Identification of carvone- and P. massoniana-induced genes (all figures were generated by the authors of this study). a. Scatter plot of the gene expression of P. massoniana-induced and carvone-induced genes in Treatment 1 and Treatment 2 libraries according to the log2fold change of normalized reads and the -log10fold change of the p-value (t-test, n = 3). Expression levels are normalized by the mean numbers of transcripts per million clean reads (TPM). Data points colored blue, red or black represent suppressed genes, promoted genes or nonsignificant differentially expressed genes. b. The intersections of lists of P. massoniana-induced and carvone-induced genes. The Venn diagram displays the distribution of 3571 unique genes from Treatment 1 and 3434 unique genes from Treatment 2. S1 and S2 represent suppressed genes (log2fold < − 1, p < 0.05 and FDR < 0.05). U1 and U2 represent unchanged genes (− 1 < log2fold < 1 or p > 0.05). P1 and P2 represent promoted genes (log2fold > 1, p < 0.05 and FDR < 0.05). c. Profiles of genes that show the same expression change trends when induced by both Pinus massoniana and carvone. Treatment 1: Induction of B. xylophilus gene expression by P. massoniana. Treatment 2: Induction of B. xylophilus gene expression by carvone
