Determination and comparison of genetic variation in honey bee (Apis mellifera L.) populations of Turkey by Random Amplified Polymorphic DNA and microsatellite analyses

Ivgin Tunca, Rahşan
We analyzed a total of 760 worker bees, two samples per colony, 390 colonies in 26 provinces in Turkey to determine and compare the genetic variation of Turkish honey bee (Apis mellifera L.) populations using 10 primers for RAPD and 6 microsatellite loci. Mean gene diversity levels ranged from 0.035 (Sanlıurfa) to 0.175 (Antalya) for RAPD and 0.449 (Muğla) to 0.739 (Artvin) for microsatellite markers. Private band patterns and alleles, pairwise FST values support that the Anatolian honey bees belong to C lineage except for Hatay and Sanlıurfa populations illustrated from previous findings of mitochondrial DNA studies. Genetic differentiation (GST) from RAPD data ranged from 0.060 (Bilecik and Muğla) to 0.395 (Gökçeada and Sanlıurfa). The genetic diversity (FST) for microsatellites ranged from -0.068 (Gökçeada and Đzmir) to 0.347 (Konya and Muğla). The results of the present research are in agreement to that of previous study in Turkish honey bee populations which used different microsatellite loci. That is the genetic variation was the highest in African, the lowest in European and intermediate in the Mediterranean honey bee populations. The data presented here indicate that in spite of extensive migratory beekeeping, there is still a large genetic differentiation among honey bee populations. These results should be considered in establishment of conservation plans particularly in moving of colonies between regions. The most importantly introduction of bees with foreign origin and distribution queen bees from one center to all over the country which will homogenize the gene pool of the populations should be prevented


Morphometric, mtdna and microsatellite analysis in honeybee populations (apis mellifera L.) of north and northwest İran
Farhoud, Houman Jabbari; Kence, Meral; Department of Biotechnology (2004)
Morphometric measurements, mitochondrial DNA analyses and 5 microsatellite loci were used to investigate variation in the honeybee populations of Iran and comparing it with the Turkish populations. Five honeybee populations were sampled from North and west north of Iran. In morphometric aspect of the study 23 characters were measured from left forewings and hindlegs of honey bee samples. The data were analysed by multivariate statistical analyses. By using mtDNA analyses length polymorphism of the intergeni...
Screening for genetically modified tomatoes & tomato seeds and identification of CRY1AC and SAM-K specific modifications using gene and construct specific PCR
Uçkun, Esra; Gültekin, Güzin Candan; Department of Biotechnology (2007)
This study was carried out to analyze tomato samples and tomato seeds, purchased from different food markets of Turkey randomly, for the presence of genetic modification by using PCR method as it allows more specific detection. The DNAs of collected samples were isolated according to CTAB DNA extraction protocol and also with extraction kits. Screening tests of tomatoes were done by targeting 35S promoter, NOS terminator and NptII kanamycin resistance gene with eight different primer sets. Real time PCR is ...
Morphometric and genetic differentiation between anatolia and Cyprus bonbus(bombus)terrestris (l.1758)populations
Beton, Damla; Kence, Aykut; Department of Biology (2004)
Four microsatellite loci were used to investigate differentiation in Bombus terrestris, a bumblebee of interest for its high value crops pollination. Two bumblebee populations, one from Ankara (the capital of Turkey) and one from North Cyprus were analyzed. In these populations, the total number of alleles detected per polymorphic locus ranged from 7 to 12. FST genetic distance between Ankara and North Cyprus B. terrestris populations based on four microsatellite loci was calculated as 0,09351. This applies...
Polymorphism of Prolactin (PRL), Diacylglycerol Acyltransferase (DGAT-1) and Bovine Solute Carrier Family 35 Member 3 (SLC35A3) genes in native cattle breeds and its implication for Turkish cattle breeding
Kepenek, Eda Şeyma; Togan, İnci Zehra; Department of Biology (2007)
In the present study samples from four native Turkish Cattle Breeds; South Anatolian Red (n= 48), East Anatolian Red (n= 34), Anatolian Black (n= 42) and Turkish Grey (n=46) and elite bulls of Holstein (n=21) were genotyped with respect to two milk production enhancer genes, Prolactin (PRL) and Diacylglycerol acyltransferase (DGAT1), and one disease (Complex Vertebral Malformation) causing gene (SLC35A3). A allele frequency for PRL gene, believed to be positively associated with the milk yield in cattle, ra...
Genetic relationships among perennial and annual Cicer species growing in Turkey assessed by AFLP fingerprinting
Sudupak, MA; Akkaya, Mahinur; Kence, A (Springer Science and Business Media LLC, 2004-03-01)
AFLP markers were used to assess genetic relationships among Cicer species with distribution in Turkey. Genetic distances were computed among 47 Cicer accessions representing four perennial and six annual species including chickpea, using 306 positions on AFLP gels. AFLP-based grouping of species revealed two clusters, one of which includes three perennial species, Cicer montbretii, Cicer isauricum and Cicer anatolicum, while the other cluster consists of two subclusters, one including one perennial, Cicer ...
