“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”.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
