    Long-term balancing selection drives evolution of immunity genes in Capsella

    Daniel Koenig et al.
    Retention of genetic diversity at immune-related loci drives the pattern of genetic variation in selfing Capsella.

    Deployment of a retinal determination gene network drives directed cell migration in the sea urchin embryo

    Megan L Martik, David R McClay
    The gene regulatory network controlling directed cell migration in a sea urchin is strikingly similar to a sub-circuit for eye development in Drosophila, suggesting that ancient systems-level controls may be adapted for diverse functions in different animals.

    Targeted, homology-driven gene insertion in stem cells by ZFN-loaded ‘all-in-one’ lentiviral vectors

    Yujia Cai et al.
    Building on previous work (Cai et al., 2014), HIV-derived lentiviral vectors are harnessed to insert user-defined genes into a safe locus in the genome of human stem cells.

    ASH1-catalyzed H3K36 methylation drives gene repression and marks H3K27me2/3-competent chromatin

    Vincent T Bicocca et al.
    While SET-2 methylates histone H3K36 during transcription, ASH1 methylates this residue in repressed regions, is important for silencing, and can both positively and negatively influence methylation of histone H3K27.

    Evolution of substrate specificity in a retained enzyme driven by gene loss

    Ana Lilia Juárez-Vázquez et al.
    An integrated biochemical and evolutionary analysis shows how enzyme specificity evolves after gene loss during genome decay, implicating relaxation of purifying selection as a driving force for functional divergence.

    Gene Drive: A family of killers

    Mickaël De Carvalho, Sarah E Zanders
    Spok genes are meiotic drivers that increase their own chances of transmission by killing gametes that do not inherit them.

    Gene-specific mechanisms direct glucocorticoid-receptor-driven repression of inflammatory response genes in macrophages

    Maria A Sacta et al.
    A comprehensive analysis of the glucocorticoid-sensitive pro-inflammatory genes in macrophages reveals fundamental differences between the temporal events and components of transcriptional machinery that the glucocorticoid receptor targets to repress their transcription.

    Stress induced gene expression drives transient DNA methylation changes at adjacent repetitive elements

    David Secco et al.
    Phosphate starvation in rice induces widespread, but transient, modulation of DNA methylation near stress responsive genes that is independent from the RNA-directed DNA methylation pathway.

    Distinct modes of SMAD2 chromatin binding and remodeling shape the transcriptional response to NODAL/Activin signaling

    Davide M Coda et al.
    NODAL/Activin-induced SMAD2 binding directly drives remodeling of both open and closed chromatin and does not directly correlate with temporal patterns of gene expression upon prolonged signaling.
