    A receptor-like kinase mutant with absent endodermal diffusion barrier displays selective nutrient homeostasis defects

    Alexandre Pfister et al.
    The SCHENGEN3 protein is needed for the progression of isolated microdomains into a continuous band, which is necessary for the establishment of the major extracellular diffusion barrier in plant roots: the Casparian strip.

    Integrin-based diffusion barrier separates membrane domains enabling the formation of microbiostatic frustrated phagosomes

    Michelle E Maxson et al.
    The diffusional barrier formed between phagocyte integrin and fungal glucans preserves the microbiostatic phagocytic environment generated during the frustrated phagocytosis of Candida albicans hypha.

    Intracellular Diffusion: How bacteria keep proteins moving

    Conrad W Mullineaux
    Bacteria contain large numbers of negatively-charged proteins to avoid the electrostatic interactions with ribosomes that would dramatically reduce protein diffusion.

    Dynamics of BMP signaling and distribution during zebrafish dorsal-ventral patterning

    Autumn P Pomreinke et al.
    Patterning of the dorsal-ventral axis in zebrafish is mediated by a graded source-sink mechanism in which diffusing BMP, produced from a ventrally biased source, is inhibited by dorsally-produced chordin.

    Exploratory search during directed navigation in C. elegans and Drosophila larva

    Mason Klein et al.
    Crawling Drosophila larvae and C. elegans exhibit diffusive behavior alongside directed motion, and the dynamics of this navigation can be analyzed with techniques developed in understanding protein folding, using a Markov state model.

    Systems biology derived source-sink mechanism of BMP gradient formation

    Joseph Zinski et al.
    Embryo-wide quantitative analysis of BMP signaling in zebrafish embryos, combined with a mathematical model-based computational screen, challenges the prevailing model of an antagonist counter-gradient shaping the gastrula BMP morphogen gradient and supports an antagonist sink with BMP diffusion mechanism.

    Length-dependent flagellar growth of Vibrio alginolyticus revealed by real time fluorescent imaging

    Meiting Chen et al.
    The length-dependent growth rate of bacterial flagellar filament is determined by the flagellin loading speed, loading strength and its diffusion process.

    Cell-sized confinement controls generation and stability of a protein wave for spatiotemporal regulation in cells

    Shunshi Kohyama et al.
    A cell-sized fully confined space significantly controls the emergence and stability of a protein wave, resulting in intracellular spatiotemporal regulation driven by a reaction-diffusion mechanism.

    Ribosome surface properties may impose limits on the nature of the cytoplasmic proteome

    Paul E Schavemaker et al.
    The diffusion coefficients of proteins in the cytoplasm depend on their net charge and the distribution of charge over the protein surface, with positive proteins moving up to 100-fold slower because they bind to ribosomes.

    Design of biochemical pattern forming systems from minimal motifs

    Philipp Glock et al.
    Theoretical analysis and in vitro reconstitution of a biological reaction-diffusion system identify key functional motifs as well as underlying principles and enable rebuilding pattern formation in a modular fashion.
