Virulence assay of R. solanacearum T3Es mutants with deletion of more core and extended T3Es. OE1-1; RK7147 (Dgala Dskwp Dhlk Dawr, deletion of 15 more core T3Es, OE1-1D36E); RK7161 (Dgala Dskwp Dhlk Dawr, deletion of 15 core and six more extended T3Es deletion, OE1-1D42E) were used. Bacterial cells were infiltrated into (A,B) tobacco and (C) eggplants (S. melongena cv. Senryo-nigou). Wilt symptoms were inspected daily and scored on a disease index scale from 0 to 4. Each assay was repeated with at least four biological replicates using 12 plants per trial. The mean values of all experiments were averaged with SE. A t-test was conducted each day, and asterisks indicated a significant difference (p < 0.05).
