The vte2-2 mutant is not generally impaired in the production of defense-related metabolites but exhibits attenuated SA biosynthesis. Endogenous levels are shown for defense-related metabolites at 24 h post Psm inoculation or 10 mm MgCl₂ infiltration in leaves of Col-0 and vte2-2 mutant plants. Values given represent means ± sd of four replicate leaf samples. nd, not detected. Other details are as described in Figure 3. Asterisks above the brackets denote statistically significant differences between the Psm samples of Col-0 and vte2-2: ***, P < 0.001; **, P < 0.01; and *, P < 0.05 (two-tailed Student’s t test).
