“…Furthermore, the obtained results are consistent with the previous studies of chloroplast or nuclear DNA sequences (e.g. Blattner 2009, Naghavi et al 2013. Within each of the analyzed loci the tetraploid H. murinum specimens from Central Europe were the same as their probable progenitor-the diploid H. glaucum.…”

This study presents a phylogenetic analysis of the selected representatives of the Triticeae tribe and the assessment of possibilities of species identification on the basis of sequence variation in the three regions from the chloroplast DNA (matK, rbcL and trnH-psbA). The analysis included diploid and polyploid species of the following genomic compositions: E b , E e , H, I, Ns, St, Ta, Xu, NsXm, XoXr, XuXu, E b E e , E b E b E e , E b E e St, StH, StStH. The obtained matK and rbcL sequences revealed three well-supported clades: (1) Elymus, Lopophyrum, Pseudoroegneria, Thinopyrum (genomes E b , E e , St, StH, E b E e , E b E b E e , E b E e St, StStH); (2) Leymus, Hordelymus, Psathyrostachys (genomes Ns, NsXm, XoXr); (3) Hordeum (genomes H, I, Xu). This results support the view that the analyzed Elymus species (E. caninus, E. repens) acquired the Pseudoroegneria St genome maternally. They also indicate that Hordelymus europaeus carries the Ns genome from Psathyrostachys and point at the maternal origin of this component. Moreover, the presented results confirm the contribution of Psathyrostachys in the origin of Leymus as well as indicate the maternal character of this input. Differentiation observed within the Hordeum clade aligns with the alleged genome composition of the analyzed species. The DNA barcoding potential of the analyzed sequences was low. Nevertheless, several informative polymorphisms were found like e.g. the matK substitution specific for Thinopyrum bessarabicum, the trnH-psbA substitution differentiating Leymus arenarius from Psathyrostachys juncea and the group of speciesspecific deletions within trnH-psbA. In the DNA barcoding context we have also demonstrated negative importance of the high frequency cpDNA inversion leading to intraspecific variation.

“…Moreover, their analysis separated the three studied genomes of the Hordeum clade, namely, I (in diploid H. bogdani), H (in diploid H. bulbosum) and Xu (in diploid H. murinum). These results are consistent with previous studies of chloroplast and nuclear DNA sequences (e.g., Blattner 2009;Naghavi et al 2013).…”

Elymus purpuraristatus and Roegneria calcicola are perennial species of wheatgrass in Triticeae (Poaceae), treated as members of different genera on the basis of morphological characteristics. However, their genomic constitution is still unknown and their taxonomic status remains disputed. To identify their genomic constitution, we performed chromosome pairing analysis, genomic in situ hybridization and phylogenetic analyses on E. purpuraristatus and R. calcicola. The meiotic pairing results for the artificial hybrids of E. wawawaiensis (StH) × E. purpuraristatus, E. purpuraristatus × Campeiostachys dahurica var. tangutorum (StYH) and R. calcicola × C. kamoji (StYH) suggested that E. purpuraristatus and R. calcicola are allohexaploid with the St, Y and H genomes. The genomic in situ hybridization results of E. purpuraristatus and R. calcicola confirmed that they possess two sets of the H genome and two sets of the StY genome. Phylogenetic analyses suggested that Acc1 and DMC1 sequences from E. purpuraristatus and R. calcicola grouped with the St genome clade, Y genome clade and H genome clade, respectively. In summary, cytological and phylogenetic results indicated that the genome formula of E. purpuraristatus and R. calcicola is StStYYHH. According to the genomic system of classification in Triticeae, E. purpuraristatus and R. calcicola should be classified in Campeiostachys as C. purpuraristata and C. calcicola, respectively.
