Fig. 5. Expression levels of defense-related genes in Zantedeschia aethiopica (ZA) or “Captain Romance” (CR) in response to Pectobacterium brasiliense (Pb) inoculation.
Leaf inoculation was made with 100 µl of bacterial suspension (106 CFU/ml, OD600 = 0.001) or distilled water (control, C). Relative transcripts levels were determined for lox2, ast, pal, and pr1, and normalized to tubulin. Bars represent the mean relative expression ± SD of two independent experiments with three replicates. Bars not labeled by the same mark indicate a significant difference (P < 0.05)
