This volume offers an up-to-date overview of biotechnologically oriented barley research. It is structured into two major sections: the first focusing on current agricultural challenges and approaches to barley improvement, and the second providing insights into recent advances in methodology. Leading scientists highlight topics such as: the global importance of barley; genetic diversity and genebanks; domestication; shoot and inflorescence architecture; reproductive development; mineral nutrition; photosynthesis and leaf senescence; grain development; drought tolerance; viral and fungal pathogens; phytophagous arthropods; molecular farming; sequence resources; induced genetic variation and TILLING; meiotic recombination; Hordeum bulbosum; genome-wide association scans; genomic selection; haploid technology; genetic engineering; and whole plant phenomics. Providing comprehensive information on topics ranging from fundamental aspects to specific applications, this book offers a useful resource for scientists, plant breeders, teachers and advanced students in the fields of molecular and plant cell biology, plant biotechnology, and agronomy.
This book presents an overview of the state-of-the-art in barley genome analysis, covering all aspects of sequencing the genome and translating this important information into new knowledge in basic and applied crop plant biology and new tools for research and crop improvement. Unlimited access to a high-quality reference sequence is removing one of the major constraints in basic and applied research. This book summarizes the advanced knowledge of the composition of the barley genome, its genes and the much larger non-coding part of the genome, and how this information facilitates studying the specific characteristics of barley. One of the oldest domesticated crops, barley is the small grain cereal species that is best adapted to the highest altitudes and latitudes, and it exhibits the greatest tolerance to most abiotic stresses. With comprehensive access to the genome sequence, barley’s importance as a genetic model in comparative studies on crop species like wheat, rye, oats and even rice is likely to increase.
Conceived with the aim of sorting fact from fiction over genetically modified (GM) crops, this book brings together the knowledge of 30 specialists in the field of transgenic plants. It covers the generation and detection of these plants as well as the genetic traits conferred on transgenic plants. In addition, the book looks at a wide variety of crops, ornamental plants and tree species that are subject to genetic modifications, assessing the risks involved in genetic modification as well as the potential economic benefits of the technology in specific cases. The book’s structure, with fully cross-referenced chapters, gives readers a quick access to specific topics, whether that is comprehensive data on particular species of ornamentals, or coverage of the socioeconomic implications of GM technology. With an increasing demand for bioenergy, and the necessary higher yields relying on wider genetic variation, this book supplies all the technical details required to move forward to a new era in agriculture.
Barley has been cultivated for more than 10,000 years. Barley improvement studies always have the privilege of the breeders and scientists. This review is expected to provide a resource for researchers interested in barley improvement research in terms of mutation breeding, tissue culture, gene transfers, gene editing, molecular markers, transposons, epigenetic, genomic studies and system biology. We aimed to discuss some important and/or recent studies and improvements about barley for understanding the factors responsible for converting barley plants into the superior cereals, which occurred through gene transfers, gene editing and molecular breeding, which is important and could help us enhance the current pool of cultivated barley species to provide enough material for the future.
Reviews the current knowledge of many diverse aspects of barley research, through a mixture of detailed review articles and shorter accounts of specific topics in which noteworthy advances are being made. The volume is divided into six main sections covering: phylogeny and wild relatives, basic genetics, molecular analysis of metabolism and development, seed structure and composition, pathogen resistance, and genetic engineering and biotechnology.

Plants are subjected to a variety of abiotic stresses such as drought, temperature, salinity, air pollution, heavy metals, UV radiations, etc. To survive under these harsh conditions plants are equipped with different resistance mechanisms which vary from species to species. Due to the environmental fluctuations agricultural and horticultural crops are often exposed to different environmental stresses leading to decreased yield and problems in the growth and development of the crops. Drought stress has been found to decrease the yield to an alarming rate of some important crops throughout the globe. During last few decades, lots of physiological and molecular works have been conducted under water stress in crop plants. Water Stress and Crop Plants: A Sustainable Approach presents an up-to-date in-depth coverage of drought and flooding stress in plants, including the types, causes and consequences on plant growth and development. It discusses the physiobiochemical, molecular and omic approaches, and responses of crop plants towards water stress. Topics include nutritional stress, oxidative stress, hormonal regulation, transgenic approaches, mitigation of water stress, approaches to sustainability, and modern tools and techniques to alleviate the water stress on crop yields. This practical book offers pragmatic guidance for scientists and researchers in plant biology, and agribusinesses and biotechnology companies dealing with agronomy and environment, to mitigate the negative effects of stress and improve yield under stress. The broad coverage also makes this a valuable guide enabling students to understand the physiological, biochemical, and molecular mechanisms of environmental stress in plants.
With contributions from nearly 130 internationally renowned experts in the field, this reference details advances in transgenic plant construction and explores the social, political, and legal aspects of genetic plant manipulation. It provides analyzes of the history, genetics, physiology, and cultivation of over 30 species of transgenic seeds, fruits, and vegetables. Stressing the impact of genetic engineering strategies on the nutritional and functional benefit of foods as well as on consumer health and the global market economy, the book covers methods of gene marking, transferring, and tagging public perceptions to the selective breeding, hybridization, and recombinant DNA manipulation of food.

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.
