Genetic Diversity and Relationships among Local Olive (Olea europeaea L.) Genotypes from Gaziantep Province and Notable Cultivars in Turkey, Based on SSR Markers

Olive and olive oil have a prominent place in the cultures of the countries within the Mediterranean basin including Turkey. The genetic relationships among 30 olive (Olea europaea L.) genotypes sampled from Gaziantep province in Turkey were examined using 10 simple sequence repeat (SSR) markers (DCA9, DCA11, DCA15, DCA18UDO4, UDO9, UDO11, UDO12, UDO22, UDO24). Also, three well known Turkish and one foreign olive cultivar were also included within the SSR analysis. The number of alleles per locus of the SSR markers ranged from 5 (DCA15, UDO9) to 14 (DCA9) (average 7.9), for a total of 79 alleles. Similarity coefficients were calculated on the basis of 79 amplified bands. A dendrogram was created according to the 10 SSR markers by the unweighted pair-group method. The banding patterns obtained from the SSR primers allowed all of the genotypes/cultivars to be distinguished. According to the dendrogram, the 33 olive genotypes and cultivars were clustered into five main clusters. The most closely related genotypes were 'Oguzeli 3' and 'Yavuzeli 1' with 0.80 similarity ratio. The most genetically divergent cultivars were 'Yavuzeli 6' and 'Kilis Yaglik' (0.30), 'Yavuzeli 6' and 'Saurani' (0.20), 'Nizip 7' and 'Yavuzeli 4' (0.15), 'Islahiye 5' and 'Nizip Yaglik' (0.10). In conclusion, SSR analysis can be an efficient method for olive genotypes and cultivar identification and can offer valuable informative data to identify olive genotypes and cultivars grown in Turkey

Molecular characterization of ancient olive genotypes from Hatay Province in Turkey

WOS: 000386907000014Turkey's average share of world olive production is between 7% and 10% and the country is the fourth biggest table olive and olive oil producer in the world. More than fifty olive cultivars have been commercialized in Turkey and there are numerous olive genotypes in different olive-growing regions in Turkey that differ from each other in terms of leaf, flower, and fruit characteristics. The aim of the present study was to identify the 40 most widely grown olive genotypes in Hatay Province in Turkey using microsatellite or simple sequence repeat (SSR) markers. Ten SSR loci were selected and used to identify olive genotypes/cultivars. The number of alleles per locus was found to be between 4 (UDO4 and DCA13) and 16 (DCA9), indicating high polymorphism among olive germplasms. We did not determine identical cultivars in SSR analysis. Samandag2 and Dortyol7 (0.85), Samandag7 and Saurani (0.75), Payas kalesi and Sari ulak (0.75), and Yayladag4 and Samandag3 (0.70) genotype pairs showed higher similarity while Yayladag1 and Samandag8 (0.15), Reyhanli1 and Yayladag6 (0.15), and Samandag8 and Hassa5 (0.15) were found to be the most genetically divergent genotypes

Genetic Diversity Among Historical Olive (Olea europaea L.) Genotypes from Southern Anatolia Based on SSR Markers

WOS: 000387577500008PubMed: 27424255Olive (Olea europaea) is an ancient and important crop in both olive oil production and table use. It is important to identify the genetic diversity of olive genetic resources for cultivar development and evaluation of olive germplasm. In the study, 14 microsatellite markers (UDO4, UDO8, UDO9, UDO11, UDO12, UDO22, UDO24, UDO26, UDO28, DCA9, DCA11, DCA13, DCA15, and DCA18) were used to assess the genetic variation on 76 olive (Olea europaea L.) genotypes from Mardin province together with 6 well-known Turkish and 4 well-known foreign reference cultivars. All microsatellite markers showed polymorphism and the number of alleles varied between 9 and 22, with an average of 14.57. The most informative loci were DCA 11 (22 alleles) and DCA 9 (21 alleles). Dendrogram based on genetic distances was constructed for the 86 olive genotypes/cultivars, which revealed the existence of different clusters. The high genetic similarity was evident between Bakirkire2 and Zinnar5 (0.74) genotypes, while the most genetically divergent genotypes were Gurmese5 and Yedikardes, ler2 (0.19). It was concluded that there was abundant SSR polymorphism in olive germplasm in southern Anatolia in Turkey and could be important for future breeding activities

Morphological and Pomological Properties and Fatty Acid Composition of Olive Genetic Resources in Şırnak Province

Ülkemiz Güneydoğu Anadolu Bölgesi'nde yer alan Şırnak ilindeki zeytin gen kaynaklarının oluşturduğu populasyon içerisinden üstün nitelikli olanları belirlemek amacıyla gerçekleştirilen çalışmada, 34 genotipten sürgün, yaprak ve meyve örnekleri alınmıştır. Belirlenen genotiplerde ağaç, meyve ve yaprak özellikleri ile toplam yağ ve yağ asitleri kompozisyonları incelenmiştir.

Does the Presence of Anterior Mandibular Teeth Increase the Incidence of Denture Stomatitis?

Purpose: To compare the frequency of denture stomatitis (DS) under maxillary complete dentures (CDs) in patients with opposing mandibular distal extension removable partial dentures (RPDs) and CDs. Materials and Methods: Participants included 365 maxillary CD wearers (241 women, mean age 70.5 +/- 13.2 years; 124 men, mean age 71.5 +/- 10.4 years) from 7 rest homes in Istanbul. A total of 268 had mandibular CDs; 97 had mandibular distal extension RPDs. Two independent, calibrated examiners performed oral examinations. Presence of maxillary denture-related stomatitis and the effect of risk factors on DS were evaluated and recorded. Results: The frequency of palatal DS (Newton I-III) was 45.1% (n = 121) in the mandibular CD group and 49.5% (n = 48) in the mandibular distal extension RPD group, a statistically insignificant difference (p= 0.4). Factors significantly associated with palatal DS were maxillary denture age (p= 0.02), reduced occlusal vertical dimension (p= 0.04), and nocturnal denture wear (p= 0.03). Conclusion: In this study, DS beneath maxillary CDs did not differ between mandibular distal extension RPD and CD wearers. The presence of mandibular anterior teeth did not influence the occurrence of palatal DS

The effect of mandibular anterior teeth on the hypermobile tissue in the anterior part of the maxilla

The absence of posterior occlusal contacts may result in increased anterior occlusal contacts and forces between natural mandibular dentition and artificial maxillary dentition. The impact of natural mandibular anterior teeth on the development of hypermobile tissues in the anterior part of the edentulous maxillary alveolar ridge was investigated in this study. The study group consisted of 410 patients with maxillary complete dentures and various mandibular dentitions from seven rest homes in Istanbul. The data; including hypermobile tissue in the anterior part of the maxilla, occlusal relationship, nocturnal wear, denture age, and duration of the maxillary full edentulism period were recorded. A chisquare test was performed to analyze the effects of following data: Existence of mandibular anterior teeth, poor adaptation of the dentures, nocturnal wear, types of occlusal contacts, and gender, on the resorption of the anterior part of the maxilla. To examine the effects of the presence of anterior mandibular teeth and early maxillary edentulism on bone resorption in the anterior part of the maxilla, a logistic regression analysis was performed. The results reveal that patients with edentulous maxilla and natural mandibular anterior teeth are approximately twice more likely to show risk of hypermobile tissue in the anterior part of the maxilla than are full edentulous patients. Further, edentulous periods exceeding 30 years in maxilla seem to increase this risk approximately 4 times. (C) 2011 Elsevier Ireland Ltd. All rights reserved
