    A regulatory pathway that selectively up-regulates elongasome function in the absence of class A PBPs

    Yesha Patel et al.
    Balanced peptidoglycan synthesis requires regulators, including sigma-I and WalKR, that coordinate the diffusive action of class A PBPs and the directional motion of the MreB-directed elongasome.

    HetL, HetR and PatS form a reaction-diffusion system to control pattern formation in the cyanobacterium nostoc PCC 7120

    Xiaomei Xu et al.
    Genetic, biochemistry and modeling approaches reveal elements of a Turing-type reaction-diffusion system to control pattern formation in differentiating cyanobacterial filaments.

    Flotillin-mediated membrane fluidity controls peptidoglycan synthesis and MreB movement

    Aleksandra Zielińska et al.
    Correct cell wall synthesis in bacteria depends on flotillin-mediated membrane fluidity.

    An ECF-type transporter scavenges heme to overcome iron-limitation in Staphylococcus lugdunensis

    Angelika Jochim et al.
    An ECF-type transporter serves as broad-spectrum heme iron scavenger and allows an opportunistic pathogen to use multiple eukaryotic hemoproteins to overcome nutritional iron-limitation.

    PrkA controls peptidoglycan biosynthesis through the essential phosphorylation of ReoM

    Sabrina Wamp et al.
    Analysis of suppressor mutants led to the identification of a novel signalling pathway that regulates peptidoglycan biosynthesis in Gram-positive bacteria.

    Global phenotypic profiling identifies a conserved actinobacterial cofactor for a bifunctional PBP-type cell wall synthase

    Joel W Sher et al.
    A broadly useful phenotypic profiling dataset was generated and used to identify a cofactor required for a polar cell wall synthase in Corynebacterium glutamicum that is conserved throughout the Actinobacteria.

    Bacteria: Driving polar growth

    Neeraj Dhar
    Profiling the phenotype of 200,000 mutants revealed a new cofactor that may help a group of rod-shaped bacteria elongate and grow.

    Dominant Vibrio cholerae phage exhibits lysis inhibition sensitive to disruption by a defensive phage satellite

    Stephanie G Hays, Kimberley D Seed
    Genetic and molecular analyses identify and characterize an evolutionary battle over lysis timing wherein a bacteriophage delays lysis through lysis inhibition while a defensive phage satellite accelerates lysis.

    Highly regulated, diversifying NTP-dependent biological conflict systems with implications for the emergence of multicellularity

    Gurmeet Kaur et al.
    Multicellular and socially aggregating prokaryotes contain previously undescribed, chaperone-based systems predicted to mediate defensive biological conflicts, several components of which are thematically similar antecedents of eukaryotic apoptosis pathways.

    Cell-type diversity and regionalized gene expression in the planarian intestine

    David J Forsthoefel et al.
    Application of laser-capture microdissection to planarian intestinal tissue provides a new tool for analysis of tissue-specific gene expression in flatworms, and a new resource to advance investigations of gastrointestinal regeneration.
