[1] It is native to Crimea, the Caucasus region, western and Central Asia, Afghanistan, Pakistan, the western Himalaya, and parts of China, and has been introduced to other locales, including California.

[2] Aegilops tauschii is part of the tribe Triticeae, along with wheat.

It is a diploid (2n=2x=14, DD) goatgrass species[3] which has contributed the D genome to common wheat.

[5] The Lr42 nucleotide-binding site leucine-rich repeat (NLR) is a resistance gene used in hexaploid wheat but originating in this species.

[6] Lin et al., 2022 localize Lr42 to AET1Gv20040300 by cloning and sequence- and functional-analyses.
