bric à brac (bab), a central player in the gene regulatory network that mediates thermal plasticity of pigmentation in Drosophila melanogaster.

Abstract excerpt

Drosophila body pigmentation has emerged as a major Evo-Devo model. Using two Drosophila melanogaster lines, Dark and Pale, selected from a natural population, we analyse here the interaction between genetic variation and environmental factors to produce this complex trait. Indeed, pigmentation varies with genotype in natural populations and is sensitive to temperature during development. We demonstrate that the...
