Article Citation - WoS: 3Citation - Scopus: 3Structural Vulnerability of Ancient Dry Masonry Towers Under Lateral Loading(Elsevier, 2020) Gençer, Funda; Hamamcıoğlu Turan, Mine; Turan, Mine; Aktaş, Engin; Aktaş, EnginUnderstanding how the original characteristics contribute to the structural behaviour of antique structures should be the initial stage of planning for conservation work. This study aims to identify the structural behaviour of dry masonry towers under lateral loadings, so that the decision-making process when determining their restoration can be adequately supported. Dry masonry towers in ancient Caria, Pamphylia, and Cilicia Regions are examined. Each of these three areas have very different seismic characteristics. A hypothetical testing process was designed by combining different characteristics from each of the towers. As a result, the characteristics affecting the structural resistance were determined as; the staggering ratio, the stone depth, the ratio between block length and height, the proportional relationship between height and length, the area, number and position of openings, and the distribution of header stones. These characteristics all interact together to determine the failure mechanism; so, understanding this interaction is critical when considering conservation. © 2020 Elsevier LtdArticle Citation - WoS: 12Citation - Scopus: 17Pyramiding Multiple Genes for Resistance To Pvy, Tswv and Pmmov in Pepper Using Molecular Markers(Verlag Eugen Ulmer, 2014) Özkaynak, E.; Devran, Z.; Kahveci, E.; Doğanlar, Sami; Başköylü, B.; Doğan, F.; İşleyen, M.; Yüksel, A.; Yüksel, M.Pepper (Capsicum annuum L.) is one of the most important vegetables cultivated worldwide. Many pests and pathogens cause economic yield losses in pepper. Potato virus Y (PVY), Tomato spotted wilt virus (TSWV) and Pepper mild mottle virus (PMMoV) are considered among the most destructive viruses affecting pepper in the world. Because chemical treatments have limited success for managing PVY, TSWV and PMMoV, resistant varieties are considered to be the most effective means of controlling these viruses. In this study, resistance genes to these viruses were successfully transferred to the superior sweet Charleston pepper line 'Y-CAR' using molecular markers and biological assays. As a result, a new line which is resistant to PVY, TSWV and PMMoV was developed. The results also showed the applicability of a pyramiding strategy for breeding multiple virus resistance in pepper. © Verlag Eugen Ulmer KG, Stuttgart.Article Citation - Scopus: 2Identification of Potato Y Potyvirus (pvy°) Resistance in Wild and Cultivated Tomatoes(Türkiye Klinikleri Journal of Medical Sciences, 2009) Çelebi Toprak, Fevziye; Barutçu, Eminur; Frary, Anne; Doğanlar, SamiPotato Y potyvirus (PVY) is an important plant pathogen worldwide that infects and causes yield losses in the family Solanaceae including potato (Solarium tuberosum), pepper (Capsicum spp.), tomato (S. lycopersicum), and tobacco (Nicotiana tabacum). In this study, 20 different tomato accessions representing 6 different species were mechanically inoculated with PVY°. The plants were scored visually for symptoms and then tested for presence of the virus 2-4 weeks after inoculation by ELISA. The results were variable. Most wild species of tomato sustained PVY° replication in inoculated leaves. Some of the wild species showed an immune response, while some became systemically infected. Inoculation and analysis of F2 populations suggested that the resistance is controlled by a single recessive gene in different wild species.
