The papers herein are volume 2 of the proceedings of the 11th International Wheat Genetics Symposium, held in Brisbane, Australia, in 2008. The series presents the science of the genetic sciences applied to bread and durum wheats and other species.

Genetic diversity is one of the main resources sustaining human life. Food security largely depends on the availability and utilization of this diversity, which is of strategic importance for countries and companies. Conservation and utilization of biodiversity is thus currently an urgent area of global debate and concern. Barley is a major crop in the world used for food, feed and malt, and with a wide religious and ethnic importance. The crop was domesticated in Neolithic time in SW Asia and spread rapidly under cultivation to new areas. Nowadays it is one of the most widespread and widely adapted crops grown under contrasting edaphic conditions. Adaptations to new environments, different agricultural practices and selection for different uses have further added to the complex diversity pattern. Is it at all possible to give a complete picture of the diversity in a crop or wild species? Are we, by adding new technologies, only revealing parts of the diversity? Do different sets of data show similar or conflicting pictures of genetic diversity? Will the large genome size reduce the role of barley as a model organism in these current sequencing days? Or, are there still major reasons to continue to work with this beautiful crop? The aim of this book is to cover the complex issue of diversification in time and space in a single crop: barley. Leading scientists from various fields describe the entire variation pattern in different sets of characters and an attempt is made for a synthesis to a holistic picture. The book proposes ways to use the achievements of diversity studies in future research and breeding programmes.

A review of various types of whole grains, the bioactives present within them, and their health-promoting effects As rates of obesity and other chronic conditions continue to rise, so too does the need for clear and accurate information on the connections between diet and disease, particularly regarding the cereal grains that dominate the Western diet. In this volume, editors Jodee Johnson and Taylor Wallace assemble a panel of leading experts to address this issue. The result is a comprehensive examination of the cereal and pseudo-cereal grains and their most important bioactive compounds. Not only does this volume offer summaries of existing research, it also places these findings within the larger context of health promotion and disease prevention. This includes frank discussions on the limitations of existing studies, as well as current gaps in research for those who want to offer evidence-based recommendations to their patients. Topics addressed include: Methodical analyses of domesticated grain species, their horticultural history, nutritional composition, and known effects on health Beneficial properties of certain bioactive compounds found in particular grain species How bioactive compounds work within an individual’s overall diet to increase health and prevent disease Academic and industry researchers, as well as medical practitioners and public health professionals, will appreciate Whole Grains and their Bioactives, not only as an engaging overview of current research, but also as an illuminating contribution to the often-murky debate surrounding health and the human diet.

In Origins of Agriculture in Western Central Asia, archaeologist David R. Harris addresses questions of when, how, and why agriculture and settled village life began east of the Caspian Sea. The book describes and assesses evidence from archaeological investigations in Turkmenistan and adjacent parts of Iran, Uzbekistan, and Afghanistan in relation to present and past environmental conditions and genetic and archaeological data on the ancestry of the crops and domestic animals of the Neolithic period. It includes accounts of previous research on the prehistoric archaeology of the region and reports the results of a recent environmental-archaeological project undertaken by British, Russian, and Turkmen archaeologists in Turkmenistan, principally at the early Neolithic site of Jeitun (Djeitun) on the southern edge of the Karakum desert. This project has demonstrated unequivocally that agropastoralists who cultivated barley and wheat, raised goats and sheep, hunted wild animals, made stone tools and pottery, and lived in small mudbrick settlements were present in southern Turkmenistan by 7,000 years ago (c. 6,000 BCE calibrated), where they came into contact with hunter-gatherers of the "Keltiminar Culture." It is possible that barley and goats were domesticated locally, but the available archaeological and genetic evidence leads to the conclusion that all or most of the elements of the Neolithic "Jeitun Culture" spread to the region from farther west by a process of demic or cultural diffusion that broadly parallels the spread of Neolithic agropastoralism from southwest Asia into Europe. By synthesizing for the first time what is currently known about the origins of agriculture in a large part of Central Asia, between the more fully investigated regions of southwest Asia and China, this book makes a unique contribution to the worldwide literature on transitions from hunting and gathering to agriculture.

Ancient Plants and People is a timely discussion of the global perspectives on archaeobotany and the rich harvest of knowledge it yields. Contributors examine the importance of plants to human culture over time and geographic regions and what it teaches of humans, their culture, and their landscapes.
