Oxytropis and Astragalus represent one of the largest angiosperm genera complexes. Although phylogenetic studies of this complex exist, the evolutionary relationships among Astragalus and Oxytropis species sharing similar habitats in the Old World have not been studied in detail. The phylogenetic relationships among 13 Oxytropis and 56 Astragalus species native to Turkey were inferred from nucleotide sequence variations in the nuclear ribosomal internal transcribed spacer (ITS) and chloroplast maturase-like protein (matK) gene regions. In addition to our samples, 36 Oxytropis ITS and 6 Oxytropis matK sequences were retrieved from GenBank and included in the analysis. Phylogenies derived from a maximum likelihood analysis of the sequences indicated that Oxytropis and Astragalus genera are more likely monophyletic. However, the results suggest that New World Oxytropis species did not evolve by a single adaptive radiation in the genus, but rather from different Old World lineages. The genetic divergence between genera was less when the matK region was analyzed. Although the Oxytropis species did not show high genetic diversity, one subcluster of the genus was always distinctly separated in both trees. This subcluster was formed by the species Oxytropis engizekensis Duman & Vural and O. persica Boiss., which are also regarded as synonyms in regard to several morphological characters of the genus.

Phylogenetic relationships of Elymus L. and related genera (Poaceae) based on the nuclear ribosomal internal transcribed spacer sequences Dizkirici, Ayten; KAYA, ZEKİ; Cabi, Evren; Doğan, Musa (2010-01-01) To help in the clarification of the taxonomic status of Elymus L and related genera Agropyron Gaertn Leymus Hochst Hordelymus (Jess) Harz and Brachypodium P Beauv, the sequence diversity in the internal transcribed spacer (ITS) region of nuclear ribosomal DNA was studied ITS data of 64 Triticeae accessions including 40 Elymus 12 Agropyron 7 Leymus and 4 Hordelymus and 1 Brachypodium as an out group were analysed The molecular diversity statistics Indicated that the most diverse genus is Elymus among the stu...
MOLECULAR PHYLOGENY OF SECTION DROSANTHE (SPACH) ENDL. (HYPERICUM L.)INFERRED FROM CHLOROPLAST GENOME Dogan, Gulden; Yılmaz, Aslı; Bagci, Eyup; Kaya, Zeki (2017-12-01) The phylogenetic relationships of Drosanthe section of Hypericum genus (Hypericaceae) were analyzed by using non-coding chloroplast DNA region (trnL 3'-trnF) for 58 individuals. The section is represented by 23 taxa and nine of which are endemic to Turkey. The chloroplast phylogeny suggested that the members of this section belonged to a polyphyletic group, which imply at least two independent origins. The individuals of this section clearly formed two main clades. One clade included all members of this sec...
Phylogenetic relationships among native Oxytropis species in Turkey using the trnL intron, trnL-F IGS, and trnV intron cpDNA regions Tekpinar, Ayten; KARAMAN ERKUL, SEHER; AYTAÇ, ZEKİ; Kaya, Zeki (2016-01-01) We tested the phylogenetic utility of three chloroplast DNA loci, i.e. the trnL((UAA)) intron,trnL((UAA))-F-(GAA) intergenic spacer (IGS), and trnV((UAC)) intron, across thirteen native Oxytropis species. Our objective was to determine whether any of these chloroplast DNA markers could be beneficial to figure out phylogenetic relationships among Oxytropis species. To increase the interspecific sampling, nine sequences of the trnL intron and trnL-F regions were retrieved from GenBank and included in the anal...
Phylogenetic relationships of Elymus L. and related genera (Poaceae) based on the nuclear ribosomal internal transcribed spacer sequences Dizkirici, Ayten; Kaya, Zeki; Cabi, Evren; Doğan, Musa (2010-11-23) To help in the clarification of the taxonomic status of Elymus L. and related genera Agropyron Gaertn., Leymus Hochst., Hordelymus (Jess.) Harz, and Brachypodium P.Beauv., the sequence diversity in the internal transcribed spacer (ITS) region of nuclear ribosomal DNA was studied. ITS data of 64 Triticeae accessions including 40 Elymus, 12 Agropyron, 7 Leymus, and 4 Hordelymus, and 1 Brachypodium as an out-group were analysed. The molecular diversity statistics indicated that the most diverse genus is Elymus...
Taxonomic Importance of Seed Morphology in Allium (Amaryllidaceae) CELEP, FERHAT; KOYUNCU, MEHMET; Fritsch, Reinhard M.; KAHRAMAN, AHMET; Doğan, Musa (2012-10-01) Allium is one of the largest monocotyledonous genera. Southwest to Central Asia is the major center of diversity for the genus. In the present study, seeds of 62 Allium taxa from Turkey classified in subg. Allium (sect. Allium, sect. Brevispatha, sect. Codonoprasum and sect. Multicaule), subg. Amerallium (sect. Molium), subg. Melanocommyum (sect. Acanthoprason and sect. Melanocrommyum), and subg. Polyprason (sect. Falcatifolio and sect. Scorodon) were examined using light and scanning electron microscopy to...
