Genome
Zimin et al., 2016 provides a genome assembly.
The Lr42 nucleotide-binding site leucine-rich repeat (NLR) is a resistance gene used in hexaploid wheat but originating in this species. Lr42 confers all-stage resistance to leaf rust. Lin et al., 2022 localize Lr42 to AET1Gv20040300 by cloning and sequence- and functional-analyses.
Subspecies
The following subspecies are accepted:
- Aegilops tauschii subsp. strangulata (Eig) Tzvelev – western part of range
- Aegilops tauschii subsp. tauschii
