(a) Progression of wilt symptoms in tomato plants inoculated with the wild‐type strain, the ΔchsV mutant or simultaneously with both strains in different conditions. The severity of disease symptoms was recorded at different times after inoculation, using an index ranging from 1 (healthy plant) to 5 (dead plant). (b) Progression of wilt symptoms in tomato plants singly inoculated with the wild‐type strain, the Δgas1 mutant or the Δfmk1 mutant, or co‐inoculated as indicated. Error bars indicate the standard deviations from three independent experiments, each including 15 plants per treatment. See Table 1 for statistical analysis of the data.
