A Hard Look at 3 Myths aboutGenetically Modified CropsSuperweeds Suicides Stealthy genes The true the false and the still unknown about

transgenic crops

May 1 2013 | By Natasha Gilbert and Nature magazine

In the pitched debate over genetically

hard to see where scientific evidence ends

and dogma and speculation begin In the

nearly 20 years since they were first

commercialized GM crop technologies have

seen dramatic uptake Advocates say that

they have increased agricultural production

pesticides from being sprayed But critics

question their environmental social and

Researchers farmers activists and GM seed

companies all stridently promote their

views but the scientific data are often inconclusive or contradictory Complicated

truths have long been obscured by the fierce rhetoric ldquoI find it frustrating that the

debate has not moved onrdquo says Dominic Glover an agricultural socioeconomist at

Wageningen University and Research Center in the Netherlands ldquoThe two sides speak

different languages and have different opinions on what evidence and issues matterrdquo

he says

Here Nature takes a look at three pressing questions are GM crops fuelling the rise of

the herbicide glyphosate which is marketed as Roundup by Monsanto in St Louis

Missouri The herbicidendashcrop combination worked spectacularly well mdash until it didnrsquot

In 2004 herbicide-resistant amaranth was found in one county in Georgia by 2011 it

had spread to 76 ldquoIt got to the point where some farmers were losing half their cotton

fields to the weedrdquo says Holder

Some scientists and anti-GM groups warned that GM crops by encouraging liberal

use of glyphosate were spurring the evolution of herbicide resistance in many weeds

Twenty-four glyphosate-resistant weed species have been identified since Roundup-

tolerant crops were introduced in 1996 But herbicide resistance is a problem for

farmers regardless of whether they plant GM crops Some 64 weed species are

resistant to the herbicide atrazine for example and no crops have been genetically

modified to withstand it (see lsquoThe rise of superweedsrsquo)

Still glyphosate-tolerant plants could be considered victims of their own success

Farmers had historically used multiple herbicides which slowed the development of

resistance They also controlled weeds through ploughing and tilling mdash practices that

deplete topsoil and release carbon dioxide but do not encourage resistance The GM

crops allowed growers to rely almost entirely on glyphosate which is less toxic than

many other chemicals and kills a broad range of weeds without ploughing Farmers

planted them year after year without rotating crop types or varying chemicals to deter

resistance

This strategy was supported by claims

from Monsanto that glyphosate resistance

was unlikely to develop naturally in weeds

when the herbicide was used properly As

late as 2004 the company was publicizing

a multi-year study suggesting that

rotating crops and chemicals does not

help to avert resistance When applied at

Monsantorsquos recommended doses

glyphosate killed weeds effectively and

ldquowe know that dead weeds will not

become resistantrdquo said Rick Cole now

Monsantorsquos technical lead of weed

management in a trade-journal advertisement at the time The study published in

2007 was criticized by scientists for using plots so small that the chances of resistance

developing were very low no matter what the practice

Glyphosate-resistant weeds have now been found in 18 countries worldwide with

significant impacts in Brazil Australia Argentina and Paraguay says Ian Heap

director of the International Survey of Herbicide Resistant Weeds based in Corvallis

Oregon And Monsanto has changed its stance on glyphosate use now recommending

that farmers use a mix of chemical products and ploughing But the company stops

short of acknowledging a role in creating the problem ldquoOver-confidence in the system

combined with economic drivers led to reduced diversity in herbicide userdquo Cole tells

155 million kilograms of herbicide between 1996 and 2011 a 61 reduction from

what would have been used on conventional cotton And GM crop technology

delivered an 89 improvement to the environmental impact quotient mdash a measure

that considers factors such as pesticide toxicity to wildlife mdash says Graham Brookes co-

director of PG Economics and a co-author of the industry-funded study which many

scientists consider to be among the fieldrsquos most extensive and authoritative

assessments of environmental impacts

The question is how much longer those benefits will last So far farmers have dealt

with the proliferation of resistant weeds by using more glyphosate supplementing it

with other herbicides and ploughing A study by David Mortensen a plant ecologist at

Pennsylvania State University in University Park predicts that total herbicide use in

the United States will rise from around 15 kilograms per hectare in 2013 to more than

