Temporal expression patterns of the DEGs in sweet potato leaves damaged by MW. Relative gene expression measured by qRT-PCR at 0.25, 0.5 and 6 h, comparing untreated leaves (cK) and leaves damaged by MW. (A-E) Up-regulated genes: JA-induced WRKY, MYC2, MYC4, JAZ1-TIFY-10A, and JAZ2-TIFY-10B. (F-J) Down-regulated genes: CNGC, CaM, NPR1, TGA, and JAZ6-TIFY-11B. Error bars indicate the standard deviations for the means of triplicate samples, and the Act2 gene was used for data normalization. Asterisks indicate statistically significant differences. (Dunnett’s multiple comparison test,* represents P < 0.05; ** represents P < 0.01; *** represents P < 0.001; ‘ns’ not significant represents P > 0.05). The results are representative of three replicates.
