    Multiple kinases inhibit origin licensing and helicase activation to ensure reductive cell division during meiosis

    David V Phizicky, Luke E Berchowitz, Stephen P Bell
    Meiotic cells inhibit two distinct steps of replisome assembly with multiple kinases to prevent DNA replication between Meiosis I and Meiosis II.

    Natural changes in light interact with circadian regulation at promoters to control gene expression in cyanobacteria

    Joseph Robert Piechura, Kapil Amarnath, Erin K O'Shea
    Cyanobacteria cope with both predictable day/night changes and natural fluctuations in light during the day by adjusting the expression dynamics of circadian-clock-controlled genes via a network of transcriptional regulators.

    Nonsense mRNA suppression via nonstop decay

    Joshua A Arribere, Andrew Z Fire
    Nonstop mRNA decay degrades mRNAs with a premature stop codon after such mRNAs are targeted by the nonsense-mediated decay machinery.

    Decoding the centromeric nucleosome through CENP-N

    Satyakrishna Pentakota, Keda Zhou ... Karolin Luger
    A comprehensive structural, biochemical, and cell biological analysis reveals the molecular mechanism and significance of the conserved interaction of centromeric protein N (CENP-N) with the centromeric nucleosome.

    Conserved noncoding transcription and core promoter regulatory code in early Drosophila development

    Philippe J Batut, Thomas R Gingeras
    Gene expression timing during Drosophila development is specified by multiple classes of RNA polymerase II core promoters, and the embryonic transcriptome includes thousands of evolutionarily conserved long noncoding RNAs.

    Cis-regulatory evolution integrated the Bric-à-brac transcription factors into a novel fruit fly gene regulatory network

    Maxwell J Roeske, Eric M Camino ... Thomas Michael Williams
    The conserved biochemical activity of the duplicate Bab transcription factors were integrated into the regulatory hierarchy of an evolving gene regulatory network by binding site gains in a target gene's cis-regulatory region.

    Context-dependent deposition and regulation of mRNAs in P-bodies

    Congwei Wang, Fabian Schmich ... Anne Spang
    An unbiased screen using various stresses reveals selective mRNA transport into P-bodies, in which mRNAs are either stored or decayed in a process that may promote chronological lifespan in yeast.

    Telomere repeats induce domains of H3K27 methylation in Neurospora

    Kirsty Jamieson, Kevin J McNaught ... Eric U Selker
    Vast regions of facultative heterochromatin marked by methylation of lysine 27 on histone H3 depend on their proximity to chromosome ends and can be induced ectopically by insertion of telomere repeats.

    cAMP signaling regulates DNA hydroxymethylation by augmenting the intracellular labile ferrous iron pool

    Vladimir Camarena, David W Sant ... Gaofeng Wang
    cAMP is identified to play a novel role in regulating DNA demethylation and gene transcription by augmenting the intracellular reactive Fe(II) pool.

    Natural variation in stochastic photoreceptor specification and color preference in Drosophila

    Caitlin Anderson, India Reiss ... Robert J Johnston
    Binding site affinity and transcription factor levels are finely tuned in nature to regulate stochastic expression, setting the ratio of alternative photoreceptor fates and determining color preference.
