In this study, Jurinea species native in Turkey were collected from different localities in Anatolia and DNA was isolated from the collected samples, using a commercial plant DNA extraction kit (Nucleon phytopure). Inter Simple Sequence Repeat (ISSR) was the fingerprinting method preferred due to its high level of reliability and consistency as compared with the Randomly Amplified Polymorphic DNA (RAPD). The data were analyzed with NTSYS-pc 2.1. The phytogeographical distribution of Jurinea was found to be closely related to the Anatolian Diagonal. Based on the Diagonal, two major taxonomic groups emerged, from which J. kileae was clearly separated both morphologically and phylogenetically.Öğe Phylogenetic relationships between Malcolmia, Strigosella, Zuvanda, and some closely related genera (Brassicaceae) from Turkey revealed by inter-simple sequence repeat amplification(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2011) Dogan, Bekir; Unal, Murat; Ozgokce, Fevzi; Martin, Esra; Kaya, AylaThe genus Malcolmia W.T.Aiton is taxonomically problematic, and some of its species have recently been transferred to the genera Strigosella Boiss. and Zuvanda Dvorak. Three species of this genus are native to Turkey. The revision studies based on molecular data, which were collected in the past few years, display the phylogenetic relations and the systematic positions of the taxa more reliably and apparently. Thus taxonomic problems of species are resolved through DNA-based molecular analyses, which are not affected by environmental factors compared to phenotypic studies. In the present study, the amplifications of the DNA fragments were carried out using ISSR primers, and the phylogenetic relationship among the taxa was revealed through a dendrogram produced as the outcome of the NTSYSpc 2.1 software. The infrageneric and intergeneric phylogenetic relationships among Malcolmia and other related genera are determined. A very close relationship was determined between Malcolmia chin and M. flexuosa. Strigosella and Zuvanda species were determined to be phylogenetically different from these 2 species. The phylogenetic relationships among the Malcolmia, Strigosella, Zuvanda, Leptaleum DC., Neotorularia Hedge & J.Leonard, and Sisymbrium L. taxa were investigated. The phylogenetic separation of Malcolmia, Strigosella, Zuvanda Leptaleum, Neotorularia, and Sisymbrium genera and their specimens constituted separate clades on the dendrogram.Öğe Psephellus vanensis (Asteraceae), a new species from east Turkey(PENSOFT PUBL, 2015) Dogan, Bekir; Behcet, Lutfi; Duran, Ahmet; Avlamaz, DavutA new species, Psephellus vanensis A.Duran, Behcet & B.Dogan (Asteraceae) from Anatolia, Turkey, is described and illustrated.

It is challenging to differentiate the genera based on morphological characters alone. Revision studies performed on the basis of molecular data obtained from studies conducted in recent years have made the phylogenetic relationships and systematic positions of the taxa more apparent and reliable. In this study, Klasea, Serratula, Jurinea and Centaurea species native to Turkey, were collected from different localities of Anatolia and DNA was isolated from the collected samples. The data were analyzed ordination analyses including UPGMA and PCA using NTSYSpc 2.1. The infrageneric and intergeneric phylogenetic relationships between Klasea and other related genera were also characterized. The Klasea species were grouped into three clusters. It was determined that taxa Klasea kotschyi and K. hakkiarica are separate but closely related. Moreover, it was observed that the Klasea lasiocephala a separate group within the genera. Clearly the genera Klasea, Serratula, Jurinea and Centaurea are phylogenetically differentiated on the dendogram.Öğe Study of phylogenetic relationship of Turkish species of Matthiola (Brassicaceae) based on ISSR amplification(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2016) Dogan, Bekir; Celik, Mustafa; Unal, Murat; Sefali, Abdurrahman; Martin, Esra; Kaya, AylaMatthiola W.T. Aiton is a taxonomically complex genus in which there are many problems, mostly with Matthiola longipetala and M. odoratissima. Matthiola species native to Turkey were collected from various locations in Anatolia, and their DNA was isolated. Revision studies performed on the basis of molecular data obtained from studies conducted in recent years have made the phylogenetic relationships and systematic positions of the taxa more apparent and reliable. Consequently, the remaining taxonomic problems among the species have been resolved through the use of DNA-based molecular analysis methods, which, unlike phenotype studies, are not affected by environmental factors. The inter-simple sequence repeat (ISSR) fingerprinting method was used in the study because its properties were considered to be more reliable and consistent than those of the randomly amplified polymorphic DNA method. DNA fragments were amplified through the use of ISSR primers. The phylogenetic relationships among the taxa were represented on a dendrogram constructed through means of NTSYSpc 2.02 software. The infrageneric and intergeneric phylogenetic relationships between Matthiola and other related genera were also characterized. It was determined that the taxa Matthiola odoratissima and M. ovatifolia are separate but closely related. Moreover, it was observed that the Matthiola longipetala complex forms a separate group within the genera. Clearly, the genera Matthiola, Sterigmostemum, Strigosella, Malcolmia, and Chorispora are phylogenetically differentiated on the dendrogram.Öğe Tragopogon anatolicus (Asteraceae), a new species from east Turkey(MAGNOLIA PRESS, 2014) Dogan, Bekir; Duran, Ahmet; Gultepe, Mutlu; Ozturk, Meryem; Coskuncelebi, KamilThe new species, Tragopogon anatolicus A. Duran, B. Dogan & Coskunc sp. nov. (Asteraceae) is described and illustrated from Cilo Mt. (Hakkari), south-east Anatolia, Turkey.
