Book Synopsis Gene Flow Between Crops and Their Wild Relatives by : Meike S. Andersson
Download or read book Gene Flow Between Crops and Their Wild Relatives written by Meike S. Andersson and published by JHU Press. This book was released on 2010-02 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reviewing the relevant scientific and technical literature, this work summarizes the current state-of-the-art knowledge related to gene flow and introgression (the permanent incorporation of genetic information from one set of differentiated populations into another) between genetically modified crops and their wild relatives. They analyze the biological framework for protecting the genetic integrity of indigenous wild relatives of crops in centers of crop origin and diversity, focusing on the issues of emission, dispersal, and deposition of pollen and/or seed; the likelihood and extent of gene flow from crops to wild relatives; and stabilization and the spread of traits in wild species. The material is organized into crop chapters, each of which covers general biological information of the crop; the most important crop wild relatives together with information about their ploidy levels, diverse genomes, centers of origin, and geographic distribution; the crop's potential for hybridization with its wild relatives; pollen flow studies related to pollen dispersal distances and hybridization rates; the current state of the genetic modification technology regarding that crop; and research gaps. The crop chapters discuss banana and plantain; barley; canola and oilseed rape; cassava, manioc, and yucca; chickpea; common bean; cotton; cowpea; finger millet; maize and corn; oat; peanut and groundnut; pearl millet; pigeonpea; potato; rice; sorghum; soybean; sweet potato, batata, and camote; and wheat and bread wheat.
Book Synopsis Dangerous Liaisons? by : Norman C. Ellstrand
Download or read book Dangerous Liaisons? written by Norman C. Ellstrand and published by JHU Press. This book was released on 2005-04-13 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the advent of genetic engineering, "designer" crops might interbreed with natural populations. Could such romances lead to the evolution of "superweeds", as some have suggested? But haven't crops had sex with wild plants in the past? Has such gene swapping occurred without consequences? And if consequences have indeed occurred, what lessons can be gleaned for engineered crops? In Dangerous Liaisons? Norman Ellstrand examines these and other questions. He begins with basic information about the natural hybridization process. He then describes what we now know about hybridization between the world's most important crops—such as wheat, rice, maize, and soybeans—and their wild relatives. Such hybridization, Ellstrand explains, is not rare, and has occasionally had a substantial impact. In some cases, the result was problematic weeds. In others, crop genes have diluted natural diversity to the point that wild populations of certain rare species were absorbed into the gene pool of the more common crop, essentially bringing the wild species to the brink of extinction. Ellstrand concludes with a look to the future. Will engineered crops pose a greater threat than traditional crops? If so, can gene flow and hybridization be managed to control the escape of engineered genes? This book will appeal to academics, policy makers, students, and all with an interest in environmental issues.
Book Synopsis Introgression from Genetically Modified Plants Into Wild Relatives by : Hans C. M. den Nijs
Download or read book Introgression from Genetically Modified Plants Into Wild Relatives written by Hans C. M. den Nijs and published by CABI. This book was released on 2004-01-01 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 ).

The editor has brought together a diverse group of professionals, representing the several distinct areas impacted by the new technology of herbicide-resistant crops. The wide range of viewpoints presented in this book creates a balanced and complete survey, providing a notable contribution to the literature.
Book Synopsis Safety of Genetically Engineered Foods by : National Research Council
Download or read book Safety of Genetically Engineered Foods written by National Research Council and published by National Academies Press. This book was released on 2004-07-08 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Assists policymakers in evaluating the appropriate scientific methods for detecting unintended changes in food and assessing the potential for adverse health effects from genetically modified products. In this book, the committee recommended that greater scrutiny should be given to foods containing new compounds or unusual amounts of naturally occurring substances, regardless of the method used to create them. The book offers a framework to guide federal agencies in selecting the route of safety assessment. It identifies and recommends several pre- and post-market approaches to guide the assessment of unintended compositional changes that could result from genetically modified foods and research avenues to fill the knowledge gaps.
Book Synopsis Genetic and Ecological Consequences of Transgene Flow to the Wild Flora by :
Download or read book Genetic and Ecological Consequences of Transgene Flow to the Wild Flora written by and published by . This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Gene flow from crops to wild relatives by sexual reproduction is one of the major issues in risk assessment for the cultivation of genetically engineered (GE) plants. The main factors which influence hybridization and introgression, the two processes of gene flow, as well as the accompanying containment measures of the transgene, are reviewed. The comparison of risks between Switzerland and Europe highlights the importance of regional studies. Differences were assessed for barley, beet and wheat. Moreover, transgene flow through several wild species acting as bridge (bridge species) has been up to now poorly investigated. Indeed, transgene flow may go beyond the closest wild relative, as in nature several wild species complexes hybridize. Its importance is assessed by several examples in Poaceae. Finally, the transgene itself has genetic and ecological consequences that are reviewed. Transgenic hybrids between crops and wild relatives may have lower fitness than the wild relatives, but in several cases, no cost was detected. On the other hand, the transgene provides advantages to the hybrids, in the case of selective value as a Bt transgene in the presence of herbivores. Genetic and ecological consequences of a transgene in a wild species are complex and depend on the type of transgene, its insertion site, the density of plants and ecological factors. More studies are needed for understanding the short and long term consequences of escape of a transgene in the wild.
Book Synopsis Distant Hybridization of Crop Plants by : G. Kalloo
Download or read book Distant Hybridization of Crop Plants written by G. Kalloo and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wild taxa are invaluable sources of resistance to diseases, insects/ pests, nematodes, temperature extremes, salinity and alkalinity stresses, and also of nutritional quality; adaptation; genetic diversity and new species. Utilization of wild relatives of a crop depends largely upon its crossability relations with cultivated varieties. Sev eral wild species are not crossable with the commercial cultivars due to various isolation barriers. Furthermore, in a few cases, hybridiza tion is possible only in one direction and reciprocal crosses are not successful, thus depriving the utilization of desired cytoplasm of many species. However, techniques have been developed to over come many barriers and hybrid plants are produced. New crop species have been developed by overcoming the F 1 sterility and producing amphidiploids and such crops are commercially being grown in the field. The segregation pattern ofF 1 hybrids produced by distant hybridization in segregating generations are different from the intervarietal hybrids. In former cases, generally, unidirectional segregation takes place in early generations and accordingly, selec tion procedures are adopted. In most of the cases, backcross or modified backcross methods have been followed to utilize wild species, and thus numerous types of resistance and other economical attributes have been transferred in the recurrent parents. Protoplast fusion has been amply demonstrated in a number of cases where sexual hybridization was not possible and, as a result, hybrids have been produced.
Book Synopsis Hybrid Zones and the Evolutionary Process by : Richard Gerald Harrison
Download or read book Hybrid Zones and the Evolutionary Process written by Richard Gerald Harrison and published by Oxford University Press, USA. This book was released on 1993 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hybrid zones--geographical areas in which the hybrids of two races are found--have attracted the attention of evolutionary biologists for many years, both because they are windows on the evolutionary process and because the patterns of animals and plant variation seen in hybrid zones do notfit the traditional classification schemes of taxonomists. Hybrid zones provide insights into the nature of the species, the way barriers to gene exchange function, the genetic basis of those barriers, the dynamics of the speciation process. Hybrid Zones and the Evolutionary Process synthesizes theextensive research literature in this field and points to new directions in research. It will be read with interest by evolutionary biologists, geneticists, and biogeographers.

