Gene expression remodelling and immune response during adaptive divergence in an African cichlid fish [PDF]
Molecular Ecology, Volume 30, Issue 1, Page 274-296, January 2021., 2021 Abstract Variation in gene expression contributes to ecological speciation by facilitating population persistence in novel environments. Likewise, immune responses can be of relevance in speciation driven by adaptation to different environments. Previous studies examining gene expression differences between recently diverged ecotypes have often relied ...