35 kilograms per hectare in 2025 as a direct result of GM crop use

To offer farmers new weed-control strategies Monsanto and other biotechnology

companies such as Dow AgroSciences based in Indianapolis Indiana are developing

new herbicide-resistant crops that work with different chemicals which they expect to

commercialize within a few years

Mortensen says that the new technologies will lose their effectiveness as well But

abandoning chemical herbicides completely is not a viable solution says Jonathan

Gressel a weed scientist at the Weizmann Institute of Science in Rehovot Israel

Using chemicals to control weeds is still more efficient than ploughing and tilling the

soil and is less environmentally damaging ldquoWhen farmers start to use more

sustainable farming practices together with mixtures of herbicides they will have

fewer problemsrdquo he says

GM cotton has driven farmers to suicide False

During an interview in March Vandana Shiva an environmental and feminist activist

from India repeated an alarming statistic ldquo270000 Indian farmers have committedsuicide since Monsanto entered the Indian seed marketrdquo she said ldquoItrsquos a genociderdquo

The claim based on an increase in total suicide rates across the country in the late

1990s has become an oft-repeated story of corporate exploitation since Monsanto

began selling GM seed in India in 2002

Bt cotton which contains a gene from the

bacterium Bacillus thuringiensis to ward

off certain insects had a rough start

Seeds initially cost five times more than

local hybrid varieties spurring localtraders to sell packets containing a mix of

Bt and conventional cotton at lower

prices The sham seeds and

misinformation about how to use the

product resulted in crop and financial

losses This no doubt added strain to rural

farmers who had long been under the

pressures of a tight credit system that

forced them to borrow from local lenders

But says Glover ldquoit is nonsense to attribute farmer suicides solely to Bt cottonrdquo

Although financial hardship is a driving factor in suicide among Indian farmers there

has been essentially no change in the suicide rate for farmers since the introduction of

Bt cotton

That was shown by researchers at the International Food Policy Research Institute in

Washington DC who scoured government data academic articles and media reports

about Bt cotton and suicide in India Their findings published in 2008 and updated in

2011 show that the total number of suicides per year in the Indian population rose

from just under 100000 in 1997 to more than 120000 in 2007 But the number of

suicides among farmers hovered at around 20000 per year over the same period

And since its rocky beginnings Bt cotton has benefited farmers says Matin Qaim an

agricultural economist at Georg August University in Goumlttingen Germany who has

been studying the social and financial impacts of Bt cotton in India for the past 10

years In a study of 533 cotton-farming households in central and southern India

Qaim found that yields grew by 24 per acre between 2002 and 2008 owing to

reduced losses from pest attacks Farmersrsquo profits rose by an average of 50 over the

same period owing mainly to yield gains (see lsquo A steady rate of tragedy rsquo) Given the

profits Qaim says it is not surprising that more than 90 of the cotton now grown in

India is transgenic

Glenn Stone an environmental anthropologist at Washington University in St Louis

says that the empirical evidence for yield increases with Bt cotton is lacking He has

conducted original field studies and analyzed the research literature on Bt cotton

yields in India and says that most peer-reviewed studies reporting yield increases

with Bt cotton have focused on short time periods often in the early years after the

technology came online This he says introduced biases farmers who adopted the

technology first tended to be wealthier and more educated and their farms were

already producing higher-than-average yields of conventional cotton They achieved

high yields of Bt cotton partly because they lavished the expensive GM seeds with care

and attention The problem now is that there are hardly any conventional cotton farms

left in India to compare GM yields and profits against says Stone Qaim agrees that

many studies showing financial gains focus on short-term impacts but his study

published in 2012 controlled for these biases and still found continued benefits

Bt cotton did not cause suicide rates to spike says Glover but neither is it the sole

reason for the yield improvements ldquoBlanket conclusions that the technology is a

success or failure lack the right level of nuancerdquo he says ldquoItrsquos an evolving story in

India and we have not yet reached a definitive conclusionrdquo

Transgenes spread to wild crops in Mexico UnknownIn 2000 some rural farmers in the mountains of Oaxaca Mexico wanted to gain

organic certification for the maize (corn) they grew and sold in the hope of generating

extra income David Quist then a microbial ecologist at the University of California

