    Genome-wide mapping of native co-localized G4s and R-loops in living cells

    Ting Liu, Xing Shen ... Zhihong Xue
    The newly developed antibody-free techniques, HepG4-seq for G-quadruplexes and HBD-seq for R-loops, robustly reveal the comprehensive maps of native G-quadruplexes and R-loops, as well as their roles in transcriptional regulation.

    FRET kinase sensor development reveals SnRK2/OST1 activation by ABA but not by MeJA and high CO2 during stomatal closure

    Li Zhang, Yohei Takahashi ... Julian I Schroeder
    Development of a real-time SnRK2 kinase FRET reporter reveals rapid SnRK2 activation by ABA, but not by Methyl-Jasmonate or elevated CO2, while directly demonstrating basal SnRK2 activity in guard cells.

    Expression of a CO2-permeable aquaporin enhances mesophyll conductance in the C4 species Setaria viridis

    Maria Ermakova, Hannah Osborn ... Susanne von Caemmerer
    The SiPIP2;7 aquaporin is a functional CO2 pore that can be used to improve CO2 diffusion at the interface between the airspace and leaf mesophyll which limits C4 photosynthesis.

    Presynaptic NMDARs cooperate with local spikes toward GABA release from the reciprocal olfactory bulb granule cell spine

    Vanessa Lage-Rupprecht, Li Zhou ... Veronica Egger
    The essential role of presynaptic NMDA receptors for granule cell GABAergic output elucidates the function of reciprocal spines in recurrent and possibly lateral inhibition of mitral cells during olfactory processsing.

    Organelle proteomic profiling reveals lysosomal heterogeneity in association with longevity

    Yong Yu, Shihong M Gao ... Meng C Wang
    First systemic lysosomal proteomes in association with longevity and tissue specificity in C. elegans uncover lysosomal heterogeneity across multiple scales and provide valuable resources for understanding how lysosomes modulate signal transduction, organelle communication, tissue physiology, and organism longevity.

    TrpML-mediated astrocyte microdomain Ca2+ transients regulate astrocyte–tracheal interactions

    Zhiguo Ma, Marc R Freeman
    Astrocyte microdomain calcium transients are mediated by TrpML, stimulated by ROS and tyramine, and mediate astrocyte–tracheal interactions in CNS gas exchange.

    Investigating the composition and recruitment of the mycobacterial ImuA′–ImuB–DnaE2 mutasome

    Sophia Gessner, Zela Alexandria-Mae Martin ... Digby F Warner
    The interaction of ImuB with the β sliding clamp is essential for induced mutagenesis in mycobacteria and could be a novel target for new anti-tuberculosis drugs designed to inhibit the emergence of genetic resistance.
