Figure 6: The effects of M. persicae feeding and methyl jasmonate (MeJA) or salicylic acid (SA) treatment on glucosinolate concentration in plant leaves.

(a,b) M. persicae feeding increased indole glucosinolate concentration in plant leaves. **P < 0.01; Student’s t-test. (c,d) MeJA and SA treatment on glucosinolate concentration in plant leaves. Kruskal-Wallis test. Different letters above bars indicate significant difference at P < 0.05. Values shown are mean ± SE. Glucosinolate side chain abbreviations: 4MTB, 4-methylsulfinylbutyl; I3M, indol-3-ylmethyl; 4MI3M, 4-methoxyindol-3-ylmethyl; 4OHI3M, 4-hydroxyindol-3-ylmethyl; 1MI3M, 1-methoxyindol-3-ylmethyl.
