UPGMA dendrograms of the relationships based on IRAP analysis of (A) accessions of Ae. tauschii subsp. tauschii var. tauschii; and (B) accessions of Ae. tauschii subsp. tauschii var. meyeri superimposed on their geographic origins; thick black lines show political boundaries; major hydrographic features are indicated in light grey. (C) A possible phylogeography of Ae. tauschii supported by the IRAP data. The species originates from the north of Iran and is distributed in two directions. The populations possessing the subsp. tauschii genepool are suggested to have expanded from the central Alborz Mountains and then distributed eastward and westward (direction 1); populations possessing the subsp. strangulata genepool are suggested to have been distributed along the Caspian Sea shore (direction 2).
