Examples of transgenic soybeans
The genetic makeup of a soybean gives it a wide variety of uses, thus keeping it in high demand. First, manufacturers only wanted to use transgenics to be able to grow more soybeans at a minimal cost to meet this demand, and to fix any problems in the growing process, but they eventually found they could modify the soybean to contain healthier components, or even focus on one aspect of the soybean to produce in larger quantities. These phases became known as the first and second generation of genetically modified (GM) foods. As Peter Celec describes, "benefits of the first generation of GM foods were oriented towards the production process and companies, the second generation of GM foods offers, on contrary, various advantages and added value for the consumer", including "improved nutritional composition or even therapeutic effects."{{cite journal|author=Celec P|display-authors=etal|title=Biological and Biomedical Aspects of Genetically Modified Food|journal=Biomedicine & Pharmacotherapy|volume=59|issue=10|date=Dec 2005|pages=531–40|doi=10.1016/j.biopha.2005.07.013|pmid=16298508}}{{rp|533}}
= Roundup Ready Soybean=
Roundup Ready soybeans (The first variety was also known as GTS 40-3-2 (OECD UI: MON-04032-6)) are a series of genetically engineered varieties of glyphosate-resistant soybeans produced by Monsanto.
Glyphosate kills plants by interfering with the synthesis of the essential amino acids phenylalanine, tyrosine and tryptophan. These amino acids are called "essential" because animals cannot make them; only plants and micro-organisms can make them and animals obtain them by eating plants.{{cite web|publisher=Purdue University, Department of Horticulture and Landscape Architecture|work=Metabolic Plant Physiology Lecture notes|title=Aromatic amino acid biosynthesis, The shikimate pathway – synthesis of chorismate|url=http://www.hort.purdue.edu/rhodcv/hort640c/aromat/ar00007.htm|date=1 October 2009|access-date=2 September 2014|archive-date=19 December 2007|archive-url=https://web.archive.org/web/20071219165155/http://www.hort.purdue.edu/rhodcv/hort640c/aromat/ar00007.htm}}
Plants and microorganisms make these amino acids with an enzyme that only plants and lower organisms have, called 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS).{{cite journal |doi=10.1016/0006-291X(80)90547-1 |title=The herbicide glyphosate is a potent inhibitor of 5-enolpyruvylshikimic acid-3-phosphate synthase |year=1980 |last1=Steinrücken |first1=H.C. |last2=Amrhein |first2=N. |journal=Biochemical and Biophysical Research Communications |volume=94 |issue=4 |pages=1207–12 |pmid=7396959}} EPSPS is not present in animals, which instead obtain aromatic amino acids from their diet.{{cite journal |doi=10.1073/pnas.0603638103 |title=Molecular basis for the herbicide resistance of Roundup Ready crops |year=2006 |last1=Funke |first1=Todd |first2=Huijong |last2=Han |last3=Healy-Fried |first3=Martha L. |last4=Fischer |first4=Markus |last5=Schönbrunn|first5=Ernst |journal=Proceedings of the National Academy of Sciences |volume=103 |issue=35 |jstor=30050705 |bibcode=2006PNAS..10313010F |pmid=16916934 |pages=13010–5 |pmc=1559744|doi-access=free }}
Roundup Ready Soybeans express a version of EPSPS from the CP4 strain of the bacteria Agrobacterium tumefaciens, expression of which is regulated by an enhanced 35S promoter (E35S) from cauliflower mosaic virus (CaMV), a chloroplast transit peptide (CTP4) coding sequence from Petunia hybrida, and a nopaline synthase (nos 3') transcriptional termination element from Agrobacterium tumefaciens.{{cite web|url=http://www.isaaa.org/gmapprovaldatabase/events/default.asp?EventID=94 |title=GM Approval Database |access-date=2011-08-05 |publisher=International Service for the Acquisition of Agri-biotech Applications |archive-url=https://web.archive.org/web/20110930182016/http://www.isaaa.org/gmapprovaldatabase/events/default.asp?EventID=94 |archive-date=2011-09-30 }} The plasmid with EPSPS and the other genetic elements mentioned above was inserted into soybean germplasm with a gene gun by scientists at Monsanto and Asgrow.Homrich MS et al (2012) [http://www.scielo.br/scielo.php?pid=S1415-47572012000600015&script=sci_arttext Soybean genetic transformation: a valuable tool for the functional study of genes and the production of agronomically improved plants] Genet.

