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: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
