    Ecological feedback in quorum-sensing microbial populations can induce heterogeneous production of autoinducers

    Matthias Bauer et al.
    Quorum sensing enables heterogeneous production of autoinducers in microbial populations, suggesting an alternative mechanism to stochastic gene expression in bistable gene-regulatory circuits to control phenotypic heterogeneity.

    Quorum sensing controls Vibrio cholerae multicellular aggregate formation

    Matthew Jemielita et al.
    A quorum-sensing-controlled program of multicellularity, aggregation, is identified in Vibrio cholerae, which may be important for transitions between the marine niche and the human host.

    An atypical DYRK kinase connects quorum-sensing with posttranscriptional gene regulation in Trypanosoma brucei

    Mathieu Cayla et al.
    A trypanosome DYRK kinase that exhibits fundamental differences to conventional DYRK family regulation links parasite quorum sensing, signal transduction and developmental gene expression.

    Quorum sensing control of Type VI secretion factors restricts the proliferation of quorum-sensing mutants

    Charlotte Majerczyk et al.
    Quorum-sensing control of Burkholderia thailandensis toxin and immunity pairs serves to police quorum-sensing mutants and may represent a general strategy whereby cooperators can police mutants.

    Regulation by the quorum sensor from Vibrio indicates a receptor function for the membrane anchors of adenylate cyclases

    Stephanie Beltz et al.
    A canonical class III adenylate cyclase with a membrane anchor of six transmembrane spans is regulated by a receptor of similar design, the quorum-sensing receptor from Vibrio harveyi.

    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.

    Quorums enable optimal pooling of independent judgements in biological systems

    James AR Marshall et al.
    Consideration of signal detection theory shows how decision ecology relates to optimal collective decisions, helping explain the prevalence of quorum-sensing in even the simplest collective systems, such as bacterial communities.

    Ciona intestinalis illustration

    The Natural History of Model Organisms: An organismal perspective on C. intestinalis development, origins and diversification

    Matthew J Kourakis, William C Smith
    The life cycle and morphology of the sea squirt Ciona intestinalis shed light on vertebrate evolution.
  1. Research Culture: Setting the right tone

    Tanita Casci, Elizabeth Adams
    Improving the research culture of an institution may lead to a fairer, more rewarding and successful environment, but how do you start making changes?
  2. Point of View: Priority of discovery in the life sciences

    Ronald D Vale, Anthony A Hyman
    Disclosing work prior to submission to a journal would benefit scientists seeking to be acknowledged for their discoveries.
