The ability to promote agricultural and conservation successes in the face of rapid environmental change will partly hinge on scientists' understanding of how plants adapt to local climate.
To improve scientists' understanding of this phenomenon, a study in the Oct. 7, 2011 issue of Science helps define the genetic bases of plant adaptations to local climate. The National Science Foundation partly funded the study, which was conducted by Alexandre Fournier-Level of Brown University and colleagues.
The study involved growing a diverse panel of strains of the mustard plant, Arabidopsis, in various locations within its native range in Finland, Germany, England and Spain. Then, the genetic mutations increasing plant fitness in each of these locations were identified.
Results show that the preferred climate of each strain of Arabidopsis is conferred by the presence of a relatively small number of genes; different sets of genes control adaptability to different types of climates; and the presence of a particular set of climate genes in a single plant is not necessarily mutually exclusive to the presence of another. These findings mean that it may be possible to combine various sets of climate genes in a single Arabidopsis strain in order to generate a strain that would be able to thrive in multiple types of climates. Such adaptability would help the plant accommodate climate change.Media Contacts

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
