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 Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
