A better understanding of gene flow

23.06.2005


Scientists will today explain to a meeting in London how their research has greatly improved our understanding of the flow of genetic material between organisms in the environment. Outcomes from the Gene Flow in Plants and Microorganisms Initiative, funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and the Natural Environment Research Council (NERC), will be valuable in informing the future of both conventional and GM crops.

The outcomes of the initiative include the finding that separation distances of around 100m between GM and conventional crops can meet most impurity thresholds and restrict the transfer of genetic material into the environment. Researchers also found that gene transfer from GM organisms to soil bacteria is vanishingly small and highly unlikely.

However, scientists examining the likelihood of gene transfer from conventionally-bred commercial oil seed rape to its waterside wild relative, Bargeman’s Cabbage, Brassica rapa, found that transfer was not rare. In fact, they estimated that around 32,000 oil seed/B. rapa hybrids are produced in the UK every year.



Another project explored how the activity of genes transferred into plants could be made more predictable. The researchers found that introducing traits by GM methods can have less impact on overall gene expression than conventional plant breeding.

The findings are the result of a five-year £4.5M initiative to increase knowledge of what happens when new or ‘foreign’ genes are inserted into an organism’s genome, what mechanisms control the insertion, whether inserted genetic material can transfer between organisms, and if so what the consequences of gene flow would be.

Professor Phil Dale, Chair of the Initiative Steering Group, said, “The findings of the Gene Flow Initiative are not just important in informing policy on GM crops but for conventional farming and plant breeding as well. Before research under this initiative began we had very little idea of how genetic material flowed in the environment but we are now much better placed for the future.”

Scientists involved in the initiative will be explaining the research and its outcomes at a Media Briefing.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.

Im Focus: Safe glide at total engine failure with ELA-inside

On January 15, 2009, Chesley B. Sullenberger was celebrated world-wide: after the two engines had failed due to bird strike, he and his flight crew succeeded after a glide flight with an Airbus A320 in ditching on the Hudson River. All 155 people on board were saved.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
