The Reference Genomes for Aegilops tauschii (AL8/78), Ae. speltoides (Y2032) and Triticum aestivum (AK58)

Wheat is a most important food crop in the world. Common wheat is a hexaploid species, with three subgenomes, A, B and D. The A subgenome donor is T. urartu, D genome donor is Ae. tauschii, and B genome donor is not clear up to now but more close to Ae. speltoides. Wheat had been a leading crop in research for long period history before the genomics era. However, it has lagged behind rice, maize, soybean and many other crops for lack of genome sequence information due to its large and complicated genome. The rapid development of sequencing and assembling techniques provide an opportunity to solve this issue. We integrated the most recent sequencing and assembling techniques, high-throughput next generation and third generation sequencing, 10x library construction, NRgene assembling, Hi-C, and high density genetic map, to work on wheat genome sequencing and assembling including Ae. tauschii, Ae. speltoides and a leading commercial wheat variety, Aikang58. We have provided comprehensive information of their genome components which will serve as wheat genome references. In addition, we focus on TE analysis, including their components, distribution and their association with genome shaping, genome evolution, gene expression, pseudogenes, methylation and genetic recombination. The detailed results will be presented.
