Volcano plots comparing differential gene expression between resistant or susceptible sample types at different stages of infection. A cutoff fold change of |1.5| and p-value of </= 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. A-C, resistant comparisons. D-F, susceptible comparisons. A, NL1-RHg12h vs NL1-RHg3d; B, NL1-RHg12h vs NL1-RHg8d; C, NL1-RHg3d vs NL1-RHg8d; D, TN812h vs TN83d; E, TN812h vs TN88d; F, TN83d vs TN88d.
