Mission statement
Barley (Hordeum vulgare L.) was one of the first domesticated cereal grains, originating in the Fertile Crescent over 10,000 years ago. Barley
ranks fifth in worldwide crop production and is widely cultivated in all temperate regions from the Arctic Circle to the tropics. In addition to its
geographic adaptability, barley is particularly noted for its tolerance to cold, drought, alkali, and salinity.
The barley genome - with 5.3 billion letters of genetic code - is one of the largest in cereal crops measuring about twice the size of the human
genome. Barley is a true diploid, thus, it is a natural archetype for genetics and genomics for the Triticeae tribe, including polyploid wheat, and
rye. Highly collaborative international efforts have produced a substantial body of genetic and genomic resources in the past several years.
The objective of IBSC is to physically map and sequence the barley gene space including the 5’ and 3’ regulatory regions of genes. The
central goal is to develop an ordered physical map linked to the genetic map in order to accelerate gene isolation and crop improvement and to
provide the basis for the longer-term goal of sequencing the barley genome.

Developing a physical map by High Information Content Fingerprinting (HICF) –
target: 15x haploid genome coverage
Research Agenda
Anchoring the physical map to the high-density and high-resolution genetic map
of barley: mapping of up to 15,000 barley genes, BAC end sequencing and
mapping, colinearity to model genomes
Sample sequencing the barley genome: Gene-enriched library sequencing
(GSS), contig- and sample-BAC sequencing
Contig-based and shotgun whole genome sequencing
Physical map construction:
HICF of 83000 gene-containing genes ongoing as collaborative project between UCR (TJ Close) and UC Davis (MC
Luo)
- funding available from NSF Plant Genome Research Program
10x genome coverage HICF ongoing as collaborative project between IPK, ACPTG and TU Munich
- funding available
