    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 symbiont subpopulations have different roles in a deep-sea symbiosis

    Tjorven Hinzke et al.
    Physiological differentiation during symbiosis leads to division of labor between smaller and larger cells in an uncultured bacterial tubeworm symbiont population and results in remarkable metabolic diversity and complexity.

    Insight into the evolution of microbial metabolism from the deep-branching bacterium, Thermovibrio ammonificans

    Donato Giovannelli et al.
    The genome of Thermovibrio ammonificans encodes ancestral pathways (e.g., hydrogen oxidation) and more recently acquired ones (e.g., nitrate reduction) and a hybrid pathway for CO2 fixation.

    Molecular basis for the adaptive evolution of environment-sensing by H-NS proteins

    Xiaochuan Zhao et al.
    Combining in silico and experimental approaches to identify and understand the residue changes in the H-NS protein that allowed bacteria to adapt environment-sensing to different habitats.

    Flower-like patterns in multi-species bacterial colonies

    Liyang Xiong et al.
    Mechanical interactions between bacterial species with different motility characteristics play an important role in spatial-temporal dynamics of multi-species bacterial colonies and can lead to formation of complex patterns.

    Antibacterial gene transfer across the tree of life

    Jason A Metcalf et al.
    Parallel horizontal gene transfer has spread a bacteriolytic gene family to all domains of life, and has bestowed a niche-transcending adaptation in recipients that must deploy antibacterial molecules to survive in a bacterial world.
