Aegilops tauschii, the Tausch's goatgrass or rough-spike hard grass, is an annual grass species.[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]

Taxonomy

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.[4]

Genome

Zimin et al., 2016 provides a genome assembly.[5]

The Lr42 nucleotide-binding site leucine-rich repeat (NLR) is a resistance gene used in hexaploid wheat but originating in this species.[6] Lr42 confers all-stage resistance to leaf rust.[6] Lin et al., 2022 localize Lr42 to AET1Gv20040300 by cloning and sequence- and functional-analyses.[6]

Subspecies

The following subspecies are accepted:[2]

  • Aegilops tauschii subsp. strangulata (Eig) Tzvelev – western part of range
  • Aegilops tauschii subsp. tauschii
