This website, created by members of the Functional Genomics Group at the University of Bristol, is aimed at those who wish to obtain information regarding Single Nucleotide Polymorphism (SNP) in the genomes of bread wheat (Triticum aestivum) and its relatives
These resources are available as an on-line, searchable database. Via this website and associated publications, we have placed all the data related to each and every SNP, including available flanking sequences (usually 120 base pairs or greater), in the public domain. We hope that by making this information freely available without restriction, it will encourage other wheat geneticists to do likewise.
The last update to the database was September 2021.
THE WHEAT COMMUNITY NEEDS YOUR SNPS
As part of Bristol's contribution to the BBSRC funded Designing Future Wheat (DFW) programme, we have decided to update the Axiom 35K Wheat Breeders' Array (Allen et al., 2016). The new array will include space for SNPs of interest to members of the wheat community. Thus, if you have an allelic series for your favourite gene and would like it to be included on the array, submit it to us for inclusion.
Please be aware, like all work undertake by DFW, the array will be public, so please do not submit sequences which cannot be considered to be in the public domain.
For more information and to obtain an input form, go to the New Array page.
The information regarding SNP markers is grouped according to genotyping platform:
Along with researchers at Affymetrix, we have developed both an 820K and a 35K feature wheat SNP array. The data sets for these (Affymetrix code, Bristol SNP code and probe sequence containing the SNP ambiguity code) can be downloaded here.
We have optimised KASP technology to develop a SNPs database for wheat.
The iSelect Array contains over 80,000 SNP loci of which 44,000 have been mapped.

Draft genome assembly
A draft wheat genome assembly based on 5x coverage of 454 reads can be BLAST searched. Alternatively, the raw 454 reads may be searched using the same link.
