Abstract(s)
Deciphering the genetic basis of the process of adaptation of organisms has been
and remains one of the fundamental goals of evolutionary biology. Genomes contain
information related to the history of natural populations. The Iberian honey bee (Apis
mellifera iberiensis Engel 1999) exhibits a complex genetic diversity pattern of clinal variation
shaped not only by evolutionarily neutral processes but also by selection. Unravelling the
variation of subgenomic regions in this subspecies not only allows us to better understand
the complexity of clinal patterning, but also the identification of genetic variation involved
in local adaptation.
Several regions related to vision, xenobiotic detoxification, and immune response have
shown signals of selection in A. m. iberiensis. In this study, analyses of sequence variation
around candidate subgenomic regions (~100 kpb) have been carried out. The aims of this
work are to provide further evidence of positive selection in the Iberian honey bee, to
localize at a much finer scale the direct points of such selection, and to find the underlying
source of the beneficial alleles or variants.
