Deep conservation of cis-regulatory elements in metazoans.
Despite the vast morphological variation observed across phyla, animals share multiple basic developmental processes orchestrated by a common ancestral gene toolkit. These genes interact with each other building complex gene regulatory networks (GRNs), which are encoded in the genome by cis-regulatory elements (CREs) that serve as computational units of the network. Although GRN subcircuits inv...
متن کاملEvolution of lineage-specific functions in ancient cis-regulatory modules
Morphological evolution is driven both by coding sequence variation and by changes in regulatory sequences. However, how cis-regulatory modules (CRMs) evolve to generate entirely novel expression domains is largely unknown. Here, we reconstruct the evolutionary history of a lens enhancer located within a CRM that not only predates the lens, a vertebrate innovation, but bilaterian animals in gen...
متن کاملMultigenome DNA sequence conservation identifies Hox cis-regulatory elements.
To learn how well ungapped sequence comparisons of multiple species can predict cis-regulatory elements in Caenorhabditis elegans, we made such predictions across the large, complex ceh-13/lin-39 locus and tested them transgenically. We also examined how prediction quality varied with different genomes and parameters in our comparisons. Specifically, we sequenced approximately 0.5% of the C. br...
متن کاملTransposable elements donate lineage-specific regulatory sequences to host genomes.
The evolutionary implications of transposable element (TE) influences on gene regulation are explored here. An historical perspective is presented to underscore the importance of TE influences on gene regulation with respect to both the discovery of TEs and the early conceptualization of their potential impact on host genome evolution. Evidence that points to a role for TEs in host gene regulat...
متن کاملIn vivo competition identifies positive cis-regulatory elements required for lineage-specific gene expression in the sea urchin embryo.
Several cis-regulatory elements within the 5' regulatory region of the lineage-specific CyIIIa actin gene have been identified by in vivo competition. Sea urchin eggs were coinjected with a fusion construct in which the bacterial chloramphenicol acetyltransferase (CAT) gene is controlled by the CyIIIa regulatory domain, together with molar excesses of various DNA subfragments that are derived f...
