Would you like gene chips with your salad?

12.04.2002


The first public release of plant gene chip information is being launched at the Society for Experimental Biology conference in Swansea on Friday 12th April. Scientists from the Nottingham Arabidopsis Stock Centre (NASC), part of a multi-million pound resource network, will announce a newly accessible plant gene chip database which is available through the internet.



Unlike in GATTACA, where a drop of Ethan Hawke`s blood or an eyelash could tell you what genes he had, gene chips can tell you much more; not only which genes are there, but also how active they are, and therefore - what they may be doing.

Gene chips are produced in a similar manner to silicon chips, but instead of wires and transistors, the chips are covered with nucleotides and `virtual genes`. These chips allow scientists to take a small sample of an organism and then electronically show the simultaneous state of thousands of the RNA products from genes in that organism. This potentially gives you a `barcode` for the plant or animal and can be used in applications stretching from basic research to the real-time effects of GM manipulation, providing an exhaustive `contents` list for a transgenic organism. The `barcode` allow you to take a snapshot of the state of an organism telling you, for example, which genes are switched on in response to different exposures of light in a flower. The data is generated using Affymetrix gene chip technology and has been one of the hottest applications in the biological community for the last few years.


The gene chip is currently the only available chip for plants and covers the model plant Arabidopsis, at present covering 8000+ genes, to be increased to the plant`s full complement of 25 000 genes later this year. Arabidopsis is widely used in plant research because it is the only plant with a fully published and publicly available genome sequence.

"It is now possible to take a GM plant, compare it to a standard plant using gene chips, and precisely see ALL of the changes that have occurred. This takes away a great deal of the unknowns in genetic manipulation and will make the analysis of trangenic crops a more exact science," says Dr Sean May, director of NASC.

Im Focus: An ultrafast glimpse of the photochemistry of the atmosphere

Researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have explored the initial consequences of the interaction of light with molecules on the surface of nanoscopic aerosols.

The nanocosmos is constantly in motion. All natural processes are ultimately determined by the interplay between radiation and matter. Light strikes particles...

Im Focus: Shaping nanoparticles for improved quantum information technology

Particles that are mere nanometers in size are at the forefront of scientific research today. They come in many different shapes: rods, spheres, cubes, vesicles, S-shaped worms and even donut-like rings. What makes them worthy of scientific study is that, being so tiny, they exhibit quantum mechanical properties not possible with larger objects.

Researchers at the Center for Nanoscale Materials (CNM), a U.S. Department of Energy (DOE) Office of Science User Facility located at DOE's Argonne National...

Im Focus: Novel Material for Shipbuilding

A new research project at the TH Mittelhessen focusses on the development of a novel light weight design concept for leisure boats and yachts. Professor Stephan Marzi from the THM Institute of Mechanics and Materials collaborates with Krake Catamarane, which is a shipyard located in Apolda, Thuringia.

The project is set up in an international cooperation with Professor Anders Biel from Karlstad University in Sweden and the Swedish company Lamera from...

Im Focus: Controlling superconducting regions within an exotic metal

Superconductivity has fascinated scientists for many years since it offers the potential to revolutionize current technologies. Materials only become superconductors - meaning that electrons can travel in them with no resistance - at very low temperatures. These days, this unique zero resistance superconductivity is commonly found in a number of technologies, such as magnetic resonance imaging (MRI).

Future technologies, however, will harness the total synchrony of electronic behavior in superconductors - a property called the phase. There is currently a...

Im Focus: How Do the Strongest Magnets in the Universe Form?

How do some neutron stars become the strongest magnets in the Universe? A German-British team of astrophysicists has found a possible answer to the question of how these so-called magnetars form. Researchers from Heidelberg, Garching, and Oxford used large computer simulations to demonstrate how the merger of two stars creates strong magnetic fields. If such stars explode in supernovae, magnetars could result.
