    CryoEM and computer simulations reveal a novel kinase conformational switch in bacterial chemotaxis signaling

    C Keith Cassidy et al.
    An atomic model of the bacterial chemosensory array obtained through the synthesis of cryo-electron tomography and large-scale molecular-dynamics simulations reveals a new kinase conformation during signaling events.

    Adaptability of non-genetic diversity in bacterial chemotaxis

    Nicholas W Frankel et al.
    An experimentally constrained model shows that Escherichia coli faces fitness trade-offs in chemotaxis behaviors, and that adaptation of phenotypic diversity through altered gene regulation permits populations to resolve these trade-offs.

    Multiple sources of slow activity fluctuations in a bacterial chemosensory network

    Remy Colin et al.
    Single-cell FRET measurements reveal large temporal activity fluctuations within this signaling pathway in Escherichia coli, caused by stochasticity of receptor methylation combined with allosteric interactions and slow rearrangements within receptor clusters.

    Chemotactic network responses to live bacteria show independence of phagocytosis from chemoreceptor sensing

    Netra Pal Meena, Alan R Kimmel
    Eukaryotic chemotaxis to live bacteria was quantified at a high throughput level, for the first time, and mechanistically examined for the interrelationship between chemotaxis and phagocytosis.

    Asymmetric random walks reveal that the chemotaxis network modulates flagellar rotational bias in Helicobacter pylori

    Jyot D Antani et al.
    Asymmetric forward and backward swimming speeds reveal that the rotational bias, and not reversal frequencies, is an appropriate measure of chemotaxis signaling in Helicobacter pylori..

    Phenotypic diversity and temporal variability in a bacterial signaling network revealed by single-cell FRET

    Johannes M Keegstra et al.
    Noise in a signaling network comprising thousands of molecules shapes diversity across cell populations and generates giant temporal fluctuations at the single-cell level.

    Cyclic di-GMP differentially tunes a bacterial flagellar motor through a novel class of CheY-like regulators

    Jutta Nesper et al.
    Precise control of the bacterial flagellar motor determines bacterial cell dispersal and bacteria-surface interactions.

    Environment determines evolutionary trajectory in a constrained phenotypic space

    David T Fraebel et al.
    Experimental evolution shows that when selection acts on two traits constrained by a trade-off, the direction of phenotypic evolution depends on the environment.
