    Intrinsic cooperativity potentiates parallel cis-regulatory evolution

    Trevor R Sorrells et al.
    Cooperativity between two transcription regulators occurs through protein-protein interactions with a general transcription factor complex and potentiates the parallel evolution of their DNA binding sites.

    Predominance of cis-regulatory changes in parallel expression divergence of sticklebacks

    Jukka-Pekka Verta, Felicity C Jones
    Cis-regulation such as enhancers and promoters plays a major role in parallel gene expression divergence and has features that make it a well-poised substrate for adaptive evolution.

    An integrative genomic analysis of the Longshanks selection experiment for longer limbs in mice

    João PL Castro et al.
    Genome sequencing of mice selected for longer limbs reveals that rapid selection response is due to both discrete loci and polygenic adaptation.

    Deciphering the regulatory genome of Escherichia coli, one hundred promoters at a time

    William T Ireland et al.
    A combination of massively parallel reporter assays and mass spectrometry uncovers the regulation of previously unexplored promoters across the Escherichia coli genome.

    The evolutionary plasticity of chromosome metabolism allows adaptation to constitutive DNA replication stress

    Marco Fumasoni, Andrew W Murray
    Evolutionary adaptation to a constitutive perturbation of DNA replication reveals that adaptive mutations in three conserved pathways interact to restore faithful chromosome replication and segregation.

    Environment determines evolutionary trajectory in a constrained phenotypic space

    David T Fraebel et al.
    Experimental evolution shows that when selection acts on two traits constrained by a trade-off, the direction of phenotypic evolution depends on the environment.
