Hebrew University researchers succeed in improving plants’ abilities to cope with saline conditions

14.06.2007
A method for increasing plants’ tolerance to salt stress and thus preventing stunted growth and even plant death has been developed by researchers at the Hebrew University of Jerusalem. The method has significant consequences for dealing with soil salinization, which is an acute problem for a wide range of crops in different regions of the world, including Israel.

The problem is largely exasperated by intense agriculture and irrigation. Salinity drives the plant into water deficit and is accompanied by toxicity of sodium and chloride ions, resulting in restricted growth and reduction in yield. Moreover, salt stress causes a secondary oxidative stress, resulting in the more severe cases in plant death.

Through detailed laboratory studies, Prof. Alex Levine and his Ph.D. student Yehoram Leshem, of the Department of Plant and Environmental Sciences at the Alexander Silberman Institute of Life Sciences at the Hebrew University, were able to achieve a new understanding of the specific mechanisms by which plants deal with salt stress conditions.

Based on this knowledge, and through implementation of genetic manipulation techniques, Levine and Leshem were successful in significantly reducing the self-induced membrane damage that takes place under the plants’ stressful conditions. The altered plants were also shown to have greater salt tolerance.

The work by Levine and Leshem – published in a recent article in the Proceedings of the National Academy of Sciences (PNAS) in the U.S. -- not only has opened new insights into a basic understanding of plant responses to salt stress, but also points the way to new applicative pathways for plant breeders to improve salt tolerance in a broad spectrum of agricultural crops. It thus represents a significant step forward that can bring great economic and social benefit to many nations of the world.

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...