Berkeley agreed to help in exchange for access to their lands for a research project

But Quistrsquos genetic analyses uncovered a surprise the locally produced maize

contained a segment of the DNA used to spur expression of transgenes in Monsantorsquos

glyphosate-tolerant and insect-resistant maize

GM crops are not approved for commercial production in Mexico So the transgenes

probably came from GM crops imported from the United States for consumption and

planted by local farmers who probably didnrsquot know that the seeds were transgenic

Quist speculated at the time that the local maize probably cross-bred with these GM

varieties thereby picking up the transgenic DNA

When the discovery was published in Nature a media and political circus descended

on Oaxaca Many vilified Monsanto for contaminating maize at its historic origin mdash a

place where the crop was considered sacred And Quistrsquos study came under fire for

technical deficiencies including problems with the methods used to detect the

transgenes and the authorsrsquo conclusion that transgenes can fragment and scatter

throughout the genome Nature eventually withdrew support for the paper but

stopped short of retracting it ldquoThe evidence available is not sufficient to justify the

publication of the original paperrdquo read an editorial footnote to a critique of the

research published in 2002

Since then few rigorous studies of transgene flow into Mexican maize have been

published owing mainly to a dearth of research funding and they show mixed results

In 2003ndash04 Allison Snow a plant ecologist at Ohio State University in Columbus

sampled 870 plants taken from 125 fields in Oaxaca and found no transgenic

sequences in maize seeds

But in 2009 a study led by Elena Alvarez-Buylla a molecular ecologist at the National

Autonomous University of Mexico in Mexico City and Alma Pintildeeyro-Nelson a plant

molecular geneticist now at the University of California Berkeley found the same

transgenes as Quist in three samples taken from 23 sites in Oaxaca in 2001 and in two

samples taken from those sites in 2004 In another study Alvarez-Buylla and her co-

authors found evidence of transgenes in a small percentage of seeds from 1765

households across Mexico Other studies conducted within local communities have

found transgenes more consistently but few have been published

Snow and Alvarez-Buylla agree that differences in sampling methods can lead to

discrepancies in transgene detection ldquoWe sampled different fieldsrdquo says Snow ldquoThey found them but we didnrsquotrdquo

The scientific community remains split on whether transgenes have infiltrated maize

populations in Mexico even as the country grapples with whether to approve

commercialization of Bt maize

ldquoIt seems inevitable that there will be a movement of transgenes into local maize

cropsrdquo says Snow ldquoThere is some proof that it is happening but it is very difficult to

say how common it is or what are the consequencesrdquo Alvarez-Buylla argues that the

spread of transgenes will harm the health of Mexican maize and change

characteristics such as a varietyrsquos look and taste that are important to rural farmersOnce the transgenes are present it will be very difficult if not impossible to get rid of

them she says Critics speculate that GM traits that accumulate in the genomes of

local maize populations over time could eventually affect plant fitness by using up

energy and resources or by disrupting metabolic processes for example

Snow says that there is no evidence so far for negative effects And she expects that if

the transgenes now in use drift to other plants they will have neutral or beneficial

effects on plant growth In 2003 Snow and her colleagues showed that when Bt

sunflowers ( Helianthus annuus) were bred with their wild counterparts transgenic

offspring still required the same kind of close care as its cultivated parent but were

less vulnerable to insects and produced more seeds than non-transgenic plants Few

similar studies have been conducted says Snow because the companies that own the

rights to the technology are generally unwilling to let academic researchers perform

the experiments

In Mexico the story goes beyond potential environmental impacts Kevin Pixley a

crop scientist and the director of the genetic resources program at the International

Maize and Wheat Improvement Center in El Batan Mexico says that scientists

arguing on behalf of GM technologies in the country have missed a crucial point

ldquoMost of the scientific community doesnrsquot understand the depth of the emotional and

cultural affiliation maize has for the Mexican populationrdquo he says

is nuanced equivocal and undeniably messy Transgenic crops will not solve all the

Just a minor side note but Im sure there are other genetic differences between the Mexican Maize

and corn planted in the US and elsewhere If these introduced gene sequences can migrate into

