NPR1 and infection: Regarding the SA pathway, NPR1 (GSVIVT01015181001, Additional file 11: Data S9) and TGA4 (GSVIVT01033632001, Additional file 11: Data S9) were significantly up-regulated in ZX and peaked at 48 h post infection; in VT, NPR1 was repressed at 48 h after infection, and no significant difference was evidenced for TGA4. The expression level of these two genes was higher in ZX than in VT from 48 to 72 h post infection (Fig. 6).
