    Polo-like kinase-dependent phosphorylation of the synaptonemal complex protein SYP-4 regulates double-strand break formation through a negative feedback loop.

    Saravanapriah Nadarajan et al.
    PLK-1/2-mediated SYP-4 phosphorylation is dependent on crossover precursor formation, triggering a switch in the dynamic state of the synaptonemal complex that reduces the formation of further double-strand breaks at late meiotic prophase.

    Single molecule poly(A) tail-seq shows LARP4 opposes deadenylation throughout mRNA lifespan with most impact on short tails

    Sandy Mattijssen et al.
    LARP4 protects mRNAs against deadenylation over a wide range of poly(A) lengths but with most apparent functional impact on short lengths known to sensitize PABP binding and mRNA stability.

    LARP4 mRNA codon-tRNA match contributes to LARP4 activity for ribosomal protein mRNA poly(A) tail length protection

    Sandy Mattijssen et al.
    The messenger RNA encoding La-related protein-4 (LARP4) contains a short region of instability whose codon clusters are sensitive to low abundance tRNAs that when elevated increase LARP4 activity for poly(A) lengthening of ribosomal protein mRNAs and other mRNAs.

    Poly(A) tail length regulates PABPC1 expression to tune translation in the heart

    Sandip Chorghade et al.
    A poly(A) tail-based regulatory mechanism dynamically controls PABPC1 protein synthesis in cardiomyocytes and thereby titrates cellular translation in response to developmental and hypertrophic cues.

    JNK signaling triggers spermatogonial dedifferentiation during chronic stress to maintain the germline stem cell pool in the Drosophila testis

    Salvador C Herrera, Erika A Bach
    JNK pathway activity induces spermatogonial dedifferentiation under challenging conditions to maintain the germline stem cell pool and to endow it with potentially fitter cells that have increased proliferation.

    Manipulation of the human tRNA pool reveals distinct tRNA sets that act in cellular proliferation or cell cycle arrest

    Noa Aharon-Hefetz et al.
    Systematic CRISPR-based editing of tRNA genes revealed that different human cells that span a range of growth rates and different modes of proliferation states require diverse tRNA sets.

    Peptidoglycan precursor synthesis along the sidewall of pole-growing mycobacteria

    Alam García-Heredia et al.
    Peptidoglycan precursor synthesis occurs in both growing and non-growing regions of the mycobacterial cell surface.

    Identification of Pol IV and RDR2-dependent precursors of 24 nt siRNAs guiding de novo DNA methylation in Arabidopsis

    Todd Blevins et al.
    The 24-nucleotide long siRNAs that guide cytosine methylation in Arabidopsis are made by dicing short double-stranded RNAs that are only around 30 nucleotides long.

    Genetic and pharmacological evidence for kinetic competition between alternative poly(A) sites in yeast

    Rachael Emily Turner et al.
    The natural compounds cordycepin and mycophenolic acid stimulate alternative polyadenylation through opposing effects on transcriptional rate.
