Genetic Structure Analysis Of Honeybee Populations Based On Microsatellites

We analyzed the genetic structures of 11 honeybee (Apis mellifera) populations from
T&uuml / rkiye and one population from Cyprus using 9 microsatellite loci. Average gene
diversity levels were found to change between 0,542 and 0,681. Heterozygosity levels,
mean number of alleles per population, presence of diagnostic alleles and pairwise FST
values confirmed the mitochondrial DNA finding that Anatolian honeybees belong to north
Mediterranean (C) lineage. We detected a very high level of genetic divergence among
populations of T&uuml / rkiye and Cyprus based on pairwise FST levels (between 0,0 and 0,2). Out
of 66 population pairs 52 were found to be genetically different significantly. This level of
significant differentiation has not been reported yet in any other study conducted on
European and African honeybee populations. High allelic ranges, and high divergence
indicate that Anatolia is a genetic centre for C lineage honeybees.
We suggest that certain precautions should be taken to limit or forbid introduction and trade
of Italian and Carniolan honeybees to T&uuml / rkiye and Cyprus in order to preserve genetic
resources formed in these territories in thousands of years. Effectivity at previously isolated
regions in Artvin, Ardahan and Kirklareli was confirmed by the high genetic differentiation
in honeybees of these regions. Genetically differentiated Karaburun and Cyprus honeybees
v
and geographical positions of the regions make these zones first candidates as new isolation
areas.
