  1. HPLC analysis of ferulic acid, p-coumaric acid, vanillin and p-hydroxybenzaldehyde contents in the cell wall-bound fraction of control and V. dahliae-inoculated resistant (LA3038) and susceptible (LA3030) tomato roots. The results are the mean values of three independent assays. Hpi: hours post-inoculation; C: control plants; I: inoculated plants; FW: fresh weight. Means followed by * are significantly different from the control group mean for that time point (P < 0.05).