=Generic GMO soybeans=
Following expiration of Monsanto's patent on the first variety of glyphosate-resistant Roundup Ready soybeans, development began on glyphosate-resistant generic soybeans. The first variety, developed at the University of Arkansas Division of Agriculture, came to the market in 2015. With a slightly lower yield than newer Monsanto varieties, it costs about 1/2 as much, and seeds can be saved for subsequent years. According to its innovator, it is adapted to conditions in Arkansas. Several other varieties are being bred by crossing the original variety of Roundup Ready soybeans with other soybean varieties.{{cite news|author1=Fred Miller, University of Arkansas Division of Agriculture Communications|title=Arkansas: 'Look Ma, No Tech Fees.'

HB4 soybean, whose technical name is IND-ØØ41Ø-5 soybean, is a variety produced through genetic engineering to respond efficiently to drought conditions.
The HB4 soybean was created to more efficiently tolerate abiotic stress such as drought or hypersaline conditions. These characteristics result in increased yield compared to unmodified varieties.

Soybean has been genetically modified to improve the quality of soy oil. Soy oil has a fatty acid profile that makes it susceptible to oxidation, which makes it rancid, which limits its usefulness in the food industry.{{cite journal | last1 = Clemente | first1 = Tom E. | last2 = Cahoon | first2 = Edgar B. | year = 2009 | title = Soybean Oil: Genetic Approaches for Modification of Functionality and Total Content | journal = Plant Physiology | volume = 151 | issue = 3| pages = 1030–40 | doi=10.1104/pp.109.146282 | pmid=19783644 | pmc=2773065}}{{rp|1030}} Genetic modifications increased the amount of oleic acid and stearic acid and decreased the amount of linolenic acid.{{rp|1031}} By silencing, or knocking out, the delta 9 and delta 12 desaturases.{{rp|1032}}Anthony, 196-7 DuPont Pioneer created a high oleic fatty acid soybean with levels of oleic acid greater than 80%, and started marketing it in 2010.{{rp|1038}}
Regulation
{{main|Regulation of the release of genetic modified organisms}}
The regulation of genetic engineering concerns the approaches taken by governments to assess and manage the risks associated with the development and release of genetically modified crops. There are differences in the regulation of GM crops between countries, with some of the most marked differences occurring between the US and Europe. In the US, the American Soybean Association (ASA) is generally in favor of allowing new GM soy varieties. The ASA especially supports separate regulation of transgenics and all other techniques.{{cite magazine | url=http://soygrowers.com/wp-content/uploads/2019/03/AmericanSoybean_Winter2018_Fnl_WEB.pdf | magazine=American Soybean | date=Winter 2017–2018 | volume=5 | number=3 | publisher=American Soybean Association | pages=1–22 | quote-page=8 | quote=USDA's withdrawal... | title=ASA Responds to Withdrawal of Biotech Rule}} Soy beans are allowed a Maximum Residue Limit of glyphosate of {{convert|20|mg/kg|mg/lb}}{{cite web| url = http://www.fao.org/fao-who-codexalimentarius/standards/pestres/pesticide-detail/en/?p_id=158| archive-url = https://web.archive.org/web/20161019150440/http://www.fao.org/fao-who-codexalimentarius/standards/pestres/pesticide-detail/en/?p_id=158| archive-date = 2016-10-19| title = CODEX Alimentarius: Pesticide Detail}} for international trade.{{Cite web | url=https://www.wto.org/english/thewto_e/coher_e/wto_codex_e.htm | title=WTO | the WTO and the FAO/WHO Codex Alimentarius}} Regulation varies in a given country depending on the intended use of the products of the genetic engineering. For example, a crop not intended for food use is generally not reviewed by authorities responsible for food safety.Wesseler, J. and N. Kalaitzandonakes (2011): Present and Future EU GMO policy.

