The Environmental Effects of Genetically Modified Crops Resistant to Insects
Transgenic crops are currently being cultivated on a commercial scale in many countries. The area devoted to transgenic pest resistant varieties worldwide reached 13 million hectares in 2001. These varieties offer valuable benefits but also pose potential risks. Assessments of their impact on the environment are conducted before they are approved for commercial use, as required by the regulator...
متن کاملAllergenicity Study of Genetically Modified Herbicide Resistant Crops (Bioinformatics Assessment)
Genetically modified herbicide resistant (GMHR) crops have seriously affected the increase of food production. GMHR events are used on >80% 160 million estimated hectares of transgenic crops grown annually across 29 countries. GMHR traits encompass five events, including two transgenes code for glyphosate resistance and insensitive 5enolpyruvylshikimate-3-phosphate synthase (EPSPS), the cp4 eps...
متن کاملWhy genetically modified crops?
This paper is intended to convey the message of the talk I gave at the Theo Murphy meeting at the Kavli Centre in July 2010. It, like the talk, is polemical, and conveys the exasperation felt by a practitioner of genetically modified (GM) plant science at its widespread misrepresentation. I argue that sustainable intensification of agriculture, using GM as well as other technologies, reduces it...
متن کاملMetabolomics of Genetically Modified Crops
Metabolomic-based approaches are increasingly applied to analyse genetically modified organisms (GMOs) making it possible to obtain broader and deeper information on the composition of GMOs compared to that obtained from traditional analytical approaches. The combination in metabolomics of advanced analytical methods and bioinformatics tools provides wide chemical compositional data that contri...
متن کاملThe Anthropology of Genetically Modified Crops
By late in the twentieth century, scientists had succeeded in manipulating organisms at the genetic level, mainly by gene transfer. The major impact of this technology has been seen in the spread of genetically modified (GM) crops, which has occurred with little controversy in some areas and with fierce controversy elsewhere. GM crops raise a very wide range of questions, and I address three ar...
