    Phylogenomic analysis supports the ancestral presence of LPS-outer membranes in the Firmicutes

    Luisa CS Antunes et al.
    Phylogenomics provides support for the Gram-positive type of bacterial cell envelope being a derived character that arose independently multiple times through loss of an ancestral outer membrane.

    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.

    An essential Staphylococcus aureus cell division protein directly regulates FtsZ dynamics

    Prahathees J Eswara et al.
    GpsB in Staphylococcus aureus directly regulates the central cell division protein FtsZ, a different function from that assigned for GpsB in other closely related organisms.

    The genomes of polyextremophilic cyanidiales contain 1% horizontally transferred genes with diverse adaptive functions

    Alessandro W Rossoni et al.
    Horizontal gene transfer (HGT) analysis in polyextremophile red algae (Cyanidiales) provides explanations for the nonexistence of cumulative effects and eukaryotic pangenomes, and highlights differences between HGT and native genes.

    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 contribution to genesis of the novel germ line determinant oskar

    Leo Blondel et al.
    Evidence suggests that the oskar gene, a critical germ line determinant in insects, was formed by fusion of bacterial and eukaryotic sequences at least 450 million years ago.

    Homeostatic control of cell wall hydrolysis by the WalRK two-component signaling pathway in Bacillus subtilis

    Genevieve S Dobihal et al.
    Molecular genetic analyses define the first homeostatic control pathway that maintains cell wall remodeling activity during bacterial growth.

    The lost world of Cuatro Ciénegas Basin, a relictual bacterial niche in a desert oasis

    Valeria Souza et al.
    At Cuatro Ciénegas, the ancestral niche conditions of the ancient shores of Laurentia persisted along with its microbial communities that have been coevolving for a very long time.
