Reference genome

The IWGSC Reference Wheat Genome project aims at producing a high quality reference genome sequence of the bread wheat genome cv. Chinese Spring that is anchored to the genetic maps, integrates different data resources and provides automated and manual annotation of genes and genomic features.

Since June 2016 and the release of the IWGSC WGA v0.4, the genome assembly has been further refined to produce a IWGSC RefSeq v1.0 assembly through integration of IWGSC chromosome-based sequences and resources. This assembly is available for download and BLAST at the IWGSC wheat data repository at URGI.

The IWGSC RefSeq v1.0 is an integration of the IWGSC WGA v0.4 with IWGSC chromosome-based and other resources, including but not limited to:

  • Physical maps for all chromosomes;
  • Sequenced BACs for 8 chromosomes (1A, 1B, 3B, 3D, 6B, 7A, 7B, 7D) and partial MTP BAC sequences for 2 chromosome arms (4AL, 5BS);
  • MTP BAC WGPTM sequence tags for all chromosomes, except 3B;
  • BioNano optical maps (7A, 7B, 7DS);
  • Alignment to RH maps (D chromosomes); and
  • GBS map of the SynOp RIL population CsxRn genetic map (INRA).

The automated gene annotation of IWGSC RefSeq v1.0, IWGSC RefSeq annotation v1.0 is also available on open access at URGI, it includes structural annotation (genes, transposable elements, ncRNAs), functional annotation, varietal SNPs, RH maps, GBS maps and optical maps. IWGSC RefSeq annotation v1.1 further includes genes and RNAseq mapping.
