FIGURE 1

Schematic representation of different bacterial type III secretion systems (T3SS). (A) Illustrating the interactive roles of T3SS with potential eukaryotic hosts. (B) Depicting the potential role(s) of T3SS during interactions with fungi, on their surfaces, inside the hyphae and with spores. Triangles: different T3SS family; circles, rectangles: eukaryotic hosts. Branching: no evolutionary meaning implicated. Rhc, Rhizobia conserved; ChL, Chlamydiales; Sct, secretion and cellular translocation; SPI, Salmonella Pathogenicity Island; Hrp, hypersensitive response and pathogenicity. Thick solid line on top of (B) represents a plant root system demonstrating the mycorrhizal interaction.
