    A DCL3 dicing code within Pol IV-RDR2 transcripts diversifies the siRNA pool guiding RNA-directed DNA methylation

    Andrew Loffer, Jasleen Singh ... Craig S Pikaard
    Double-stranded precursors of siRNAs involved in RNA-directed DNA methylation have initiating sequences and overhangs imparted by the RNA polymerases that synthesize them, programming alternative dicing reactions that diversify the siRNA pool.

    Host-pathogen genetic interactions underlie tuberculosis susceptibility in genetically diverse mice

    Clare M Smith, Richard E Baker ... Christopher M Sassetti
    A novel dual genome approach that combines genetically diverse mice and a library of bacterial mutants to define the genome-wide host pathogen interactions that drive distinct outcomes to tuberculosis.

    Genetic integration of behavioural and endocrine components of the stress response

    Thomas M Houslay, Ryan L Earley ... Alastair Wilson
    Behavioural and physiological stress response components are integrated on the major axis of genetic covariation, with implications for health and the understanding of the evolutionary response to stressors.

    Distinguishing between recruitment and spread of silent chromatin structures in Saccharomyces cerevisiae

    Molly Brothers, Jasper Rine
    Heterochromatin proteins like the SIR complex in budding yeast use different mechanisms for recruitment to nucleation sites and long-range spread to create a domain of transcriptional silencing.

    Differences in pathways contributing to thyroid hormone effects on postnatal cartilage calcification versus secondary ossification center development

    Gustavo A Gomez, Patrick Aghajanian ... Subburaman Mohan
    Mouse molecular genetics and in vivo functional studies reveal that thyroid hormone is necessary for punctual proximal femur head development by a mechanism that differs temporally and molecularly from the secondary ossification center at the distal femur.

    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.

    Human embryoid bodies as a novel system for genomic studies of functionally diverse cell types

    Katherine Rhodes, Kenneth A Barr ... Yoav Gilad
    Embryoid bodies produce diverse cell types and can enable the study of gene regulatory dynamics at unprecedented spatial and temporal resolution.

    Functional CDKN2A assay identifies frequent deleterious alleles misclassified as variants of uncertain significance

    Hirokazu Kimura, Raymond M Paranal ... Nicholas J Roberts
    Over 40% of CDKN2A variants of uncertain significance identified in patients with pancreatic cancer are functionally deleterious and can be reclassified as likely pathogenic with implications for care of patients and their relatives.

    Multiple 9-1-1 complexes promote homolog synapsis, DSB repair, and ATR signaling during mammalian meiosis

    Catalina Pereira, Gerardo A Arroyo-Martinez ... Robert S Weiss
    Alternative 9-1-1 complexes have evolved to play essential roles in mammalian meiosis and function to activate the protein kinase ATR and promote key meiotic events necessary for fertility.

    FMRP regulates mRNAs encoding distinct functions in the cell body and dendrites of CA1 pyramidal neurons

    Caryn R Hale, Kirsty Sawicka ... Robert B Darnell
    Combining compartment- and cell-type specific transcriptomic approaches reveals FMRP regulation of synaptic regulators in the dendrites and chromatin regulators in the cell bodies of CA1 neurons.