Mexican maize even though the planting of GM corn is banned then how much more must the

genes of non-GM but non-native Maize have migrated into the Mexican maize

155 million kilograms of herbicide between 1996 and 2011 a 61 reduction from

what would have been used on conventional cotton And GM crop technology

delivered an 89 improvement to the environmental impact quotient mdash a measure

that considers factors such as pesticide toxicity to wildlife mdash says Graham Brookes co-

director of PG Economics and a co-author of the industry-funded study which many

scientists consider to be among the fieldrsquos most extensive and authoritative

assessments of environmental impacts

The question is how much longer those benefits will last So far farmers have dealt

with the proliferation of resistant weeds by using more glyphosate supplementing it

with other herbicides and ploughing A study by David Mortensen a plant ecologist at

Pennsylvania State University in University Park predicts that total herbicide use in

the United States will rise from around 15 kilograms per hectare in 2013 to more than

35 kilograms per hectare in 2025 as a direct result of GM crop use

To offer farmers new weed-control strategies Monsanto and other biotechnology

companies such as Dow AgroSciences based in Indianapolis Indiana are developing

new herbicide-resistant crops that work with different chemicals which they expect to

commercialize within a few years

Mortensen says that the new technologies will lose their effectiveness as well But

abandoning chemical herbicides completely is not a viable solution says Jonathan

Gressel a weed scientist at the Weizmann Institute of Science in Rehovot Israel

Using chemicals to control weeds is still more efficient than ploughing and tilling the

soil and is less environmentally damaging ldquoWhen farmers start to use more

sustainable farming practices together with mixtures of herbicides they will have

fewer problemsrdquo he says

GM cotton has driven farmers to suicide False

During an interview in March Vandana Shiva an environmental and feminist activist

from India repeated an alarming statistic ldquo270000 Indian farmers have committedsuicide since Monsanto entered the Indian seed marketrdquo she said ldquoItrsquos a genociderdquo

The claim based on an increase in total suicide rates across the country in the late

1990s has become an oft-repeated story of corporate exploitation since Monsanto

began selling GM seed in India in 2002

Bt cotton which contains a gene from the

bacterium Bacillus thuringiensis to ward

off certain insects had a rough start

Seeds initially cost five times more than

local hybrid varieties spurring localtraders to sell packets containing a mix of

Bt and conventional cotton at lower

prices The sham seeds and

misinformation about how to use the

product resulted in crop and financial

losses This no doubt added strain to rural

farmers who had long been under the

pressures of a tight credit system that

forced them to borrow from local lenders

But says Glover ldquoit is nonsense to attribute farmer suicides solely to Bt cottonrdquo

Although financial hardship is a driving factor in suicide among Indian farmers there

has been essentially no change in the suicide rate for farmers since the introduction of

Bt cotton

That was shown by researchers at the International Food Policy Research Institute in

Washington DC who scoured government data academic articles and media reports

about Bt cotton and suicide in India Their findings published in 2008 and updated in

2011 show that the total number of suicides per year in the Indian population rose

from just under 100000 in 1997 to more than 120000 in 2007 But the number of

suicides among farmers hovered at around 20000 per year over the same period

And since its rocky beginnings Bt cotton has benefited farmers says Matin Qaim an

agricultural economist at Georg August University in Goumlttingen Germany who has

been studying the social and financial impacts of Bt cotton in India for the past 10

years In a study of 533 cotton-farming households in central and southern India

Qaim found that yields grew by 24 per acre between 2002 and 2008 owing to

reduced losses from pest attacks Farmersrsquo profits rose by an average of 50 over the

same period owing mainly to yield gains (see lsquo A steady rate of tragedy rsquo) Given the

profits Qaim says it is not surprising that more than 90 of the cotton now grown in

India is transgenic

Glenn Stone an environmental anthropologist at Washington University in St Louis

says that the empirical evidence for yield increases with Bt cotton is lacking He has

conducted original field studies and analyzed the research literature on Bt cotton

yields in India and says that most peer-reviewed studies reporting yield increases

with Bt cotton have focused on short time periods often in the early years after the

technology came online This he says introduced biases farmers who adopted the

technology first tended to be wealthier and more educated and their farms were

already producing higher-than-average yields of conventional cotton They achieved

high yields of Bt cotton partly because they lavished the expensive GM seeds with care

and attention The problem now is that there are hardly any conventional cotton farms

left in India to compare GM yields and profits against says Stone Qaim agrees that

many studies showing financial gains focus on short-term impacts but his study

published in 2012 controlled for these biases and still found continued benefits

Bt cotton did not cause suicide rates to spike says Glover but neither is it the sole

reason for the yield improvements ldquoBlanket conclusions that the technology is a

success or failure lack the right level of nuancerdquo he says ldquoItrsquos an evolving story in

