Genetically modified crops GM crops are plants used in agriculture , the DNA of which has been modified using genetic engineering methods. Plant genomes can be engineered by physical methods or by use of Agrobacterium for the delivery of sequences hosted in T-DNA binary vectors. In most cases, the aim is to introduce a new trait to the plant which does not occur naturally in the species. Examples in food crops include resistance to certain pests, diseases, environmental conditions, reduction of spoilage, resistance to chemical treatments e. Examples in non-food crops include production of pharmaceutical agents , biofuels , and other industrially useful goods, as well as for bioremediation.

Genetically modified crops

The National Academies the collected group of the National Academies of Medicine, Engineering and Sciences are an independent body that provides advice to the government, but does not hold law-making powers. The report was commissioned to examine the evidence behind some of the claims made about GE crops, both those that claim great benefits and those that claim great risks, and it was sponsored by the Burroughs Wellcome Fund, the Gordon and Betty Moore Foundation, the New Venture Fund, and the U. Department of Agriculture, with additional support from the National Academy of Sciences. One of the main conclusions of this page report is that we should refine our conversations and get away from the binary GE or not-GE arguments and instead talk about specific crop varieties, focusing on their traits rather than the process through which they were produced. Evidence for each of these points, drawn from the primary literature and placed into context, is presented in the report. Although long, the report is well organized and it would be good to familiarize yourself with its contents it is free to download You can also download read a four-page PDF report summary , see videos from the public release event, and browse some of the evidence and presentations viewed during the preparation of the report here. Several news organizations and individuals provided useful context and thoughtful opinions about the release of this report, including:.

Genetically Engineered Crops: Experiences and Prospects

The debate about genetically engineered GE crops has become increasingly polarized in the United States, Europe, and some developing countries. The debate polarization has not been resolved in and by the complex and seemingly divergent literature that examines the impacts of the actual and potential adoption and commercialization of GE crops in industrialized and non-industrialized countries. To better understand the rich literature accumulated over the past twenty years, the National Academies of Sciences, Medicine and Engineering NAS established a committee of experts to compile existing questions and issues from the public, collect and assess existing evidence and draw a set of findings, conclusions and recommendations to help the public and policy makers understand better the complex landscape. The NAS Committee objective was to review the accumulated literature to better assess the purported positive and negative impacts of GE crops, as well as the institutional framework in which these technologies have been released. The analysis also included assessing the potential role that emerging genetically engineered technologies will play on future crop improvement efforts and their impact on long term goals such as food security.

An extensive study by the National Academies of Sciences, Engineering, and Medicine has found that new technologies in genetic engineering and conventional breeding are blurring the once clear distinctions between these two crop-improvement approaches. In addition, while recognizing the inherent difficulty of detecting subtle or long-term effects on health or the environment, the study committee found no substantiated evidence of a difference in risks to human health between current commercially available genetically engineered GE crops and conventionally bred crops, nor did it find conclusive cause-and-effect evidence of environmental problems from the GE crops. However, evolved resistance to current GE characteristics in crops is a major agricultural problem.

The National Academies of Sciences, Engineering and Medicine NASEM publishes numerous reports each year that are received with high esteem by the scientific community and public policy makers.
