The genetic structure of Anatolian turkish population based on fifteen loci

The Effects of sex ratio in estimation of genetic differentiation in populus nigra populations Yelmen, Burak; Kaya, Zeki; Department of Biology (2017) Effective population size is an important concept in conservation biology. Biased sex ratio lowers effective population size, consequently causing loss of genetic variation. In this study, available microsatellite DNA marker data of 121 Populus nigra clones originated from 5 geographical regions were analyzed to evaluate genetic diversity of genders and to investigate possible effects of sex ratio on differentiation in these populations in Turkey. There was an abundance of identical genotypes in the dataset...
Association of the CYP2E1, FMO3,NQO1,GST,NOS3 genetic polymorphisms with ischemic stroke risk in Turkish population Özçelik, Aysun; Banerjee, Sreeparna; Çoruh, Nursen; Department of Biochemistry (2011) Stroke, a major cause of death and disability, is described as interruption or severe reduction of blood flow in cerebral arteries. Oxidative stress plays an important role in the pathogenesis of atherosclerosis and carotid atherosclerosis is a risk factor for stroke. Combination of multiple environmental and genetic risk factors is thought to increase susceptibility to the development of this disease. Therefore, investigation of the polymorphisms of drug metabolizing enzymes is of crucial importance to det...
Morphometric and genetic analyses on freshwater fish, Pseudophoxinus (Teleostei: Cyprinidae) populations in Turkey Altun, Ayhan; Kence, Aykut; Kence, Meral; Department of Biology (2017) With exceptional species richness and high level of endemism the Mediterranean region is recognized as one of the most important freshwater biodiversity hotspots in the world. One of the main temperate Mediterranean refugia is Anatolia with high biodiversity and strong genetic imprints. Complex patterns of population structure within the Mediterranean refugia are the results of the existence of fragmented distribution, dispersion process and gene flow occurred during range expansion in the interglacial peri...
The role of small heat shock proteins of the thermoacidophilic archaeon thermoplasma volcanium in the stress response Aygar, Sema; Kocabıyık, Semra; Department of Biological Sciences (2011) In this study, possible involvement of the small heat shock proteins (sHsps) from a thermoacidophilic archaeon, Thermoplasma (Tp) volcanium in the stress response was investigated. Our results showed that heterologous, high level expression of TVN0775/sHsp gene in E.coli increased its thermotolerance at 53°C for two hours. But, the second sHsp of the Tp. volcanium, TVN0984/sHsp was not effective in improvement of the thermal resistance of the mesophilic bacterium (i. e., E.coli). The expression of the TVN07...
Determination and comparison of genetic variation in honey bee (Apis mellifera L.) populations of Turkey by Random Amplified Polymorphic DNA and microsatellite analyses Ivgin Tunca, Rahşan; Kence, Meral; Department of Biology (2009) We analyzed a total of 760 worker bees, two samples per colony, 390 colonies in 26 provinces in Turkey to determine and compare the genetic variation of Turkish honey bee (Apis mellifera L.) populations using 10 primers for RAPD and 6 microsatellite loci. Mean gene diversity levels ranged from 0.035 (Sanlıurfa) to 0.175 (Antalya) for RAPD and 0.449 (Muğla) to 0.739 (Artvin) for microsatellite markers. Private band patterns and alleles, pairwise FST values support that the Anatolian honey bees belong to C li...
