  • GM maize contaminates non-GM crops in Uruguay

    Contamination of traditional maize crops planted near genetically modified (GM) maize fields may be common in Uruguay, where the cultivation of GM maize has been permitted since 2003, scientists have said. A study published in Environmental Biosafety Research (25 March) has found GM seedlings in three ...

  • Overcoming obstacles to GM crop adoption

    This policy brief, published by the UK's Parliamentary Office of Science and Technology (POST), examines the potential benefits and challenges of using genetically modified (GM) crops for agricultural development in the developing world, and highlights ...

  • Flexible management better for coexistence of GM and non-GM crops

    Flexible measures, such as pollen barriers, for regulating the cultivation of GM and non-GM crops in the same landscape are more likely to encourage the adoption of GM technology by farmers than rigid measures, such as isolation distances, according to a recent study. The EU has recommended guidelines1 for developing national strategies by all Member States for the coexistence of genetically ...

  • Carbon credits to be used to fund GM food crops

    US biotech firm Arcadia Biosciences has announced a plan to help fund the planting of genetically modified rice with carbon credits. The company will work with the Chinese government to give farmers who plant their crops carbon credits, which they can then sell on the global carbon trading market. Arcadia is touting its GM rice as a greener alternative to the regular crop. The plant has had a ...

  • Uganda starts `historic` trials on GM staple crops

    Ugandan researchers will carry out a series of field trials on some of the major food crops that have been genetically modified (GM), following several recent approvals by the Uganda National Biosafety Committee, despite a lack of clear legislation on commercialising any such products within the country. They will seek to develop both transgenic and conventional maize varieties tolerant to ...

  • Impact of volunteer GM maize on conventional crops is low

    A recent EU-supported study has analysed the development of volunteer or 'rogue' GM (genetically modified) maize plants in a conventional crop field. It finds that their numbers are low and do not exceed the EU's threshold of 0.9 per cent for incidental GM content. Scientific data on the role of maize volunteers on cross-pollination is limited. The most detailed studies have been conducted in ...

  • GM crops can thrive as climate warms

    Genetically engineering photosynthesis in plants could take advantage of rising global temperatures and increased levels of carbon dioxide, US scientists say. They believe this could achieve much higher yields on the same amount of land and help to stave off the prospect of widespread hunger as human populations increase. Researchers at ...

  • Steady increase in incidents of low levels of GM crops in traded food and feed

    The increased production of genetically modified crops around the globe has led to a higher number of incidents of low levels of GMOs being detected in traded food and feed, FAO said today. The incidents have led to trade disruptions between countries with shipments of grain, cereal and other crops being blocked by importing countries and destroyed or returned to the country of origin. The trace ...

  • Crossbreeding GM crops may increase fitness of wild relatives

    A new study has investigated the effects of interbreeding a genetically modified squash crop with its wild relative. The findings demonstrate that it could cause wild or weedy relatives to become more resistant to disease. Genetic Modification (GM) can be used to develop crops that are resistant to specific pests. However, there are concerns that if a GM crop interbreeds with its wild or weedy ...

  • Europe rejects GM crops as new report highlights 20 years of failures

    All 19 government requests for bans of GM crop cultivation have gone unchallenged by biotech companies, pathing the way for two thirds of the EU’s farmland and population to remain GM-free [1]. The growing opposition to GM crops coincides with a new Greenpeace report reviewing evidence of GM environmental risks, market failures, and increased pesticide use [2]. Greenpeace EU ...

  • Sloppy seed-sorting main culprit in GM crop escapes

    Careless handling of seeds may be the key reason for the unintended spread of genetically modified (GM) crops, a study has found. The discovery challenges the widespread belief that the main source of GM contamination is the transfer of pollen by bees from GM crops to non-GM counterparts in neighbouring fields. Human error during seed production and handling is the more likely culprit, say the ...

  • Earthworms decompose GM maize

    Pest-resistant genetically modified (GM) maize makes up an increasing proportion of maize grown commercially in the EU. A new study shows that earthworms may help break down the toxins produced by GM maize. GM maize (Bt-maize) plants are engineered to produce 'cry' proteins that are toxic to the European corn borer, a major insect pest responsible for corn crop losses. Recent studies have shown ...

  • Peru relaxes GM rules … for now

    After nine years of discussions, Peru's government has passed an agricultural biosafety regulation intended to promote biotechnological research and help the country's researchers catch up with other Latin American nations. The Biosafety Rules for the Agriculture or Forestry Sectors will regulate the research, ...

  • Pakistan debates GM cotton’s success

    Pakistan is beset by conflicting claims over the success of genetically modified (GM) cotton, now grown in over 90 per cent of the 2.5 million hectares under cotton. The GM cotton variety — also called Bt cotton because it contains a gene taken from the soil bacterium Bacillus thuringiensis that resists ...

  • GM rice `spreading illegally in China`

    Illegal genetically modified (GM) rice seeds have been found in several Chinese provinces by a government investigation, according to an environment ministry official. A joint investigation by four government departments discovered the seeds, attributing their presence to "weak management", according to the news agency Agence France-Presse (AFP). China has allowed ...

  • GM eggplant trials suspended in Philippines

    Field trials of genetically modified (GM) eggplant have been suspended following a dispute at one of the trial sites that led local officials to uproot 3,000 plants. Two of seven field trials of the plant — also known as Bt (Bacillus thuringiensis) brinjal — were halted last month (29 December), two weeks after local authorities in Davao City uprooted plants because researchers had ...

  • Cement develops an appetite for C02

    Three new studies illuminate the sheer complexity of the aspect of climate science known as the carbon cycle − how carbon dioxide gets into the atmosphere and out again. Sometimes, human agency is at work, but nature takes care of it anyway – as one of the studies reveals in the case of cement, the world’s most widely-used building material. Zhu Liu, postdoctoral scholar at ...

    Just under 20 years ago, when the issue of GMOs was first hitting the news, I was a dedicated anti-biotech activist. I believed that genetic modification was a dangerous technology that would harm the ...

  • Microbes `cheaper, fairer` for boosting yields than GM

    Adapting microbes that dramatically increase crop yields while reducing demand for fertilisers and pesticides through selective breeding or genetic engineering could be cheaper and more flexible than genetically modifying plants themselves, says an author of a report. Microbes, such as beneficial bacteria, fungi and viruses, could be ...

  • GM cotton genes found in wild species

    Genetically modified (GM) cotton genes have been found in wild populations for the first time, making it the third plant species — after Brassica and bentgrass  — in which transgenes have established in the wild. The discovery was made in Mexico by six Mexican researchers investigating the flow of genes to wild cotton populations of the species Gossypium hirsutum. They found ...
