Canalization of gene expression is a major signature of regulatory cold adaptation in temperate Drosophila melanogaster.

Abstract excerpt

BACKGROUND: Transcriptome analysis may provide means to investigate the underlying genetic causes of shared and divergent phenotypes in different populations and help to identify potential targets of adaptive evolution. Applying RNA sequencing to whole male Drosophila melanogaster from the ancestral tropical African environment and a very recently colonized cold-temperate European environment at both standard...
