Figure 4.
Schematic illustration of reinfection/sporulation assay. (a): wild type bacteria infect cured fungi, migrate into sporangia, trigger formation of sporangiospores and enter the spores. (b): T3SS mutants enter hyphae, but reach lower cell densities and fail to elicit sporulation. (c): cured fungi are incapable of forming mature sporangia and sporangiospores. Premature sporangia can be detected sporadically.
