    A gene regulatory network for neural induction

    Katherine E Trevers, Hui-Chun Lu ... Claudio D Stern
    A comprehensive resource based on analysis of the responses of embryonic ectoderm cells to signals from the 'organizer' (the node) including transcriptional responses and epigenetic changes with fine temporal dynamics, predicted regulatory interactions, and conservation among vertebrates.

    The Mutationathon highlights the importance of reaching standardization in estimates of pedigree-based germline mutation rates

    Lucie A Bergeron, Søren Besenbacher ... Mikkel H Schierup
    This first comparison of different methodologies to estimate germline mutation rate from pedigrees resulted in almost a 2-fold variation in the estimated rates, discrepancies mainly caused by different filtering methods.

    Drosophila Nanos acts as a molecular clamp that modulates the RNA-binding and repression activities of Pumilio

    Chase A Weidmann, Chen Qiu ... Aaron C Goldstrohm
    Crystal structures of Nanos bound to Pumilio and target RNAs demonstrate how Nanos forms a molecular clamp to alter Pumilio RNA regulation and specificity in embryonic development and germline maintenance.

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

    David Secco, Chuang Wang ... Ryan Lister
    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.

    The Drosophila Nab2 RNA binding protein inhibits m6A methylation and male-specific splicing of Sex lethal transcript in female neuronal tissue

    Binta Jalloh, Carly L Lancaster ... Ken Moberg
    The disease-associated RNA binding protein Nab2 is required to inhibit m6A RNA methylation in female Drosophila neuronal tissue and controls key splicing events such as sex-specific splicing of the Sex-lethal RNA.

    A missense in HSF2BP causing primary ovarian insufficiency affects meiotic recombination by its novel interactor C19ORF57/BRME1

    Natalia Felipe-Medina, Sandrine Caburet ... Alberto M Pendás
    Genetic and biochemical analysis reveal a variant in HSF2BP causing POI and C19ORF57/BRME1 as an interactor and stabilizer of HSF2BP by forming a complex with BRCA2, RAD51, RPA and PALB2.

    Gene expression mapping of the neuroectoderm across phyla – conservation and divergence of early brain anlagen between insects and vertebrates

    Nico Posnien, Vera S Hunnekuhl, Gregor Bucher
    Hypotheses on brain homologies between insects and vertebrates are tested by comparing gene expression patterns from flies and beetles with those from vertebrates at early neuroectoderm stages.

    Emergence of a smooth interface from growth of a dendritic network against a mechanosensitive contractile material

    Medha Sharma, Tao Jiang ... Tony JC Harris
    A smooth and circular interface can form between domains of the cell cortex from local induction of a contractile actomyosin ring by centrifugal pushing forces of an expanding Arp2/3 actin network.

    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.
