Genome Sequencing Project

The effort to determine the nucleotide sequence of barley suffers from one impediment. The genome size of barley, 5000 Mbp, is larger than human, with all of the associated technical and informatic difficulties encountered during the Human Genome Initiative. As noted with wheat, barley researchers have made the strategic decision to build a physical map of the genome with as great a locus density as possible and to compare this with rice. The overview of the current state of this endeavor is available. The next step is to determine the nucleotide sequence of the transcriptome before committing funds and personnel toward determining the nucleotide sequence of the entire genome.

The aforementioned decisons have been implemented in a concerted effort in both North America (North American Barley Genome Project, USA and North American Barley Genome Mapping Project, Canada) and the EU [Plant Genome Resources Center (Germany) and Scottish Crop Research Institute (the United Kingdom)] to create a library as complete as possible composed of ESTs, STSs, and other molecular markers (each a randomly picked genomic DNA fragment that hybridizes with a unique pattern of restriction endonuclease fragments). These molecular markers have been, and will continue to be, instrumental in the effort to create a genetic map with marker density as great as possible.

The effort to build a physical map is supported by the barley BAC library programs at Washington State University, Scottish Crop Research Institute, and Maltagen.

Map Viewer Data

The Map Viewer data are provided by GrainGenes. There are two independently built consensus maps. There are two other maps, each from a separate mapping population, built by the North American Barley Genetic Mapping Project. More information about the data available can be found in the Barley Maps Help page.

GenBank Sequences

These searches provide all of the accessions from H. vulgare without the criterion of a particular subspecies.
