Genomic analysis of differentiation between soil types reveals candidate genes for local adaptation in Arabidopsis lyrata.

Serpentine soil, which is naturally high in heavy metal content and has low calcium to magnesium ratios, comprises a difficult environment for most plants. An impressive number of species are endemic to serpentine, and a wide range of non-endemic plant taxa have been shown to be locally adapted to t...
