Arguments that are based on factual evidence and suggest the negative impact of GM-crops are suppressed in the scientific debate. Soil Biology and Biochemistry With this manuscript we establish several new concepts in the field igbacio coevolutionary biology of fungi. These scientists were naturally interested in publishing their results in Nature FoodFirst Two of the three referees said that they did not challenge the main conclusions of our paper, but suggested writing a correction to part of it.

However, there is no way they could make a statement like that from a scientific, ecological point of view without conducting rigorous science, which I do not think they are not doing, at least at this point.

Who we are

My training is in mycology. A student of biology and a carpenter for some years. A mycologist by training someone who studies fungushe made the discovery about the contamination of maize varieties in Mexico quite by chance. Chapela was co-author with his graduate student, David Quist of a controversial Nature paper about the flow of transgenes into wild Zea mays ssp. It’s evident that the commercial interests of multinational companies are influencing what is supposed to be a scientific discussion.

GRAIN — with David Quist – The Mexican Maize scandal

What is the story behind the study that ignited such controversy around the world? Proceedings of the National Academy of Sciences. After much debate and eight rounds of review, the manuscript was accepted. If Monsanto goes into the highlands of Oaxaca and finds its genes in a farmer’s field, who shoulders the liability — the farmer or the corporation? Maize is also an extremely important crop to the US, the world’s largest maize producer and exporter.

The Laboratory of Microbial Ecology is focused on a relatively small segment of the very large and disparate group of invisible life forms we call “microbes”. We went back to the lab, did some new sampling, and more widespread and stringent analysis, the results of which became the Nature paper.

They are just going to come up with the usual fallback position that absence of evidence is evidence of absence, which is scientifically fallacious.

Ten years on 16 November The global farmland grab by pension funds needs to stop 13 November Supermarkets out of Africa!

Horizontal gene flow is the direct uptake and incorporation of foreign DNA into cells. He even suggested that the mixing could contribute usefully to the diversification of domestic ignnacio quoted in Dreesmann Transgene ecology is a fledgling field. And unfortunately, when a particular branch of science becomes politicised, it becomes a hot ignaio that scares others away from working in the field.

We work with eukaryotic microbes, and we are most focused on those eukaryotic microbes living in terrestrial ecosystems. This smear campaign by The Bivings Group, which works for Monsanto and other biotech companieswas only uncovered by ardent investigative reporting. The consequence has been an exceptional public attention and media coverage for the story. Office hours By Appointment. The postings, which were submitted under the names of private individuals, portrayed Chapela, among other things, as an activist who colludes with environmentalists.

With criticism and pressure coming from many sides, Nature took an unprecedented step: I don’t think it is insignificant that the most vocal detractors of our paper came from the camp that supported the Ignaccio deal back in Other languages You can read this site in English, Spanish or French by selecting the appropriate language at the top of the page.

The GM-corn, originating in the U. Perhaps the greatest advantage of viral marketing is that your message is placed into a context where it is more likely to be considered seriously. From Iowa to Oaxaca: How many of them?

The methods used a combination of traditional soil analysis, stable- and radioactive isotope analysis and DNA-based microbial community characterizationand indeed the concepts behind this manuscript are novel and of very large significance, since plantations of this type are now being planted over extremely large areas globally. This means that in every village in Mexico has these point sources of potential contamination.

This page was last edited on 30 Decemberat So the local production of corn in Mexico is not only threatened by foreign genes, but also by the economic practices of a government that loudly preaches free trade while subsidizing its own industries to undermine local economies in foreign countries.

Here GRAIN talks to Quist about the aftermath of the volcano and the implications for farmers, scientists and consumers. The article went through peer review and the two anonymous reviewers came to opposite conclusions about its content. GRAIN is a small international non-profit organisation that works to support small farmers and social movements in their struggles for community-controlled and biodiversity-based food systems.

Investigating the sixty native varieties “landraces” of cultivated maize in the remote mountains of the Oaxaca Valley of Mexico, they encountered contamination by pollen from genetically modified corn.

Easy passage for the Bt gene Maize is the most important crop in Mexico. Our current attempt to deal with this problem is to develop methods and instrumentation to allow real mapping, at geographical scales, of microbial vhapela, with DNA-sequence specificity.

Do they care about the visibility of things? For organisms like us, who move in the curiously-ordered universe of meter-scale, specific shapes mean much, often the difference between life and death think of our acuteness in detecting minor shape changes in someone’s face ; but for most of life, who operate at time- and space-scales very different to ours?

He has appeared in several films on genetically modified organism and food systems issues, The World According to Monsanto and The Future of Food.

The government submitted its results to Nature, but its paper was rejected in October He is best known for a paper in Nature on the flow of transgenes into wild maize populations, [1] [2] as an outspoken critic of the University of California ‘s ties to the biotechnology industry, as well as a later dispute with the University over denial of tenure that Chapela argued was politically motivated.

Until now an international consensus has held that the areas of origin of domesticated plants must be protected from exposure to GM-crops in order naure preserve this rich genetic heritage for the future.
