Genetic diversity of honey bee (Apis mellifera L.: Hymenoptera: Apidae) populations in Turkey revealed by RAPD markers

Kence, Meral
The honeybee, Apis mellifera L. is an ecologically and economically important insect species. Recent honey bee losses causing decline of bee diversity is found alarming for the pollination of both wild plant biodiversity and crop production. Therefore, determination of genetic diversity of honey bee populations is essential and will provide a valuable resource for conservation purposes. Twenty Random Amplified Polymorphic DNA (RAPD) primers were used to assess the genetic diversity in 720 worker bees collected from 360 colonies of 25 provinces in Turkey. Ten out of twenty primers produced 105 reproducible, bright bands, all were polymorphic. Mean genetic diversity values ranged between 0.035 and 0.175, coefficient of gene differentiation (G(ST)) values were estimated as 0.060 to 0.441, and the private band patterns reflected a high level of genetic variation. Analysis of Molecular Variance (AMOVA) partitioned the total genetic variation as 60% within, 40% among populations. The Mantel test did not reveal significant correlation between the genetic and geographic distances. First three Eigen values of principle coordinate analysis explained 63% of total variation, 27, 21, and 15% for the first, second and third respectively. The cluster analysis showed that the honey bees of Thrace region of Turkey and an island at a short distance were clustered together. The other two populations from southeastern Anatolia which belong to African lineage according to mitochondrial DNA analysis formed a separate cluster and rest of the populations which belong to north Mediterranean branch (C lineage) formed the third cluster. The results showed that genetic variability of honey bee populations from Turkey are determined using RAPD markers and provide information for future management and conservation plans.


Genetic diversity of honey bee populations in Turkey based on microsatellite markers : a comparison between migratory versus stationary apiaries and isolated regions versus regions open to migratory beekeeping
Kükrer, Mert; Kence, Aykut; Department of Biology (2013)
The honey bee (Apis mellifera L.) is a globally significant species of apparent economic and ecological importance. Recent reports from Spain, Italy and Greece point to an intense admixture of honey bee populations signified by a loss of population structure. This is mostly attributed to migratory beekeeping practices and replacement of queens or colonies with commercial ones that are usually from non-native races or hybrids of different subspecies. These two practices are also heavily carried out in parts ...
Genetic structure of honeybee, Apis mellifera L. (Hymenoptera : Apidae) populations of Turkey inferred from microsatellite analysis
Bodur, Cagri; Kence, Meral; Kence, Aykut (2007-01-01)
We analyzed the genetic structure of 11 honeybee (Apis mellifera L) populations from Turkey and one from Cyprus using 9 microsatellite marker loci. Heterozygosity levels, mean number of alleles per population, number of diagnostic alleles, and pairwise F-ST values were computed for the populations studied. Heterozygosity levels were found to range between 0.54 and 0.68. We detected high levels of genetic divergence among the populations based on pairwise F-ST values; 50 of 66 pairwise F-ST values were signi...
Genetic differentiation between clone collections and natural populations of European black poplar (Populus nigra L.) in turkey
Çiftçi, Asiye; Kucukosmanoglu, Filiz; Karahan, Alptekin; Kaya, Zeki (2017-06-01)
The European black poplar (Populus nigra L.) is an ecologically and economically important tree species for Turkey. The important and major genetic resources of species for future breeding and ex situ conservation purposes have been archived in a clone bank in Ankara by selecting clones from natural populations and old plantations throughout Turkey. There is no study to date assessing genetic composition these materials. Two-hundred-thirty-three P. nigra clones from six geographic region of Turkey (clone co...
Genetic diversity pattern in Populus Nigra populations of two major river systems in Turkey
Çiftçi, Asiy; Kaya, Zeki; Department of Biology (2019)
European black poplar (Populus nigra L.) is an important tree species in terms of social, economic and ecological interest in Turkey. Although, poplar plantations in large areas meet the needs of the economy, the natural genetic resources of the species have been highly degraded due to anthropogenic effects and natural biological events. To assess genetic diversity structure of natural populations, 124 naturally distributed European black poplar trees from two major rivers (Kızılırmak and Göksu) in Turkey w...

Genetic variation of honey bee populations from 9 different locations of Bulgaria was studied using 4 enzymic systems (MDH, ME, EST and ALP) corresponding to 4 genetic loci and PCR-RFLP's analysis of 16s rDNA, COI, and ND5 gene segments of mtDNA. Allozyme analysis revealed that all loci were polymorphic in almost all studied populations. The observed heterozygosity was found to range from 0.146 to 0.258, and Nei's genetic distance between 0.006 and 0.057 among the populations. Bulgarian honey bees are clust...
