Fig 7. PR1 expression in plants inoculated by ald mutants and growth of ald mutants on SA-deficient sid2-2 plants.
A) PR1 expression in Col-0 plants at 24 hrs following syringe infiltration (OD600 = 1x10-5). Significant elevation of PR1 expression in aldA-infected plants was observed in three independent experiments, and in two experiments for aldB-infected plants. B) Growth of ald single and double mutants on wild type A. thaliana (Col-0) and sid2-2 mutant plants following syringe infiltration. Graph shows composite data from 4 independent experiments. Letters indicate significant difference between samples within a given time point (p<0.02).
