Volcano plots comparing differential gene expression between NH1-RHg (R) and TN8 (S) sample types. A cutoff of ≥ |1.5| fold cutoff and P ≤ 0.05 was used for the analyses. Induced genes (dark blue, upper right quadrant) are genes induced during the resistant reaction. Suppressed genes (dark blue, upper left quadrant) are genes suppressed during the resistant reaction. The differentially expressed genes are presented in context for NH1-RHg. A, L2 (pi-L2); B, 12 h (i-L212h); C, 3d (i-L23d); D, 8d (i-L2/L38d).
