Engineered Crops: Transgenes Go Wild
نویسنده
چکیده
Genetically modified Agrostis stolonifera has escaped from cultivation. For the first time, a herbicide-resistant perennial weed has established itself in wild populations.

Risk assessment of genetically engineered crops: fitness effects of virus-resistance transgenes in wild Cucurbita pepo.
The development of crops genetically engineered for pathogen resistance has raised concerns that crop-to-wild gene flow could release wild or weedy relatives from regulation by the pathogens targeted by the transgenes that confer resistance. Investigation of these risks has also raised questions about the impact of gene flow from conventional crops into wild plant populations. Viruses in natura...
متن کاملSpread of engineered genes to wild relatives.
Over the past 20 years, it has become possible to isolate genes from microbes, plants, and animals and to insert them into a range of plant species. During the next two decades, it is likely that genetically engineered crops will become widespread in agriculture. This presents new opportunities for making plants resistant to pests and diseases, better able to withstand stressful environments, a...
متن کاملEnvironmental Effects of Genetically Engineered Woody Biomass Crops
The use of genetically engineered crop plants has raised concerns about the risks these crops pose to natural and agricultural ecosystems. The potential environmental hazards of transgenic woody biomass crops is discussed, and based on the biology of these crops and their transgenes, recommend a scientific framework for assessing risk. The potential impacts of transgenes based on both character...
متن کاملGenetic and ecological consequences of transgene flow to the wild flora.
Gene flow from crops to wild relatives by sexual reproduction is one of the major issues in risk assessment for the cultivation of genetically engineered (GE) plants. The main factors which influence hybridization and introgression, the two processes of gene flow, as well as the accompanying containment measures of the transgene, are reviewed. The comparison of risks between Switzerland and Eur...
متن کاملVoter Model and Biased Voter Model in Heterogeneous Environments
With the rapid adoption of transgenic crops, gene flow from transgenic crops to wild relatives through pollen dispersal is of significant concern andwarrants both empirical and theoretical studies to assess the risk of introduction of transgenes into wild populations. We propose to use the (biased) voter model in a heterogeneous environment to investigate the effects of recurrent gene flow from...
