The bread wheat genome is a hexaploid, resulting from the hybridization of the wild A. tauschii with a cultivated tetraploid wheat, Triticum turgidum.This spontaneous event occured about 8,000 years ago in the Fertile Crescent. (1987) measured ion concentrations in bread wheat and its putative ancestors including Aegilops and other Triticum species and concluded that A. tauschii (D genome) had similar K + /Na + ratios to that of hexaploid wheat, in contrast to low ratios in A. speltoides (B genome) and T. dicoccoides (AABB) and higher in T. monococcum (A genome). To assist the international bread wheat genome sequencing effort, a high quality draft of the genome of Aegilops tauschii, one of the three progenitors of bread wheat, will be produced.The large size and great complexity of the Ae.
