Genetic structure of anchovy populations was studied using genetic-biochemical markers. Anchovy samples collected between 1980 and 2006 from different Black Sea regions (off the Bulgarian, Turkish, Ukraine, and Georgian coasts) as well as from the Sea of Azov were analyzed. Three methods of electrophoresis were applied: starch gel electrophoresis, vertical polyacrylamide electrophoresis, and isoelectric focusing on thin polyacrylamide ampholine gel plates. On the base of long-term monitoring of allelic frequencies of the polymorphic non-specified esterases loci (EST-1* and EST-2*), wintering migration of Azov anchovy may have alternative routs along the western Black Sea coasts. Typical Azov anchovy winter together with the Black Sea anchovy form the mixed populations along the Ukrainian, Georgian, and Turkish Black Sea coasts. Azov anchovy was also registered along Bulgarian coast during the second part of May and July. The results allow supposing the north-western Black Sea as complementary spawning areas of Azov anchovy.

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...
Assignment of biological functions to specific plasmids in a local isolate of Rhizobium cicer Yıldız, Eda; Özcengiz, Gülay; İçgen, Bülent; Alaeddınoglu, Ng (Springer Science and Business Media LLC, 1999-01-01) The genetic basis of symbiosis, mucoid structure and melanin biosynthesis in a local isolate of Rhizobium cicer was investigated. The strain was avery effective symbiont and produced substantial amounts of exopolysaccharides and melanin. It harbored three high-molar-mass plasmids of 55, 80 and 130 kb, respectively. Thirty-one melanin production-negative (Mep(-)) derivatives were obtained through plasmid curing. The plasmid patterns of cured derivatives indicated that the loss of 55 and/or 80 kb plasmids was...
Development of PCR methods for detection and quantification of genetically modified maize Jabbari Farhoud, Houman; Gültekin, Güzin Candan; Department of Biotechnology (2010) This study describes development of methods for screening, identification and quantification of genetic modifications in maize samples. Totally 88 maize samples were collected randomly throughout Turkey in three years from 2006 to 2008 and were analyzed. Two maize samples that were detected as GM positive in previous studies were selected as positive controls. Following the DNA extraction by manual CTAB method, conventional PCR methods were employed for screening of genetic modifications in samples by detec...
The role of the cross pathway control protein in the stress response and adaptation of aspergillus species to antifungals Amarsaikhan, Nansalmaa; Ögel, Zümrüt Begüm; Bakır, Ufuk; Department of Biotechnology (2010) In this study, the adaptation and response of Aspergillus nidulans and Aspergillus fumigatus wild type and cpcA strains to antifungal compounds were studied using cultural, genetic and proteomic methods. CpcA is the fungal cross pathway control protein which may also have a role in the development of resistance to antifungal that has become a major problem in human and plant fungal diseases and many studies are devoted to address the drug resistance mechanisms. Cell adapts itself to stress when it is subje...
Estimation of phytoplankton biomass using HPLC pigment analysis in the southwestern Black Sea Ediger, D.; Soydemir, N.; Kıdeyş, Ahmet Erkan (2006-01-01) The phytoplankton population of the southwestern Black Sea in May 2001 was studied by taxonomic analysis using microscopic examination and by pigment analyses using high-performance liquid chromatography (HPLC). Pigment data, which identified phytoplankton assemblages dominated by dinoflagellates, diatoms and coccolithophores in May 2001, were compared to phytoplankton cell counts and biomass. There were significant (p < 0.002-0.01, r=0.56-0.67) relationships between the taxon-specific pigment concentration...
