Figure 8.
Disease ratings of dnd1 double and triple mutants inoculated with B. cinerea. Two-month-old plants were inoculated with 2 × 105 B. cinerea spores/ml and rated for disease symptoms 3 dpi. Mean ± SE of disease ratings from three independent experiments are shown for all lines except dnd1 npr1 ein2, which lacks SE data because only two replicates were completed. Asterisks identify severity scores that were significantly different from the left-most line with same shading (Col-0, dnd1 or dnd2), determined by ANOVA (P < 0.05; Tukey test). Disease rating scale: 0 = no disease, 6 = extensive disease (see Methods).
