Barley gene space

A Japanese team led by Kazuhiro Sato of Okayama University participates in the International Barley Sequencing Consortium (IBSC) to produce a high resolution assembly of the majority of barley genes.

The barley genome is almost twice the size of that of humans and determining the sequence of its DNA has proved to be a major challenge. This paper published in Nature is a detailed overview of the functional portions of the barley genome, revealing the order and structure of its 26,000 genes. The findings are also described in the January 2013 issue of Okayama University e-Bulletin: http://www.okayama-u.ac.jp/user/kouhou/ebulletin/index.html

First cultivated more than 15,000 years ago, barley is the world's fourth most important cereal crop both in terms of area of cultivation and in quantity of grain produced.

The barley genome is almost twice the size of that of humans and determining the sequence of its DNA has proved to be a major challenge. This is mainly because its genome contains a large proportion of closely related sequences, which are difficult to piece together.

A Japanese team led by Kazuhiro Sato of Okayama University participated in the International Barley Sequencing Consortium (IBSC). They succeeded in producing a high resolution assembly of the majority of barley genes in linear order.

By developing and applying a series of innovative strategies that allowed them to circumvent these difficulties, IBSC describes the location of dynamic regions of the genome that carry genes conferring resistance to diseases. This achievement also highlights the unprecedented detail in the differences (15 million positions) between a range of different barley cultivars. The report provides a detailed overview of the functional portions of the barley genome, revealing the order and structure of its 26,000 genes.

Access to the assembled catalogue of gene sequences will streamline efforts to improve barley production by breeding varieties that are better able to withstand disease and deal with adverse environmental conditions such as drought and heat stress.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

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,...

Im Focus: Towards data storage at the single molecule level

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...

Im Focus: A space-time sensor for light-matter interactions

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.

The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