India and we have not yet reached a definitive conclusionrdquo

Transgenes spread to wild crops in Mexico UnknownIn 2000 some rural farmers in the mountains of Oaxaca Mexico wanted to gain

organic certification for the maize (corn) they grew and sold in the hope of generating

extra income David Quist then a microbial ecologist at the University of California

Berkeley agreed to help in exchange for access to their lands for a research project

But Quistrsquos genetic analyses uncovered a surprise the locally produced maize

contained a segment of the DNA used to spur expression of transgenes in Monsantorsquos

glyphosate-tolerant and insect-resistant maize

GM crops are not approved for commercial production in Mexico So the transgenes

probably came from GM crops imported from the United States for consumption and

planted by local farmers who probably didnrsquot know that the seeds were transgenic

Quist speculated at the time that the local maize probably cross-bred with these GM

varieties thereby picking up the transgenic DNA

When the discovery was published in Nature a media and political circus descended

on Oaxaca Many vilified Monsanto for contaminating maize at its historic origin mdash a

place where the crop was considered sacred And Quistrsquos study came under fire for

technical deficiencies including problems with the methods used to detect the

transgenes and the authorsrsquo conclusion that transgenes can fragment and scatter

throughout the genome Nature eventually withdrew support for the paper but

stopped short of retracting it ldquoThe evidence available is not sufficient to justify the

publication of the original paperrdquo read an editorial footnote to a critique of the

research published in 2002

Since then few rigorous studies of transgene flow into Mexican maize have been

published owing mainly to a dearth of research funding and they show mixed results

In 2003ndash04 Allison Snow a plant ecologist at Ohio State University in Columbus

sampled 870 plants taken from 125 fields in Oaxaca and found no transgenic

sequences in maize seeds

But in 2009 a study led by Elena Alvarez-Buylla a molecular ecologist at the National

Autonomous University of Mexico in Mexico City and Alma Pintildeeyro-Nelson a plant

molecular geneticist now at the University of California Berkeley found the same

transgenes as Quist in three samples taken from 23 sites in Oaxaca in 2001 and in two

samples taken from those sites in 2004 In another study Alvarez-Buylla and her co-

authors found evidence of transgenes in a small percentage of seeds from 1765

households across Mexico Other studies conducted within local communities have

found transgenes more consistently but few have been published

Snow and Alvarez-Buylla agree that differences in sampling methods can lead to

discrepancies in transgene detection ldquoWe sampled different fieldsrdquo says Snow ldquoThey found them but we didnrsquotrdquo

The scientific community remains split on whether transgenes have infiltrated maize

populations in Mexico even as the country grapples with whether to approve

commercialization of Bt maize

ldquoIt seems inevitable that there will be a movement of transgenes into local maize

cropsrdquo says Snow ldquoThere is some proof that it is happening but it is very difficult to

say how common it is or what are the consequencesrdquo Alvarez-Buylla argues that the

spread of transgenes will harm the health of Mexican maize and change

characteristics such as a varietyrsquos look and taste that are important to rural farmersOnce the transgenes are present it will be very difficult if not impossible to get rid of

them she says Critics speculate that GM traits that accumulate in the genomes of

local maize populations over time could eventually affect plant fitness by using up

energy and resources or by disrupting metabolic processes for example

Snow says that there is no evidence so far for negative effects And she expects that if

the transgenes now in use drift to other plants they will have neutral or beneficial

effects on plant growth In 2003 Snow and her colleagues showed that when Bt

sunflowers ( Helianthus annuus) were bred with their wild counterparts transgenic

offspring still required the same kind of close care as its cultivated parent but were

Just a minor side note but Im sure there are other genetic differences between the Mexican Maize

and corn planted in the US and elsewhere If these introduced gene sequences can migrate into

