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: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
