Data from: Genetic basis of octanoic acid resistance in Drosophila sechellia: functional analysis of a fine-mapped region

Jose M. Andrade López, Stephen M. Lanno, Jeremy M. Auerbach, Eva C. Moskowitz, Laura A. Sligar, Patricia J. Wittkopp & Joseph D. Coolon
Drosophila sechellia is a species of fruit fly endemic to the Seychelles islands. Unlike its generalist sister species, D. sechellia has evolved to be a specialist on the host plant Morinda citrifolia. This specialization is interesting because the plant's fruit contains secondary defense compounds, primarily octanoic acid (OA), that are lethal to most other Drosophilids. Although ecological and behavioral adaptations to this toxic fruit are known, the genetic basis for evolutionary changes in OA resistance...

Data from: The genetics of extreme microgeographic adaptation: an integrated approach identifies a major locus underlying leaf trichome divergence in Yellowstone Mimulus guttatus

Margaret F. Hendrick, Findley R. Finseth, Minna E. Mathiasson, Kristen A. Palmer, Emma M. Broder, Peter Breigenzer & Lila Fishman
Microgeographic adaptation provides a particularly interesting context for understanding the genetic basis of phenotypic divergence, and may also present unique empirical challenges. In particular, plant adaptation to extreme soil mosaics may generate barriers to gene flow or shifts in mating system that confound simple genomic scans for adaptive loci. Here, we combine three approaches - QTL mapping of candidate intervals in controlled crosses, population resequencing (PoolSeq), and analyses of wild recombinant individuals - to investigate...

Data from: DNA methylation mediates genetic variation for adaptive transgenerational plasticity

Jacob J. Herman & Sonia E. Sultan
Environmental stresses experienced by individual parents can influence offspring phenotypes in ways that enhance survival under similar conditions. Although such adaptive transgenerational plasticity is well documented, its transmission mechanisms are generally unknown. One possible mechanism is environmentally induced DNA methylation changes. We tested this hypothesis in the annual plant Polygonum persicaria, a species known to express adaptive transgenerational plasticity in response to parental drought stress. Replicate plants of 12 genetic lines (sampled from natural populations)...
