    Functional divergence of paralogous transcription factors supported the evolution of biomineralization in echinoderms

    Jian Ming Khor, Charles A Ettensohn
    A gene duplication event has permitted the functional specialization of a homeodomain transcription factor through changes in exon-intron organization and these changes have supported the evolution of a major, phylum-level morphological novelty.

    The CDK-PLK1 axis targets the DNA damage checkpoint sensor protein RAD9 to promote cell proliferation and tolerance to genotoxic stress

    Takeshi Wakida et al.
    Minimizing anti-proliferation signaling from DNA damage detection machinery is the tactic for the cells to drive proliferation under genotoxic environment, and the function is exerted by Polo-Like-Kinase1 that is frequently over-expressed in cancer cells.

    A chloroplast retrograde signal, 3’-phosphoadenosine 5’-phosphate, acts as a secondary messenger in abscisic acid signaling in stomatal closure and germination

    Wannarat Pornsiriwong et al.
    Molecular signals from chloroplasts can synergistically interact with the plant hormone, abscisic acid (ABA), to regulate non-canonical signaling pathways mediating fundamental cellular processes including stomatal closure, seed dormancy and germination.

    A circuit motif in the zebrafish hindbrain for a two alternative behavioral choice to turn left or right

    Minoru Koyama et al.
    Competition between neurons on the left and right sides of the brain drives the decision to turn left versus right in zebrafish, and potentially all vertebrates.

    Maintenance of age in human neurons generated by microRNA-based neuronal conversion of fibroblasts

    Christine J Huh et al.
    MicroRNA-based direct conversion of human fibroblasts to neurons is applicable to fibroblasts from donors ranging in age from neonatal to centenarian, allowing the generation of neurons that maintain the age-associated signatures of the starting fibroblasts.

    T-box3 is a ciliary protein and regulates stability of the Gli3 transcription factor to control digit number

    Uchenna Emechebe et al.
    The transcription and splicing factor T-box3 is present in primary cilia, regulates multiple aspects of limb development, and interacts with members of the protein complex required for the stability and processing of the Gli3 transcription factor.

    Formation of polarity convergences underlying shoot outgrowths

    Katie Abley et al.
    Models that generate tandem alignments of cell polarities are more readily compatible with the formation of PIN1 polarity patterns in plant leaf buds than the most widely accepted “up-the-gradient” model.

    Aurora-A mediated histone H3 phosphorylation of threonine 118 controls condensin I and cohesin occupancy in mitosis

    Candice L Wike et al.
    A histone modification that alters the nucleosome structure occurs in mitosis and promotes chromosome packaging and the timely removal of condensin I and cohesion, to achieve chromosome segregation.

    The genetic basis for ecological adaptation of the Atlantic herring revealed by genome sequencing

    Alvaro Martinez Barrio et al.
    Whole genome sequencing of 19 populations of Atlantic and Baltic herring reveals hundreds of individual loci underlying adaptation to a low salinity niche or timing of reproduction.
