ABSTRACT The genetic structure and phylogenetic relationships among six honey bee populations were studied using RFLP analysis on three PCR-amplified mtDNA gene segments (16s rDNA, CO I, and ND 5). The populations were sampled from various areas of Greece and Cyprus and correspond to Apis mellifera adami, A. m. macedonica, A. m. cecropia, and A. m. cypria races, based on origin (Ruttner, 1988). Seven, eight and seven restriction enzymes were found to have at least one recognition site at the 16s rDNA, CO I, and ND 5 segments, respectively. Seven different haplotypes were detected and diagnostic patterns enabled us to discriminate A. m. macedonica from the rest of the populations (races). The estimated net nucleotide sequence divergence among the populations examined was found to range from 0.00 to 1.18 with the highest value observed to be between A. m. macedonica and non-A. m. macedonica populations. The trees obtained (by UPGMA and Dollo parsimony methods) revealed that the most distant population was that of A. m. macedonica.

    ABSTRACT: Angiopolybia pallens is a swarm-founding wasp that occurs in Atlantic and Amazonian rainforests, which have been isolated from each other by a large arid corridor in central Brazil since the Tertiary. In this study, we used data from polymerase chain reaction-restriction fragment length polymorphism of 16S rDNA to infer some aspects of the genetic diversity and evolutionary history of this social wasp population. Samples collected across the species range in both rainforests showed remarkable differences that separated them into two distinct haplogroups. However, some samples from isolated areas in northeastern Bahia were more related to Amazonian lineages than to southern Bahia populations. Vicariant divergenc is discussed under South American rainforests biogeographical proposals.

    ABSTRACT: Mitochondrial DNA sequence variation can be used to infer honey bee evolutionary relationships. We examined DNA sequence diversity in the cytochrome C oxidase I (COI or Cox1) gene segment of the mitochondrial genome in 112 samples of Apis mellifera from 15 different populations in Turkey. Six novel haplotypes were found for the COI gene segment. There were eight variable sites in the COI gene, although only three were parsimony-informative sites. The mean pairwise genetic distance was 0.3% for the COI gene segment. Neighbor-joining (NJ) trees of the COI gene segment were constructed with the published sequences of A. mellifera haplotypes that are available in GenBank; the genetic variation was compared among the different honeybee haplotypes. The NJ dendogram based on the COI sequences available in GenBank showed that Eastern European races were clustered together, whereas the Mellifera and Iberian haplotypes were clustered far apart. The haplotypes found in this study were clustered together with A. mellifera ligustica and some of the Greek honey bees (accession Nos. GU056169 and GU056170) found in NCBI GenBank database. This study expands the knowledge about the mitochondrial COI region and presents the first comprehensive sequence analysis of this region in Turkish honeybees.

    ABSTRACT: Mitochondrial DNA sequence variation can be used to infer honeybee evolutionary relationships. In this study, DNA sequence diversity of the mitochondrial 16s rDNA region was investigated in 112 honeybees from 15 populations in Turkey, which is mainly populated with Apis mellifera anatoliaca, A. m. caucasica, and A. m. meda. The study revealed 11 haplotypes for this segment, with 13 variable sites and nine parsimony informative sites. The haplotypes were not discriminated according to their geographical locations in a neighbor-joining dendrogram based on 16s rDNA sequences available in Genbank, but all the haplotypes obtained in this study are clustered with published haplotypes such as A. mellifera TAS (AF214666) and A. m. ligustica (EF116868) and with some unpublished Genbank records (HQ318928, HQ318934, and HQ318938). This study expands the knowledge of the mitochondrial 16s rDNA region, and it presents the first comprehensive sequence analysis of this region in Turkish honeybees.
