Widespread cis– and trans-regulatory evolution underlies the origin, diversification, and loss of a sexually dimorphic fruit fly pigmentation trait
Jesse T. Hughes, Melissa E. Williams, Mark Rebeiz, Thomas M. Williams https://doi.org/10.1002/jez.b.23068 Abstract Changes in gene expression are a prominent feature of morphological evolution. These changes occur to hierarchical gene regulatory networks (GRNs) of transcription factor genes that regulate the … Continue reading

Cis-regulatory evolution integrated the Bric-à-brac transcription factors into a novel fruit fly gene regulatory network
Maxwell J Roeske, Eric M Camino, Sumant Grover, Mark Rebeiz, Thomas Michael Williams Cite as: eLife 2018;7:e32273 doi: 10.7554/eLife.32273 Abstract Gene expression evolution through gene regulatory network (GRN) changes has gained appreciation as a driver of morphological evolution. However, understanding … Continue reading
One primary agenda of the developmental evolution field is to elucidate molecular mechanisms governing differences in animal form. While mounting evidence has established an important role for mutations in transcription controlling cis-regulatory elements (CREs), the underlying mechanisms that translate these … Continue reading
Drosophilaphilia #2: Silencing silencers to evolve new patterns. Nice thoughtful overview on my collaborator’s new publication!
Collaborators publish a study showing how evolutionary changes in a transcriptional silencer shaped the repeated evolution of a fruit fly trait. Might be a first description of a pervasive mechanism of evolutionary change!
Genetic Changes to a Transcriptional Silencer Element Confers Phenotypic Diversity within and between Drosophila Species Winslow C. Johnson , Alison J. Ordway , Masayoshi Watada, Jonathan N. Pruitt, Thomas M. Williams, Mark Rebeiz Author Summary One of the greatest challenges … Continue reading
