Figure 5

Knockout of T6SS gene cluster MXAN_4800-4813(Δt6ss) for assessment of its role in the boundary formation. A visible boundary appeared at the point of interaction between DK1622 and ΔMXAN_0049 (A). When DK1622 interacted with Δt6ss, no boundary formed (B). Similarly, in the case of ΔMXAN_0049 and Δt6ss interaction, no boundary appeared (C). When all three strains, ΔMXAN_0049, Δt6ss, and DK1622, interacted with each other on the same plate, only a visible boundary appeared in the case of DK1622 and ΔMXAN_0049 at the point of interaction (D).
