Histograms showing relative transcriptional expression levels of three SbWRKY transcription factors and some defense-related genes in sorghum plants infected with Fusarium solani and/or treated with lavender essential oil at 1.5% after 3 and 6 days post-emergence (dpe). C: untreated control, P: infected with F. solani, EO: treated with lavender essential oil at 1.5%, and P + EO: infected with F. solani and treated with lavender essential oil at 1.5%. In each time for each studied gene, columns superscripted with the same letter are not significantly different according to Duncan’s multiple range test (P ≤ 0.05). Each value represents the mean of three biological replicates; each sample was analyzed in triplicate. Error bars represent standard errors.
