A few disjunct populations of K. ceratoides subsp. ceratoides are found in Anatolia, Europe and North Africa to the west of its otherwise continuous Eurasian distribution. To understand the evolutionary history of this characteristic steppe and semi-desert plant, we analysed its phylogeny and biogeography. We sequenced several loci including ITS, ETS and the chloroplast intergenic spacer regions atpB-rbcL, rpl32-trnL and trnL-trnF to establish a time-calibrated phylogeny and reconstruct intraspecific relationships. Furthermore, we identified the ploidy level of individuals. While diploid, tetraploid and hexaploid individuals have been reported in the literature, we were only able to find diploids and tetraploids. The diploids were found in the east of Mongolia, Kazakhstan, Kyrgyzstan, Russia and the USA. The tetraploids were located in the west of Mongolia, Kazakhstan, Tajikistan, Russia, and Europe. Populations were uniformly di- or tetraploid. Our results indicate that the species may have spread from the area of Mongolia, northern China and Middle Asia (i.e., the Altai Mountains region) in two opposite directions – on the one hand, diploids migrated to the east, to eastern Asia and North America, and on the other hand diploids and tetraploids migrated to the west, to western Asia and Europe. Fossil-calibrated gene trees were used to estimate the age of the species. Diversification within the species is probably of Pleistocene age. Our dated analysis indicates that the first split among extant lineages of the species took place in the Early Pleistocene (Gelasian). The spread of the main lineages is likely related to major phases of steppe and semi-desert expansions during glacial periods of the Pleistocene. 000086479 536__ $$9info:eu-repo/grantAgreement/ES/DGA/A01 000086479 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000086479 590__ $$a2.088$$b2020 000086479 591__ $$aPLANT SCIENCES$$b111 / 235 = 0.472$$c2020$$dQ2$$eT2 000086479 591__ $$aECOLOGY$$b104 / 166 = 0.627$$c2020$$dQ3$$eT2 000086479 592__ $$a0.549$$b2020 000086479 593__ $$aEcology$$c2020$$dQ2 000086479 593__ $$aPlant Science$$c2020$$dQ2 000086479 593__ $$aEcology, Evolution, Behavior and Systematics$$c2020$$dQ2 000086479 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000086479 700__ $$0(orcid)0000-0002-8731-1009$$aPérez-Collazos, Ernesto$$uUniversidad de Zaragoza 000086479 700__ $$aTremetsberger, Karin 000086479 700__ $$aCarine, Mark 000086479 700__ $$0(orcid)0000-0001-7793-5259$$aCatalán, Pilar$$uUniversidad de Zaragoza 000086479 700__ $$aBernhardt, Karl-Georg 000086479 7102_ $$15011$$2063$$aUniversidad de Zaragoza$$bDpto.
