Content of Signaling Molecules Involved in Pathogen Defense after Inoculation of Agrobacterium.

Arabidopsis inflorescence stalks were inoculated with either strain C58 or GV3101 for 3 h, 6 d, and 35 d (tumor).

(A) and (B) Levels of ACC, a precursor for ET biosynthesis. Note the different scale of the ordinate in graph (B).

(C) to (E) Levels of SA (C), OPDA (D), a precursor of JA biosynthesis, and JA (E). Results are given in pmol per g fresh weight (FW). Bars represent mean values (±sd) of five independent experiments.
