Effects of exogenous abscisic acid (ABA) on the induced resistance against B. cinerea and Pst DC3000 in Arabidopsis. Col-0 plants were treated with 100 µM ABA solution at the root level. After 48 h, the leaves were drop-inoculated with B. cinerea or sprayed with Pst DC3000. Disease incidence and severity caused by B. cinerea (A,B) and Pst DC3000 (C,D) were assessed at 4 days post infection. Data are mean ± SE from three repetitions with 12 plants/treatment. Ns indicates no significant difference (Duncan test, p < 0.05).
