Approval of the Amflora could signal a fresh approach to genetically modified organisms.

Declan Butler

The European Comm ission last week approved Amflora — a genetically modified (GM ) potato developed by Germ an chemical com pany BASF. The potato — engineered to produce a form of that is better for some industrial purposes in, for example, paper manufacturing, adhesives and textiles — is the first GM crop to be approved for cultivation in the (EU) for 12 years. 's MON 810 maize (corn), which is engineered to be resistant to the European corn•borer caterpillar, was licensed in 1998.

The sluggish pace of approval for GM crops means that whereas 134 million hectares of GM crops were planted worldwide last year, less than 100,000 hectares of those were in the agricultural powerhouse that is the EU. Nature looks at the reasons why so few GM crops have been approved in Europe, and if that is now set to change.

What's responsible for the EU blockage of GM crops?

The EU•wide system for approving genetically modified organisms (GMOs) isn't working. In principle, when the EU approves a GM crop for cultivation, companies and farmers across all member states have the right to plant it. But getting crops approved requires a 'qualified majority' of the 27 member states that make up the European Council in favour — at least 255 from a total of 34 5 v otes — so op p osition b y a few cou n tries can b lock th e in trod u ction of a crop across the entire bloc. If the council fails to approve it, as was the case with Amflora, the decision rests with the .

Does the approval of Amflora signal a change?

Yes and no. and have already said that they will defy the commission and refuse to allow the crop to be grown, and other countries are likely to follow. In theory, the commission can force such countries to comply, but that has become a political non•starter. Last year, the commission attempted to force , , Austria and Hungary to lift bans on growing MON 810 maize, but couldn't muster the majority vote of member states needed.

At the moment, six countries — Austria, France, , Greece, Hungary and Luxembourg — have GMO bans in place through the use of 'safeguard clauses'. Such clauses allow member states to restrict or prohibit specific GMOs that are already approved by the EU if they claim to have some evidence that nature.com/…/news.2010.112.html 1/4 16-3-2010 A new dawn for transgenic crops in E… the crops might pose a risk to human health or the environment. Often, however, member states are simply responding to public pressure at home.

But the commission's approval of Amflora may signal that it is willing to use its executive authority to push through authorizations of GMOs that haven't been Amflora potatoes have been approved able to gain approval through the usual voting for cultivation in the European Union. procedure. The commission has indicated that it is BASF likely to take decisions soon on the stalled renewal of MON 810's licence, and on the approval of three other m aize strains — tw o insect­resistant varieties m ade by and Pioneer, and a Monsanto strain that is resistant to glyphosate•based herbicides such as 'Roundup'.

And what about states that refuse to comply?

After the commission's bruising defeat in trying to lift the bans of individual nations, it now looks set to take a pragmatic approach that might formally allow countries to opt out of growing GM crops. Few details of the proposals, which are due to be announced this summer, are available yet. But some reports suggest that the commission could continue to approve GMOs across the EU on the basis of scientific advice from the European Food Safety Authority (EFSA), its independent risk­assessment body in Parma, Italy — and then let member states decide whether to grow the crops or not. This sort of approach could take the heat out of the EU debate on GMOs, spur more approvals and allow countries that wish to grow GMOs to do so.

The Amflora potato approval has stirred up a lot of opposition. Why is this?

The potato is controversial not because of its modified starch but because it contains marker genes that confer resistance to the antibiotics kanamycin and neomycin. Breeders of GM crops use antibiotic•resistance markers to spot which plants have successfully incorporated . They attach the antibiotic•resistance gene onto the desired trait genes, and then treat the transgenic seedlings with antibiotics, which kills those plants that haven't taken up the foreign genes. Environmental groups and some countries have had long•standing concerns about the risk of genes spreading from crops to bacteria and increasing bacterial antibiotic resistance.

What does the science say about that risk?

The EFSA considered this in the context of the Amflora application in 2005, and concluded that the risk of transfer of antibiotic resistance from plants to bacteria was remote, and that bacteria resistant to the antibiotics were already present in soil, animals and humans. That position was restated in a broader safety assessment of antibiotic•resistance markers, published by EFSA's GMO and BIOHAZ panels in June 2009. But on that occasion, two scientists, both from the BIOHAZ panel, formally disagreed with the conclusions. They argued that the risk of gene transfer might be less than remote, and that introducing genes that confer resistance to antibiotics that are used, for example, to treat multiply drug•resistant nature.com/…/news.2010.112.html 2/4 16-3-2010 A new dawn for transgenic crops in E… tuberculosis simply isn't a good idea.

The reason the problem arises at all is because ADVERTISEMENT Amflora is a first•generation GM crop that was developed in the late 1980s. Modification technologies developed since then allow the use of alternatives to antibiotic•resistance markers, or allow such markers to be spliced out of the plant before cultivation. Indeed, although the EU, the World Health Organization and many health bodies accept that the risk of transfer of antibiotic resistance seems low, they have called for antibiotic•resistance markers in GMOs to be phased out.

More broadly, other experts say that much more publicly funded research on GMOs would lead to greater public confidence in risk assessments, which are currently heavily dependent on industry studies.

Where and when will the Amflora potato be planted?

BASF has said that it only intends to grow the potatoes in countries that want it — the company will begin planting Amflora this year on a few dozen hectares in Germany, and the . If the European Commission succeeds in its plans to break the GMO deadlock, many more hectares, and many more varieties of GM crops, may soon be growing in Europe. Comments

Social acceptance of GMOs should come from the heart of the people & not by forcefull #9652 implimentation of rules & regulation which is not going to help.Public have faith only on research outcome of public funded research not on business oriented companies whose aim is to make money only.Indian government has taken right decision by declining bt•brinzal & research out come of private companies.EU need to take utmost precoution in this step.
