1. URGI

    The Wheat Portal maintains databases and tools to study genetic and genomic wheat data. Data available from the Wheat Portal include chromosome survey sequences, reference sequences, physical maps, genetic maps, polymorphisms, genetic ressources, phenotypes and arrays. The portal also provides information on international wheat projects and access to analysis tools such as annotation pipeline.
  2. GigaDB

    GigaDB contains 133 discoverable, trackable, and citable datasets that have been assigned DOIs and are available for public download and use.
  3. WheatA genome

    The wheat A genome, as a basic genome of bread wheat and other polyploid wheats, is centrally important to the evolution, domestication, and genetic improvement of wheat. The progenitor of the A genome is the diploid wild einkorn wheat Triticum urartu. Here, we sequenced T. urartu (accession G1812) using a whole-genome shotgun strategy on the Illumina HiSeq 2000 platform, and assembled the genome using SOAPdenovo2 with 448.49 Gb of filtered high-quality sequence data. The genome assembly reached 3.92 Gb (without Ns) with a contig N50 length of 3.42 kb and 4.66 Gb (with Ns) with a scaffold N50 length of 63.69 kb . To facilitate gene prediction, we generated a 116.65 Mb transcriptome of T. urartu with 67.14 Gb RNA-Seq data from eight different tissues and treatments, and 49,935 assembled transcripts from six tissues using the Roche 454 sequencing platform. In total, we predicted 34,879 protein-coding gene models. The average gene size was 3,207 bp, with a mean of 4.7 exons per gene.
  4. WheatD genome

    A spontaneous hybridization of the wild diploid grass Aegilops tauschii (2n=14, DD) with cultivated tetraploid wheat Triticum turgidum (2n=4x=28, AABB) 8,000~10,000 years ago in the Fertile Crescent resulted in the bread wheat (Triticum aestivum; 2n=6x=42, AABBDD), one of the earliest cultivated crops in modern agriculture. We sequenced the 4.36-gigabase (Gb) genome of Ae. tauschii by generating ~90x genome coverage of short reads from a series of libraries with various insert sizes. The assembled scaffolds of high quality sequences represent 83.4% of the genome, in which 65.9% comprised of repetitive elements. Assisted with comprehensive RNA-Seq data, we identified 43,150 protein-coding genes, with 30,697 (71.1%) of them uniquely anchored to chromosomes based on an integrated density genetic map. A number of agriculturally relevant gene families, such as disease resistance, abiotic stress tolerance, and grain quality genes, were found to expand in Ae. tauschii. The draft genome of Ae. tauschii hence provides novel insights into its role in enabling environmental adaptation of common wheat and in defining the large and complicated genomes of wheat species.
