The common bean (Phaseolus vulgaris L.) is the most consumed food legume in the world and is a major source of dietary protein, carbohydrates, and valuable micronutrients, especially in developing countries. Diversity Arrays Technology (DArTseq), based on genome reduction with restriction enzymes, provides a rapid, high-throughput, and cost-effective tool capable of generating thousands of genotyped single nucleotide polymorphisms (SNPs) for a genome-wide analysis of genetic diversity. In this study, we aimed to characterize common bean accessions using SNPs detected by a DArTseq approach. A total of 43,018 SNPs were identified from 173 common bean accessions, including Andean and Mesoamerican genotypes. After filtering raw and redundant data, a total of 16,366 SNPs were considered for further analyses. According to population structure analysis, the genotypes were roughly divided into 2 gene pools of Andean and Mesoamerican types. Pairwise fixation index (Fst) values were calculated to resolve the differentiation between populations. This study demonstrated that discovering SNPs from the whole genome is a potential resource for identifying naturally diverse accessions and also the information could be used in breeding programs to develop new common bean varieties.
- MakaleAçık Erişim2016Diversity and ecology of benthic algae in Karagöl Lake, Karagöl-Sahara National Park (Şavşat, Artvin, Turkey)
Akar, Bülent; Şahın, Bülent
Benthic algal flora of Karagöl Lake, its seasonal variation, and the physical and chemical parameters of the water were studied between October 2008 and September 2010. The algal flora consisted of 112 taxa belonging to the divisions Charophyta (41), Chlorophyta (33), Cyanobacteria (18), Euglenozoa (17), Miozoa (2), and Ochrophyta (1). Six desmid taxa found in this research are new records for the freshwater algal flora of Turkey. The qualitative dominance of benthic taxa typical of slightly alkaline and mesotrophic ecosystems was observed. The qualitative and seasonal variations in epipelic taxa analyzed were dependent on the physicochemical characteristics of the water. Water quality was analyzed on the basis of benthic taxa, which are bioindicators. The physicochemical properties of the water are suitable for the development of a rich algal flora (especially desmids). According to the benthic algal composition and indicator species, it is estimated that Karagöl Lake has mesotrophic lake characteristics. This is the first study of benthic algal flora of Karagöl Lake and marks a significant contribution to the knowledge of Karagöl-Sahara National Park’s aquatic biodiversity.

- MakaleAçık Erişim2015Optimization of electrical power transmission lines' routing using AHP, fuzzy AHP, and GIS
Eroʇlu, Hasan; Aydin, Musa
With the increase of people's need for energy, electrical energy transmission has become a very important issue as well as electrical power generation. One of the most important problems in energy transmission is finding the best route in a very complex study area. To date, many people from different disciplines have come together to find the best routes by manual methods like using paper maps and deciding which route is the least-cost path (LCP) to the destination point. Today it is known that, in engineering problems, and especially in path-finding or site-placing problems, the Geographic Information System (GIS) is the most powerful tool. On the other hand, as finding the best route is a very complicated problem and many criteria should be considered, including slope, landslide, road/railway/pipeline crossing, ice zones, distances to roads, national parks, archaeological areas, residential areas forests, and river crossings, multicriteria decision methods like the analytic hierarchy process (AHP) and fuzzy analytic hierarchy process (FAHP) should be used to make the most accurate decisions. In this study, the AHP and FAHP are used to weight criteria relevant to energy transmission line (ETL) routing. According to the criteria, digital maps of the sample study area are edited, weighted, converted to raster-based format, and gathered using the Environmental Systems Research Institute's ArcGIS Desktop 10 software. After generation of the weighted surface map, the LCP tool is used to find the best route. By selecting different start and end points in the sample study area, accuracy and performance of the best routes according to the LCP algorithm are assessed and some problems of the routes for ETL routing are presented. With this study, mistakes by manual methods will decrease in ETL routing and other routing problems.
- MakaleAçık Erişim2015Comparison of perioperative oxidative stress in endovascular and open repair of abdominal aortic aneurysm
Doğan, Orhan Veli; Menteşe, Ümit; Doğan, Süheyla; Usta, Sefer; Turan, İbrahim; Haliloğlu, Ergün; Karahan, Süleyman Caner
Background/aim: To investigate the differences in perioperative oxidative stress (OS) in abdominal aortic aneurysm (AAA) patients treated with either endovascular repair (EVAR) or open repair (OR).; Materials and methods: Twenty patients (11 OR, 9 EVAR) treated for AAA with no known malignant or inflammatory disease and an aneurysm diameter of over 5 cm and no rupture were included in the study. Blood samples were obtained preoperatively, during aortic occlusion, and 1 h and 24 h after reperfusion. Total antioxidant status (TAS), total oxidative stress (TOS), and malondialdehyde (MDA) levels were measured and oxidative stress index (OSI) was calculated.; Results: OSI at 1 h and 24 h after reperfusion was higher in the EVAR group (P = 0.004 and P = 0.002, respectively). TAS levels were higher (P = 0.001, P = 0,029). MDA levels showed no difference (P = 0.291, P = 0.076). TOS levels were lower 24 h after reperfusion in the EVAR group (P = 0.018). Conclusion: Markers of oxidative stress were lower in the EVAR group. This may be associated with advantages of EVAR. More studies are required for a clear-cut conclusion.
