In the present work, the phenolic compounds content and antioxidant activity in the skin, pulp, seed, cane and leaf of one international (Muscat) and five native (Hosseini, Ghara Shira, Agh Shani, Ghara Shani and Ghara Ghandome) grape cultivated in West Azerbaijan, Iran were investigated. Ghara Shani grape skin was found to contain the highest content of total phenolic and anthocyanin and cane of Ghara Shani contains the highest amount of flavonoid. A remarkable DPPH radical scavenging activity up to 95% and consequently, the lowest IC50 was found for skin of Ghara Shani. According to RP-HPLC experiments, the highest concentration of phenolic compounds was identified as catechin (945 mu g/g), epicatechin (482 mu g/g), gallic acid (319 mu g/g) and resveratrol (29.8 mu g/g) in skin of Ghara Shani, quercetin in cane of Ghara Shani (956 mu g/g), rutin in skin of Ghara Shira (298 mu g/g) and caffeic acid in cane of Ghara Shira (17.4 mu g/g).

Determination of esterase enzyme polymorphism in house fly (Musca domestica L.) populations in Turkey
TAŞKIN, VATAN; Taskin, Belgin Gocmen; KÜÇÜKAKYÜZ, KÖKSAL; Kence, Meral (2011-01-01)
The objective of this study was to determine esterase enzyme polymorphism in 16 natural Musca domestica L. populations from the Aegean and Mediterranean regions of Turkey by using the native polyacrylamide gel electrophoresis (PAGE) technique. The high level of genetic variation among populations and species make esterase enzymes an important tool for analyzing genetic differentiation and evolutionary relationships in insects. In the present study, 22 a-esterase bands were detected by using a-naphthylacetat...

Background: A total of 150 bread wheat genotypes representing 121 Indian and 29 Turkish origin were screened for nutrient concentrations and grain protein content. Elemental and grain protein composition were studied by Inductively Coupled Plasma-Atomic Emission Spectrophotometer and LECO analyser, respectively. The study was performed to determine the variability in nutrient concentrations present in the collected wheat genetic material from two countries. Results: Several fold variations among genotype...
Assessment of genetic variation of bread wheat varieties using microsatellite markers
Akkaya, Mahinur; Buyukunal-Bal, EB (2004-01-01)
The DNA fingerprinting profiles of 11 bread wheat cultivars, grown in Turkey, was obtained by using 19 highly polymorphic wheat microsatellites. Up to six randomly selected individuals from each of these cultivars were subjected to analysis. Estimated polymorphism information content (PIC) values among 65 individual genotypes for 19 loci were between 0.36 and 0.87 with an average value of 0.68. The numbers of observed alleles were between 2 and 9, with an average value of 5.42. These relationships were asse...
Assessment of genetic relationships in durum wheat cultivars using AFLP markers
Incirli, A; Akkaya, Mahinur (2001-06-01)
The genetic relationships were assessed for the first time in Turkish durum wheat cultivars using AFLP markers. In the analysis, 18 AFLP primer combinations resulted in a total of 189 polymorphic loci. All of the selective primers used are Eco and Mse primers with three nucleotide extentions on the 3' ends. The number of polymorphic markers per primer combination ranged from 4 to 24. The relationships, among nine winter and six spring type durum wheat cultivars, obtained with various algorithms are in accor...
Identification of differentially expressed transcripts from leaves of the boron tolerant plant Gypsophila perfoliata L.
Unver, Turgay; Bozkurt, Osman; Akkaya, Mahinur (Springer Science and Business Media LLC, 2008-08-01)
Very recently some of the species of Gypsophila genus collected from the boron rich soils in Turkey were shown to be remarkably tolerant to high levels of boron. A limited amount of boron is necessary for the normal development of plants; however, a high level of boron in soil is generally toxic. Nevertheless, the adaptability of plant species allows them to withstand the presence of extreme amounts of metal ion by various strategies. This study is conducted on highly boron tolerant Gypsophila perfoliata L....
