The CerealsDB web-site was created by members of the Functional Genomics Group at the University of Bristol. The site provides a range of facilities for the study of the wheat genome. The site has been designed with breeders in mind, and we hope that is will be easy and straightforward to use. Principally the site is aimed at those who wish to obtain information about SNP markers; e.g., the sequence upon which they are based, obtain primers used for their identification, identify the haplotypes of common UK varieties. These publicly funded resources are available as an on-line, searchable database (please see "Important Note" box to the right of this page).
The last update to the database was February 2020.
27/09/19 - Please note: A large update in genotyping data is now available, click here to access.
The information regarding SNP markers is divided by platform:
Along with researchers at Affymetrix, we have developed both an '820,000' and a '35,000' 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.
The iSelect Array contains over 80,000 SNP loci of which 44,000 have been mapped.
We have optimised KASP technology to develop a SNPs database for wheat. KASP technology facilitates high throughput array based detection of sequence polymorhpisms.
In a continuing effort to support wheat breeders and the wheat research community, we have partnered with Life Technologies to design a collection of 4,800 TaqMan® SNP Assays for varietal markers within the wheat genome.
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.
Downloadable genome sequence reads
Over 85 gigabases of genomic 454 sequences (equivalent to 5x genome coverage) of Chinese Spring is available to be downloaded.
