Understanding the genetic bases of biological diversification is a
long-standing goal in evolutionary biology. Here we investigate whether
replicated cases of adaptive divergence involve the same genomic regions
in the pea aphid, Acyrthosiphon pisum, a large complex of genetically
differentiated biotypes, each specialized on different species of legumes.
A previous study identified genomic regions putatively involved in
host-plant adaptation and/or reproductive isolation by performing a
hierarchical genome scan in three biotypes. This led to the identification
of 11 FST outliers among 390 polymorphic microsatellite markers. In this
study, the outlier status of these 11 loci was assessed in eight biotypes
specialized on other host plants. Four of the 11 previously identified
outliers showed greater genetic differentiation among these additional
biotypes than expected under the null hypothesis of neutral evolution
(α<0.01). Whether these hotspots of genomic divergence result from
adaptive events, intrinsic barriers or reduced recombination is discussed.

August 2011 within a 30 km-diameter location in Eastern France. Please
