“Wheat is tremendously important” says Dr Graham Moore (project leader at the JIC), “it is a staple crop for a large proportion of the world’s population as well as the most important crop in North European agriculture. Unfortunately, the genome of wheat is very complex and that makes both studying its biology and using genetics to improve the quality of the crop, very difficult. The comprehensive genetic libraries that we are making available will help scientists and breeders who are seeking to improve the performance of wheat in agricultural systems around the world”.
The genome of wheat is 5x larger than that of humans and includes a total of 150,000 genes. The BAC libraries are collections of fragments of the wheat genome. Each fragment on average carries 1 or 2 genes and in total there are over 1.2 million fragments in the libraries. After years of work, exchange visits between laboratories and at a cost of millions of Euros, the combined efforts of British and French researchers have reduced the complex genetics of wheat to two large freezers full of tiny test-tubes. Pooling the British and French research efforts has had two major benefits. Firstly, it has dramatically shortened the time taken to produce a complete gene library. Secondly, it has resulted in several slightly different libraries, providing the researchers with some additional information not available from a single library.
“The USA would like a copy of the British/French library and China, Japan, and Australia have expressed interest in using it” says Dr Boulos Chalhoub (project leader at INRA). “This shows just how valuable a resource we have developed and in time we expect to see these libraries helping researchers and breeders in their continuing pursuit of both global food security and environmentally sustainable agriculture. We would like to see this collaboration set the pattern for the future, with major international cooperative efforts on a wide variety of crops, developing genetic resources that are openly accessible to academic and commercial organisations”.

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...
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...

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.

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.
