From the 4th – 8th of September 2011, the Eucarpia Fodder Crops and Amenity Grasses Section, held its 29th Meeting in the surroundings of Dublin Castle in Ireland. The theme of the meeting was ‘Breeding strategies for sustainable forage and turf grass improvement’. Grasslands cover a significant proportion of the land mass of the world, and play a pivotal role in global food production. At the same time we are faced with several challenges that affect the way in which we think about this valuable set of resources. The population of the world is expected to exceed 9 billion by 2050, and increase of about one third relative to today’s levels. This population increase will be focused in urban areas, and in what are currently viewed as “developing” countries, meaning that the buying power of this increased population will be greater – shifting the balance of demand from staple crops to high value items such as meat and dairy products. Overall that the world will have to approximately double agricultural output across all categories of food to meet the demands of this larger, urbanised population. This is occurring against a backdrop of equally large challenges in terms of global climate change. Agriculture is already a significant contributor to e.g. greenhouse gas emissions, deforestation and soil erosion. The situation is made more complex by an increased emphasis on biofuels as a solution for our imminent oil shortage, resulting in increased competition between land utilised for food and fuel. In short, agriculture must continue to feed the world, whilst not contributing to damaging it further. It must be sustainable. Plant breeding plays a significant but frequently understated role in meeting the challenges presented by this complex and changing scenario. However, plant breeding and improvement is itself undergoing radical change driven by technology. This book explores how forage and turf breeding is changing and adapting to meet these challenges using the technological advances being experienced in plant breeding as a whole.
Forage and turf are the backbone of sustainable agriculture and contribute extensively to the world economy. The fast-paced advancement of cellular and molecular biology provides novel methods to accelerate or complement conventional breeding efforts. This book contains the most comprehensive reviews on the latest development in applications of molecular techniques for the improvement of forage grasses, forage legumes and turf grasses. Detailed accounts and future opportunities in molecular breeding of forage and turf, from gene discovery to development of improved cultivars, are described in the book. Almost all relevant areas are explored in detail, including tolerance to biotic and abiotic stresses; flowering control; plant-symbiont relations; breeding for animal, human and environmental welfare; molecular markers; transgenics; bioinformatics; population genetics; genomics of the model legume M. truncatula; field testing and risk assessment as well as intellectual property rights. This book will be of interest to researchers in both academia and industry who are involved in forage and turf improvement. It will be especially important to breeders, molecular biologists, geneticists, physiologists and agronomists.
Forages: The Science of Grassland Agriculture, 7th Edition, Volume II will extensively evaluate the current knowledge and information on forage agriculture. Chapters written by leading researchers and authorities in grassland agriculture are aggregated under section themes, each one representing a major topic within grassland science and agriculture. This 7th edition will include two new additional chapters covering all aspects of forage physiology in three separate chapters, instead of one in previous editions. Chapters will be updated throughout to include new information that has developed since the last edition. This new edition of the classic reference serves as a comprehensive supplement to An Introduction to Grassland Agriculture, Volume I.
Forage plant breeding has entered the genome era. This timely book reviews the latest advances in the development and application of molecular technologies which supplement conventional breeding efforts for our major forage crops. It describes the plethora of new technologies and tools now available for high-throughput gene discovery, genome-wide gene expression analysis, production of transgenic plants, genome analysis and marker-assisted selection as applied to forage plants. Detailed accounts are presented of current and future opportunities for innovative applications of these molecular tools and technologies in the identification, functional characterisation, and use of valuable genes in forage production systems and beyond. This book represents a valuable resource for plant breeders, geneticists, and molecular biologists, and will be of particular relevance to advanced undergraduates, postgraduates, and researchers with an interest in forage legumes and grasses.
The cultivation of various turfgrasses has evolved into a dynamic, multi-billion dollar industry. Yet, there is still a real lack of information available for those seeking to understand the complex science behind its growth. This book, edited by two knowledgeable and highly respected experts, presents for the first time a comprehensive study of the various types of turfgrasses, their genetic and biological makeup, and the specifics of when, how, where and why each species was adapted for use. The only book that deals specifically with the science behind the major types of turfgrasses, Turfgrass Biology will prove to be an invaluable, time-saving reference and research tool for professionals interested or engaged in the genesis of turfgrasses.
Agrobacterium tumefaciens is a soil bacterium that for more than a century has been known as a pathogen causing the plant crown gall disease. Unlike many other pathogens, Agrobacterium has the ability to deliver DNA to plant cells and permanently alter the plant genome. The discovery of this unique feature 30 years ago has provided plant scientists with a powerful tool to genetically transform plants for both basic research purposes and for agric- tural development. Compared to physical transformation methods such as particle bomba- ment or electroporation, Agrobacterium-mediated DNA delivery has a number of advantages. One of the features is its propensity to generate single or a low copy number of integrated transgenes with defined ends. Integration of a single transgene copy into the plant genome is less likely to trigger “gene silencing” often associated with multiple gene insertions. When the first edition of Agrobacterium Protocols was published in 1995, only a handful of plants could be routinely transformed using Agrobacterium. Ag- bacterium-mediated transformation is now commonly used to introduce DNA into many plant species, including monocotyledon crop species that were previously considered non-hosts for Agrobacterium. Most remarkable are recent devel- ments indicating that Agrobacterium can also be used to deliver DNA to non-plant species including bacteria, fungi, and even mammalian cells.
