Sicilian enters British genetic language

14.11.2008
A scientific team from the John Innes Centre and University of St Andrews has identified a key gene that was transferred from a Sicilian plant into a close relative in Britain, showing how genetic cross-talk between species can be important for evolution.

The researchers unravelled the remarkable history of an Italian interloper, a close relative of the common British weed Groundsel, that was first brought to the UK 300 years ago. In an amazing piece of genetic detective work, to be published in Science on Friday, they tracked down a small region of DNA in the British weed that came from its Sicilian relative.

This region of DNA modifies the flowers, making the weed more attractive to pollinators. The results demonstrate how natural genetic exchanges can allow important traits to be transferred between species, much as a word from one human language might be usefully incorporated into another.

This goes against the typical view of evolution as a one-way street in which each species evolves as a separate, independent genetic lineage. Instead, hybridisation between closely related forms may allow evolutionary cross-talk in which valuable genes can be exchanged and preserved. The result is greater flexibility and potential for diversity during evolution.

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...
