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 clustered into three groups in neighbor-joining and UPGMA dendrograms. The Pomorie and Slivovik populations are in a separate clade while all other populations are grouped together. The mtDNA analyses revealed no variation in the Bulgarian honey bees.


Genetic structure of black pine (Pinus nigra ARNOLD subspecies pallasiana) populations sampled from the Bolkar Mountains
Tolun, AA; Velioğlu, E; Çengel, Burcu N; Kaya, Zeki (2000-01-01)
In order to determine the magnitude and pattern of genetic diversity among Anatolian Black pine (Pinus nigra ARNOLD subspecies pallasiana) populations sampled in Bolkar Mountains and to recommend the potential populations which may be suitable for in situ conservation of genetic resources in this species, isoenzymes from 14 enzyme systems were investigated by starch gel electrophoresis. For this reason, open pollinated seed megagametophytes of half-sib families originated from the four populations (Camliyay...
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 control of rooting ability of lodgepole pine cuttings
Fries, A; Kaya, Zeki (1997-11-01)
This study evaluates the genetic control of rooting ability ex vitro for cuttings of lodgepole pine (Pinus contorta var. latifolia Engelm.). More than 200 clones from 21 full-sib families were studied during 4 yr in the greenhouse. Clonal averages in rooting frequency, root size score, shoot extension during rooting, and vitality score were calculated, together with variance components and phenotypic and genetic correlations among variables. Years, families within latitude of origin, clones within families ...
Genetic differentiation of Abies equi-trojani (Asch. & Sint. ex Boiss) Mattf. populations from Kazdaǧι, Turkey and the genetic relationship between Turkish firs belonging to the Abies nordmanniana Spach complex
Kaya, Zeki; Neale, David Brian (2008-02-05)
The present study aimed to test the utility of RAPD (randomly amplified polymorphic DNA) and cpSSR (simple sequence repeats) markers for in situ gene conservation programs for fir species, as well as for determining the genetic similarities between the Abies nordmanniana Spach species complex (A. nordmanniana, A. bornmuelleriana Matff., A. equi-trojani (Asch. & Sint. ex Boiss) Mattf.) and between populations of A. equi-trojani, which is a narrow-endemic to Turkey. For this purpose, DNA was extracted and poo...
Phylogeography and Population Genetics of Honey Bees (Apis mellifera) From Turkey Based on COI-COII Sequence Data
Solorzano, Cesar D.; Szalanski, Allen L.; Kence, Meral; McKern, Jackie A.; Austin, James W.; Kence, Aykut (2009-01-01)
A study that involved DNA sequencing of COI-COII intergenic region of the mitochondrial DNA genome of Apis mellifera honey bees from Turkey was conducted to determine the population genetics and phylogeographic structure of this species from seven distinct areas of Turkey. From the 132 honey bees subjected to DNA sequencing, a total of 12 mitotypes of A. mellifera "C" lineage were observed, of which only one mitotype, C 13, had been reported previously. The most common mitotype, C12, accounted for 47% of th...
