Assemblage mobility, bacterial hitchhiking, and spatial growth dynamics. Confocal image time series (xz-projections) for growing interkingdom assemblages. (A) Interkingdom assemblage displays a leaping-like motion. White lines indicate the leading edge of the growing assemblage. White thin arrows indicate the direction of fungal hyphal elongation toward the surface. (B) Walking-like motion. White arrowheads, newly formed fungal hyphae stablish new anchoring points on the surface. Green, S. mutans; cyan, C. albicans. Yellow thick arrows, moving directions of the assemblage. Abbreviation: C.a., C. albicans. (Scale bar, 50 μm.)
