Figure 3. Anthocyanin accumulation reduces cell death in Petunia and Arabidopsis.

(a–h) Differences in disease symptoms between two Petunia cultivars, Vakara Blue and Vakara White. (i) Trypan blue staining assays in healthy and OY-W infected Arabidopsis wild type and chs mutant. The values of signal intensity detected by trypan blue staining were calculated by image J. The relative signal intensities are means of 3 samples, with standard error of the mean. Significant difference between infected WT and infected chs is indicated as * (P < 0.05).
