Disease evaluation standards: HR, highly resistant plants with a DI value between 0 and 10.0; R, resistant plants with a DI value between 10.1 and 20.0; T, disease tolerance plants with a DI value between 20.1 and 35.0; S, susceptible plants with a DI value >35.0. The means standard deviations (SD) were calculated based on three replications. Asterisks indicate statistical significance (P<0.05) between the control plant(z99668) and each transgenic lines (KB1, KB2 and KB3).
