About Brachypodium distachyon
In common with the model plant, Arabidopsis thaliana, Brachypodium distachyon has several features that recommend it as a model plant for functional genomic studies especially in the grasses. Traits that make it an ideal model include its small genome (~355 Mbp), small physical stature, a short lifecycle, and few growth requirements. Brachypodium is related to the major cereal grain species but is understood to be more closely related to the Triticeae (wheat and barley) than to the other cereals.

Analysis of the bread wheat genome using comparative whole genome shotgun sequencing
As part of the wheat genome analysis, we have aligned a set of identified Triticum aestivum (bread wheat) gene sequences and homoeologous SNPs (SNPs between the component A, B, and D genomes of wheat) against the Brachypodium distachyon genome.
Currently, the size and complexity of the wheat genome precludes a chromosome-scale assembly. However, significant sequences resources have been used to produce a gene-space assembly, included here in the syntenic context of brachypodium, a model cereal and pooid relative of wheat.
Sequences of diploid progenitor and ancestral species permitted homoeologous SNPs to be classified into two groups, 1) SNPs that differ between the A and D genomes (where the B genome is unknown) and, 2) SNPs that are the same between the A and D genomes, but differ in B.
The wheat gene alignments and the projected wheat SNPs are available on the Location view, as additional tracks under the "Wheat SNPs and alignments" section of the "Configure This page" menu.
