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.
This book presents a detailed overview and critical evaluation of the state of the art and latest approaches in genetic manipulation studies on plants to mitigate the impact of climate change on growth and productivity. Each chapter has been written by experts in plant-stress biology and highlights the involvement of a variety of genes/pathways and their regulation in abiotic stress, recent advances in molecular breeding (identification of tightly liked markers, QTLs/genes), transgenesis (introduction of exogenous genes or changing the expression of endogenous stress- responsive genes) and genomics approaches that have made it easier to identify and isolate several key genes involved in abiotic stress such as drought, water lodging/flooding, extreme temperatures, salinity and heavy-metal toxicity. Food and nutritional security has emerged as a major global challenge due to expanding populations, and cultivated areas becoming less productive as a result of extreme climatic changes adversely affecting the quantity and quality of plants. Hence, there is an urgent need to develop crop varieties resilient to abiotic stress to ensure food security and combat increased input costs, low yields and the marginalization of land. The role of GM crops in poverty alleviation, nutrition and health in developing countries and their feasibility in times of climate change are also discussed. Recent advances in gene technologies have shown t he potential for faster, more targeted crop improvements by transferring genes across the sexual barriers. The book is a valuable resource for scientists, researchers, students, planners and industrialists working in the area of biotechnology, plant agriculture, agronomy, horticulture, plant physiology, molecular biology, plant sciences and environmental sciences.
A transgenic organism is a plant, animal, bacterium, or other living organism that has had a foreign gene added to it by means of genetic engineering. Transgenic plants can arise by natural movement of genes between species, by cross-pollination based hybridization between different plant species (which is a common event in flowering plant evolution), or by laboratory manipulations by artificial insertion of genes from another species. Methods used in traditional breeding that generate transgenic plants by non-recombinant methods are widely familiar to professional plant scientists, and serve important roles in securing a sustainable future for agriculture by protecting crops from pest and helping land and water to be used more efficiently.There is worldwide interest in the biosafety issues related to transgenic crops because of issues such as increased pesticide use, increased crop and weed resistance to pesticides, gene flow to related plant species, negative effects on nontarget organisms, and reduced crop and ecosystem diversity. This book is intended to provide the basic information for a wide range of people involved in the release of transgenic crops. These will include scientists and researchers in the initial stage of developing transgenic products, industrialists, and decision makers. It will be of particular interest to plant scientists taking up biotechnological approaches to agricultural improvement for developing nations. - Discusses traditional and future technology for genetic modification - Compares conventional non-GM approaches and genetic modification - Presents a risk assessment methodology for GM techniques - Details mitigation techniques for human and environmental effects
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.
