Now, in the 11 February issue of Nature, an international consortium led by the John Innes Centre, the US Department of Energy Joint Genome Institute, the US Department of Agriculture and Oregon State University present an analysis of the complete genome sequence of the wild grass Brachypodium distachyon.
Three different groups of grasses, represented by maize, rice and wheat, provide most of the grains that support human nutrition and our domesticated animals. The genomes of two of these three groups have been sequenced. Brachypodium distachyon is the first member of the third group, which contains key food and fodder crops such as wheat, barley and forage grasses, to be sequenced.
Analysis of the compact Brachypodium genome has provided new insights into how grass genomes evolve and expand and it has demonstrated how Brachypodium can be used to navigate the closely related yet far larger and more complex genomes of wheat and barley.
"Our analysis of the Brachypodium genome is a key resource for securing sustainable supplies of food, feed and fuel from established crops such as wheat, barley and forage grasses and for the development of crops for bioenergy and renewable resource production", stated Michael Bevan from the John Innes Centre."It is already being widely used by crop scientists to identify genes in wheat and barley, and it is defining new approaches to large-scale genome analysis of these crops, because of the high degree of conserved gene structure and organisation we identified".
Scientists at the John Innes Centre and their colleagues are working on projects aimed at enhancing food security and creating sustainable industries. The John Innes Centre, supported by the Biotechnology and Biological Sciences Research Council (BBSRC) and the John Innes Foundation, is committed to creating the resources and understanding needed for sustainable food and fuel production.

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
