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.

Open Source Seed Initiative – A Welcome Boost to Global Crop Breeding
A team of plant breeders, farmers, non-profit agencies, seed advocates, and policymakers have created the Open Source Seed Initiative.
Four Newly-Identified Genes Could Improve Rice
A Japanese research team have applied a method used in human genetic analysis to rice and rapidly discovered four new genes that are potentially significant for agriculture. These findings could influence crop breeding and help combat food shortages caused by a growing population.
“Amazing Protein Diversity” Discovered in Maize
The genome of the corn plant – or maize, as it’s called almost everywhere except the US – “is a lot more exciting” than scientists have previously believed. So says the lead scientist in a new effort to analyze and annotate the depth of the plant’s genetic resources.
Invasive Species Could Cause Billions in Agriculture Damages
Invasive insects and pathogens could be a multi-billion-dollar threat to global agriculture and developing countries may be the biggest target, according to a team of international researchers.
Genetic Research Can Significantly Improve Drug Development
With drug development costs topping $1.2bn (£850 million) to get a single treatment to the point it can be sold and used in the clinic, could genetic analysis save hundreds of millions of dollars?

It’s the journey, not just the destination that counts as a scientist when conducting research.
Scoliosis Linked to Disruptions in Spinal Fluid Flow
A new study in zebrafish suggests that irregular fluid flow through the spinal column brought on by gene mutations is linked to a type of scoliosis that can affect humans during adolescence.
More Research Needed to Ensure Gene Drive Safety
Gene-Drive modified organisms are not ready to be released into environment a new report calls for more research and robust assessment.
