Naturally GM: Crops steal genes from other species to accelerate evolution

E-Mail
Grass crops are able to bend the rules of evolution by borrowing genes from their neighbours, giving them a competitive advantage, a new study has revealed.
Research, led by the University of Sheffield, is the first to show that grasses can incorporate DNA from other species into their genomes through a process known as lateral gene transfer.
The stolen genetic secrets give them an evolutionary advantage by allowing them to grow faster, bigger or stronger and adapt to new environments quicker. These findings could inform future work to create crops that are more resistant to the effects of climate change and help to tackle food security problems. ....

Natural GM: how plants and animals steal genes from other species to accelerate evolution

Little did biologist Gregor Mendel know that his experiments with sweet peas in a monastery garden in Brno, Czech Republic, would lay the foundations for our understanding of modern genetics and inheritance. His work in the 19th century helped scientists to establish that parents pass their genetic information onto their offspring, and in turn, they pass it on to theirs.
Indeed, this premise forms the basis of much of our understanding of evolution. But we now know that this process is not sacrosanct and some of our most widely grown crops may be fiddling the system by supplementing their genetic information with stolen genetic secrets. Our new study, published in New Phytologist, shows that this does in fact happen in grasses. ....

Grasses pass genes from one species to another but we don't know how

jozef sedmak/Alamy
It’s freecycling, but for DNA. Grasses routinely pass genes from one plant to another, even if they belong to distantly related species.
“We’ve shown that lateral gene transfer is a widespread process in grasses,” says Luke Dunning at the University of Sheffield in the UK. The finding adds to the evidence that DNA can be transferred from one complex organism to another, and that this can benefit the organism that receives it.

Biologists have known for decades that single-celled organisms like bacteria can pass genes around: a process called lateral gene transfer or horizontal gene transfer. But as recently as 20 years ago it was thought that this didn’t happen in organisms with more complex cells, known as eukaryotes – the group that includes all animals, plants and fungi. ....
