Article Citation - WoS: 3Citation - Scopus: 3Gras-Di Snp-Based Molecular Characterization and Fingerprinting of a Turkish Corylus Avellana Core Set Provide Insights Into the Cultivation and Breeding of Hazelnut in Turkey(Springer, 2023) Yanar, Ertuğrul Gazi; Doğanlar, Sami; Frary, AnneHazelnut (Corylus avellana L.) is an economically and socially important product for Turkey, the country that leads global production of this crop. The preservation of Turkish hazelnut genetic diversity and informed breeding of new cultivars are crucial for maintaining quality and crop yield stability. In this study, genotyping by random amplicon sequencing (GRAS-Di) was used to identify single-nucleotide polymorphisms (SNPs) in a panel of 96 individuals representing the Turkish national hazelnut collection. The resulting 7609 high-quality SNPs were physically mapped to the Tombul cultivar reference genome and used for population structure and diversity analyses. These analyses revealed that cultivars are not less diverse than wild accessions and that 44% of the panel had admixed ancestry. The results also indicated that recently released Turkish cultivars are highly similar to each other, suggesting that diversity analysis is an important tool that should be employed to prevent future genetic bottlenecks in this crop. A minimal marker algorithm was used to select a set of seven SNP markers that were capable of differentiating the panel accessions. These fingerprinting markers should be useful for the propagation of true-to-type elite cultivars that can be used to renew Turkey's aging hazelnut orchards.Other Macromol. Mater. Eng. 7/2016(Wiley, 2016) Isık, Tuğba; Horzum Polat, Nesrin; Yıldız, Ümit Hakan; Liedberg, Bo; Demir, Mustafa MuammerAn easy-to-use test platform toward the rapid diagnosis of many life-threating diseases was developed. DNA was isolated from the mixture of BSA+DNA using fibrous commodity polystyrene, which was extremely cheap and can be readily electrospun under ambient conditions. Surface modification with Au nanoparticles improved the performance of the fibrous membrane.Article Citation - WoS: 6Citation - Scopus: 7Utilization of Electrospun Polystyrene Membranes as a Preliminary Step for Rapid Diagnosis(John Wiley and Sons Inc., 2016) Işık, Tuğba; Horzum, Nesrin; Yıldız, Ümit Hakan; Liedberg, Bo; Demir, Mustafa MuammerRecent advances in clinical practice drive deoxyribonucleic acid (DNA) as an important class of biomarker. Monitoring the change in their concentration suggests the initiation and/or progression of various disorders. However, low quantity of DNA biomarkers in body fluids requires a delicate isolation methodology that provides efficient separation and easy handling. This study describes a newer-generation separation technology relying on electrospun fibers of sub-micrometer diameter of a commodity polymer for DNA biomarkers in simulative serum. Fibrous polystyrene membranes are prepared by electrospinning and they are subjected to post-modification with Au. The composite membranes may provide a convenient environment for the removal of bovine serum albumin (BSA) from BSA and DNA mixtures. The eluent can be used as an efficient tool for detection of DNA biomarkers associated with diagnosis of numerous life-threatening diseases.