Controversy
{{Main|Genetically modified food controversies}}
There is a scientific consensus that currently available food derived from GM crops poses no greater risk to human health than conventional food, but that each GM food needs to be tested on a case-by-case basis before introduction. Nonetheless, members of the public are much less likely than scientists to perceive GM foods as safe. The legal and regulatory status of GM foods varies by country, with some nations banning or restricting them, and others permitting them with widely differing degrees of regulation.
A 2010 study found that in the United States, GM crops also provide a number of environmental benefits.{{cite news |author=Andrew Pollack |newspaper=The New York Times |date=April 13, 2010 |url=https://www.nytimes.com/2010/04/14/business/energy-environment/14crop.html?pagewanted=all |title=Study Says Overuse Threatens Gains From Modified Crops}}{{cite book |publisher=National Academies Press | date=2010-07-26 | doi=10.17226/12804 | url=http://www.nap.edu/read/12804/chapter/1 | access-date=2021-04-12 | isbn=978-0-309-14708-8 |title=Impact of Genetically Engineered Crops on Farm Sustainability in the United States }}{{cite web|url=http://www.nationalacademies.org/news/2010/04/genetically-engineered-crops-benefit-many-farmers--but-the-technology-needs-proper-management-to-remain-effective|title=Genetically Engineered Crops Benefit Many Farmers, but the Technology Needs Proper Management to Remain Effective|date=2010-04-13|website=US National Research Council|publisher=US National Academy of Sciences}}
Critics have objected to GM crops on several grounds, including ecological concerns, and economic concerns raised by the fact that these organisms are subject to intellectual property law. GM crops also are involved in controversies over GM food with respect to whether food produced from GM crops are safe and whether GM crops are needed to address the world's food needs. See the genetically modified food controversies article for discussion of issues about GM crops and GM food. These controversies have led to litigation, international trade disputes, and protests, and to restrictive legislation in most countries.Wesseler, J. (ed.) (2005): Environmental Costs and Benefits of Transgenic Crops. Dordrecht, NL: Springer Press

Some medical organizations, including the British Medical Association, advocate further caution based upon the precautionary principle:
{{Cite web|url=http://www.argenbio.org/adc/uploads/pdf/bma.pdf|title=Genetically modified foods and health: a second interim statement|publisher=British Medical Association|date=March 2004|access-date=August 30, 2019|quote=In our view, the potential for GM foods to cause harmful health effects is very small and many of the concerns expressed apply with equal vigour to conventionally derived foods. However, safety concerns cannot, as yet, be dismissed completely on the basis of information currently available.
When seeking to optimise the balance between benefits and risks, it is prudent to err on the side of caution and, above all, learn from accumulating knowledge and experience. Any new technology such as genetic modification must be examined for possible benefits and risks to human health and the environment. As with all novel foods, safety assessments in relation to GM foods must be made on a case-by-case basis.
Members of the GM jury project were briefed on various aspects of genetic modification by a diverse group of acknowledged experts in the relevant subjects. The GM jury reached the conclusion that the sale of GM foods currently available should be halted and the moratorium on commercial growth of GM crops should be continued. These conclusions were based on the precautionary principle and lack of evidence of any benefit. The Jury expressed concern over the impact of GM crops on farming, the environment, food safety and other potential health effects.
The Royal Society review (2002) concluded that the risks to human health associated with the use of specific viral DNA sequences in GM plants are negligible, and while calling for caution in the introduction of potential allergens into food crops, stressed the absence of evidence that commercially available GM foods cause clinical allergic manifestations. The BMA shares the view that there is no robust evidence to prove that GM foods are unsafe but we endorse the call for further research and surveillance to provide convincing evidence of safety and benefit.}}
