BAI3∆talD loses avirulence on IR64 but BAI3∆talI and BAI3∆talF do not on CT13432 and FKR47N. A Leaves of IR64 and Azucena were challenged with Xoo strains BAI3, and BAI3ΔtalD carrying an empty vector (EV) or a plasmid with talD (ptalD). To assess significance, the parametrical test ANOVA (α = 0.05) was carried out using the R package. Values labeled with the same lower-case letter are not significantly different. B Leaves of rice varieties CT13432, and FKR47N were clip-inoculated with the wild-type African Xoo strain BAI3 and with mutant strains BAI3ΔtalI and BAI3ΔtalF, respectively. Azucena was included for all strains as a susceptible check. Lesion lengths were measured at 15 dpi. Data are the mean of eight measurements. Error bars represent ± SD. Significant differences (p < 0.001) were determined using an unpaired two-sample t-test, bars with « ns » are not statistically different. Experiments were repeated three time with similar results
