Master Thesis Characterization of Glycoalkaloid Content and Molecular Mapping in Eggplant(Izmir Institute of Technology, 2006) Kırsoy, Öyküm; Frary, Anne; Frary, Anne; 04.03. Department of Molecular Biology and Genetics; 04. Faculty of Science; 01. Izmir Institute of TechnologyIn this thesis, solamargine which is a known eggplant glycoalkaloid and has an important place for human health was characterized in eggplant. For characterization, two eggplant lines S.melongena MM738 and S.linnaeanum MM195 were used. Although, for identification and detection of glycoalkaloid concentration, many different methods have been utilized, for this thesis, high-performance liquid chromatography (HPLC) was used to analyze glycoalkaloid concentration in eggplant. In HPLC, spiking of samples was done using a solamargine standard and it was found that S. melongena had an undetectable level of solamargine while S. linnaeanum had between 17.6 and 33.4 mg (average 25.5 ± 11) solamargine per gram of freeze dried powder. In addition to characterization of glycoalkaloids in S.melongena MM738 and S.linnaeanum MM195, different types of molecular markers were surveyed for polymorphism in S.melongena MM738 and S.linnaeanum MM195 for mapping. A total of 47 polymorphic markers were then tested on the F2 population and located on the eggplant molecular genetic map.Master Thesis Proteomic Basis of Drought Tolerance in Chickpea(Izmir Institute of Technology, 2010) Şelale, Hatice; Şelale, Hatice; Frary, Anne; Frary, Anne; 04.03. Department of Molecular Biology and Genetics; 04. Faculty of Science; 01. Izmir Institute of TechnologyIn this study our aim was to identify differentially expressed proteins in root and leaf samples of the drought tolerant chickpea cultivar Gokce using proteomics approaches. For this aim we carried out 2D gel electrophoresis from total proteome extracts of root and leaf samples of Gokce cultivar from drought treated and control samples. In root 2D gels we obtained approximately 430 proteins; 14 of them were newly formed and 4 of them were disappeared in drought stress. Also we obtained 12 over-expressed protein and 4 down-regulated spot as a result of drought stress. In leaf 2D gels we obtained approximately 450 proteins 4 of them were newly formed spots, and 3 of them were disappeared in drought stress. For these samples we obtained 24 over-expressed proteins and 17 down-regulated proteins in drought stress. We identified differentially expressed proteins in MALDI-TOF/TOF mass spectrometer via peptide mass fingerprinting. Identified proteins are zinc finger (C2H2 type, AN1-like) family protein, pathogenesis-related family protein, STRS2 (STRESS RESPONSE SUPPRESSOR 2), 26S proteasome non-ATPase regulatory subunit 3, pentatricopeptide repeat-containing protein, RABB1C (ARABIDOPSIS RAB GTPASE HOMOLOG B1C); serine hydroxymethyltransferase, fiddlehead protein, aluminum-activated malate transporter, phloem protein 2-A8, ribosomal protein L30 family protein, N-rich protein with known function and we identified 14 hypothetical proteins with unknown function. Identified proteins are WRKY DNA-binding protein 6, myb family transcription factor, porin family protein, pentatricopeptide repeat (PPR) protein and transmembrane protein and 2 hypothetical proteins with unknown function.
