Expression profiling to identify adaptive gene expression responses. Changes in gene expression (red line vs. blue) are often correlated with adaptation to changes in the environment or genotypic alterations. Genome wide profiling of such expression changes can thus enable correlations or causal associations to be imputed between the affected genes and the trait of interest. Transcriptome analyses can also define transcriptional units (blue genes) that are co-expressed under varying conditions to allow annotations of unknown gene functions or associations between co-expressed genes.
