caption_attribution_description: English: Soybean field in Hale Township, Hardin County, Ohio, United States, located on the southern side of County Road 200 west of its intersection with Township Road 179. This field consists of multiple soybean test plots (Croplan Genetics); strips of different colors are different varieties of soybeans.
context_page_description: The soybean or soya bean is a species of legume native to East Asia, widely grown for its edible bean, which has numerous uses.
  Traditional unfermented food uses of soybeans include soy milk, from which tofu and tofu skin are made. Fermented soy foods include soy sauce, fermented bean paste, nattō, and tempeh. Fat-free soybean meal is a significant and cheap source of protein for animal feeds and many packaged meals. For example, soybean products, such as textured vegetable protein, are ingredients in many meat and dairy substitutes.
  Soy beans contain significant amounts of phytic acid, dietary minerals and B vitamins. Soy vegetable oil, used in food and industrial applications, is another product of processing the soybean crop. Soybean is the most important protein source for feed farm animals.
context_section_description: Soybeans are one of the "biotech food" crops that have been genetically modified, and genetically modified soybeans are being used in an increasing number of products. In 1995, Monsanto company introduced glyphosate-tolerant soybeans that have been genetically modified to be resistant to Monsanto's glyphosate herbicides through substitution of the Agrobacterium sp. (strain CP4) gene EPSP (5-enolpyruvyl shikimic acid-3-phosphate) synthase. The substituted version is not sensitive to glyphosate.
  In 1997, about 8% of all soybeans cultivated for the commercial market in the United States were genetically modified. In 2010, the figure was 93%. As with other glyphosate-tolerant crops, concern is expressed over damage to biodiversity. A 2003 study concluded the "Roundup Ready" (RR) gene had been bred into so many different soybean cultivars, there had been little decline in genetic diversity, but "diversity was limited among elite lines from some companies".
  The widespread use of such types of GM soybeans in the Americas has caused problems with exports to some regions. GM crops require extensive certification before they can be legally imported into the European Union, where there is considerable supplier and consumer reluctance to use GM products for consumer or animal use. Difficulties with coexistence and subsequent traces of cross-contamination of non-GM stocks have caused shipments to be rejected and have put a premium on non-GM soy.
  A 2006 United States Department of Agriculture report found the adoption of genetically engineered (GE) soy, corn and cotton reduced the amount of pesticides used overall, but did result in a slightly greater amount of herbicides used for soy specifically. The use of GE soy was also associated with greater conservation tillage, indirectly leading to better soil conservation, as well as increased income from off-farming sources due to the greater ease with which the crops can be managed. Though the overall estimated benefits of the adoption of GE soybeans in the United States was $310 million, the majority of this benefit was experienced by the companies selling the seeds (40%), followed by biotechnology firms (28%) and farmers (20%). The patent on glyphosate-tolerant soybeans expired in 2014, so benefits can be expected to shift.
  In 2010, a team of American scientists announced they had sequenced the soybean genome—the first legume to be sequenced.
