“…Nucleotide sequences of the nuclear ITS and chloroplast matK regions of the Astragalus species and all other information were available from the previous phylogenetic study dealing with Old and New World Astragalus species (Dizkirici et al, 2014). The ITS and matK sequence data of Oxytropis taken from the current study and those of Astragalus from the previous study were gathered to analyze together.…”

“…In the trees, only one representative was used to demonstrate a species since the sequences of replicate samples were identical. Moreover, sections of the genus Astragalus were simplified and indicated by schematic diagrams in the ITS tree because the evolutionary relationships among them were discussed in detail in a previous paper (Dizkirici et al, 2014).…”

“…Since phylogenetic relationships among Astragalus species based on ITS region were explained in detail in the previous study (Dizkirici et al, 2014), only relationships among the Oxytropis species are presented in depth here. Although relatively low genetic divergence among native Oxytropis species was present, the revealed phylogenetic relationships among them were meaningful.…”

“…In the literature, there are quite a number of valuable molecular studies (e.g., Wojciechowski et al, 1993;Sanderson and Wojciechowski, 1996;Dong et al, 2003b;, 2005Wojciechowski, 2005;Scherson et al, 2008;Kazemi et al, 2009;Dizkirici et al, 2014) indicating the phylogenetic relationships among Astragalus species, while there are few studies (Jorgensen et al, 2003;Archambault and Stromvik, 2012; dealing with the molecular phylogeny of the genus Oxytropis. There is no study dealing with native Oxytropis species although Turkey is one of the diversity centers for both taxa.…”

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.

Astragalus is the largest genus of seed plants; however, information on its reproductive biology and life history is widely scattered in the literature. About 96% of the species are perennials and 4% annuals; many are rare endemics. Astragalus species are obligate or facultative outcrossers, and inbreeding depression is higher in self-compatible (SC) than in self-incompatible (SI) species. The most frequent pollinators are Bombus, Osmia and Anthophora. On average, 48% of ovules produce seeds, and 40% of flowers produce fruits. Seed/ovule and fruit/flower ratios are lower in SC than in SI species. Predispersal insect seed predation ranges from 0 to 93%, and major predators are Acanthoscelides, Bruchophagus and Tychius. Seeds have physical dormancy and typically form a seed bank. C 3 is the only photosynthetic pathway in the genus. Population growth may be cyclic or noncyclic, and genetic diversity of a taxon may or may not be related to size of geographic range.
