    Computational design of environmental sensors for the potent opioid fentanyl

    Matthew J Bick et al.
    State-of-the-art computational methods have facilitated the construction of plant-based sentinels for detecting toxic molecules in the environment.

    Density-dependent resistance protects Legionella pneumophila from its own antimicrobial metabolite, HGA

    Tera C Levin et al.
    Legionella pneumophila can be inhibited by its own antimicrobial, HGA (homogentisic acid), but its density-dependent resistance to HGA restricts the potential for self-harm.

    NirD curtails the stringent response by inhibiting RelA activity in Escherichia coli

    Loïc Léger et al.
    Genetic and biochemical approaches uncover a novel mode of regulation of the alarmone synthetase RelA through a functional and direct interaction with the small subunit of the nitrite reductase NirD.

    A broadly distributed toxin family mediates contact-dependent antagonism between gram-positive bacteria

    John C Whitney et al.
    Diverse LXG toxins delivered by the Esx pathway function as mediators of contact-dependent interbacterial antagonism within and between Gram-positive bacterial species.

    Abundant toxin-related genes in the genomes of beneficial symbionts from deep-sea hydrothermal vent mussels

    Lizbeth Sayavedra et al.
    Beneficial symbiotic bacteria encode an exceptional number of toxin-related genes that are all expressed by the symbionts in the host, supporting their key role in host-microbe interactions.

    Bacterial Warfare: Toxins, mutations and adaptations

    Maarten De Jong, Neal M Alto
    The toxins that some bacteria secrete to kill off rival species can also generate mutations that help toxin-resistant populations adapt to new environments.

    Natural variation in C. elegans arsenic toxicity is explained by differences in branched chain amino acid metabolism

    Stefan Zdraljevic et al.
    Quantitative genetics approaches using Caenorhabditis elegans facilitate the discovery of a novel arsenic toxicity mechanism.

    Paternal nicotine exposure alters hepatic xenobiotic metabolism in offspring

    Markus P Vallaster et al.
    A novel paternal effect based on nicotine exposure reveals that offspring exhibit an adaptive, yet nonspecific, resistance to multiple toxins.

    Adaptive evolution of nontransitive fitness in yeast

    Sean W Buskirk et al.
    A series of selective events, each improving fitness relative to an immediate predecessor, can result in organisms that are less fit compared to a distant ancestor.

    Infectious polymorphic toxins delivered by outer membrane exchange discriminate kin in myxobacteria

    Christopher N Vassallo et al.
    Serial cell-to-cell transfer of lipoprotein toxins by outer membrane exchange provides a potent platform for kin discrimination in Myxococcus xanthus.