Mexican maize even though the planting of GM corn is banned then how much more must the

genes of non-GM but non-native Maize have migrated into the Mexican maize

It seems were talking about an artificial and irrelevant distinction

Just a minor side note but Im sure there are other genetic differences between the Mexican Maize

and corn planted in the US and elsewhere If these introduced gene sequences can migrate into

Mexican maize even though the planting of GM corn is banned then how much more must the

genes of non-GM but non-native Maize have migrated into the Mexican maize

It seems were talking about an artificial and irrelevant distinction

But says Glover ldquoit is nonsense to attribute farmer suicides solely to Bt cottonrdquo

Although financial hardship is a driving factor in suicide among Indian farmers there

has been essentially no change in the suicide rate for farmers since the introduction of

Bt cotton

That was shown by researchers at the International Food Policy Research Institute in

Washington DC who scoured government data academic articles and media reports

about Bt cotton and suicide in India Their findings published in 2008 and updated in

2011 show that the total number of suicides per year in the Indian population rose

from just under 100000 in 1997 to more than 120000 in 2007 But the number of

suicides among farmers hovered at around 20000 per year over the same period

And since its rocky beginnings Bt cotton has benefited farmers says Matin Qaim an

agricultural economist at Georg August University in Goumlttingen Germany who has

been studying the social and financial impacts of Bt cotton in India for the past 10

years In a study of 533 cotton-farming households in central and southern India

Qaim found that yields grew by 24 per acre between 2002 and 2008 owing to

reduced losses from pest attacks Farmersrsquo profits rose by an average of 50 over the

same period owing mainly to yield gains (see lsquo A steady rate of tragedy rsquo) Given the

profits Qaim says it is not surprising that more than 90 of the cotton now grown in

India is transgenic

Glenn Stone an environmental anthropologist at Washington University in St Louis

says that the empirical evidence for yield increases with Bt cotton is lacking He has

conducted original field studies and analyzed the research literature on Bt cotton

yields in India and says that most peer-reviewed studies reporting yield increases

with Bt cotton have focused on short time periods often in the early years after the

technology came online This he says introduced biases farmers who adopted the

technology first tended to be wealthier and more educated and their farms were

already producing higher-than-average yields of conventional cotton They achieved

high yields of Bt cotton partly because they lavished the expensive GM seeds with care

and attention The problem now is that there are hardly any conventional cotton farms

left in India to compare GM yields and profits against says Stone Qaim agrees that

many studies showing financial gains focus on short-term impacts but his study

published in 2012 controlled for these biases and still found continued benefits

Bt cotton did not cause suicide rates to spike says Glover but neither is it the sole

reason for the yield improvements ldquoBlanket conclusions that the technology is a

success or failure lack the right level of nuancerdquo he says ldquoItrsquos an evolving story in

India and we have not yet reached a definitive conclusionrdquo

Transgenes spread to wild crops in Mexico UnknownIn 2000 some rural farmers in the mountains of Oaxaca Mexico wanted to gain

organic certification for the maize (corn) they grew and sold in the hope of generating

extra income David Quist then a microbial ecologist at the University of California

Berkeley agreed to help in exchange for access to their lands for a research project

But Quistrsquos genetic analyses uncovered a surprise the locally produced maize

contained a segment of the DNA used to spur expression of transgenes in Monsantorsquos

glyphosate-tolerant and insect-resistant maize

GM crops are not approved for commercial production in Mexico So the transgenes

probably came from GM crops imported from the United States for consumption and

planted by local farmers who probably didnrsquot know that the seeds were transgenic

Quist speculated at the time that the local maize probably cross-bred with these GM

varieties thereby picking up the transgenic DNA

When the discovery was published in Nature a media and political circus descended

on Oaxaca Many vilified Monsanto for contaminating maize at its historic origin mdash a

place where the crop was considered sacred And Quistrsquos study came under fire for

technical deficiencies including problems with the methods used to detect the

transgenes and the authorsrsquo conclusion that transgenes can fragment and scatter

throughout the genome Nature eventually withdrew support for the paper but

stopped short of retracting it ldquoThe evidence available is not sufficient to justify the

publication of the original paperrdquo read an editorial footnote to a critique of the

research published in 2002

Since then few rigorous studies of transgene flow into Mexican maize have been

published owing mainly to a dearth of research funding and they show mixed results

