Basic research enhances potential for cultivation in extreme climates

09.05.2011
Research on gene expression has resulted in plants that can survive drought, high salt concentrations, and infections. This opens the possibility of forestry in harsh climates. The plants produce more leaves than usual, which mean that they can yield more food per plant. These are the findings of researchers at Umeå University in Sweden in an article in the Proceedings of the American Academy of Sciences, PNAS.

All living organisms are dependent on water, but this is especially true for plants. Limited access to water is one of the decisive factors for humans to be able to survive in large parts of the earth. The development of plants (crops) with greater tolerance for drought is of great importance for more people to be able to live a decent life.

In a pure basic research project, where the goal was to understand how cells regulate protein expression, scientists in Umeå have now taken a giant step forward on the road to developing plants with greater resistance to drought, infections, and high concentrations of salt. By deactivating a gene that codes for a protein that is part of the so-called mediator complex in the plant mouse-ear cress, the researchers have shown that these plants evince a much greater ability to survive drought. At the same time, they have stronger resistance to high salt concentrations and their blooming is delayed, which indirectly leads to increased leaf production.

The research project is a collaboration between scientists at the Department of Medical Biochemistry and Biophysics at Umeå University and the Department of Forest Genetics and Plant Physiology and the Department of Microbiology at the Swedish University of Agricultural Sciences (SLU).

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
