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: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

Im Focus: Entangled atoms shine in unison

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
