Uncovering the interaction between genomes and the environment is a principal challenge of modern genomics and preventive medicine. (nature.com)
Using whole-genome quantitative gene expression as a model, here we study how the genetic architecture of regulatory variation in gene expression changed in a population of fully sequenced inbred Drosophila melanogaster strains when flies developed in different environments (25 °C and 18 °C). We find a substantial fraction of the transcriptome exhibited genotype by environment interaction, implicating environmentally plastic genetic architecture of gene expression. (nature.com)
Finally, although genotype by environment interaction in gene expression could potentially disrupt genetic networks, the co-expression networks are highly conserved across environments. (nature.com)
Change in genetic variation across environments is one of the many forms of genotype by environment interaction (G×E). G×E can be interpreted equivalently either as variable genetic architecture across environments or as variable environmental plasticity across genotypes, depending on what factor is chosen as the context.

Three data analysis strategies were considered: one using a correctly specified disease model (exposure and exposure-gene interaction), and two using mis-specified disease models, one with "gene" as the only risk factor ("gene-only" model) and the other with main effects of both gene and exposure along with their interaction ("full" model).

The University of Miami is looking at the relationship between environmental factors and genes in persons living with ALS. (cdc.gov)

Gene-environment correlations can arise by both causal and non-causal mechanisms. (wikipedia.org)
Three causal mechanisms giving rise to gene-environment correlations have been described. (wikipedia.org)
Evidence for the existence of gene-environment correlations has recently started to accrue from molecular genetic investigations. (wikipedia.org)
Correlations between high opsin diversity and bright environments, however, are tenuous. (datadryad.org)

2 However, there have been limited studies on the gene‐environment interactions that contribute to a PD diagnosis and none have been replicated. (health.mil)
