Lorenzo’s oil works for plants too

07.01.2003


Scientists at Long Ashton Research Station have identified a gene with a pivotal role in regulating seed germination. According to an article published in the January issue of BBSRC business, the Arabidopsis COMATOSE (CTS) gene, is vital for breaking seed dormancy. It is also analogous to the human X-ALD gene, which featured in the 1992 film "Lorenzo’s oil". Treatment of cts mutants with a plant version of Lorenzo’s oil cures their inability to germinate.



The researchers were investigating the genetic control of germination, a key transition in the life of a plant. Once they had cloned the CTS gene, they realised that is analogous to the human adrenoleukodystrophy (ALD) gene, mutation of which results in the build-up of very long chain fatty acids (VLCFAs) and ALD disease. Like human ALD sufferers, cts mutant seeds suffer from a variety of effects including inappropriate accumulation of VLCFAs. They are also unable to germinate. Lorenzo’s oil was developed by Augusto Odone for his son, who is an ALD sufferer, and was recently proven effective for the treatment of pre-symptomatic ALD patients. "We wondered whether Lorenzo’s oil would work for plants too" says team leader, Dr Mike Holdsworth. Sure enough, when he treated cts mutant seeds with a similar mixture of oils, the seeds became able to germinate.

The Long Ashton researchers believe that CTS protein is important as a fatty acid transporter, but may also have a key role as a regulator of germination. They are continuing to investigate CTS in Arabidopsis, but are also interested in crops such as wheat and oilseed rape, where dormancy levels are associated with quality and performance.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
