Discovery of transgenic components in Mexican wild Maize

Lead: U.S scientists said Wednesday that wild corn in remote areas of Mexico has been contaminated with genetically modified corn, a statement that confirms the concerns of some environmentalists Transgenic technology enables grains to resist the effects of pests and the weather through the removal of certain gene fragments or the change of gene structure There has been a heated debate in this field of biotechnology Gnacio chapela and David Quist of the University of California, Berkeley, in the United States, found the genetically modified components in the local corn in the remote area of Sierra Norte de Oaxaca Province, Mexico Their findings were confirmed by Mexican scientists in October and first disclosed in detail in the Journal of natural science "This is a very serious event, because the area where we collect samples is the area where there are a lot of local corn varieties, so we must take measures to protect it immediately "Chapela, assistant professor of Microbiology at the University of Berkeley, said Environmentalists have called for a global moratorium on the development of genetically modified crops, saying the study has increased the focus of other countries on the pollution caused by genetically modified crops "This discovery makes us realize that the biological industry based on nature is a great adventure." "As far as I know, this is the first time that human beings have found genetically modified ingredients in wild plants," said Pete Riley of the earth environmentalists Association He told Reuters.
