Abstract

Back-up enhancers protect phenotype Transcriptional enhancers are segments of regulatory DNA located some distance from the coding region of a gene. Sometimes, several of them can serve apparently redundant functions — driving the production of a gene's messenger RNA at the same stage and place in embryonic development. Frankel et al. now demonstrate in Drosophila that such 'redundant' enhancers (in this case, two enhancers of the embryo-patterning gene shavenbaby), by contributing higher overall levels of transcription, ensure robustness of phenotypes against both genetic and environmental perturbations; for example, mutations in other genes or temperature changes that would otherwise lead to aberrant development.