- MakaleAçık Erişim2015Genetic diversity and population structure of common bean (Phaseolus vulgaris L.) accessions through retrotransposon-based interprimer binding sites (iPBSs) markers
Nemli, Seda; Kianoosh, Tala; Tanyolaç, Muhammed Bahattin
The common bean (Phaseolus vulgaris L.) is an important crop throughout the world and is highly recommended for many developing countries due to its nutritional components. A retrotransposon-based DNA marker system, interprimer binding sites (iPBSs), developed from reverse transcriptase primer binding sites, was used to determine genetic diversity in common bean accessions. The genetic polymorphism and effectiveness of the marker system were evaluated. A total of 180 polymorphic bands were detected using 47 iPBS primers among 67 common bean accessions, with an average of 4 polymorphic fragments per primer. The genetic similarity between accessions was calculated using the software NTSYS-pc and ranged from 0.09 to 0.99. The average polymorphism information content value for the iPBS markers was 0.73. A model-based clustering method classified the common bean accessions into 4 populations using STRUCTURE software. The results indicated that the iPBS marker method can successfully determine the genetic diversity level in common bean accessions.
- MakaleAçık Erişim2014Is the combined use of insulin resistance indices, Including adipokines, more reliable in metabolic syndrome?
Kural, Birgül; Değer, Orhan; Erem, Cihangir; Balaban Yücesan, Fulya; Aliyazicioğlu, Rezzan; Barlak, Yaşam
Background/aim: To determine the levels of adipokines (leptin, adiponectin, resistin, and visfatin) and the indices of insulin sensitivity/ resistance, and to examine the relationship among them in patients with metabolic syndrome (MetS).; Materials and methods: The study groups included 45 subjects with MetS (31 women/14 men), and 45 sex- and age-matched non-MetS healthy volunteers (31 women/14 men). The levels of adipokines were determined by enzyme-linked immunosorbent assay.; Results: The levels of leptin and visfatin were significantly higher in the MetS than in the non-MetS subjects (P < 0.01). There was no difference in adiponectin levels in subjects with and without MetS (P = 0.052). Similarly, resistin did not show any statistically significant difference. A statistically significant positive correlation of leptin with insulin levels was observed, while negative correlations of visfatin levels with age, and resistin levels with the ratio of adiponectin to leptin, were found in the MetS (P < 0.05). The combination of adipokines, insulin resistance-sensitivity parameters, and MetS criteria parameters gave more signifcant differences than a single parameter.; Conclusion: Since the parameters mentioned above might affect, interact with, and/or interfere with each other, the combinations of these parameters might give more reliable results to evaluate the insulin resistance/sensitivity in MetS patients.

Yildirim, Mustafa; Gezginç, Hasan; Paksoy, Ali Haydar
In this study, the combined ability effects and heterosis were determined for number of days to anthesis (AT), plant height (PH), fertile tillers plant-1 (FT), spike length (SL), spikelets spike-1 (SS) and grains spike-1 (GS), 1000-kernel weight (TW), and grain yield plant-1 (GY) of 4 triticale genotypes [Karma (G1), Presto (G2), Ayşehanım (G3), and Mehmetbey (G4)] and their 6 F1 offspring. The mean squares of general combining ability (GCA) and specific combining ability (SCA) were statistically significant for all traits. According to the GCA/SCA, additive gene effects were found for all traits. According to the desired values for traits on the basis of GCA and SCA, parents G1 were good general combiners for 3 traits, G3 for 6, and G4 for 6. Crosses G1 × G2 were good specific combiners for 3 traits, G1 × G3 for 3, G1 × G4 for 3, G2 × G3 for 5, G2 × G4 for 6, and G3 × G4 for 4. Heterosis and heterobeltiosis were -16.78% and -25.71% for AT, -1.66% and -11.02% for PH, 34.25% and 9.87% for FT, 14.62% and 11.44% for SL, 8.09% and 3.87% for SS, 4.57% and 0.91% for GS, 9.67% and 6.13% for TW, and 30.36% and 9.11% for GY, respectively. The results revealed that G2 × G3 and G2 × G4 combinations could be recommended for improved yield of triticale.
- MakaleAçık Erişim2011Stability properties of certain durum wheat genotypes for major quality characteristics; [Makarnalik buĝday genotiplerinin temel kalite kriterleri bakimindan stabilite özellikleri]
Sakin, Mehmet Ali; Düzdemir, Oral; Sayaslan, Abdulvahit; Yüksel, Ferhat
Many ecological regions of Turkey are suitable for the production of durum wheat, and therefore the yield and quality of this wheat should be improved. In this study, stability properties associated with the pasta quality of 25 durum wheat (Triticum durum Desf.) genotypes grown in 3 dif erent locations (Tokat-Kazova, Diyarbaki{dotless}r, and Sivas-Ulaş) for 2 years (2005-2006, 2006-2007) were investigated. Durum wheat genotypes were composed of 12 registered varieties and 13 advanced experimental lines. Field trials were conducted in a randomized complete block design with 3 replications. Protein content, gluten index, sedimentation and specif c sedimentation volumes, yellow pigment content, and lipoxygenase activity of the durum wheats were measured as major quality characteristics. T e regression coef cient (bi) and mean square of deviation from regression (S2 d) were employed as the stability parameters. Genotypes, growing environments, and their interactions were found to be statistically signif cant (P < 0.01) for all investigated quality characteristics. No cultivars were determined to be simultaneously stable for all of the quality characteristics, yet some of the genotypes prevailed for certain quality characteristics. T e genotypes with the same origin took part in the same group as judged by the cluster analysis. Of the advanced experimental durum wheat lines, Line - 1, Line - 7, Line - 20, and Gdem - 12, which displayed better quality characteristics than the overall means, can be used as breeding materials. Of the registered varieties, Aydin - 93, Çeşit - 1252, and Gidara were determined to be stable by both parameters in certain quality characteristics.