Book Synopsis Genetically Modified Planet by : C. Neal Stewart Jr.
Download or read book Genetically Modified Planet written by C. Neal Stewart Jr. and published by Oxford University Press. This book was released on 2004-08-19 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetically modified plants are currently causing controversy worldwide; a great deal has been written about their supposed environmental effects. However, the newspaper headlines and public debates often provide a level of reasoning akin to "this is your brain on genetically modified corn," which is to say, they exclude or exaggerate the actual scientific research on the impacts of these plants. Genetically Modified Planet goes beyond the rhetoric to investigate for concerned consumers the actual state of scientific research on genetically modified plants. Stewart argues that while there are indeed real and potential risks of growing engineered crops, there are also real and overwhelmingly positive environmental benefits.
Book Synopsis Gene Flow from GM Plants by : Guy M. Poppy
Download or read book Gene Flow from GM Plants written by Guy M. Poppy and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gene flow is not unique to genetically modified (GM) crops, but the possibility of the spread of transgenic DNA to wild and domesticated relatives raises a new set of issues for scientists and policymakers to consider. Unfortunately, we are still too often unable to quantify the risks of ecological damage associated with gene flow. This is due partly to the huge breadth of knowledge required to assemble a comprehensive risk assessment. For example, many scientists active in research on the mechanics of gene flow nevertheless lack a deep understanding of what is required to identify, characterise and assess ecological risk, and many of those who are aware of the risk assessment process and the framework used for legislation have insufficient knowledge of the reproductive biology, agricultural systems, modelling and ecological literature required to compile a balanced risk assessment. This book, set in the context of gene flow in general, considers the assessment, measurement and management of the risks of gene flow from GM plants, combining the expertise of all the various stakeholders. It is directed at researchers and professionals in plant molecular genetics and plant ecology, in both the academic and industrial sectors.
Book Synopsis Innovation, Economic Development, and Intellectual Property in India and China by : Kung-Chung Liu
Download or read book Innovation, Economic Development, and Intellectual Property in India and China written by Kung-Chung Liu and published by Springer Nature. This book was released on 2019-09-06 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book analyses intellectual property codification and innovation governance in the development of six key industries in India and China. These industries are reflective of the innovation and economic development of the two economies, or of vital importance to them: the IT Industry; the film industry; the pharmaceutical industry; plant varieties and food security; the automobile industry; and peer production and the sharing economy. The analysis extends beyond the domain of IP law, and includes economics and policy analysis. The overarching concern that cuts through all chapters is an inquiry into why certain industries have developed in one country and not in the other, including: the role that state innovation policy and/or IP policy played in such development; the nature of the state innovation policy/IP policy; and whether such policy has been causal, facilitating, crippling, co-relational, or simply irrelevant. The book asks what India and China can learn from each other, and whether there is any possibility of synergy. The book provides a real-life understanding of how IP laws interact with innovation and economic development in the six selected economic sectors in China and India. The reader can also draw lessons from the success or failure of these sectors.

Book Synopsis Genetically Engineered Crops by : National Academies of Sciences, Engineering, and Medicine
Download or read book Genetically Engineered Crops written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-01-28 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.
