GM crops have been the source of international trade disputes and tensions within food-exporting nations over whether introduction of genetically modified crops would endanger exports to other countries. [434] In Canada in 2010, flax exports to Europe were rejected when traces of an experimental GM flax were found in shipments. [435]
Genetically modified crops (GM crops) are genetically modified plants that are used in agriculture. The first crops developed were used for animal or human food and provide resistance to certain pests, diseases, environmental conditions, spoilage or chemical treatments (e.g. resistance to a herbicide).
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 .
The majority of GM crops have been modified to be resistant to selected herbicides, usually a glyphosate or glufosinate based one. Genetically modified crops engineered to resist herbicides are now more available than conventionally bred resistant varieties; [20] in the USA 93% of soybeans and most of the GM maize grown is glyphosate tolerant. [21]
The corporate push for genetically modified food arouses great suspicion. Critics charge that GM food ("Frankenfood") is profitable to industry not only because it can be patented but because crop uniformity will eventually drive up pesticide demand. The charge that big food interests take advantage of poverty to open new markets for GM food is ...
Pollen barriers consisting of conventional crops of the same species as the GM crop have a special advantage, as the conventional plants not only physically limit the GM pollen flow, but also produce competitive, conventional pollen. During harvest, the buffer strip of conventional crops is considered part of the GM crop yield. [4]
Genetically modified maize is a genetically modified crop. Specific maize strains have been genetically engineered to express agriculturally-desirable traits, including resistance to pests and to herbicides. Maize strains with both traits are now in use in multiple countries.
The farm contained a trial crop of genetically modified (GM) maize owned by agrochemical company AgrEvo (later Aventis, now Plant Genetic Systems) and commissioned by the Institute of Terrestrial Ecology (ITE). While the protest was part of a larger movement by Greenpeace against GM crops, the leadership of Melchett and the number of arrests ...
