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.

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.

Genetically Engineered Crops: Experiences and Prospects

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. A tiered process for regulating new crop varieties should focus on a plant's characteristics rather than the process by which it was developed, the committee recommends in its report. New plant varieties that have intended or unintended novel characteristics that may present potential hazards should undergo safety testing -- regardless of whether they were developed using genetic engineering or conventional breeding techniques.

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.

Как он заставит Сьюзан пройти вместе с ним к автомобильной стоянке. Как он поведет машину, если они все же доберутся до. И тут в его памяти зазвучал голос одного из преподавателей Корпуса морской пехоты, подсказавший ему, что делать.

Она будет опять рядом с Дэвидом. Шифровалка начала вибрировать, словно из ее глубин на поверхность рвалось сердитое морское чудовище. Ей слышался голос Дэвида: Беги, Сьюзан, беги. Стратмор приближался к ней, его лицо казалось далеким воспоминанием.

Genetically modified (GM) plants: questions and answers

 Ты это уже. - Вот. Она нахмурилась.

 Ты сказал - в два ночи. Панк кивнул и расхохотался. - Похоже, ты облажался, приятель.

Вам следовало бы привлечь кого-то. - Сьюзан, появление Цифровой крепости влечет за собой очень серьезные последствия для всего будущего нашего агентства. Я не намерен информировать президента за спиной директора.

Почему Стратмор отмел такую возможность. Хейл извивался на полу, стараясь увидеть, чем занята Сьюзан. - Что. Скажи .

Время от времени, когда надо было продлить членство в теннисном клубе или перетянуть старую фирменную ракетку, он подрабатывал переводами для правительственных учреждений в Вашингтоне и его окрестностях. В связи с одной из таких работ он и познакомился со Сьюзан. В то прохладное осеннее утро у него был перерыв в занятиях, и после ежедневной утренней пробежки он вернулся в свою трехкомнатную университетскую квартиру.

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.
