(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). tauschii accessions with diverse geograph‑ ical backgrounds were investigated for their resistance to infection by the leaf rust fungi Puccinia triticina. comosa (MM genome), and Ae. Aegilops tauschii. Here, we generated a chromosome-scale, high-quality reference genome of Aegilops tauschii, the donor of the wheat D genome, in which 92.5% sequences have been anchored to chromosomes.
