Activation of an ethylene/JA::GUS transgenic line of Arabidopsis (Pdf1.2) by GB03 VOCs, whereas other reporter transgenic lines (Pr-1a activated by SA and Jin14 activated by JA) were not activated by bacterial VOCs; the chemical elicitors SA and 1-aminocyclopropane-1-carboxylic acid (activate the Pr-1a gene and the Pdf1.2 gene respectively) were employed as positive controls, and DH5α VOCs and water treatment served as negative controls. An asterisk indicates a significant difference between treated and control samples according to lsd at P = 0.05. Inset, Transgenic seedlings Pdf 1.2 exposed to GB03 volatiles (top) and water control (bottom).
