Genomic data from Triticum urartu - the progenitor of wheat A 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.
