discussed. Finally, aspects of the regulation of technologies exploiting RNAi and the socio-economic impacts of RNAi technologies are discussed.

BiotechnologyJuly 2004Introgression from Genetically Modified Plants into Wild Relatives
by Edited by Hans C M den Nijs, Detlef Bartsch, Jeremy Sweet
Introgression is the incorporation of a gene from one organism complex into another as a result of hybridization. A major concern with the use of genetically modified plants is the unintentional spread of the new genes from cultivated plants to their wild relatives and the subsequent impacts on the ecology of wild plants and their associated flora and fauna.The book reviews these issues, focusing on the ecological and evolutionary effects of introducing GM cultivars. It presents current knowledge of crop-wild relatives hybridization and introgression, and the measurement and prediction of their consequences. As a result it represents a major contribution to the debate about the risks of GM crops and measures, such as post commercialisation monitoring, required to determine the longer term impacts of GM crops on ecosystems.The book presents edited and revised presentations given at a conference of the same name, organised in January 2003 by the University of Amsterdam (Netherlands) and the Robert Koch Institute (Germany), on behalf of the European Science Foundation funded program for Assessment of the Impacts of Genetically Modified Plants (AIGM ).

Veterinary medicine: large animals (domestic / farm)April 2008Mathematical Modelling in Animal Nutrition
by Edited by James (Jim) France, Ermias Kebreab, A T G Elzebroek, K Wind.
Mathematical modelling is increasingly applicable to the practical sciences. Here, mathematical approaches are applied to the study of mechanisms of digestion and metabolism in primary animal species. Farmed animals - ruminants, pigs, poultry and fish are comprehensively covered, as well as sections on companion animals. Common themes between species, such as energy and amino acid metabolism, are explored with a worldwide approach. Leading researchers from around the world have contributed to France and Kebreab's volume to provide an integrated approach to mathematical modelling in animal nutrition.

Dragon fruit (pitaya) is a perennial climbing cactus, native to the tropical areas of North, Central and South America. It is suited to tropical and subtropical regions and is commercially grown in an increasing number of countries, including Israel, Australia and the USA. Dragon fruit generates considerable consumer interest because of its exotic appearance and potential health benefits. The fruit is rich in nutrients and phytochemical compounds. It can be eaten fresh or used in the preparation of juices, jellies, jams, etc. The natural bioactive compounds in pitaya have the potential to be exploited in food, pharmaceutical and cosmetic industries. Increasingly cultivated worldwide, the plant is drought-resistant, easily adapts to light intensity and high temperatures, and has a tolerance to a wide range of soil salinities. With ongoing global warming, dragon fruit has great potential as a new crop for many more countries. This book is a compilation of the current state of knowledge on dragon fruit physiology, cultivation, production technology, postharvest management and processing, and is written by leading international authors.

September 2021Spices, Scents and Silk
Catalysts of World Trade
by James F Hancock
Spices, scents and silks were at the center of world trade for millennia. Through their international trade, humans were pushed to explore and then travel to the far corners of the earth. Almost from their inception, the earliest great civilizations - Egypt, Sumer and Harappa - became addicted to the luxury products of far off lands and established long-reaching trade networks. Over time, great powers fought mightily for the kingdoms where silk, spices and scents were produced. The New World was accidentally discovered by Columbus in his quest for spices. What made trade in these products so remarkable was that the plants producing them grew in very restricted areas of the world, distant from the wealthy civilizations of northern Africa, Greece and Europe. These luxuries could be carried from mysterious locations on the backs of camels or in the holds of ships for months on end, and arrived at their final destination in nearly perfect condition. Once the western world discovered the intoxicating properties of these products, their procurement became a dominant force in the world economy. Nothing else compared with their possible profit returns. In this book, eminent horticulturist and author James Hancock examines the origins and early domestication and culture of spices, scents and silks and the central role these exotic luxuries played in the lives of the ancients. The book traces the development of the great international trade networks and explores how struggles for trade dominance and demand for such luxuries shaped the world.

Science & MathematicsJanuary 2021Tropical Tuber Starches
Structural and Functional Characteristics
by S N Moorthy, M S Sajeev, R P K Ambrose, R J Anish
This book provides comprehensive and up-to-date knowledge relating to the morphological, structural, and functional characteristics of tuber starches, particularly in relation to their applications in food and industry. In recent years there has been significant progress and extensive research conducted on tropical root starches and especially on some of the lesser known tuber crop starches. There has also been a shift towards using biomaterials in place of synthetic materials in various applications. As researchers investigate the availability of natural products with similar properties, starch has been identified as a reliable alternative to these synthetic materials. Reflecting the growing body of research, Tropical Tuber Starches: - Explores the structure, properties and applications of tropical root and tuber starches (cassava, sweet potato, aroids, yams and other minor tuber crops) - Includes a chapter on the methodology for starch characterisation - Covers patents on starch-based products and the commercial potential of tropical root starches A valuable resource for researchers and students, plant breeders, and commercial producers working with, or considering working with, tropical tuber starches. Table of Contents 1: Introduction - Tropical Tuber Crops and Their Importance 2: Starch - General Considerations 3: Cassava 4: Sweet Potato 5: Aroids 6: Yams 7: Other Starches 8: Starch Modifications 9: Applications of Tuber Starches 10: Characterization and Analysis of Starches 11: Conclusions and Future Prospects
