Expression of the Xa27 gene confers enhanced resistance to Xanthomonas oryzae pv. oryzicola (Xoc) L8. (A) Phenotype of bacterial leaf streak on leaves of BC3F1 plants of IRBB27 × Control (leaf 1), IR24 × L24 (leaf 2) and IRBB27 × L24 (leaf 3) at 10 days after inoculation (DAI) with Xoc L8. Control, control transgenic plant derived from the transformation of Nipponbare with empty vector pC1305.1. (B) Bacterial population of Xoc L8 in leaves of BC3F1 plants of IRBB27 × Control, IR24 × L24 and IRBB27 × L24 over 10 days by syringe infiltration. (C) Phenotype of bacterial leaf streak on leaves of IRBB27 plants at 3 DAI (leaves 1 and 2) and 10 DAI (leaves 3 and 4) with Xoc strains L8(pHM1) (leaves 1 and 3) and L8(pHM1avrXa27) (leaves 2 and 4). (D) Bacterial population of Xoc strains L8(pHM1) and L8(pHM1avrXa27) in leaves of IRBB27 plants over 10 days by syringe infiltration. (E) Induction of Xa27 in leaves of IRBB27 plants by inoculation with Xoc strains. Lane 1, noninoculated IRBB27 plants; lane 2, IRBB27 plants infiltrated with Xoc L8(pHM1) at 3 DAI; lane 3, IRBB27 plants infiltrated with Xoc L8(pHM1avrXa27) at 3 DAI.
