    Evolution of the complex transcription network controlling biofilm formation in Candida species

    Eugenio Mancera, Isabel Nocedal ... Alexander D Johnson
    The transcription networks controlling biofilm formation in Candida species exhibit 'structural' similarities, but show gradual substitutions of transcription regulators and frequent changes in target genes.

    Structural basis of host recognition and biofilm formation by Salmonella Saf pili

    Longhui Zeng, Li Zhang ... Guoyu Meng
    SafDAA-SafDAA structure and functional characterizations reveal a pili-mediated inter-cellular oligomerization mechanism for bacterial aggregation and biofilm formation in Salmonella enterica.

    A biophysical threshold for biofilm formation

    Jenna A Moore-Ott, Selena Chiu ... Sujit S Datta
    A biophysical model of the process by which bacteria transition from the motile planktonic state to the immobilized biofilm state yields testable predictions in terms of two dimensionless parameters, one describing nutrient availability and the other describing cellular dispersal.

    Mechanistic insight into the conserved allosteric regulation of periplasmic proteolysis by the signaling molecule cyclic-di-GMP

    Debashree Chatterjee, Richard B Cooley ... Holger Sondermann
    Structure-function analyses reveal the mechanistic underpinnings of inside-out transmembrane signaling that controls periplasmic proteolysis, and thereby biofilm formation, in bacteria and may be relevant in the context of other signaling proteins with similar control elements.

    Impaired respiration elicits SrrAB-dependent programmed cell lysis and biofilm formation in Staphylococcus aureus

    Ameya A Mashruwala, Adriana van de Guchte, Jeffrey M Boyd
    The absence of oxygen prompts Staphylococcus aureus cells to rupture resulting in increased formation of biofilms, which are the etiological agents of recurrent infections.

    Cross-talk between individual phenol-soluble modulins in Staphylococcus aureus biofilm enables rapid and efficient amyloid formation

    Masihuz Zaman, Maria Andreasen
    Inter-molecular cross-seeding between phenol-soluble modulins facilitates rapid and efficient self-assembly in Staphylococcus aureus biofilms revealing a complex molecular interplay between distinct phenol-soluble modulins orchestrating functional amyloid formation.

    Substrate stiffness impacts early biofilm formation by modulating Pseudomonas aeruginosa twitching motility

    Sofia Gomez, Lionel Bureau ... Sigolene Lecuyer
    The spatial organization of pathogenic bacteria into microcolonies can be shaped by the stiffness of the substrate that they colonize, via modifications of the bacterial motility.

    Heterogeneity in surface sensing suggests a division of labor in Pseudomonas aeruginosa populations

    Catherine R Armbruster, Calvin K Lee ... Matthew R Parsek
    Subpopulations of polysaccharide producer and surface explorer cells play specialized roles in early Pseudomonas aeruginosa biofilm formation.

    A serine sensor for multicellularity in a bacterium

    Arvind R Subramaniam, Aaron DeLoughery ... Yunrong Chai
    Biofilm formation by Bacillus subtilis relies on a sensing mechanism for the amino acid serine that does not depend on a dedicated protein or RNA.

    Structural foundation for the role of enterococcal PrgB in conjugation, biofilm formation, and virulence

    Wei-Sheng Sun, Lena Lassinantti ... Ronnie P-A Berntsson
    The enterococcal adhesin PrgB consists of four immunoglobulin-like domains that support the proper function of its polymer adhesin domain.
