Fig 8. Virulence of efpR mutants and complemented strains vs the WT strain, on tomato plants.

The data are represented as the hazard ratio between the tested strain and WT strain. The death rates of plants inoculated by soil drenching with the efpR mutants are significantly lower than the death rates of those inoculated with the WT strain, while the complemented mutant shows no significant difference with the WT strain (One sample t-test, comparison with the WT strain, * p-value <0.05, **p-value <0.01).
