    The human gut chemical landscape predicts microbe-mediated biotransformation of foods and drugs

    Leah Guthrie et al.
    A network of the gut chemical landscape predicts microbe-mediated biotransformation of foods and drugs and supports the generation of mechanistic hypotheses of microbiome metabolic phenotypes that shape human biology.

    Live-cell imaging reveals enhancer-dependent Sox2 transcription in the absence of enhancer proximity

    Jeffrey M Alexander et al.
    Sox2 transcription is not correlated with spatial proximity of its essential regulatory enhancer in embryonic stem cells, suggesting gene transcription is not limited to periods of direct enhancer-promoter contact.

    The plant pathogen Pseudomonas aeruginosa triggers a DELLA-dependent seed germination arrest in Arabidopsis

    Hicham Chahtane et al.
    Arabidopsis seed germination can be repressed by a Pseudomonas factor.

    Antimicrobial peptide expression in a wild tobacco plant reveals the limits of host-microbe-manipulations in the field

    Arne Weinhold et al.
    The attempt to manipulate a microbiome in planta to study the ecological consequences under field conditions leaves plants and their microbes surprisingly unimpressed.

    Functional role of the type 1 pilus rod structure in mediating host-pathogen interactions

    Caitlin N Spaulding et al.
    The helical rod structure and dynamic spring-like properties of the type 1 pilus are evolutionarily fine-tuned for functioning in host-pathogen interactions during urinary tract infection and gut colonization.

    An evolutionarily young defense metabolite influences the root growth of plants via the ancient TOR signaling pathway

    Frederikke Gro Malinovsky et al.
    Young defense metabolites are often believed to be solely outputs but evidence suggests that they can regulate ancient signaling pathways.

    Adaptive tuning of mutation rates allows fast response to lethal stress in Escherichia coli

    Toon Swings et al.
    Population mutation rates are highly flexible and evolvable under extreme stress conditions, matching changes in selective pressure to avoid extinction of the entire population.

    Impaired respiration elicits SrrAB-dependent programmed cell lysis and biofilm formation in Staphylococcus aureus

    Ameya A Mashruwala et al.
    The absence of oxygen prompts Staphylococcus aureus cells to rupture resulting in increased formation of biofilms, which are the etiological agents of recurrent infections.

    Coincidence detection and bi-directional transmembrane signaling control a bacterial second messenger receptor

    Richard B Cooley et al.
    Building on previous work (Chatterjee et al., 2014), the mechanism of coincidence detection in bacterial second messenger signaling across membranes is revealed at a molecular level, providing insight into the regulation of a conserved transmembrane receptor.
