GrainGenes Hot Topics
The Hordeum Toolbox
THT was created for the Barley CAP project, to hold SNP genotyping
and phenotype data for association mapping in elite barley breeding lines.
The database and web interface were created by Julie Dickerson of Iowa
State University, and are now running at GrainGenes for long-term
Wheat Mapping Populations. A spreadsheet with information on the available wheat mapping populations, from Justin Faris, Feb 2010.
Barley, OPA2009, Consensus maps are online as interactive maps from BMC Genomics 2009, 10:582.
Bob McIntosh honored
Bob McIntosh was made an Officer of the Order of Australia on June 8, 2009, for "service to agricultural science in Australia
and internationally, particularly through research in the areas of wheat
genetics and rust disease and as an educator and mentor".
Barley SNP DatabaseSNPs in Affymetrix Barley Contigs (ABCs), with map positions.
Barley CAPThe barley Coordinated Agricultural Project (CAP) is a community effort of
30 scientists from 19 US institutions, to integrate and utilize
state-of-the-art genomic tools and approaches in barley breeding programs.
News about the project is posted at http://www.barleycap.org/news.htm.

European Triticeae Genomics Initiative (ETGI)
ETGI coordinates European efforts in barley and wheat physical mapping,
sequencing, high resolution genetic mapping, and development of populations
for trait mapping with QTLs and association genetics.

international collaboration on Fusarium head blight.
Wheat Genome Sequencing Consortium (WGSC)
Established to facilitate and coordinate international efforts
toward obtaining the complete sequence of the common (hexaploid) wheat genome.
WIRE, the Wheat Information REsource
The site for an NSF-supported wheat
mutagenesis project, using the DEALING (DEtecting Adduct Lesions IN the
Genome) technology. The project and the site are still new, but there are diamonds here already.

Physical Mapping of the Barley Genome
This database of Hordeum vulgare cv. Morex BAC contigs,
assembled via FPC, currently contains 22,000 clones assembled in 2300
contigs, corresponding to about 1/3 of the barley gene space. Data on
thousands of markers (cDNAs, gene fragments and overgo probes) mapped to the
BAC clones will be added soon.
Rice chromosomes vs. cereal genes
Physical (BAC/PAC) map of japonica chromosomes, aligned by BLAST with
mapped contigs and singletons from the NSF wheat EST project,
with contigs and singletons from the Wheat SNP project, and
with GenBank protein sequences of wheat, barley, rye, oat, and rice.
