Better wheat varieties in the future? Wheat genome shows resistance genes easy to access
http://feeds.sciencedaily.com —
Scientists have developed a physical map of wheat's wild ancestor, Aegilops tauschii, commonly called goatgrass. It's the first huge step toward sequencing the wheat genome -- a complete look at wheat's genetic matter. The work showed among other things, that most resistance genes seem to lie at the ends of chromosomes and can be easily accessed. The findings can lead to breeding of more producti

Biologists propose a new research roadmap for connecting genes to ecology
http://feeds.sciencedaily.com —
A team of researchers is proposing a new investigative roadmap for the field of evolutionary developmental biology, or "evo devo," to better understand how innovation at the genetic level can lead to ecological adaptations over time. Evo devo seeks to understand the specific genetic mechanisms underlying evolutionary change.

Evolving genes lead to evolving genes: Selection in European populations of genes regulated by FOXP2
http://feeds.sciencedaily.com —
Researchers have designed a method that can universally test for evolutionary adaption, or positive (Darwinian) selection, in any chosen set of genes, using re-sequencing data such as that generated by the 1000 Genomes Project. The method identifies gene sets that show evidence for positive selection in comparison with matched controls, and thus highlights genes for further functional studies.

Fishing for solutions: Examining function of all genes in the zebrafish genome to benefit human health
http://feeds.sciencedaily.com —
Equipped with the zebrafish genome, researchers have designed a method to assay the function of each and every gene and to explore the effects genetic variation has on zebrafish. So far the team has generated one or more mutations in almost 40% of all zebrafish genes.

In triplicate, genes make maize tolerant to toxic soil
http://feeds.sciencedaily.com —
Rendering some of the world’s toxic soils far less unfriendly, researchers are learning to grow stress-tolerant crops on formerly non-farmable land.
