The Footprint of Polygenic Adaptation on Stress-Responsive Cis-Regulatory Divergence in the Arabidopsis Genus.

abstract：:We compared the single-nucleotide polymorphisms (SNPs) in humans in 182 housekeeping and 148 tissue-specific genes. SNPs were divided into rare and common polymorphisms based on their frequencies. We found that housekeeping genes tend to be less polymorphic than tissue-specific genes for both rare and common SNPs. Usi...
