Individual development unfolds through a dynamic interplay of regulatory elements, including environmental inputs. This chapter provides a general overview of the mechanisms currently understood to regulate gene expression, including transcription factors and other genetic interactions, alternative splicing and editing of coding sequences, epigenetic methylation and histone modifications, and noncoding RNAs. A key point is that “normal” development is influenced by environmental as well as molecular factors. The chapter argues for a unified ecological development approach that explicitly studies both expression mechanisms and phenotypic outcomes in environmental context. Central to this eco-devo approach is the norm of reaction, the set of phenotypes that a genotype produces in response to specific conditions. A discussion of genotype × environment (G × E) interaction draws on recent examples. In this unified approach to development, plasticity and canalization describe different response patterns but not distinct biological mechanisms. Finally, experimental design issues are briefly addressed.

Keywords:   gene expression, regulatory interaction, epigenetics, norm of reaction, genotype × environment interaction, G × E, plasticity, canalization, ecological development