In 2003ndash04 Allison Snow a plant ecologist at Ohio State University in Columbus

sampled 870 plants taken from 125 fields in Oaxaca and found no transgenic

sequences in maize seeds

But in 2009 a study led by Elena Alvarez-Buylla a molecular ecologist at the National

Autonomous University of Mexico in Mexico City and Alma Pintildeeyro-Nelson a plant

molecular geneticist now at the University of California Berkeley found the same

transgenes as Quist in three samples taken from 23 sites in Oaxaca in 2001 and in two

samples taken from those sites in 2004 In another study Alvarez-Buylla and her co-

authors found evidence of transgenes in a small percentage of seeds from 1765

households across Mexico Other studies conducted within local communities have

found transgenes more consistently but few have been published

Snow and Alvarez-Buylla agree that differences in sampling methods can lead to

discrepancies in transgene detection ldquoWe sampled different fieldsrdquo says Snow ldquoThey found them but we didnrsquotrdquo

The scientific community remains split on whether transgenes have infiltrated maize

populations in Mexico even as the country grapples with whether to approve

commercialization of Bt maize

ldquoIt seems inevitable that there will be a movement of transgenes into local maize

cropsrdquo says Snow ldquoThere is some proof that it is happening but it is very difficult to

say how common it is or what are the consequencesrdquo Alvarez-Buylla argues that the

spread of transgenes will harm the health of Mexican maize and change

characteristics such as a varietyrsquos look and taste that are important to rural farmersOnce the transgenes are present it will be very difficult if not impossible to get rid of

them she says Critics speculate that GM traits that accumulate in the genomes of

local maize populations over time could eventually affect plant fitness by using up

energy and resources or by disrupting metabolic processes for example

Snow says that there is no evidence so far for negative effects And she expects that if

the transgenes now in use drift to other plants they will have neutral or beneficial

effects on plant growth In 2003 Snow and her colleagues showed that when Bt

sunflowers ( Helianthus annuus) were bred with their wild counterparts transgenic

offspring still required the same kind of close care as its cultivated parent but were

less vulnerable to insects and produced more seeds than non-transgenic plants Few

similar studies have been conducted says Snow because the companies that own the

rights to the technology are generally unwilling to let academic researchers perform

the experiments

In Mexico the story goes beyond potential environmental impacts Kevin Pixley a

crop scientist and the director of the genetic resources program at the International

Maize and Wheat Improvement Center in El Batan Mexico says that scientists

arguing on behalf of GM technologies in the country have missed a crucial point

ldquoMost of the scientific community doesnrsquot understand the depth of the emotional and

cultural affiliation maize has for the Mexican populationrdquo he says

Tidy stories in favor of or against GM crops will always miss the bigger picture which

is nuanced equivocal and undeniably messy Transgenic crops will not solve all the

agricultural challenges facing the developing or developed world says Qaim ldquoIt is not

a silver bulletrdquo But vilification is not appropriate either The truth is somewhere in the

middle

The latest GMO folly is wheat which threatens to permanently damage human genetics by silencing

hundreds of genes throughout the body

Then theres a new study of Monstantos Roundup which shows it to be more toxic than officially

Even basic science cannot silencereverse ignorance or media spin

Nor can opinionated emphasis or capital letters truly refute valid reproducible and documented

facts - except in the mind of the lazily uninformed

Pity we see both of these constantly in every blog on earth

Just a minor side note but Im sure there are other genetic differences between the Mexican Maize

and corn planted in the US and elsewhere If these introduced gene sequences can migrate into

Mexican maize even though the planting of GM corn is banned then how much more must the

genes of non-GM but non-native Maize have migrated into the Mexican maize

It seems were talking about an artificial and irrelevant distinction

I have been eating chicken over half a century much of it canned More genetic feed (and who

I still do not hen-peck (though I do crow sometimes) do you

Our ancestors delivered our genes without introducing explosive genetic material at the acts of

conception The Algonquin Nation members thought 3 generations ahead with generosity and

gratitude rather than 3 months ahead with leverage from all and extraction to the very few You

may consider the producers due diligence as self-interested science and really what could go

wrong with that
