The debate over genetically modified organisms (GMOs) is heated. One of the arguments against them is that it is unnatural to mix genes from different species. However, research in Lund, Sweden, shows that genetic modification can take place naturally among wild plants.
“In our research group we have suspected this for some time, and now my colleague Pernilla Vallenback has used DNA analysis to show that this is indeed the case”, says Professor Bengt O. Bengtsson at the Department of Biology at Lund University.
The research group on evolutionary genetics has discovered that a gene for the enzyme PGIC has been transferred into sheep’s fescue (Festuca ovina) from a meadow grass, probably Poa palustris, a reproductively distinct species. The DNA analyses also show that only a small part of a chromosome was transferred. This is the first proven case of the horizontal transfer of a gene with known function from the nucleus of one higher plant to another.
“Unfortunately, we don’t know exactly how the gene jump between the species occurred, which is not surprising as it took place perhaps 700 000 years ago. The most plausible explanation is that the gene was transmitted by a parasite or pathogen, such as a virus, perhaps with the help of a sap-sucking insect”, says Professor Bengtsson.
If gene jumps can occur naturally between plants belonging to different species, does this mean that there is no longer any reason to oppose genetically modified crops? According to Bengt O. Bengtsson, the answer is far from simple. He notes that the new results are interesting and important, but they do not say much about what is right or wrong in society.
“Many fear genetically modified crops because they believe that they may lead to unwanted gene spread in nature. This argument does not impress me. I sympathise, however, with the unease over the increased use of patents and monopolising practices in plant breeding. That is why it is so important that free and commercially independent research on plant genetics can be carried out in universities”, says Bengt O. Bengtsson.
The research has been published in the scientific journal PLoS One (doi: 10.1371/journal.pone.0013529).For more information, please contact: Bengt O. Bengtsson, Lund University

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
