Who we are
See the letters and ignwcio note in the April 11, issue of Naturepp. Who we are Ignacio Chapela. Quist, David and Ignacio Chapela 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 hcapela 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?
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. A student of biology and a carpenter for some years. And what does it really help with, for all its beautiful and mysterious construction? A response to a proposed initiative for global conservation.
The day before the workshop I ran a test sample and couldn’t believe the results – some of the native corn tested positive. He has worked on the symbiosis between leafcutter ants and their cultivated fungi.
In sixty-three percent of the cases, they detected genetic contamination. Why can corn from the U.
GRAIN — with David Quist – The Mexican Maize scandal
In order to remove the contamination from the Oaxaca Valley, farmers would not be able to plant maize for at least a year, which would chalela a devastating blow to the local economy.
The food agency maize we tested was highly transgenic – its positive signal was as strong as our transgenic positive.
We just don’t know. Other languages You can read this site in English, Spanish or French by selecting the appropriate language at the top of the page. Born and raised in Gatineau, Canada, Philippe received a Natkre.
There could be various explanations of why this might be, one of which is that the transgenes had become reinserted through recombination. Issues Summary, CEC, www.

Although such critics tried to maintain the guise of scientific objectivity, it’s hard not to see an ideological component in their campaign against Quist and Chapela. What are the implications of your work for farmers in Mexico, and small farmers in particular? In the case of maize, who is asking the questions about the implications for farmers, human health, and global food systems? Monasterio voiced great concern about the future of this spiritual heritage.
In a chappela group Fernando Monasterio, the Mexican government’s safety commissioner for biotechnology, commented on the maize affair and its far-reaching consequences Heaf and Wirzpp. There are some campaigns where it would be undesirable or even disastrous to let the audience know that your organization is directly involved The third major threat to farmers is the loss of markets owing to the pollution of their maize crops.
Maize is the most important crop in Mexico.
Vertical gene flow is the way in which genes are passed on from parent to offspring through cross-pollination. What might we expect the editors to do in this case? Maize is also an extremely important crop to the US, the world’s largest maize producer and exporter. The story began in a small laboratory in Oaxaca in the highlands of Mexico.
This response draws from my work and experience with Latin American conservation reality on the ground. The events that have ugnacio also raise a lot of questions about the true objectivity of ignacii peer-review process in scientific reporting.
Because of its novelty, and because of its potential impact on the economy of plantations, this paper has received a very deep level of scrutiny and challenge. I am concerned about the impact on science. A year and a half on from the publication of your paper in Nature, what is your perspective on why there was such a strong reaction to this paper?
These are the basic questions of ecology: A hallmark of good science is in asking exploratory questions – just as we were doing. A scientist by conviction and aspiring biologist by cbapela. The standard author abbreviation Chapela is used to indicate this person as the author when citing a botanical name. It was a huge PR disaster.
Ignacio CHAPELA | Our Environment at Berkeley
When you look at where the strongest reaction was coming from, there were very significant links to Berkeley and the Berkeley-Novartis deal that was signed five years ago.
This is a clear confirmation of Quist and Chapela’s research. Chapela was initially denied tenure at UC Berkeley indespite a unanimous vote in his favor by an ad hoc tenure committee. In Mexico, those questions have still to be answered.
