Protective Effect of flg22 Is Compromised in exo70B2 Mutants.
Growth of Pst on Col-0, pub22 pub23 pub24, exo70B2-1, and exo70B2-3 plants pretreated with water or 100 nM flg22 for 24 h and then syringe infiltrated with 1 × 106 cfu/mL of bacteria. Bacterial growth was determined 2 d after inoculation. Data are shown as the mean of three independent experiments ± se (n = 18). Statistical significance between samples is indicated by brackets and asterisks (Student’s t test; **P < 0.01 and ***P < 0.001).
