    Zygotic gene activation in the chicken occurs in two waves, the first involving only maternally derived genes

    Young Sun Hwang et al.
    In Aves, the first wave of transcription is derived exclusively from the maternal genome.

    Subdued, a TMEM16 family Ca2+-activated Cl channel in Drosophila melanogaster with an unexpected role in host defense

    Xiu Ming Wong et al.
    A newly characterized calcium-activated chloride channel has been implicated in the immune system of Drosophila, shedding light on an enigmatic family of transmembrane proteins that are ubiquitous in nature.

    A disassembly-driven mechanism explains F-actin-mediated chromosome transport in starfish oocytes

    Philippe Bun et al.
    On entry to meiosis, chromosomes scattered in the large oocyte nucleus of starfish are collected by an F-actin network, which contracts by an unexpected, myosin-independent mechanism based on local assembly and global disassembly of actin filaments.

    Glycosylphosphatidylinositol-anchored proteins as chaperones and co-receptors for FERONIA receptor kinase signaling in Arabidopsis

    Chao Li et al.
    FERONIA receptor kinase interacts with phosphatidylinositol-anchored proteins LORELEI and LLG1 to ensure its proper functional location in the cell membrane and engages them as co-receptors on the cell surface to mediate a broad spectrum of growth and signaling processes.
